Combines Griffolyn® reinforced high density polyethylene with a non-woven geotextile for an under slab vapor retarder with superior puncture resistance.
Griffolyn® Type-65 Geotextile
Reinforced high density 3 ply.
General purpose that meets the strength and permeance requirements of most applications.
Natural soil capillarity can allow large volumes of moisture to contact the underside of a slab. Properly formed capillary breaks within the soil foundation system, combined with a high performance vapor retarder, are the first lines of defense. Without an under slab vapor retarder, moisture can be forced upwards under pressure into habitable space. Mineral salts from the ground and from the concrete itself can be transported through the slab to the underside of the flooring system causing visible efflorescence and staining.
Reinforced fire retardant 5 ply. Delivers extra strength and extra low permeance for applications with extreme temperature variations.
Griffolyn® Type-90 FR
Reinforced fire retardant 3 ply. Offer greater strength and lower permeance. Qualifies as Class A building product for a higher level of integrity in walls, ceilings and roof assemblies.
Griffolyn® TX-1200 FR
Reinforced fire retardant 3 ply. General purpose vapor retarder for use in walls, ceilings and roof assemblies.
Griffolyn® Type-55 FR
Moisture is introduced into walls through both air leaks (convection) and vapor diffusion. Of these two methods, air leaks present a greater potential for causing moisture damage. 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. A high quality vapor retarder might be able to eliminate condensation caused by diffusion, but even an excellent vapor retarder is of little use if it can be bypassed by convective currents.
Some buildings generate large amounts of moisture as a result of activities or processes they contain. Examples include natatoriums, manufacturing facilities, certain industrial processes and food plants.
As a result of condensation which can occur within the roof assembly, these buildings may experience problems with saturated insulation, structural corrosion, staining, mildew growth, and other moisture-related problems.
Reinforced 3 ply. Combines 2 layers of U.V. stabilized coextruded polyethylene and a high strength cord grid.

Crawl space applications
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 vapor retarder to help maintain humidity levels for occupant comfort, reduce heating and cooling costs and minimize other moisture related problems.

how to install a vapor retarder
The Louise M. Davies Symphony Hall in San Francisco opened in 1980 and renovated in 1992.
A few years ago, the San Francisco Public Utilities Commission (SFPUC) determined that installing a photovoltaic (PV) solar system the building would benefit the people of San Francisco.
The SFPUC retained engineering consultant AEPC of San Ramon, Calif., to design the PV solar system for the 25,000-square-foot roof.
