Having just had to buy loads of foil faced PIR foam, one thing worth
doing is shopping around. I saved over 1500 quid on the price of celotex
as quoted by a builders merchant! It is still not cheap (about 12 quid
for a 8x4 50mm sheet) but a factor of two to three times variation in
price between suppliers is not uncommon it seems.
