ETFE
ETFE
ETFE (Ethylene Tetrafluoroethylene) film is durable, highly transparent and very lightweight in comparison to glass structures. ETFE is being considered the material of choice for traditional skylight applications to long span structures and building facades. Few building materials can match ETFE for its impact or presence when you want a structure that stands out from the crowd.
Single Layered Application
ETFE can be applied in a single layered form and are reinforced with either wire cables, light weight steel or aluminum to maintain shape and stability.
Double or Triple Layered Application
In a double or triple layered application, ETFE film incorporates a pneumatic system to maintain air between 2 or 3 layers of film attached in aluminum extrusions and supported by a lightweight structure creating inflated cushions. These cushions are filled with low-pressure air, providing thermal insulation and structural stability against wind or snow loads. If needed, small cables can be used for reinforcement. Under typical loading conditions, ETFE cushions can range from 5 to 15 feet wide and reach up to 200 feet in length.
