Insulated Plasterboard Makes It Easy!

[@naeemsarfraz9480]

Using the laser to mark the windows, genius! Great job

[@hartleyhubbard3827]

good job, brother.... I like your final comments about learning from your mistakes. A neat thing I like about watching DIY stuff on KZbin, is that commonly people will admit mistakes and how they learned from it (them), and what they "should've" done. Months ago, I shared a neat saying w/ my wife, wanting to impress her, "commonly, people learn from their mistakes. Wise people learn from the mistakes of others." She turned her head and after a moment says "and fools don't learn from either of them." Hartley (garden grove, CA)

[@markdyballuk]

i agree wholeheartedly with your comments about professionals Keith, when you get someone with pride in their work it makes a world of difference. Hope the insulation is holding up and you don't have any damp/condensation issues.

[@brunswicklord6365]

Completely agree with your view about getting experts in.

[@paulprescott7913]

Great vid Keith, loving the way you marked the window. Charlie is a top bloke and his channel is well worth a visit.

[@IrelandConstruction]

Hi Keith, I really enjoy your videos! But while I understand its important to learn from mistakes of the past, it is well documented that by not flank insulating the reveals of the windows will create a thermal bridge (cold bridge) causing up to 25% of heat loss. Secondly the Thermaline Plus is not a vapour barrier, but in fact its is a vapour control layer which is permeable. And thirdly, this is just a tip, often when I'm doing retrofits like this, rather than using mdf around the window reveals I'll use pvc facia board, which is non-conductive, clean and rot proof. regards Steve 🙂

[@joeyj6526]

The PVC fascia board is a great idea! I have some of this left over and this is a great use for it. Never would have thought to use it this way

[@Realmaven]

In these days every second claiming it is engineer, expert etc. But seeing how they do their job, I preffer to do it myself. Great video, thanks!

[@Smithb83]

Great job Keith, really liked how you used the laser to get around the windows perfectly 👌🏻

[@cobberpete1]

Great job Keith. Love the idea of using the Laser to mark out the cut outs. I will remember that for my next time.

[@northeastcorals]

I believe "Cold Bridging" is when cold moves along a temp conductive material that allows it to "bridge" areas of insulation, not a gap in the insulation that allows humid air to pass.

[@kevin-the-carrot]

I have a project of my own coming up that i will be using moisture resistant plasterboard,so it was interesting watching how you tackled it and the foam adhesive i thought was a different way rather than dot and dab.Your videos are very informative as a very keen diyer they help me with my projects.Keep up the good work.

[@RagnBoneBrown]

Thank you

[@cb379]

I would have used UPVC Fascia Boards on the window reveals .... Available from national plastis - Use Squirty foam insulation to stick in place and no no wicking up of moisture off the window frame either Available in white up to 415 deep and in woodgrain finishes too

[@andyc972]

Nice Job Keith, thanks for this, excellent summary at the end - as always honest and open - very refreshing in this day and age !

[@RagnBoneBrown]

Much appreciated

[@tonyworkswood]

That walls turned out brilliant, I've got a wall similar. I like the laser level for marking window cutouts on the new boards. That's a godsend for speed. I've never seen that trick before. I might eventually invest in one. Thaks for that. Tony

[@RagnBoneBrown]

Cheers Tony! 👍

[@bobafetting6373]

Love thermal board. Have used it in my lounge and little one’s bedroom. Makes a massive difference. Tiny thing. Gyproc - pronounced ‘Jiprock’. Like Gypsum (‘jipsum’)

[@oskarsmillers]

Good job ! Some mistake i noticed, as i know,correct way is first joint filler, mesh tape set in filler, and then again filler. and agree, prefer to use mesh type tape, much stronger as paper one👍

[@denisoriordan6739]

Brave… Brad nailing into 9mm MDF. Nice job. Great result. I hate the idea of dot’n’dab. It leaves an open void between the plasterboard & the block work, & I find the void draughts like a chimney. Your foam adhesive all around the board makes more sense, just join the beads of foam through the joints at top & bottom.

[@D_8KEN]

The benefits of dot and dab for levelling are a huge bonus. I had old walls that were 7cm out at the top which dot and dab saw to with ease. I don't like it, but it has it's uses.

[@pteddie6965]

Thanks for this video. I enjoy watching you problem solve the difficulties and mistakes that you make.

[@RagnBoneBrown]

Thanks for watching!

[@benjaqsonworkshop9974]

Thanks Keith for another real-world example of how doing something actually works. I've been thinking about using this insulated board but wasn't sure. This has given me the confidence to go ahead. I suspect you'll get some discolouration by the windows but unless they're open almost all the time you'd get it anyway no matter how well insulated. That might depend on whether you heat the room and ventilate/dehumidify it but nothing to worry about. Thanks again.

[@TheWhale45]

Use the stuff with the aluminum vapor barrier.

[@frankling9840]

Don't use this method will have issues with interstitial condensation within 12mths, as above you need to use rigid insulation boards with a separate foil back plasterboard... this board he uses is for overloading where you have a ventilation pathway behind.

[@core-element]

Ok job for that type of room, I foam all my boards on, once you have to take one off you find out just how well it adheres. I thought that about the reveals and then you mentioned it at the end. I use thermal tile backer board now on all door and window reveals, for it's insulation a moisture resistance qualities plus thinner boards available for tighter frame spaces, does need a skim over tho! Thanks for the video.

