ETFE skylights walkway Bisonspoor

Buitink Technology made inflatable skylights in the new walkway of shopping centre Bisonspoor in Maarssen. It consists of 6 cushions having a surface area of about 30 sqm. Cushions with a very special and unique shape.

Why ETFE foil

ETFE foil is chosen as material of construction for the skylights due to its self cleaning properties, durability, high degree of transparency and above all for its extreme light weight.

Heat reflecting roof

The roof is consists of 4 layers of ETFE foil (3 air chambers). The outer layer is heat reflecting by using a special IR blocking foil. This foil is light transparent but blocks effectively solar heat transmission (see below graph ''T IR-cut'').

Below graph shows the relation between Transmission and Wavelength of light for standard foil (''T Standard natural") and IR blocking foil (''T IR-cut'').
