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
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'').
