HS165 Insulating a solid wall (Do it yourself)

[@nowthenad3286]

I love everything about this video. I really like the way that my fellow Brits do videos. The Americans are just so smooth and glossy. I am especially grateful to see you overcome all of the little problems and for your explanations of how you saved money. BUT my absolute favourite is seeing that your wall looks great without the need to skim the entire wall. Thank you very much.

[@HaxbyShed]

Hi nowthenad, it's always rewarding to get nice comments thank you. You may know that my approach has caused some alarm from experts who are concerned that I would introduce serious problems with damp by using a non-breathable insulation. There certainly is that risk with my approach and I'm not going to say any opinion is right or wrong. We have not seen any problems yet outwardly after 14 months but I don't know what's going on behind the insulation (and I'm not taking it off to look). The room feels a lot warmer. I did a follow-up video with a thermal camera (HaxbyShed 226). Cheers

[@nowthenad3286]

@@HaxbyShed That is very conscientious of you to mention that. Don't worry though; I am just treating your video as food for thought. I shall take up some of these issues with the tech support staff from companies like Kingspan. I wonder why it is considered to be acceptable to use EPS/XPS tile backer boards + ceramic tiles if it is a problem to have a non-breathable insulation. I would have thought that it would be a good thing to have a vapour barrier to prevent moist air from getting through to the cold wall, leading to condensation and mould. Any moisture entering from outside could leave the same route it came - to the outside. Anyway, I obviously need to learn more about the science of this business.

[@Joshuagilchrist55]

This is how walls are done in NZ where I’m from I never understood the need for all the effort and mess with plastering. It always seemed like an unnecessary step in the building process. Our houses are strong and the finish lovely I wish the UK did more straight plasterboard walls. Also the plaster quality varies greatly here. I bought a new build and it looked like the plaster was out on by a kid with a wooden spoon.

[@HaxbyShed]

Hi Joshua, I have a few walls with just plasterboard, joint skim and paint. I suspect methods just get carried forward because that's how it's always done (speaking as a layman, you understand 😉). Cheers

[@gordyscotch]

Well done for tackling such a job on your own. To take the time to make a video of yourself doing it is going way above and beyond. My house is a 1970's build with solid no fines concrete external walls. It's a very cold house. I'm considering taking down the internal plasterboard, installing kingspan sheets and reboarding. Your video is inspirational.

[@HaxbyShed]

Well thank you very much for the compliment Gordon. I enjoy making videos so it's no trouble to me. I've insulated other walls which were much easier, because I did not have to hack the plaster off or get showered with 150 years of muck and crud falling in my face. Cheers.

[@johncowie3092]

I wouldn’t even take down the existing unless your rooms are small I strapped over the old wall the sf19 then plasterboard so warm now

[@kevinparkes4084]

It's never advisable to leave a gap in the insulation such as at the bottom of the boards, as this creates a cold spot. The moisture in the room air will tend to condense out at the cold spots leading to problems like black mould. You could always try dotting and dabbing with foam adhesive to fix the insulation to the bricks, instead of screwing through - the metal screws will act as a bridge conducting away heat, another source of damp problems

[@HaxbyShed]

Hi Kevin, I did not show it on the video but after some comments I injected foam at skirting level, but being careful not to blow the boards off 😁 Cheers

[@Hew.Jarsol]

Kingspan recommend a 5mm gap at the bottom.

The joys of an older property Paul. I have done something similar to the 4 rooms on the top attic floor of our house built in 1889 with 18" thick rubble filled solid stone walls. I didn't have your space issues, so battened with treated 3*2's and filled with 70mm Kingspan, then used the insulated plaster board on top to prevent cold bridging. Due to having high ceilings I put false ceiling joists up screwed to the existing joists through the lath and plaster and put 100mm of kingspan in the gaps and used 50mm insulated plasterboard over that. I know that when I did it, almost 25 years ago it exceeded building standards for new houses, I suspect it is not far off the latest regs. We don't need much extra heat in those rooms now, the radiators are tiny compared to the rest of the house. The last rooms that I did in a similar manner were the bathroom and toilet on the 1st floor, but I used rockwool instead, finished 18 months ago. Thats me finished with this house, the boys have left home, we no longer need 6 bedrooms, a 3 bedroom bungalow will do. With a MUCH BIGGER SHED.

