Transparent Film

Birdair’s ETFE, or ethylene tetrafluoroethylene, is a transparent film suitable for large- and medium-scale architectural projects. Used for both roofs and facades, ETFE offers various design options due to the material’s light weight, flexibility and transparency, according to the company. ETFE film can be used in place of traditional glass and plastic for permanent or temporary structures. When used in a two- or three-layer model incorporating an air space, the film provides an insulating capability as effective as insulating glass, according to the company. ETFE films can be custom made with UV protection and light control, as well as options of transparent, matte, white, or printed finishes. Due to its nonstick surface, ETFE resists airborne pollutants and odors. The recyclable material can last more than 20 years without losing transparency or strength, according to the company.
