Gripset BRW PFN is a self-adhesive butyl rubber sheet membrane designed for high-performance waterproofing applications over floor surfaces to internal and external areas. Featuring a high tack butyl rubber backing and front fabric lamination, the BRW PFN membrane offers outstanding waterproof properties and enhanced resistance to vibration, movement and flexing while supporting the direct application of toppings and tiled finishes. Gripset BRW PFN represents a true hybrid system, used in conjunction with, and complimenting Gripset liquid membranes to offer greater versatility and functionality over standalone liquid and sheet systems for critical and standard waterproofing applications.
