It's so great to see a professional insulation installation! I am in the middle of a DIY wall insulation project, so I am very curious how more experienced people do it. I am taking a very radical approach: I removed all plaster, internal walls, electrics and plumbing. That allows me to have a nearly uninterrupted layer of insulation. I attached 50mm PIR boards to the walls using adhesive to avoid cold bridging from screws, then put electrical wiring inside the insulation envelope and glued plasterboard onto it all. All partition walls, backboxes, plumbing etc are entirely contained inside, just thinning the insulation down to about half its thickness where the electrical boxes etc go. I used 25mm PIR inside the window reveals, on all four sides, again glued in, and glued MDF windowboards on top. That seemed to me the best I can do. It's probably not a commercially viable approach, but as a DIY project I do hope it will pay for itself in the end. 🙂

Did it work I am thinking of doing the same with 50mm then plasterboard rather than insulated plasterboard

For the flir camera, I prefer the rainbow effect as it shows the contrast between the warmest and coldest areas really well. Thanks for the video, appreciate seeing how you’ve done it and get some ideas. 50mm won’t work for me. I’ve got a couple of samples and I will be using 30mm for the walls and 50mm for the ceilings. I’m hoping it’ll be almost just as effective.

I have no experience in insulation and planing to insulate my single garage (Internal insulation - single brick wall). Have seen a lot of videos but it is not clear if: 1. I need to install battens or not 2. If battens need a special tape before screwing them to the wall to protect them from moisture. 3. If I need to apply a plastic sheet barrier behind battens and insulation panels 4. If insulation goes inside the battens frame or on top of it. 5. Do I need to leave a gap between the insulation panels and the brick wall for air movement 6. Depending on your answer for for point 4, I assume the plasterboard panels will go on top on the insulation panels and screwed to the battens ? Sorry, for so many questions but 98% of videos about garage insulation don't show or explain this and almost everyone is doing this in a different way. Thanks in advance for your comments and hope it helps other people like me.

@brianiswrong Жыл бұрын

We have literally just had this done in our sitting room, 1880 house, no cavity. The boards are expensive (25mm or 50mm) compared to normal plaster boards, but the difference in " feel" of the room (3 external walls) is totally different. We had 50mm on externall walls and 25mm on the internal wall were the doors in and out are (saves having to have thick peices of timber packing out the door frames).

Internally insulating the gable end wall of a early 1900s typical northern end terrace. Two layer brick with 50mm cavity. Unfortunately the cavity is hard to fill 25mm-75mm variation. Additionally one corner has an old exposed chimney breast - which will be later converted to a wood stove flue. So, should I for all intent & purpose treat this wall as a solid wall due to the cavity? Wall has been stripped down to brick and fully cleaned of plaster. Looking to first add a couple of waterproofing layers and fill in any mortar gaps. Then looking at 25mm x 50mm treated battens and 1200mm wide 40mm Kingspan/Ecothem. Any advice on the above and what to look out for? What are your thoughts on bead cavity wall insullation for hard to fill cavities? Thanks.

@billystar51 11 ай бұрын

Don’t fix the boards with dot & dab. It will create cold bridging spots (where the adhesive is). Fix with either low expansion foam or some other construction adhesive.

Interested to hear you experience on gains would you expect from 38mm thermal PIR internally, I've just done my whole house external facing walls with this and ceilings in each room, for the internal walls just foil backed board. All PIR walls were battened out for wiring. I have my own benchmark, had last room skimmed (all others done during summer) and ran a blow heater on lowest setting for two days and dehumidifier, room was paint ready in 2 days - no internal doors up, taped sheeting over frames to trap heat and moisture, got from 13c to 23c in 2 hours. After turning off the heat it was still 19c after 3 hours. I guess I may have answered my own question :) If your in a position to put this board up the saving on heating (oil / gas) is within a few years.

@SDRobertsPlastering Жыл бұрын

Assuming your property is built from 9" solid walls (average thermal resistance being around 0.8 - 0.9 m2k/w ) with a 37.5mm PIR board your thermal gains will be around 40% on the walls alone. The fact that you have also done the ceiling which typically draw around 25% heat (depending on existing insulation levels) and also lined the internal walls with foil backed board I'd imagine you'll be well into 50% improvements for this room. When installing PIR insulation my customers often tell me they can keep radiators on very low during winter and the rooms warm up rapidly and stay warm for a long time even after turning off heating

@Hew.Jarsol 8 ай бұрын

It just masks it?

@bobgriffin316 8 ай бұрын

@@Hew.Jarsol No it does not mask it. The mould does not happen when the wall is insulated. The reason is because the wall is warm because of the insulation. The mould only appears because of moist air hitting a cold surface. When the surface is warm the moisture does not drop out of the air and condense on the wall. The moisture stays in the air and does not cause any condensation and mould at all. An insulated wall gets to the root of the problem of mouldy walls. However, just cleaning the mould off the wall and painting over the wall does only mask the problem It will get mouldy again when the wall gets cold again the next time the outside temperature goes down again. The problem has not been fixed.

Hi there I live in a cold timber frame house in Ireland built in 2003 drafts under window sills and skirted boards. And draft coming up wall from esb and gas meters box Should I rip off plaster board and replace and find and plug all drafts or just put insulated plaster board over existing plaster board???? Any help please I’m a diy guy as no cash for professional to do job

@robinbennett5994 11 ай бұрын

I'd be tempted to rip off the plasterboard and fill the timber frame with rockwool. Then add a plastic membrane for air-tightness, and plasterboard over that (all of which should have been done by the builder!). At that point you don't really need insulated plasterboard, but it's not much extra work and it insulates the timber frame itself and prevents cold spots where condensation and mould can form.

Just finished installing the 12mm XPS/Jackoboard/elements board in our downstairs loo on 3 external walls and 20mm on concrete floor. This room was the coldest one in the whole house as it had 3 external wall, house is 1985 double skin and poorly insulated cavity wall. With certainty we can say it's now the warmest room in the house, radiator turned down to 2.5 and temp between 18.5-19.5 during recent frosty days. Any advice on that as I couldn't find anything about this method on KZbin. Will keep an eye on this room over the winter and probably do the same to the rest of the house. What's your thoughts on that?

@SDRobertsPlastering 11 ай бұрын

XPS is a good option even at 12mm you'll significantly improve the R values of the walls. Floor typically draws around 15% heat. Make sure to use a PU adhesive or AC50 adhesive when sealing joints (not drywall adhesive)

@SDRobertsPlastering 4 ай бұрын

@@HouseFairyDIY Yes I've also done many videos on the importance of insulating around window reveals. I mentioned sash windows because the only restriction is when chambers prevent me from stripping and insulating the reveals so in this case the face will be insulated and a thin profile insulation is used to cap the edge. If the sash window is new I'm assuming it operates on built in springs not weights so in theory the reveals can be insulated. All window reveals must be insulated properly and the gap between the frame and masonry fully sealed otherwise the reveal is at risk of cold bridging and this could lead to condensation/ mould developing around the reveals.

@SDRobertsPlastering 10 ай бұрын

It's a common question I'll be doing a video on this subject. In a nutshell air tightness is vital. But more importantly any penetrating damp issues MUST be resolved prior to install. In my experience this is the biggest cause of interstitial condensation and trapped moisture (trying to cover over problems with insulation) Walls must be water tight before considering IWI. So it's important to inspect mortar joints, render, gutters, downpipes and window seals.
