Evolving architectural possibilities—A lightweight, highly transparent waterproof design roof made possible by ETFE film. We will lead a new era of architectural expression.

ETFE film is a new material that is revolutionizing the next generation of architectural design due to its excellent physical properties. It has been used in major architectural projects around the world, including the Eden Project in the UK and the Allianz Arena for the World Cup in Germany, demonstrating its potential as an alternative material to glass. Its ultra-light weight and high transparency reduce the load on the building frame and allow more natural light to enter, reducing both environmental impact and improving livability.

Features
Ultra-lightweight: Weighing only 440g/m², it contributes to reducing the load on the building frame and improving earthquake resistance.
High transparency: Visible light transmittance is extremely high at 90.8%, allowing plenty of natural light to enter the room.
High durability and stain resistance: Excellent weather resistance and chemical resistance, less clouding due to aging, and maintains transparency for a long time.
Insulation performance: By making the film cushion-like and creating an air layer, it achieves a heat reflux rate equivalent to that of glass.
Light effect: Works well with LED lighting, increasing the effect at night.

Tent membrane structures using ETFE film create transparent and waterproof design roofs, and when combined with steel structures, open new possibilities for future architectural expression. This material greatly increases design freedom while being environmentally friendly, contributing to next-generation architectural projects.
