The insulation in my loft was done before I bought my house back in 97. It's just plain open glass fiber that comes no higher than the top of the roof rafters. So that's probably about 4 inches
I would like to improve the situation, but I cannot have insulation higher than the rafters since, like a lot of people, I use the loft for storing loads of junk.
Is there any insulation that is more effective than ordinary glass fiber, thus requiring less head room. I have seen some glass fiber rolls in B&Q that are sealed in plastic with a foil layer. Would this be more effective?
Perhaps I should use Celotex to put insulation next to the tiles.
Any suggestions?
Thanks.
