Architectural membrane material (Chukoh SKY)
FGT Series
- Architectural membrane material (Chukoh SKY)
overview
The FGT series is made by impregnating glass fiber B yarn cloth with fluoroplastic PTFE and baking it. B yarn has properties such as a specific strength superior to steel, heat resistance at 700-800℃, and not being affected by low temperatures or ultraviolet rays. In addition to heat resistance and Weatherability, fluoroplastic has unique properties such as non-stick characteristics that does not allow things to stick to it, and water repellency.
Applications
Roofing materials
Ceiling materials
・Interior materials
Operating temperature limit
-60°C to +260°C

Features
non-flammability
fluoroplastic membrane material FGT series is a material that combines heat resistance glass cloth fiber and self-extinguishing PTFE.
For this reason, the FGT series is certified as a non-flammable material.
Self-cleaning
Dust and air pollutants that accumulate on the surface of fluoroplastic membrane materials are washed away with each rain, so there is no need for cleaning and the beauty of the material can be maintained for a long time.
Resilience
Generally, the smaller the diameter of the fiber, the higher the tensile strength per unit area. fluoroplastic material uses B yarn, the world's thinnest glass fiber, and is a membrane material with sufficient strength and high safety.
Sound absorption
The fluoroplastic membrane used as an interior material has moderate flexibility and air permeability, so when used as the inner membrane material in a double membrane structure, it can improve the acoustic effect inside a building.
Translucency
Natural light entering the building through fluoroplastic membrane becomes naturally diffused light, creating a soft space with fewer shadows.
Thermal properties
fluoroplastic membrane reflects most of the solar energy, reducing the heat transfer into the building. By using a double membrane structure with fluoroplastic membrane as an interior material, it is possible to improve the insulation effect.
Weatherability
It is not affected by ultraviolet rays or air pollution and maintains its functionality and safety as a roofing material for a long period of time.
