I'm unsure as it's under a tiled and oak floor that I don't want to pull up to investigate. All I know is the house is freezing and doesn't retain heat and I know from looking under the stairs and lifting some floorboards, there is just a hole under the house. I can't be sure whether they...

While the septics seem to successfully use it, the UK doesn't like it. https://commonslibrary.parliament.uk/spray-foam-insulation-and-mortgages/

Hi all, I've recently come to the conclusion, that my inherited wet underfloor heating is more than likely sat on cement boards, then floorboards which face the outdoor open suspended floor cavity. I still need to find a section to investigate and confirm, but I have a hunch that there is no...

I'm about to start insulating our external walls, internally. I plan to use the "warm batten" method. I.e. sticking PIR to the wall and then mechanically fixing battens through it. The walls I'm tackling first and back to brick, so far from straight/plumb/even, which is complicating matters. Do...

Rooms need 10 to 80 lumen per square foot, so my living room, 22 x 16 needs between 2 minimum to around 10 bulbs, as 50 watt down lights more like 16, this would be 800 watt, of which around 100 used for light, and not talking about fully heating the room with the lights, although that's what...

I'm not sure I'd bother if the insulated board is well fitted and sealed together, but it's little harm or cost, so it may help you sleep at night! I found that 2 parts spray foams work much better than expanding foams for joining PIR sheets -...

Can you get the kick panels off? I had gaps between floor boards and wall. Was very draughty. I reached in and sprayed expanding foam to fill the gaps. Messy stuff if you haven't used before. Have recently seen a similar post and there was a suggestion to stuff loft insulation under the...

Why thats its job, a can of spray foam seals insulation boards gaps, after all that's all foil backed insulation board is, a layer of spray foam between two bits of foil.....how else do you think its done...laser cutting of the board to fit...

That is why god invented spray foam...

Condensation will form only when warm moist air hits something cold. So insulate those spaces and fit a moisture control layer, or plastic sheeting as its known. 150mm Fiberglass blanket has a u value of 3.2 and ridge insulation can go as high as 8. So its a question of do you want to pull off...

If they've foamed over the underfloor air bricks, you're going to have problems in the future.

It's icynene spray foam and fully breathable. It was not done by this same builder but a well rated insulation company who gave a guarantee and assured me its fully breathable even over the ventilation bricks. So I was not particularly worried. It was dry as a bone under there but admittedly...

To insulate my loft space I was planning to put kingspan in between the rafters, 150mm rafters, 100mm-120mm kingspan with a gap above to let the membrane breathe. However kingspan is cut by hand, not very well, and it's not a good fit in many places. So I did a small area only and then stopped...

So our house is relatively well insulated overall. However my sons room (He is 2) is directly above the integral garage. As a result that room and that room only is always freezing, the integral garage is not insulated and doesent have any heating, the ceiling does have plasterboard on it BUT...

I am sure it's technically possible to spray-insulate a roof with foam in such a way that doesn't leave the timbers vulnerable to rot, but resulting increase in labour costs would mean that it would be not much more work to use PIR foam boards. You can save money by using seconds. Only you can...

You can’t use spray cans , would need hundreds for the volume required and ruin your property .

Good afternoon , we bought an old Edwardian house last December that doesnt hold the heat very well Last winter i spent a lot of time in the attic removing the old crappy pink insulation that was up there and replacing with about 300mm Knauf Eko Roll Loft insulation roll. I got about 50% of...

Going back to my wall lining, I was wondering about your 2nd suggestion being equally applicable to me? Instead of battening and then insulating between and having to put additional insulation on top - could I line the whole wall with PIR boards, batten on top and then affix plasterboard? There...

Hello all I'm handling the sale of my Mother in Law's 3 bed semi ex council house in West London. The buyer's surveyor has picked up that it has foam spray on insulation in the roof (done in 2004) and we need to have it removed and re inspected before the buyer can get their mortgage. As far...

Forgive me for stating the obvious but if you read my post you will understand that the goal is to insulate. This means to prevent heat loss. Rockwool is used for insulation. That means it stops heat loss. Heat will be lost upwards, downwards and to the sides. I have calculated that this hot...
