Clear outer membrane
The first weather layer and a high-transmission daylight surface.
The advanced configuration uses a double-cavity facade formed by three ETFE membranes. It must be adapted to local climate, loads, condensation, drainage and the selected supplier.
Diffuse middle membrane
An optional fixed layer to distribute light more evenly and reduce contrast across crops.
Inner layer and IR-CT
An inner membrane completes the cavities; a mobile ETFE IR-CT screen modulates infrared radiation. A thermoreflective finish applied to ETFE foil can substantially reduce infrared solar gain; some solutions report reductions approaching 45%, subject to confirmation against the selected product’s technical data.
Integrated arch
The glulam arch sits within the envelope assembly; Keder profiles, aluminium, seals and thermal breaks are detailed through engineering.
Optional insulated wall
For an east-west orientation, the opaque facade can target high thermal resistance and concentrate technical services and equipment.
