Griffolyn® Wall Vapor Retarders & Barriers
Griffolyn® wall vapor retarders effectively control air and vapor diffusion to reduce the amount of moisture infiltration into the building envelope. It is estimated that air leakage through a hole of less than one square inch can allow passage of up to nearly eight gallons of water into the building envelope over the course of a single heating season resulting in mold and decay problems.
Griffolyn’s® line of fire retardant vapor retarder materials pass NFPA 701 Large Scale "Standards Methods of Fire Tests for Flame-Retardant Textiles and Films." They have a Class 1 / Class A Flame Spread Rating per UBC-42 and ASTM E-84.
