Hi
I'm in the middle of building a large man cave and am ready to order insulation.
The construction is as follows,
28mm loglap cladding,
2x1" batons,
Tyvek breathable barrier,
9mm osb3,
4x2" frame,
insulation, airgap,
100mm block,
dot dab plaster
The building is 11m x 5m and there is block pillars every 2.5m approx and has a flat (well sloping) roof, and it will be heated by 2x gas fired convector heaters (lpg)
My question is re insulation, I am looking at knauf dritherm 37 100mm for the walls, and 100 mm earthwool for the roof, as they are fairly cheap and i can get both for under £500
I have been trying to get my head around the u values and w/mk and kind of understand it, but I'm wondering is it really worth spending double what I'm planning for a better insulation, bearing in mind this is just a man cave and will only really be used on the weekend?
Will it make a massive difference to heat retention and would I ever get a payback?
Thanks
