    I've now insulated 4 rooms in my house - 3 using this method of fixing insulated plasterboard with adhesive bonding, and our bathroom where I mechanically fixed the plasterboard to battens. I find adhesive bonding a much easier method as with battens you need to pack out each batten to get it plumb and to line up, whereas with adhesive bonding, you can use the thickness of the dabs to adjust the finished position of the plasterboard.
    The ceiling in the spare room featured in today's video is lath and plaster - originally covered in wood chip wallpaper but recently stripped by us. The ceiling is well insulated in the loft space. The walls however are two course victorian brick with no cavities or insulation - in other words an open fridge in the winter. I'm gradually replacing the old windows with double glazing, but there's no point when the walls are so cold to the touch, so I stripped off the old plaster and render, and dot and dabbed them myself with Kingspan Kooltherm K118 thermally insulated plasterboard goo.gl/zCPCq1.

    Another brilliant video, thanks Charlie. The way you installed your insulation was so much more thorough than our builders! Re solid walls and dot & dab v mechanical fixing: On an early Victorian 4 storey terraced house, we were advised by Kingspan to mechanically fix on the 2nd floor where the walls are thinner and there was a risk of water penetration but I wanted to let others know that we got away with dot and dab on the 1st, ground and basement. The basement has no soil against it and the walls and floor were damp proofed with a Newton membrane. In addition, the walls get thicker as you go down the house so Kingspan calculated from our dims that they would not suffer from water ingress. We also observed the walls over a couple of years and knew that there was no damp issue. So it is always worth checking with the very helpful technical team at Kingspan.

    Charlie, tidy quality job. I've been plastering 40 years and I'd score you 9/10. Just a few comments, too much adhesive. Dabs only need to be 600 centres edge and middle of the board, dabs were too flat and should pretrude from wall 75-100 mm and board from window reveal out toward corner of the room All these tips will use less materials but all in all you have done a great job 👍

    • @CharlieDIYte
      @CharlieDIYte  Год назад +4

      You're welcome. With insulating internally like this, you need to pay close attention to cold bridging points (breaks in the insulation). Cutting through the board for plug sockets, where each sheet butts up to the next and around windows are the big culprits. Expanding foam adhesive is one answer rather than dot and dab adhesive but you have to choose an expanding foam that's compatible with the Plasterboard. It's well worth doing this but you have to get it right to prevent moisture from the house getting between the boards. 👍

    • @CharlieDIYte
      @CharlieDIYte  2 года назад +1

      Thanks George. Before you do it, do lots of research on cold bridging and make sure you buy a board with an in built vapour barrier. Sockets and the edge of each board, corners and around windows are potential sources of cold bridging (cold spots) where condensation can form. And check out this video ruclips.net/video/TIDb-pdOnXM/видео.html on keeping moisture levels down, though you may not have too much of a problem with that in Spain?

    Great video Charlie, it is something I really want to do and something I have researched a ton about, reading all the technical data etc but still feel there is not enough info out there. However this is by far the best video i have seen.
    I would love to pick your brain as you too appear to have done a ton of research.
    The main areas I have concerns with is the vapour barrier and access for wires without cutting or making holes in the insulation.
    So my thinking is to press the insulation against the wall (mines rendered and is sound), tape all the joins and foam/tape/seal all the edges. Then put 25x50mm (standard roofing type) battens against the insulation, 25mm thick and screw the battens through the insulation and into the wall. Then plasterboard (normals fine but i would choose foil backed) to the battens and skim.
    This way seems to allow for the best vapour barrier you can achieve and u would have a void for cables without compromising the insulation/vb, and you could hang selves, pictures etc to the wall as you would any plasterboard wall without messing with the insulation and vb, and from what I can tell buying insulation and plasterboard separately would be cheaper also. (Window reveals would have to be dealt with differently)
    Can you see any downsides to this approach other than losing a few mm due to battens being a bit thicker than dot&dab.
    You input would be very much appreciated.
    All the best

I'll probably go with the batten fitting solution as I doubt it has anything in the way of moisure prevention currently. Thanks again.

    • @CharlieDIYte
      @CharlieDIYte  2 года назад +1

      Good idea. The thing to remember when you do this is cold bridging, cold bridging, cold bridging. This is the biggest problem when insulating from inside. A lot of care needs to be taken with window reveals corners and plug socket boxes - which ideally need insulating behind to prevent cold spots and moisture ingress. Good luck 👍

It started to leaks in a few spots again, even after having all the clay tiles replaced a few months ago. I was able to get on the roof and sealed the leak spots but I'm not sure how long that will last. I don't mind running the heater in the winter more. I'll probably just stick to slapping some anti-mold paint up on these old walls and see if that does anything for me. Cheers!

    Had a mate that retro insulated 5 houses like this except he used PU foam adhesive to adhere it to the wall. And mechanic fixings afterwards. PU adhesive is less likely to draw water through the wall. But you can’t use it to plumb the wall.
    Great if your walls are fairly flat and plumb to start off with.

    What an excellent video really. Brilliant information very well made, you cleared up a lot of confusion for me.

    • @CharlieDIYte
      @CharlieDIYte  3 года назад +4

      Thanks Adam. Yes, I mechanically fixed the last room I did and going forward I think this is a preferable option. You're right to be concerned about condensation, particularly where you're cutting through the board for the electrical back boxes. You want to aspire to creating an impregnable vapour barrier and continuous insulation to eliminate any cold bridging - which is damn hard in reality. In the bedroom I've just done, I battened the wall with 2x1 tanelised, dpc between the batten and wall where it touches - as the wall isn't level there was a nice gap behind. Then I infilled with 1 inch Ecotherm, foil taped over the joins, and then mechanically fixed the Kingspan to the front. That way, the electrical boxes only penetrate through the front insulation (I foil taped a piece of 12mm ply to the back of the Kingspan at that point to screw the back box to), and there's no cold bridging. Oh and I used that expanding foam tape you might have seen in that vid, underneath the Kingspan. It's breathable but eliminates any cold bridging.

