Hi,
I’m looking at insulating my mother’s house myself and trying to work out the best option of attic roll insulation:
I’m looking at Rockwool (200mm thick and 1200 wide. 3.3 sq metre per roll. U value 0.44) and earthwool (200mm, 1200 mm wide, 5.97 U value?) as products to use but i’m confused as how to compare these products e.g.
Is 200mm of rockwool equivalent to 200mm of earthwool?
What’s the best approach to work out what product is best and what thickness i require of each.
Existing insulation has been removed.
Thanks,
Johnny
