Griffolyn - 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.
