ETFE air cushion dome for Krinkels

Buitink Technology delivered and mounted an ETFE air cushion dome for the new headquarters of "Krinkels" in Breda (Holland).

The headquarters is a two-story building. It's entrance is a circular atrium with a large round ETFE roof with a diameter of 7 meters. It offers free entrance of natural daylight. This atrium is the main centre of the building, characterized by the monumental tree "Ficus Amstel King". A symbol for the strong growth of the Krinkels group.

Why an ETFE aircushion dome

The dome has a free span of 7 meters and is composed of 4 foil layers (and thus 3 air chambers). ETFE foil is chosen as material of construction due to its durability:

  • 100% recycling of cutting waste;
  • expected lifetime of more than 30 years;
  • can be fully recycled;
  • limited use of materials and so very light weight (3 kg/ m2);
  • self-cleaning properties;
  • Fully transparent for the complete visible light spectrum and ultra violet.

To lower the g-value the top layer of the ETFE air cushion roof is coated with a solar reflective print.
