PTFE is a high quality woven fibreglass membrane coated in Teflon (Polytetrafluoroethylene), and is an ideal fabric for tensile membrane structures. PTFE fabric is high quality, weather, fire and UV resistant, and extremely durable. The Teflon coating creates a smooth surface that allows the fabric to be ‘washed’ by the rain, reducing the need for frequent cleaning. The membrane behaves elastically under normal conditions, does not creep or stress relax, and has a life expectancy exceeding 30 years. A standard PTFE warranty ranges from 12-15 years.
PTFE is highly reflective, making it ideal for shade structures, as it can withstand high temperatures (-73°C – 232°C) without transferring much heat. This is the defining feature of PTFE that differentiates it from conventional glazing. Testing has indicated that up to 80% of solar energy is reflected, with an 8% rate of absorption by the fabric itself. Some grades of PTFE however, can absorb up to 14% of solar energy, allowing a 12% rate of transmission through the fabric.
PTFE can be spot-welded, or sewn which creates excellent fabric strength, and removes the concern of creases and splitting as a result of repeated folding and flexing of the material by improving durability.
Lighting
PTFE fabric is a game-changer for indoor environments, thanks to its unique light-diffusing properties. By spreading natural light evenly, it reduces the need for artificial lighting during the day.
This not only cuts down on energy costs but also fosters a thriving environment for indoor plants and greenery. With PTFE fabric, your indoor space can benefit from optimal lighting conditions, enhancing the overall ambiance. This innovative material helps to create a more sustainable and aesthetically pleasing space, making it a smart choice for eco-conscious design.
Sound Absorption
PTFE’s air permeability and flexibility contribute significantly to its sound absorption capabilities. It effectively isolates external noise, helping to meet specific noise criteria for different buildings. The level of reverberation is closely tied to the internal dimensions of a structure, meaning smaller rooms benefit greatly from improved acoustics.
Additionally, PTFE can be used to manage sound in larger spaces, such as stadiums and aquatic centres, ensuring optimal acoustic performance in both small and expansive environments.
Maintenance
PTFE fabric combines low maintenance with exceptional quality, durability, and a long lifespan. Its resistance to UV light ensures the fabric maintains a bright and clean appearance over time. The Teflon coating imparts self-cleaning properties, allowing the fabric to repel moisture and stay pristine after installation. This unique coating keeps the fabric looking new with minimal effort.
Overall, PTFE is an ideal choice for those seeing a high-performance material that remains both functional and visually appealing with little upkeep.
