B&Q Supplemental Loft Insulation

BraileTrail · 2010-01-24T09:57:33+00:00

Hi,Both B&Q and Homebaseare selling rolls of "supplemental loft insulation" in my local stores with a 2 for the price of one offer. Would anyone car to comment on the quality of this insulation?My loft currently has 100 mm insulation between the joists and I was thinking of laying some of this stuff at 90 degrees to the joists on top of the existing stuff. Would I be better taking the old insulation up and starting from scratch?Thanks,BraileTrail

if there is a damp room uderneath like a bathroom then i think it

*would* be a problem, there would be condensation in the insulation at a dew point, which would make it less insulatey, and rot timbers.

How good is a vapour barrier paint if applied to the celing of the room underneath?

The message from "george [dicegeorge]" contains these words:

Not perfect, but not too bad, actually, as long as it's a couple of coats of oil paint.
