SHEERFILL® Architectural Membranes are used as permanent tensioned membrane structures in the sports, transportation, retail and specialty markets. These composite materials are made of fiberglass and polytetrafluoroethylene (PTFE). SHEERFILL membranes are available in a range of strengths and light transmission levels, providing the user with a choice of membranes to cover virtually any size structure from a full-sized stadium to a relatively small skylight.
The ORIGINAL PERMANENT Architectural Membrane, SHEERFILL I has proven itself as the strongest, longest-lasting architectural membrane material on the planet. Installed in 1973 at the University of La Verne in California, the original membrane is still in service and shows no signs of need for replacement.
SHEERFILL I (with EverClean) Data Sheets: ASTM/DIN
With a nearly ideal balance of strength and light transmission,SHEERFILL II has become the workhorse of the industry, providing exceptional life and value while allowing for long, column-free spans and dramatic designs.

By increasing the amount of natural light entering a space, and thus decreasing the need for daylighting, SHEERFILL IIA further enables improvement in the comfort of a building’s occupants, while maintaining the reliability and strength demanded even in the most challenging conditions.

Proven Long-Term Durability
In contrast to traditional roofing materials that would require frequent replacement, tests prove that SHEERFILL® Architectural Membranes provide up to 25 years or more of reliable service. There is no relaxation of the re-tensioned membrane from its original shape, even after years of withstanding high live loads, such as heavy snows and high winds. This keeps maintenance costs low, not requiring retensioning of the membrane.
High Energy Efficiency
SHEERFILL membrane transmits up to 20% of daylight without the heat gain of traditional glazings. Shaded areas remain bright, yet cool, even on the hottest days. HVAC costs are lower compared to other glazing alternatives, because SHEERFILL minimizes the need for heat dissipation. Reduced lighting requirements during the day also result in a substantial reduction in energy costs.
The SHEERFILL membrane is a translucent, noncombustible composite made with fiberglass and Teflon®. It has a Class A rating, and an overall performance in regard to permanent building codes, including fire codes. Noncombustible properties are inherent in these materials that do not degrade over time.
Stain Resistant for Enduring Beauty
The translucent characteristics and visual appeal of SHEERFILL membranes are unaffected by age, climate, pollutants or discoloration. Its impervious Teflon coating makes SHEERFILL highly resistant to staining. SHEERFILL membrane repels airborne particulates and chemicals that adhere to other materials. The natural action of rain keeps the surface clean and white.
Outdoor Lighting, Indoor Comfort
SHEERFILL® Architectural Membranes enable the construction of buildings with a stunning architectural profile, but the true beauty lies in the membrane’s superior ability to transmit light. SHEERFILL® brings the open, airy feeling of color-correct light indoors, filling even large sports complexes and industrial facilities with the diffuse, natural daylight, while the backlit luminosity at night creates a unique and dramatic architectural signature on the skyline.
Greater Versatility & Building Utility
SHEERFILL® meets fire code requirements for virtually all types of construction, and remains unchanged in temperatures ranging from -100°F to +450°F. SHEERFILL® membrane offers architects new flexibility in design. A variety of panel shapes can be combined into endless geometric configurations, allowing architects to address complex aesthetic and functional challenges while creating buildings of stunning beauty and excitement.
