S and B Crios System Board

EPS Underfloor Heating

Product Information

S and B EPS Crios system boards have been specially designed to assist in the laying of underfloor heating systems. It is a combination of an EPS board bonded to a coated split woven membrane that is blue in colour with a 50mm grid pattern to allow straight runs to be simply achieved and as with all other S and B EPS products it is both CFC and HCFC free. Standard sizes of S and B EPS Crios system boards are 2.4 x 1.2m with a 50mm film overhang on two of the sides allowing taping to form a continuous seamless surface with standard thickness being from 20mm to 140mm with other thicknesses available on request.

Advantages

Can accept all screeds
50mm printed gridlines for ease of pipe alignment
2.4m x 1.2m for speed of laying
50mm overhang on two sides allowing ease of taping joint
Woven membrane prevents clips from pulling
Bespoke thickness from 20mm – 140mm
Excellent price performance ratio
Green guide A+ rating
