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’ x 64’ rolls in multiple thicknesses as well as 4’ x 8’ sheets if more insulation is needed. Integrated edge taping system is offered to save over 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.
