PTFE coated fiberglass fabric (for tensile structures)
Saint Gobain Performance Plastics
SHEERFILL® is the trademark for a family of membranes used in permanent structures.
The composite is made of fiberglass and polytetrafluoroethylene (PTFE). SHEERFILL products 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. All SHEERFILL membranes conform to rigid fire and building codes for permanent buildings.
They can be coloured, on a project specific basis, also with metal effects.
SHEERFILL I is the strongest product, typically used for wide spans.
