There is sadly quite a lot of misinformation on this thread, and I've seen people on YouTube recently believe what's been written. To clarify, there absolutely IS a need to leave a gap between the top of your insulation and the underside of the boards. The British Board of Agrement (the BBA -...

Squashing 200mm into 180mm is going to be minor, especially as you're adding extra on top anyway! I wouldn't worry about it. Instead of using cross battening, I prefer using one of the newer ways on the market, eg Loftzone Storefloor or Loft Stilts. Both much faster and lighter (important if...

Here is a good guide to insulation values. Polystyrene is on page 5. You can see it has roughly the same insulation value as mineral wool. http://tinyurl.com/8hjtcmu The lower the k value, the better (it's the thermal conductivity). Expanded polysytrene is about 0.038. (Not 0.38, that would...

Perry525, thanks for taking the time and trouble to write your post. But Tony1851 is right, expanded polysytrene is about the same as mineral wool in insulation terms. So I'd need about 270mm of it, just like mineral or rock wool. And mineral or rock wool is much cheaper. (Which is probably why...
