Cushion roofs made of ETFE foil with sun protection
ETFE cushion roofs can be provided with sun shade prints to
reduce the Solar Factor.
Shading prints on ETFE foil
Shading prints can be applied in 2 different ways:
- Prints on one or more layers of ETFE foil
- Control system, where 2 opposite layers of an ETFE cushion have
Principle of controlling sun shade
Pressurizing an air chamber between 2 foils with prints will
open the sun shade system, acting as "blinds". When reducing the
air pressure the 2 layers of foil will stick together and the sun
light transfer is reduced ("blinds are closed").