[@HaxbyShed]

Hi Bill, 18 inch walls as late as 1889 that's pretty late for that sort of construction unless you lived deep in the country or remote parts. But high ceilings would be typical for that age. I think you may know the story that I chose this house for the outbuildings before my wife had seen it. Cheers

[@billdoodson4232]

@@HaxbyShed Haa haaaa haa "I chose this house for the outbuildings before my wife had seen it". Funnily enough one of the reasons I wanted this old pile was the fact it had full cellars with 8ft odd ceilings. All my woodworking stuff is downstairs, the metal working is all in the garage, erh workshop. Any of the houses round here built of stone by the Victorians have walls at least 18" thick. I can tell you that trying to diamond drill a 5" hole through them is a pain, an all day job.

[@stevetaylor7024]

Great video. I did the same to my cold walls before watching your video, except I used spray foam for the fixing. I sealed gaps with foil tape and around the edges with spray foam. I left a 12mm gap at floor level to prevent floor moisture ingress.

[@HaxbyShed]

Hi Steve, I know it's controversial using non breathable insulation but it's been fine for us. We've done the outside walls in a few rooms and even a thin sheet of insulation makes a big difference. Our heating costs are surprisingly low for an old house. Cheers

[@gordonmitchell729]

I’m glad I found your video Paul. My job will hopefully be easier as the walls are plastered to solid brickwork and quite smooth, but I have not done this before, so watching you tackle such a project has given me the confidence to crack on and insulate my property. Thank you for sharing this video.

[@HaxbyShed]

Thank you Gordon. There are vids on KZbin where they use the plasterboard backed with insulation and just 'dot and dab' it on the wall with adhesive foam, which makes it quite a quick job. I think they also put a couple of screws/fasteners in each panel for security. Mine was a more complicated case. Cheers

[@hashman27]

Fantastic video - thanks so much for sharing. All too often we just see professionally edited videos with ideal scenario rooms where everything fits together perfectly and seems easy and slick. The reality is that houses are like yours. Walls imperfect, holes in the walls, odd angles, etc. You were very thoughtful and resourceful and you set a great example for DIY enthusiasts. I was also glad to learn how much of a different insulation and plasterboard made to your home. I am planning on doing something very similar to mine! I'm sure your video will really help me!

The measuring up and out to ensure hitting the centre of a brick is simplified if you use a wooden batten as a staff and mark the drilling points onto the staff with a pencil.

[@HaxbyShed]

Howard, that's a good method. I think people always reach for what they know best and for me that's measurements and drawings so that's what did. And I usually cut my allowances too fine on DIY jobs. In my case it's measure twice, cut twice and then sand it to fit! Cheers

Great. Do note that several people have commented that my approach applied to a solid wall may cause condensation behind the (non breathable) insulation.

[@carlb401]

A little tip if you decide to do any more walls like this. You can get proper adhesive foam for gluing the sheets to the walls and the plasterboard to the insulation, it's not the normal expanding foam from the likes of screwfix etc, but a proper one for plaster boards etc. It will be easier than trying to screw it to the walls. Or if you want to carry on with screws get some insulation washers, they spread the load over the boards and don't pull through like screws on their own do.

[@HaxbyShed]

Hi carlb-photography, if I do any more I will try both those ideas, thanks. Cheers

[@Marenqo]

Was thinking the same, foam might be easier

[@mozzer999]

I've done a whole house back to brick and stuck the insulation boards on. A tip is to sbr the walls to stop the dust. You still need a few fixings to hold the boards back in case of fire.

