Title: Cheap loft insulation at Homebase..
Post by CWatters on Jul 17^th, 2009, 8:05pm

Elsewhere someone pointed out that Homebase have an offer on Knauf Carbon zero Earthwool made with rockwool and recycled bottles. Around £5 a roll. Only 170mm thick so put in two layers. Not sure how long the offer price lasts.

Data can be found on their web site..

Thermal conductivity (eg U-Value for a 1 meter thickness) is given as around 0.044 W/mK.

Presumably this is sponsored by one of the energy suppliers.

I got some on offer at BnQ a few months back, like you say its the energy companies having to show some green credentials. Very cheap and I so gave my loft an extra layer.

When are they going to do an offer on Kingspan? My workshop needs more insulation before the summer ::) turns even colder

Spray Foam is the way to go with your workshop WS.
When I grow up I might buy myself the DIY spray foam kit.

Z it would cost about £500 to insulate the ceiling with 1" of foam, quick but expensive, unless I have the price wrong for 500 ft²

Jeez, if you tried insulating my barn the insulation industry would be working at maximum capacity.

Nothing wrong with a few draughts, is there Z?