Fixing verticals with metal straps to reduce thermal conductivity - rather than timber to timber. Fill with fireproof insulation and screw fix 12.5mm plasterboard. Thickness 65mm internally. Wondering why you haven't gone for this approach, apart from the mechanics of getting it all aligned? with metal strapping, this has proven quite simple so far. Thank you R&T

    Just a note, only use KNAUF bonding compound on foil backed insulation board k118 otherwise you are taking a big risk. There's no point in pva-ing the back of the boards then, knauf bags are readily available from all drywall merchants. When taking delivery of your boards lay them down as flat as you can get them especially if its going to be days before they get used to avoid them bowing.

    • @darylheasman1
      @darylheasman1 10 месяцев назад

      @LB-gr5se I assume your asking why use knauf bonding compound specifically on the knauf foil backed k118. If you use BG bonding compound instead,you will certainly run the risk of the board coming away from the dabs once they had set as it is not designed to stick to foil. Where as knauf adhesive you will have no such problems.
      On normal wall board, BG,Knauf or Siniat bonding are all pretty much the same ,though I personally prefer BG bonding. With Knauf ,you have to pay a little bit more attention when mixing because it doesn't like being overmixed by drill and tends to thicken up quickly, which you don't necessarily want if you have a large mix to do. Hope that answers your question

      Before you carry out any work, make sure the house does not contain any asbestos. Also old houses with plaster walls would highly likely have no vapour barrier under the plaster to stop moist air from saturating the insulation. Back then, plaster walls were designed to allow the free exchange of air and moisture. If you're not sure if the plaster has been replaced with a vapour barrier or any insulation, remove a small area and check. You may just need foam or wool insulation and a vapour barrier underneath the plasterboards. I can highly recommend Tekwarm EPS HP, not sure if it's available where you live though.

      Fisher Duopower would do a good job. For the heavy stuff you could use wall anchors - probably 5x52mm. They work in insulated plasterboard as the umbrella forces itself open even in the insulated foam. The only downside is that the screw head on the bolt is reasonably large, or at any rate looks different to a screw. ruclips.net/video/e3hjzPNe5wk/видео.html

I made a frame of 50 x75 mm tanalised timber, screwed to the walls and filled with insulation. Then a polythene vapour barrier and then plasterboard. Keep the vapour barrier intact around power sockets was awkward. I’m still in the house and have had no issues. I have one last wall to insulate, the bathroom. It’s only a few m2. No external render.

    Hi Charlie, I’ve only just seen this video even though it’s almost a year old. I insulated the external walls in two bedrooms of my house the difference it makes is amazing. In one of the rooms I hacked of the plaster as it was very loose, but then I put a tight coat of sand and cement to get rid of some of the bows and bellies in the wall. Around the windows I framed them with 2x2 batterns. Before putting the boards up around I cut away the insulation only. When you put the board up around the window you can screw the edges around the window. Around the window you now have a reveal which you stick standard plaster board to using screws with a few dabs of adhesive. I’m about to move on to my bathroom. I just concerned about the condensation, and of course the tiles on that wall. Any advice

If you had seen the vast quantity of botches I have witnessed from both unknowledgeable amateurs and supposedly skilled tradesmen there is a case for more stringent application of the rules rather than less. The Building Regulations came out of the numerous local Public Health Acts that were brought together under a consolidating document, and without them we would still be victims of the Victorian slums.
      The Building Regs are continually evolving as they play catch-up with modern standards and innovation, the problem is that they are dealing in an ever more technological world so a becoming more prescriptive than performance based.

Now we are being turned into cash machines and it’s like Dick Turpin has written the building regs. Advanced they maybe, structured robbery it certainly is. All backed and influenced by Gypsum, Knauf, and all the rest. Replacing boilers at £2000 a pop, for something that’s going to break within 5 years. You don’t really get your money back! Electric consumer units seem to be changed more than underpants, that’s just making money out of people. Becoming an eco warrior has some merit, but it’s only forced and driven by the extortion of energy companies. Older property needs to breathe, and the funny thing is it’s already stood the test of time for there not to be an argument that it was built right in the first place. New builds I wouldn’t have given, and I could cry myself to sleep for the amount of ‘quality apartments ‘ I have inflicted onto the great British public. May the Lord have mercy on my soul.

      You're welcome. Just be careful with the plug sockets. Cutting the board does create a cold bridge. If you're going to dot and dab like I did and need to fit back boxes, rather than adhesive all round the socket, I'd get the back box ready, with a wall plug drilled in the wall to fix it in position, and then spray expanding foam in the gap behind the back box and quickly fix the box in place so the expanding foam expands and hardens around it. That will pretty much eliminate any cold spots that could cause condensation in this area.

We're always learning aren't we. Actually there are a few things I'd do differently since making this. On my most recent bedroom refurb to eliminate any potential cold bridging (sockets being a big source) I battened the wall with 2x1, infilled with 1 inch celotex PIR, foil taped over the battens and then screwed the K118 insulated plasterboard to the battens. Socket boxes were cut though the insulated board with a 12mm ply board foil taped to the back to screw the box to. That way there's no cold bridging though the socket. Also continuous insulation around the window reveals and breathable expanding foam tape under the insulated plasterboard. And I either didn't video it or I've lost all the footage 🤦🏻‍♂️ Thanks for the comment 👍