[@coord47]

Great video. Well done. I did this to a bedroom that had 3 outside walls and was always colder than others. I used plenty of silicone filler of the back of the insulation boards and fixed it directly over the wallpaper on the wall! It worked well. I did not fit plasterboard. I simply painted over the insulation and it looks quite natural although It's a bit vulnerable to denting if you're not careful. Yes it made the room much warmer and easier to keep warm.

[@HaxbyShed]

Hi MintheM, I like your approach. Whatever works. I think people are too tied to convention when something simple would do just as well. Think - if we had no money we would find ways. Cheers

Well done for attempting this. One tip is to use diluted SBR on those bricks. It stabilizes the surface..and stops dusting. It can be use in cement to make it waterproof. You dont need steel to cover the cables as long as they are vertical or horizontal.

[@davidconstantine7315]

Well done Paul, a good job and a good video. I did a similar job throughout a small cottage bungalow that I rent out, Fortunately my walls were in a better state than yours and they had been "blackjacked" which had completely kept the damp out,so no problem in that respect. However, for anyone finding the drilling and plugging a bit of a hassle,or problem (such as loose areas) it is worth considering the "dot and dab" method, even if in just some places. The adhesive is very inexpensive, has a super adhesion once dry and it still sticks well to the aluminium backing sheet. The sheet can be gently tapped with a batten and hammer across it's face to get it seated nicely onto the wall. If not using any screw fixings the sheet can be held in place with a few masonry nails hammered loosely through a small thin plywood pad to hold the sheet in place , then removed later when adhesive is dry. This is quite a quick method of fixing and although more practical for the insulation already stuck to the plasterboard sheet, it would certainly help in those "hollow spots which are so difficult to get a good fixing. There's no doubt though that the finished job really improves the heat retention and comfort in any room,especially if done to all walls in a room. I also ripped out all the old windows and put in new double glazed ones, before I started on the insulated plasterboard. The difference in room temperature was incredible-------well worth the expense and effort-------for future tenants (and EPC?)

[@HaxbyShed]

Hi David, thanks for explaining. One or two people have mentioned that the EPC inspectors need proof of the work and, for example, just taking off a socket cover to show the insulation is not enough. So just be aware if you are counting on an EPC then I'd suggest finding out in advance what can be admitted as proof. Also I don't think their assessment software is very clever and I've heard of people spending a lot of money on improvements which have not counted because the standard assessment software can't deal with them. I once put just half an inch of foam insulation on a very cold solid wall and the difference was amazing. That was 10 years ago and I can confirm there has been absolutely no sign of damp or degradation of the outside brickwork. It might be different if the wall had rising damp to start with. Cheers

[@Chief81]

‘Especially done to all walls in a room’ don’t you just insulate exterior walls internally?

[@HaxbyShed]

@@Chief81 responding to your question there, people have said a solid wall without airflow will condensate on the inside, but also because the wall then holds more moisture it is then prone to frost damage and the brick faces spalling off. Now you can decide for yourself whether this view is real or just a theoretical risk but that's what I was covering off by referring to the outside (when I was insulating on the inside). Hope that makes sense. Cheers

[@JohnWilliams-vf5bt]

Well done sir, I’m in the middle of doing the same thing in our utility room so it’s fascinating watching how someone else tackles the job. I’ve used insulated plasterboard and sticky foam from Screwfix and I’m pleasantly surprised by the result. I’m happy to have a go at plastering myself so haven’t worried too much about lining up the front of the boards, although I know plastering is a skill I don’t think it’s beyond us keen diners.

[@HaxbyShed]

Hi John, I can 'patch plaster' ok if I can get the float across the gap or plaster to a batten. I think anything much larger I would struggle. If I did this again I may consider the sticky foam route although you may see from the comments that people are a bit concerned I fixed straight on to a single brick wall without battens. Cheers

Well done makes a massive difference to the warmth of a room just done this in 2 bedrooms however found it much easier and quicker to use adhesive foam to stick the boards to the walls no need to plaster them Americans do this all the time called drywall

[@HaxbyShed]

