ETFE air cushion dome Biosintrum
Buitink Technology delivered and installed an ETFE air cushion
dome for the BREEAM Outstanding Biosintrum building of
The dome has a free span of 5.8 meter and is made of 4 membrane
sheets (i.e. 3 air chambers). An air cushion dome of ETFE foil is
extremely durable. Both the foil itself as well as the residual
production waste is to be recycled completely. It has a long life
cycle of at least 30 years and the material consumption is
extremely low (it weighs less than 3 kg/m²). It too has excellent
self-cleaning properties and is transparent for the full light
spectrum (including UV light).
Print on toplayer ETFE
The top layer of the foil has a print to reduce the light
transmission factor of the dome.

Engineering of the dome
Biosintrum winner in category "buildings"
The community of Ooststellingwerf granted Paul de Ruiter
Architects the order to design the extremely durable BREEAM
Outstanding Biosintrum as the breathtaking centre of the
"Ecomunitypark". The Biosintrum is an energy neutral building,
composed of more than 80 % bio materials and inspires both students
and professionals. The jury said this contribution is an example
project of an integrated approach of durable and "green"
engineering with bio based materials. The jury finds it very
inpiring to see that the target group is involved in the
design and construction of the building.

To realize our projects we perform complete strength and load
calculations. A selection of analysis with various loads on the
dome is shown below.
