PTFE – or Polytetrafluoroethylene – is a synthetic fluoropolymer (a «plastic» of sorts) that is used in a wide variety of applications, the most well-known being a non-stick coating for frying pans under the brand name Teflon. In addition to PTFE’s countless other uses based on its non-reactive nature and low coefficients of friction, it has established itself as a beautiful, versatile and durable coating for tensile architecture applications. PTFE is most often used to coat fiberglass fabrics on stadium roofs, canopies, atriums and in other designs that go beyond the realm of traditional building forms.
For the past ten years, PTFE-coated fabric has proven itself a unique, intriguing architectural material. But it has its flaws. For example, fiberglass blocks a significant amount of natural light.
And PTFE coating can become compromised when folded and flexed, while the fiberglass fibers underneath lose their waterproof properties or even break.
Enter the next generation of PTFE fabric: SEFAR Architecture TENARA Fabric. TENARA Fabric is not only coated with PTFE, but the yarns in the fabric itself are made of PTFE – the versatile polymer is inherent in the material. This unique combination of PTFE yarn coated with PTFE, technology exclusive to Sefar, allows double the light transmission of similar materials – 40% vs. the industry standard max of 20% - and allows Sefar’s 100% PTFE fabrics, like TENARA to far surpass traditional PTFE-coated fabrics in a number of other ways:
TENARA Fabric will flex and fold countless times without cracking or losing strength, significantly outlasting traditional PTFE-coated fabric. It offers the industry’s only 15-year warranty and an expected lifespan of 25+ years. The fabric is also easy to maintain and resistant to UV rays, acid rain, saltwater and other environmental challenges.
For permanent tensioned and especially retractable fabric membrane applications, TENARA Fabric is the premier product in its category. It has superior durability and pliability, is foldable and flexible, and does not become brittle over time.
TENARA Fabric’s remarkable light transmission cannot be overstated, as there is no product of its kind that comes close to evenly diffusing and transmitting up to 40% natural light, reducing the need for artificial light and ultimately making the spaces below it more comfortable and productive.
Unlike PTFE-coated fiberglass, which has a yellow-brownish hue when first installed, TENARA Fabric is pristine white at installation and throughout its lifespan.
The material is easy to clean and naturally resistant to stains, mold and mildew.
In addition to its cutting-edge look and design applications, SEFAR Architecture TENARA Fabric significantly outperforms and outlasts traditional PTFE-coated fabrics. The future of fabric architecture is SEFAR Architecture TENARA Fabric.