Hi, if I do another I may use the adhesive foam. It was just because I had always used screws before and I was reluctant to 'learn' adhesive foam for maybe the last wall I'm going to do. In UK we call the board itself Plasterboard, but when we use it to stick on a wall like that we call it 'dry lining' so in that way we do call it drywall. Maybe it's like like when people say "I'm making a film", it's not film these days at all but we still stay it. Sometimes there is no logic to these things - a hangover from an earlier time. 😁 Cheers

[@HaxbyShed]

Hi tnyima, it's a job I've been putting off for 10 years but the need to redecorate and the recent big increases in energy prices finally caused me to get it done. With insulation projects you can get as many opinions as there are people on the planet (like politics) but after 1 full year we have not seen any problems with damp or musty smells from condensation which could form on the wall behind the insulation, so I'm happy with it. Certainly we feel the benefit from a warmer room. Cheers

Well done, and thanks for taking the time to record it. I have been lubricating my screws with vaseline (I think someone has also suggested this) it certainly helps although you need to be careful not to overtighten.

I once owned a brick house in Stratford Ontario Canada. It was an old farmhouse that was around 100 years old. On the inside there was 2×4 studs with wood lathe and plaster with horse hair in the plaster, but no insulation. The heating bills where horrendous! In the winter at -20c we would get frost on the inside walls. I tore the lathe and plaster off- it was rather dodgy in areas, insulated with 4 " fiberglass bats R16, vapor barier and then used drywall board. It had a profound effect on the hesting bills and home comfort. And got rid of the old house smell!

In cold climates the modern prebuilt SIP insulated panel wall construction takes a lot of beating for its high insulation value. Creates a really cosy house with very low heating costs.

Hi Glenn, luckily we don't get it so cold here and most winters we only get a few days when the temperature is consistently below freezing. I've insulated many out-facing walls and roof spaces in this house over the years. No dramatic effects but I'm sure all the savings accumulate. Cheers

Hi, my insulated wall has been fine with no damp or mould or smells, but do please have a look through the comments and just give some though to damp if your wall is inclined to absorb a lot of moisture from outside or your house is humid inside. I visited a modern house recently which was very humid due to the 'lifestyle' of the occupants and there was water condensating on the toilet cistern, dripping off and running down through the ceiling below. There was also water condensating and dripping from the loft hatches. I'd never seen anything like it - unbelievable! I'm not suggesting you live like that of course, I'm just highlighting that lifestyle and ventilation are big factors in these things. What is fine for one family may not be ok for another. Cheers

[@hhandcarte4473]

Thanks, this room is the only warm one in the house we have a multi fuel stove running in there, and it is the living room so I avoid drying clothes etc. Just a question, I suspect that you couldn’t use this method to insulate if the exterior wall is rendered and painted ..🤔 as the moisture has to come out on the brick somewhere…?

Im debating whether to put some 25mm silver backed insulate, but ive learnt a lot about these solid walls and allowing moisture to pass through both ways is a must for them to breathe so im put two decent vents in the new boards to allow damp to pass through and allow circulation. Like you say these old houses are an absolute pain

Well as a DIYer, you've done a decent job on an awkward wall there. I've been in the trade over 50 years and I did exactly the same to my external walls when I moved in here 17 years ago. My bills are less than half my next door neighbour's and it's always cosy. Just one hint that might help: you don't actually need to screw, into plugs. If you use a 5.5mm drill and red plugs, you can push the plug through both plasterboard and insulation with a 5 mm drift (rod or another drill bit) until you feel it's gone home. Then use a 65mm galvanised clout head nail and gently tap it home. Do that at 600mm centres up the edge, and a line up the middle, if you're skimming it. But you will need to use scrim over the nail heads, or you'll get nail pops in places. Well done, anyway 👍

Hi Matty thanks for watching that. Some viewers like a bit of DIY thrown in and some don't. The postman has just delivered the chosen curtains and she'll pick out some colours. Last time we did that bedroom she told me what paint to buy but I found some a bit cheaper - red is red right? Wrong I was told. Anyhow what's bought is bought and I think the crappy curtains were payback for my paint colour mistake. This time I'll follow the instructions exactly. Cheers mate.