[@subhumanrogueminiaturesfor2538]

Do you know if that's a suitable option when looking to insulate a single skin 100+yr old outbuilding that pretty sure is getting some penetrating damp, has a tin roof. Thinking of adding somthing like stormdry to the outside but really struggling find accurate/consistent info in to fix directly or mount away with an air jap, with membrane or on and on inside insulation or wall side. Any tips atall or points to good guides very very much appreciated 😊 thanks

[@ivankoot2912]

Fantastic tip with the window. You deserve a like

[@RagnBoneBrown]

[@anwolfs9804]

Right on! Try to fix it yourself first, then if it doesn't work call in a professional for advice, try again. If it still doesn't work, let the professional do it. (Unless it's to dangerous to try it yourself ie heating or the more difficult Electricity installing...) Hope it stays this nice in there!

[@darrenwardell3079]

Absolutely brilliant video, really informative many thanks👍

[@geoffreycoan]

Good job Keith, approached clearly and metholodically. The window surrounds have more than a passing resemblance to the ones you built in that van conversion! Only thing I would have done differently is to but the two large sheets of plasterboard side by side and the infill at the side. Just makes it easier to butt the two boards together as you know the joint will be straight whereas infilling with the offcuts in the middle its more tricky to cut as the walls are almost never parallel. I too love Easyfill but its not cheap stuff. No nonsense filler you used as topcoat, what was that like for sanding Keith? That’s the one big advantage of Easyfill, its dead easy to sand to a flat finish. Another thing you can use as filler believe it or not is tile adhesive, it too sands easily !

[@RagnBoneBrown]

Cheers! The no nonsense stuff sands just as easily, I don't think I'd spend the extra on easifill going forward! 👍

Is the anything/guides you (or anyone else happening to read this) could point me towards please. Thanks

[@davep5829]

Great video as always, but your explanation of cold bridging wasn’t quite right. The issue you described is actually interstitial condensation, whereas cold bridging is where you have a component forming a bridge between the ‘warm’ and ‘cold’ sides of the wall build up - common examples would be steel beams, cavity wall ties, balcony slabs etc.

[@RagnBoneBrown]

Thanks for the info!

[@RagnBoneBrown]

Makes sense

[@riboid]

Yeh, I was about to mention that too, but hate saying anything negative about these videos as overall, it's a superb job. I have just done a massive extension in the UK and to give you a good example of thermal blocks; on all of my load-bearing walls (which obviously project down into the basement foundations), at the floor level in the ground floor, I removed x3 bricks at a time and slotted in a Marmox thermal block product, which is 600mm long and 100mm wide. It is load-bearing and literally prevents the cold from bridging up through the cold basement and up into my living spaces. Ask me if it was a nightmare of a job! For obvious reasons, you could only take out 3 bricks at a time and then slot it in, but again - absolutely hellish job, but all done now (My heating hasn't been on for over one year!) (Glasgow, UK).

[@konraddobson]

So how do you prevent mould from forming between the wall and the insulation?

[@silentscribes]

Well done!

[@svenwhothehell5980]

Good vid, can this thermal board be added over cavity wall? The cavity wall I have is next to useless against a west facing exposed wall. The inside of wall always feels cold and gets condensation in areas

[@QODQDJQ3232]

Your woodworking skills are very good, if paired with the Kunlun teeth that do not burst the edge, it would be even better

[@BischBaschBosch]

Don't think your window boxes should cause too much an issue un-insulated bud. Doing a good job I reckon so far. Give where you had the damp, getting the outside sorted will seal the deal. Your outside path being slightly above floor level, I'd probably sink some plastic channel along the perimeter bedded in pea gravel. Should better whisk rainfall away.👍

[@RagnBoneBrown]

Thanks mate, can you explain what you mean by plastic channel? I was going to simply excavate and then leave a good 100mm (150mm if poss!) below dpc with gravel beneath, which is what we have elsewhere on the bungalow... But intrigued by the idea!

[@BischBaschBosch]

@@RagnBoneBrown There's no one real name for it bud but if you Google search plastic channel drain/drainage you'll see what I mean. It's just ground level guttering for house perimeters. Should mean you can keep the existing path level flush to the wall and channel the water away still - rather than having a trench.

[@northeastcorals]

Ideally you need to look into Relative Humidly, once you understand that everything makes sense. If that room is completely unheated with large vents to outside then unfortunately the RH of outdoor air in winter at temps of 0 to 6 degrees is often 80% to 90% so this means your room will be too humid no matter how much you insulate the walls. However if this room was warmer than the outdoor temp this would have a positive affect on the RH. As I say RH is the key.

As a DIY'er pretty nice job, like you said, it's for you and your "learning curve" of various jobs, everybody makes mistakes, at least it's your risk not for someone who pay for that. I can only worried of not priming MDF from backside, might be less resistant to water - condensation, around window frame, than plasterboard in long run,. If MDF it swell, it stay like this, plasterboard is more breathable. Everything depends of ventilation of your workshop and how much sweat you put there :D

You want the struff with the aluminum vapor barrier because it actually reflects the heat back into the room or outside in hot areas. They took it off because Aluminum isn't cheap. You can't buy those boards in the USA. I'm starting to wonder why.

[@kevocos]

Well presented video mate. Installing Internal wall insulation (IWI) on solid wall type construction is fraught with the risk of creating interstitial condensation. I believe insulated plasterboard adhered to the walls without any ventilation of the created cavity space behind the board (which in this situation is impossible to ventilate anyway) is a poor design to use in this instance and in theory it sets up a prime condition for interstitial condensation. Fair play to you for highlight this and regardless of the theory it will be interesting to see how it performs for you in practice, which is where it matter.
