In cooperation with her French partner Highpoint Structures, Buitink Technology engineered, delivered and installed ETFE membranes for the skylights of the Château de Randan in department Puy-de-Dôme in France.

This project is part of the renovation of castle Randan to increase comfort and protection against rainfall.

Single layer tensed ETFE foil

A single layer tensed ETFE foil was chosen due to its self cleaning properties, durability, high degree of transparency and its extreme light weight.

To deal with wind force Stainless Steel cables were foreseen around the membranes.

The total surface area of the ETFE membranes is about 450 m².