Boy, I don't envy you. Wife & I did the bath several years back, peeling off the tiles & drywalling / plastering. Walls were crooked & studs were randomly spaced. Three weeks & a hired plaster artist later, we swore never again. You did a great job solving the "little" problems that weren't little at all. I agree with Werner though. Canned PU foam would add stiffness & air tight insulation in all those gaps. Hope you're recoving mentally after this.

I used insulated plasterboard and used foam adhesive to stick it to wall. And then skimmed coat it. Easy and quick.

Hi Paul, great job. Been there with bells on lol, used to live in a stone and slate Scott's cottage built in 1760. Three foot thick walls all wringing wet, no fun.

[@dickiedubs3137]

I've been told you are meant to leave 25mm air gap each side of the foil....but in practice this is almost impossible so I'd still fix them directly to the wall. I had a similar problem with a boiler room in an outhouse. I needed some insulation but able still able to fix plywood to the wall to support a 40 kilo boiler. It turned into a real headache. A good product are hawkeng washers which spread the load of the screw

[@HaxbyShed]

Thank you Dickie for sharing that info. Cheers

[@iamkjb1]

It looks like a very dry and stable wall internally. If it were me, I would have timber studded the wall vertically, cut the insulation to fit vertically between the studs, then screwed the plasterboards over the top to the timber studs. I would have skimmed the plasterboard, but that's another story. Well done though. Also, you can get plaster stop bead.

[@HaxbyShed]

Hi Kev, unfortunately I just did not have the space for studding this time - you saw the plaster had to come off to get the space. I did think about sliding the wardrobes along a bit but they are right up against the door architrave now and that would have had to come off - the door is in the corner so I can't move it across. That strong binding tape seems to hold the boards together well and I don't expect cracking. Cheers

@@HaxbyShed Yes, I get that. We downsized to this 1960s house 7 years ago. I decided against solar and large-scale insulation improvements as I knew I would not get my money back, but now the sums have changed and in any case I think that comfort might be more important. But I dither on! :-).

Norman, my Dad lived into his 90s so at this point I might have 30 years or 30 minutes ....

Hi Ken, I've been doing selective insulation work all over the house for years but that bedroom was always going to be a big one. The only item left now is to improve insulation on the outside walls of a loft conversion (in the narrow roof space triangle) which at best is only covered with 2 inch fibre glass at the moment (floor to about 2 foot 6in vertical before the roof slope). I keep putting it off because it's a horrible job. Cheers

[@NAFO_Badger_Brigade]

I loved watching you have a go at this and use all the knowledge you had to solve the problem for YOURSELF. You're absolutely right in your approach. Here's a few reasons why: 1) get back to the brick structure and firm it up - great history lesson by the way 2) Amazing how 1inch of insulation can make a difference! The reason 50% of heat loss is covered by just 1 inch of insulation 3) You boldly went with your own experience and weren't put off by horror stories of damp! Surely the real knowledge is found on the frontline and not with the so called experts. I wondered - did u think of adding a thin foil wrap behind the insulation board to creep the R value up? Also - a tube of spray foam can be great to fill the gaps into plasterboard and save the mither of filling the gaps by other means! Thanks again!

[@HaxbyShed]

Thank you for your support Matthew. There are enough times when amateurs get it wrong but sometimes just by probability and persistence it works out and we defeat the odds. I've done a few walls in the home like this (just single walls not the whole room) and so far we have dodged the damp. That said, I do acknowledge now that breathable would be better on solid walls.

[@briangriffiths1285]

Bravo. The u-value of double brick solid walls can vary a lot but is generally over 2. Adding just 25 mm of PIR and plasterboard might well reduce that to .6 to .5 meaning that the heat loss is now a quarter of what it was. The latest building standard is .27 but starting with a blank canvas is easier!!

