Air cushion roof for public square Bisonspoor
Buitink Technology realized an air inflated ETFE cushion roof in the centre part of a public square in shopping centre Bisonspoor in Maarssen (the Netherlands).
The air cushion roof consists of 18 ETFE cushions covering a total surface area of 315 m2.
Heat reflecting ETF roof
The roof consists of 3 layers of ETFE foil (2 air chambers. The outside layer is coated with a heat reflecting so called "infra red block". The infra red block foil still is very transparent for light, but blocks effectively heat from sun-radiation.
In below graph a comparison of the transmission is shown between a standard ETFE foil (''T Standard natural'') and an IR block foil (''T IR-cut'').
|3 layer ETFE clear||1 layer IR-cut / 2 layer ETFE clear|
|Direct energy transmission||0,74||0,36|
|Light transmission grade||0,71||0,44|
|Light reflection grade||0,24||0,11|
|UV- transmission grade||0,45||0,19|
|Solar heat gain coeffincient||0,75||0,41|
Air equipment and ss tubing is delivered and installed by Buitink technology as well.
