Hi all,

I am wanting to insulate my front room. Suspended timber floor, with 100mm boards.

I'm trying to find the best place to order them from, alot of places only seem to have Kingspan TP10 which I understand is best for roof insulation?

I've not really found anywhere that does K3 Kooltherm or TFxx(can't remember the number) so have been looking at Polysterene boards instead...

I've tried B&Q,Minsters,Jewsons,Arnold Lavers...

B&Q i can get 4 boards (which is how many i need) for roughly 100 quid, just wondering if anyone knows anyone cheaper, or somewhere i can get floor specific boards for good price?

Cheers Mal
