Protecting Large Spaces with Incombustible Strength: Nittobo’s Glass Cloth for Membrane Structures
A tough membrane built to withstand harsh environments. The heat and fire resistance of glass cloth supports safe, expansive spaces filled with a sense of openness.
Nittobo’s "Tent Membrane Materials" are high-performance architectural membranes composed of high-strength glass cloth coated with fluoropolymer (PTFE) or PVC resins. Their greatest strength lies in overwhelming heat and fire resistance, derived from the use of inherently incombustible glass fibers. In the event of a fire, the material resists the spread of flames, significantly contributing to the safety of public facilities and large-scale warehouses. Thanks to the resin coating, these materials combine excellent mechanical strength with weather resistance, maintaining performance and aesthetics over long periods even in outdoor environments exposed to wind, rain, and UV rays. The dimensional stability unique to glass cloth enables bold, sag-free designs for large dome structures and tent warehouses. Furthermore, designs can leverage light translucency to bring natural light indoors during the day, reducing lighting energy consumption while creating bright, open spaces. From industrial use to sports facilities, these advanced membrane materials expand the possibilities of modern architecture.
