Premium Performance
Platinum System begins with our Np3 waterproofing membrane. This is a non-asphalt polymer with solvents added for sprayability that cures to a 100% polymer membrane. Dow PERIMATE drainage & insulation board is applied to the Np3 self-adhesive surface. Platinum System comes with 20 year warranty protection.

PERIMATE board can handle up to 363 gallons of water/hr/2' x 8' sheet, with a warranted long-term R-value.
