PTFE fiberglass membranes can be installed in climates ranging from the frigid Arctic to scorching desert heat with an expected project life exceeding 30 years. PTFE Fiberglass coating is chemically inert, capable of withstanding temperatures from – 100F to +450F. The Low-surface free energy of the material creates a surface that is readily cleaned by rainwater. It is also completely immune to UV degradation. This unique combination of inertness, thermal stability, and surface properties make Birdair’s PTFE-Coated fabric membrane ideal for the project requiring superior weather and fire resistance.
PTFE Fiberglass structure has been constructed around the world with the acceptance by UAE, British, French, Italian, Japanese, and German National Standards as well as guidelines set by the American Society for Testing and Materials (ASTM). PTFE Fiber Glass membranes can be installed in climates ranging from grid arctic to scorching desert heat with an expected project life exceeding 30 years.
During Scientific tests of its solar properties, it was discovered that PTFE Fiberglass membranes reflect as much as 73% of the Sun’s Energy while holding just even percent on its exterior surface. PTFE fiberglass is additionally Energy Star and Cool Roof Rating Council certified.
Certain Grades of PTFE fiberglass can absorb 14% of the sun’s energy while allowing 13% of natural daylight and 7% of re-radiated energy to transmit through. PTFE’s Fiberglass yarns maintain an ultimate tensile strength of 500,000 PSI and a modulus of elasticity of 10.5 x 106 PSI compared to steel which offers 40,000 PSI and 29 x 106 PSI respectively.
Under normal conditions, the fabric behaves elastically and does not undergo significant stress relaxation on creep. The Woven fiberglass gives the PTFE fiberglass membrane with maximum flexibility. The fibers are drawn from hot melt glass through platinum dies into continuous filaments and are then twisted and pied into yarn bundles. The yarns are woven into a wide structure are woven into a wide structural fabric which is then coated with PTFE fiberglass to complete the process.
TiO2-coated PTFE is a type of fiberglass that is safe and fire-resistant. It has a layer of titanium dioxide (TiO2) that helps clean the air by breaking down pollutants and odors. This material is popular with designers and architects in Asia and is now gaining attention in North America.
The TiO2 coating is self-cleaning. It uses sunlight, oxygen, and moisture to turn pollutants into harmless gases, making cleaning and maintenance easier. Rain can wash away any leftover residue.
TiO2-coated PTFE is an eco-friendly and modern material, ideal for various structures and roofing systems. It is available in different grades, depending on how much light needs to pass through. It works well in cities and industrial areas where air pollution, like nitrogen and sulfur oxides, is a problem
When designing structures, acoustics play a key role in controlling noise and ensuring sound quality. Both external noise prevention and internal sound management are important to avoid echo and vibration.
Key Points:
Noise Control: Prevent outside noise from entering and manage internal sound for a balanced environment.
Sound Absorption: Use acoustical materials to absorb sound and improve clarity, especially where communication is critical. Solid materials alone are not enough.
Large Spaces: Arenas, maritime centers, and stadiums need special acoustical solutions. Noise Criteria (NC) levels, such as NC-20 for quiet halls and NC-50 for sports facilities, guide acceptable noise levels.
PTFE-Coated Membranes: These membranes effectively reduce noise and improve sound quality, making them ideal for demanding environments.
