High Point - cushions with screen printing on the roof

Cushions made of ETFE

The canopy made of ETFE cushions consists of two, three or four layers of film that retain a volume of air, ensuring the cover a good insulating power and giving the roof its strength.
Each cushion is closed at its edges by a rim hem that is attached to a peripheral frame consisting of extruded aluminum profiles and molded rubber ribbons. This waterproof frame, screwed on the primary metal framework allows drainage of water.
Brought
Transparent, the airbags are ultra-light canopies and allow impossible reach with most other construction techniques. Rectangular cushions may have a width of about 4 meters and a length (in theory) not limited. Triangular or circular cushions allow for even greater spans.
The lightness of the system, 1.5 to 2kg / m² (a factor of 50 to 100 lighter than glass), allows in many cases a substantial saving in the construction of support structures, and ranges and impossible connections to make glass.

Isolation / U value
An ETFE cushions roof provides relatively high thermal insulation values.

Solar regulation
Screen-printed or colored, the ETFE membrane can moderate the effects of light and heat. By a positive / negative printing set and the variation of distance between two membranes, the light supply can be controlled by simply changing the pressure in the cushions.
