If only I had read this before spending £600 on 50mm Kingspan-----ah well
look on the bright side Ive got 100 square metres still to buy at half my
present price of £36 per 35mm board.

100mm thick in 8x4 slabs is 27-28 quid in B&Q (chester), 17-18 quid
for 50mm thick.


Is that really Celotex? I just get blank looks when asking for it in
any of the sheds.

B&Q chester have a big sign on the door, cheepest kingspan anywhere,
and they are right.