[@HaxbyShed]

Hi Brian, thanks. People have been concerned about condensation forming behind the boards and I'm sure the risk is real. But now we are 1 year on and so far I've not seen any problems. And the wall is a lot warmer and the room is more comfortable. Cheers Paul

[@briangriffiths1285]

@@HaxbyShed Thanks for responding. I was looking at a stone cottage in Scotland the other day (over the internet) and that was very damp inside. I have just come across this which talks of dealing with damp and solid walls! kzbin.info/www/bejne/oYizf2qZrdGaZ7c . To my mind a microporous paint or coating on the outside should deal with rain penetration whilst still allowing the walls to breathe. Whether you get direct rain against your wall is unlikely given you said it is close to the neighbours wall and that should help. But the foil backed PIR will form a solid barrier. I saw someone using wood fibre insulation in a single wall damp situation?

@@HaxbyShed Blue in a bedroom!!!, very brave. I like your logic with that point system you've got going on. If I adopted that same system I would be winning without any doubts. I enjoyed watching your video, it's nice to watch other people such as yourself tackling jobs. Your video reminded me of a supposedly easy job that I did for our lass. She wanted her bedroom ceiling painting so I readily offered my service, I masked all around the top of the walls then preceded to paint. Immediately after painting I peeled away the masking tape mostly without any issue. When I peeled it away from her wall paper, the paper came off with it. I started to chuckle to myself because I knew what trouble I was then in. I convinced R'lass that the best course of action would be to completely take off the old and then I would hang new paper. Her little face lighted up because she was getting more than she had asked for. That smile was soon going to disappear. I peeled back the paper, it was going well until a big patch of render came off with it. No worries I said to myself, I can soon fill that. More paper came off, more render too. Just like in your video, the whole wall was like sand. The misses came back from work and wondered why there was thirty bags of rubble on her drive. The wall was shot and the pointing was shot too. I had to rake it all out. When the little lady then saw the brickwork she fell in love with it so then another job started. I sanded the lot of it, blowing up her hoover in the process of cleaning the room. I varnished it three times and then used a red coloured mortar to point up. It looks bonny. The ceiling does needs another coat mind. Good luck in your future endeavours.

[@HaxbyShed]

I could tap quite a bit of plaster in this house and it is obviously loose so I did what any self-respecting tight Yorkshireman would do, I got my wife to paper over it with lining paper and painted it.

My house was built in the 1830’s so I have a similar situation. As it’s a solid stone wall which is porous, my understanding is that if you block the moisture by not using the correct product such as lime plaster or leave an air gap to allow for evaporation then you may be introducing the possibility of mould developing as the moisture has nowhere to go. I’m still trying to educate myself on this so I may be wrong.

[@HaxbyShed]

Hello Steve, the comments from people with more experience than me agree with you. Since it is a solid wall it seems an air gap is the correct approach. All I can say is I've used this method on a few walls in my house over the years without any problems that I'm aware of. Those walls have generally been sheltered. It seems having no air gap can cause problems but it's not a case that it definitely will cause problems, from my experience to date. Cheers

[@barneybiggles]

Yes, my house was built in 1725, handmade brick and lime mortar, problem is it’s been repointed in 1970 ( not me) using cement, probably because it’s cheaper than lime mortar, thinking of insulating the south facing gable end, not used often but I get in the winter 6 litres of water from a dehumidifier in that one room a day; if I was to insulate it where would all that 6 litres go?

[@davidhunt1760]

@@barneybiggles Hi, I have over 20yrs experience in drying buildings and can assure you your dehumidifier will always pull moisture. The 6 litres you are getting is most likely as a result of you living and breathing, taking showers, boiling the kettle etc etc. If you have a dog you will be astonished much moisture they breath out. Don't necessarily assume the water being collected is from your wall...hope this helps

[@michaeldavison8628]

Should use wood fibre insulation and lime plaster internally, don't use kingspan on old buildings, it seals in all the moisture of everyday living and will give you damp problems.

