All our air inlets can be provided in a daylight version, made of opal or clear polycarbonate.
The daylight valves are made out of a 25 mm (4 chambers) polycarbonate sheet. Around this polycarbonate sheet a PVC U-profile is mounted. This ensures a proper closing of the polycarbonate chambers and therefore still air and good insulation.
Mounting and settings are like a normal air inlet.
