Saint-Gobain's translucent membranes for fabric roofs are made with a fiberglass fabric coated with Teflon (PTFE). The material is fireproof and has a longer useful life than a PVC-coated polyester fabric, although it is less flexible. PTFE's low adherence helps keep the membrane clean during a longer time. Two different products are offered:
—Sheerfill, a membrane for exterior uses, is available in various models with different tensile strengths ranging from 4555|5160 to 8500|7800 N/50 mm, and tear resistance ranging from 155|265 to 500|500 N. Weights are between 985 and 1540 g/m². It is suitable for covering both small architectural elements and very large spans (stadium roofs, transportation terminals, etc.). Depending on the model, translucence ranges between 9 and 16 %.
—Fabrasorb is also translucent (21 to 28 %) and is an acoustic absorber. Its use is restricted to interiors. Tensile strength: 1840|1575 to 3110|2500 N/50 mm; tear resistance, 75|85 to 130|95 N; weight, 280 to 475 g/m².
An optional photocatalytic finish of titanium dioxide with self-cleaning properties is available for both versions. Manufactured widths are 3657 or 3810 mm, depending on the model, and custom colors can be ordered, including metallic colors.

The initial cream color of teflon-coated membranes turns white after a period of exposure to sunlight.
For the reconstruction of the roof of the Metrodome in Minneapolis (USA), which collapsed in 2010, both Sheerfill I and Fabrasorb I membranes were used.