[@Rob-di7uu]

I also own old property, with some “blown “ plaster render. The external walls are solid double brick “no air gap” which I query when in past besieged by cavity wall sales people? When raking out plaster a large amount of old black render / filler is falling out is frightening, but like you I managed to repoint brick and re render with proper cement before plastering. I think it’s black ash or waist from local coal pits, and was used when house was built at the beginning of WW2 and obvious lack of materials, anything was used to bulk out mix. Now having watched your vid. the next project with be to added is internal insulation where possible 👍

[@HaxbyShed]

HI Rob, of course in-fill is not a new thing. Castle walls might be 12 feet thick but most of the middle was rubbish. I've seen cottage stone walls maybe 15in thick where the sold blocks on the outside were no more than facing 4 inch thick and back packed out with stone chips and mortar mix. Those clamp bricks are full of all sorts of rubbish like coal and ash - so much for old is best. Cheers

I've never had to do that kind of work on a house as old as yours, but our previous house had some interesting challenges. We redid the bathroom and removed all the plaster board off the walls. None of the exterior walls were insulated, so of course we added fiberglas. Made a big difference. Also, even though it is thin, the plasterboard (we call it drywall) also has an insulating value. I suspect that room will be more comfortable this winter without having to use as much energy to keep it warm.

[@HaxbyShed]

Hi Greg, I think the only 'upside' to old houses is character. Over here they can carry a purchase price premium as much as 50% for the size, they are poorly insulated, often the wiring and plumbing are dodgy and they can be damp. Buy one and you are likely to be lining yourself up for some work, and expense if you can't 'do it yourself'. But that was our choice, and if your wife can help then potentially that's good bonding 😁 Cheers

You have a fluent, articulate and thoughtful style that is a real pleasure to listen to. How wonderful to hear proper spoken English....and disappointing too, that its rarity nowadays leads this to be remarked upon. The content's good too - well-chosen words and no needless repetition. May I ask what it is that makes external insulation impractical for your wall? A blind external wall facing a neighbour sounds ideal and the thermal mass of the bricks inside the insulation would then buffer against temperatture variation inside, to further improve comfort. That said, you've sorted out your rubbish internal plaster and have regained a vertical internal wall. Six and two threes, as my father would likely say.

[@HaxbyShed]

Hi falfield, thank you for the compliments. The gap between the two houses is only about 15 inches (375mm). I am a slim guy and I can just about get down there sideways. Some years ago I had to remove a redundant 4inch vertical toilet pipe in that space and I had to make a bespoke wooden ladder with rungs just wide enough for one foot. I shimmied up sideways like a crab and sawed through the fixings with my arm out to the side. So it's just not feasible - no builder would entertain it. Cheers

[@falfield]

@@HaxbyShed Thank you for the reply. I agree of course that no builder would take this on, but did have one flight of fancy in case the gap transpired to be this narrow. It was to pump foam in to fill the gap, insulating two houses for the price of one. The practical problems then to be overcome are guttering, subfloor airvents if there are any, and damp bridging the DPM. I've heard that the last of these is greatly overrated as a risk in a location such as this where little rain reaches the ground. A 100mm flexible ventilation pipe, as might be used above a bathroom ceiling extractor could act as a conduit for air to the front/back of the building. And the flight of fancy for valley guttering would be to lay a 400mm roll of code5 lead on a plywood former, supporting it with a suitable fall on a sacrificial scaffold mounted on a row of jockey-wheels, with the whole heavy contraption run into place on levelled ground from the street with the aid of the village cricket team's help. Then wall up the gap between you and the neighbour, lobbing in a time capsule with photos of the fun, squirt in the foam and never see the scaffold or feel cold again. OR alternatively to keep the rain out: form a new ridge directly over the passageway, with new valleys a couple of feet up each of your and your neighbour's roofs where you've full access to do the leadwork. Oh! I see my spliff's gone out....well, the daydream was fun while it lasted ;-)

