NOFP is able to roll EPS up to 1 1/4” thick. Its barrier line is an ideal insulator and vapor barrier for radiant floor applications. It’s flexible, durable and walkable. Printed vapor barrier film includes 3” overlapped seaming flange in addition to tubing layout marks. It also accepts staples for secure retention of tubing. It offers 4’ by 64’ rolls in multiple thicknesses as well as 4’ by 8’ sheets if more insulation is needed. An integrated edge taping system is offered to save more than 40% of reduced taped seams and additional vapor barrier costs. It’s made of 100% expanded polystyrene foam protecting radiant floor installation from heat loss and moisture in addition to meeting most local building insulation codes without the use of reflective bubble.
