insulation

Hi, I am building a shed and would like it insulated so that I can heat it for bringing on plants. What size insulation do people normally use in a 3x2 CLS stud (ie 63mm gap). Can I squeeze 75mm in there or will I end up pushing the internal panelling away? Thanks, Ed.

Hi all, I'm in the process of replacing & upgrading the insulation in the loft. It's an older (~1950's) house, with 400 centre joists that are ~100 deep. So the base layer (100mm) insulation fits nicely between the joists. I'm using 170mm topup layer insulation (mostly because we got a load...

We're planning to do a garage conversion of our integrated garage. The garage floor level is exactly the same level as the rest of the downstairs (hallway and kitchen). This seems to have confused a few builders who said they would have expected it to be lower. Given it is the same level, I'm...

I've got a 1950's cavity wall that has been injected with loose insulation. Unfortunately it's still quite cold so I want to add some 25mm kingspan to the interior walls. If I were to dot and dab the insulation board, do I need to be concerned about damp/structural issues? It's for a...
