Putting insulation in my shed. I have 100mm bearers in roof. I have a choice of 90mm bats or 145mm.
Would i get any benifit putting the 145mm bats in and compressing to fit instead of the 90mm ones?
I have read you will increase insulation benifit but not to full effect if compressed. Is this right?
145 compressed better then 90mm uncompressed but not as good as 145uncompressed.. :think:
