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.
