PTFE Membrane Roof

PTFE Architecture Membrane is made by coating a non-chemically reactive PTFE resin on an ultrafine glass fiber cloth. PTFE Membrane structure is a brand new form of building structure. The surface can be constructed by the architect. The design needs to be arbitrarily changed. Combined with the whole sunlight, the interior of the building covered by the film is filled with natural diffused light, and the contrasting surface is not strong. The difference in shadows makes the indoor visual environment open and harmonious. At night, the lights in the building illuminate the night sky through the film of the roof, and the shape of the building shows a dreamlike effect.

Features of PTFE Membrane Roof:

• The biggest characteristic of PTFE membrane is high strength, the tensile strength of PTFE membrane reaches the level of steel; and the lower modulus of elasticity is beneficial to the complex surface shape of the membrane;
• Wide temperature range, can be used in the temperature range of -70 °C ~ 230 °C;
• It has unique optical properties, and the incident light becomes natural warm light during the day, preventing glare, no shadow, and even light distribution; almost no ultraviolet light is transmitted, preventing the fading of interior decoration materials and equipment; night high reflection performance makes the room It has excellent lighting effect, reduces power consumption, and can bring out the brilliance of buildings in the night sky;
• Self-cleaning is good, rainwater can wash away the attachments on the surface;
• Having high light transmittance, a light transmittance of 13%, a thermal energy reflectance of 73%, and a small heat absorption amount;
• The service life is more than 25 years.

Application of PTFE Membrane Roof:

It is precisely because of the invention of this inter-generational membrane material that the membrane structure has become a modern permanent building. Widely used in large public facilities: the roof system of stadiums, airport halls, exhibition centers, platforms, bathrooms, etc.

Description of WELLFLON® PTFE Membrane Roof:

• WELLFLON® PTFE permanent architecture membrane is a kind of compound material formed by painting PTFE resin on fiberglass
  cloth(β fiberglass), this type PTFE glass cloth with our own unique technology.
• β fiberglass not only has higher intensity than steel,superior heat resistance(700~800℃),but also un-affected by low temperature and ultraviolet.
• Meanwhile,PTFE resin owns the water,weather and heat resistance as well as the unique self-cleaning performance and other unique properties.
• WELLFLON® PTFE permanent architecture membrane is the excellent construction material providing the superior properties and aesthetic exterior with longer using life.
