Air-cushion roof Hellebrekers

Buitink Technology has realised the transparent and sunlight-regulating ETFE air-cushion roof over the atrium of Hellebrekers’ new head office in Nunspeet.

The air-cushion roof is made up of 12 ETFE cushions with a total surface area of approx. 350 m2.

Air-pressure controlled blinds

The roof comprises four layers of ETFE foil (creating three air chambers). The patterns printed on the middle two layers run in different directions. Using air pressure to control how far apart or close together these layers are held controls the level of shade. Bringing the layers close together produces maximum protection from sunlight and the more they are separated, the greater the light transmission.

Sustainable choice

The choice of ETFE sheeting and its use as an air-cushion roof are sustainable thanks to the high insulation values of the roof and the eco-friendly properties of the ETFE sheeting itself.
