Reef Industries' Griffolyn® vapor barriers and vapor retarders can prevent water vapor from causing poor insulation performance, structural damage and other moisture-related problems. The main reason for retarding the transmission of water vapor through the building envelope is to prevent water vapor from condensing within the building structure cavities. The Griffolyn® polyethylene vapor retarder system's low permanence keeps moisture from infiltrating the building envelope.
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' x 200' (61 m x 61 m), greatly reducing in-field seams and the potential for failure.
Griffolyn® under slab vapor retarders and barriers prevent moisture from migrating into habitable space and causing problems such as deterioration of flooring adhesive, delamination, bacteria growth and warping. Even if new concrete is allowed to dry to the point where flooring can safely be installed, the absence or improper installation of a vapor retarder can later lead to expensive failures.
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.
Ventilated dirt crawl spaces provide a source of moisture that can lead to mold, mildew, fungus and even structural decay. A crawl space can foster environments that lead to severe health issues, environmental moisture problems and increased energy consumption. Therefore, a crawl space needs to be sealed with a crawl space vapor barrier or crawl space vapor retarder to help maintain humidity levels for occupant comfort, reduce heating and cooling costs and minimize other moisture-related problems.
Rainfall on freshly poured concrete pavement causes obvious problems and threatens to adversely impact the quality of the in place product. Protect newly poured concrete with Griffolyn® Type-55 rain protection covers. Griffolyn® products are internally reinforced laminates offering high strength and durable performance in demanding conditions. Type-55 is a 3-ply polyethylene laminate offering excellent tear and puncture resistance and is UV stabilized to provide superior weathering characteristics and service life.
Griffolyn® products are available in stock configurations for immediate availability or can be custom fabricated to the specific requirements of your project, including roll lengths up to 1,000' long for use with most paving equipment poly-roll attachments. When weather threatens, Griffolyn® Type-55 rain protection covers can protect your product and its quality. Specify Griffolyn® with confidence.
