There are a couple of companies selling cellotex/kingspan seconds on ebay. I have bought from the one based in Goole and the sheets are just as good as new sheets of insulation. They have obviously been left outside for a while and the foil is sometimes a bit dirty, but these sheets are always concealed. The price for 25mm celotex was less than half the price Wickes were selling for. I managed to get 14 8×4 sheets inside my estate car – cut the sheets into 8 x 2 and then cut a small piece of the end.

I am converting a barn myself and I am wondering which method of insulation to go for. When I initially tiled my barn roof I fitted cheap velux style windows, and whilst these are double glazed it seems to me that any heat that is retained by the insulation in the roof will be lost through these windows.
One could easily spend £40/square metre on insulation only to lose this heat through the roof windows. The best roof windows that I have found, the Fakro FTT Thermo Timber triple glazed roof window quotes,”Mid pane U value 0.5W/m2k, window U value 0.94W/m2k”, in the specification. 300mm of Rockwool is said to provide 0.40w/m2k, any ideas? The zero heat building seems a long way away!

I would not consider multi foil, such as Airtec Double Insulation or Thermawrap, you should check out this site before purchasing this kind of insulation