Ah well Andrew, I've crawled in and out of every corner of my house and I know pretty much what's what. I was expecting what you saw although the dirt falling out was pretty spectacular, I admit. Now above there the loft space was a totally sealed space with no way in. I had to knock bricks out of the end wall to get in from the main roof and then I found half-tree beams and plaster with everything lime washed. Very spooky crawling through there. I think the room below that bedroom is earlier and then the bedroom was built on later - hence the ledge stepping into the room. The floor in that bedroom was maybe 9inch lower until the 1990s when the previous owners had it raised because the guy was tall and kept banging his head on the low beams below. Hence I think that part of the house was originally a store with loft, but it is all more recent than the main part of the house because that back wall of the house is double brick. Cheers

Hey Brian thank you very much. After 180 videos and over half a million views you are only the 2nd person to give me a Superthanks. I never ask for thanks but occasionally it would be nice. Regards

[@CSquid100]

@@HaxbyShed Thanks again Paul. Was the insulation to current fire resistance standards? And did you need building regulation certification? Greetings from the Netherlands.

[@HaxbyShed]

@@CSquid100 you might think my reply a bit casual but all I can say it was new insulation designed for houses so to that extent it will be fire resistant. And also to say this is just one wall in my own home and I won't ever be claiming it on an Energy Performance Certificate or anything else for that matter ..... so I think that answers your second question 😉😉. Cheers

Good job! Those old walls are hard to deal with, i have done my share of dry lining Phil

[@howardosborne8647]

Me too,Phil. Having done a few barn conversions over the years you learn/invent a number of your own tailor made solutions for fixing and levelling insulation and plaster board to scabby old walls.

[@HaxbyShed]

Hi Phil, I think any surveyor would say knock it down and rebuild the wall but the fact is it's been there perhaps 150 years and is good for another 150 - since we don't have earthquakes in the UK. I think people over-worry about these things. There are always reasons to spend money if you want to. I watched your vid changing the top bearing on the Harrison vertical head. That will come in handy thanks. Cheers.

@@HaxbyShed i did completely strip that head and rebuild it because the sight glass was smashed and all the bits were inside! I don’t think I videoed it though, i will have a look! Phil

Great video Paul. I have used insulated backed plasterboard a couple of times now and got some great results with it but you are right it is much more expensive than buying the insulation and plasterboard separately so tempted to try it this way next time. Also from personal experience the insulated backed plasterboard is quite awkward to lift especially in full sheets (definitely a two person job). I suspect doing it this way does make it slightly easier if you're doing things on your own. I've used the dot and dab technique every time but might try just going for mechanical fixing next time (as you are meant to put fixings in anyway using the dot a dab technique for fire safety measures). I have used foam adhesive last time around and you have to be relatively quick to get the boards up and in place before the adhesive sets but it does go very solid and no flex/movement in boards once cured. Once again great video and very informative.

[@HaxbyShed]

Thank you Sam, if I was doing more, particularly on a small section, I would try 'dot and dab', many people have suggested that. I am sure it is more work to fix insulation and plasterboard separately but with low ceilings and limited space it makes the job a bit more manageable. But I imagine that fixing insulation-backed board with foam on a straight good plaster wall would be a doddle. Cheers

Fantastic video! I'm planning on doing something similar in my house this year. I had originally planned to use insulation-backed plasterboard, and I never thought to compare the price of that versus using separate insulation. This might even make the overall job easier! Subscribed - thanks!

[@HaxbyShed]

Hi Chris, that's high praise thank you. There is further advice coming through in the comments. Thanks for the sub, but only fair to point out that most of my videos are about my hobby machine shop so I hope I'm not 'mis representing' with this DiY vid. Although I've done a few DiY vids now. Cheers

[@mk1cortinatony395]

Thanks for this Paul, very timely as I am trying to make a block wall workshop a bit insulated. I may just attempt to stick celotex straight to the blocks. Must be better than nothing.

[@HaxbyShed]

Sounds good Mk1Tony, simple is best. Cheers

[@DribAllz]

good job Paul, plesant and informative viewinig

[@HaxbyShed]

I'm no expert John so it is just sharing, for what it is worth. Glad you enjoyed it. Cheers
