Roof Vapor Retarders & Barriers
Made from durable and strong, internally reinforced polyethylene laminates, the Griffolyn® roof vapor retarder and barrier system withstands extreme temperatures and is highly resistant to punctures and tears. Griffolyn® roofing vapor retarders are available in stock sizes, which are available for immediate shipment and can be manufactured in sizes to meet project requirements up to 200’ × 200’ (61 m × 61 m), greatly reducing in-field seams and the potential for failure.
If building codes require a fire retardant vapor retarder, Reef Industries provides a line of fire-rated vapor retarder materials that 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.
