Teflon Coated Fiberglass (PTFE)
PTFE is used world wide as the preferred material for large-scale permanent tensile structures or structures requiring long life and with specific construction code compliance requirements. PTFE has excellent weather, temperature and chemical resistance in addition to its durability and strength. This tensile fabric roof material has a life span of over 25 years and is manufactured in accordance to standards such as ASTM E-108 and E-84. PTFE varies in translucency from 7% to 15% and reflects between 68%-75% of incident sunlight. The quality of light transmitted is color balanced, diffused and free of shadows and glare.
Before installation, PTFE has an irregular off white or slightly brown color, which is caused during the manufacturing and fabrication process. Once exposed to direct sunlight, the external surface of the membrane bleaches to a milky white within a matter of days.
PTFE is the obvious option if long life and low maintenance are the most important factors in selecting a fabric. This material requires heat-sealing at the seams to join fabric pattern sections and has a life span of over 30 years.
Other non combustible fabrics include silicone coated fiberglass and hybrid PTFE. These materials are more environmentally friendly, more pliable and available in colors and with higher translucency than standard PTFE.
