wanna see my snake?
I've realised I shall probably have a few questions over the next few weeks on these topics, so thought it best to make a single thread rather than keep using the pond one. Obviously anyone else with similar questions stick them in here.
Right, first question. I need to insulate a shed roof, the shed is about 20' by 8' and has single glazing down one side. I realise that I will never get the place particularily warm, but insulating the roof will help. I have access to rolls of 100mm or 170mm rockwool, or can buy the polystyrene sheets. I'm not sure, but I suspect the beams are only 50mm deep therefore probably discounting the rockwool.
With the poly board, there appears to be 2 types of cheap ones:
Universal 1200 x 450
Flooring 2400 x 1200
Both of these are 25mm thick, but the flooring one is 3 times the price and 6 times the surface area. Can the flooring one be used in a roof? If so, why is it called flooring? Any better ideas on what to use? Being inherently lazy I may just see which requires less cutting and get that.
