These PVC roof windows are for 16mm, 25mm and 35mm polycarbonate sheets and are used in conservatories to provide ventilation.
These PVC roof vents for polycarbonate sheet come pre-welded and are ready to install, simply cut the polycarbonate sheet using the templates supplied with the vent, taking care not to damage the piece your are removing as this is required for the lid. Then using the sealant and gaskets supplied, fit to your existing sheet. If you are installing new sheets this can be done at ground level, alternatively this can be performed in existing polycarbonate roofs.
With a solar powered extractor fan, in full sunlight, these vents will discharge 25M3 of hot air an hour through the roof. The underside of the SV100 Vent has push-buttons for ON/OFF and Reverse Air Flow, whilst the 300 Vent has an additional button to operate its’ built-in battery. The SV100 is finished in white and the SV300 has a Chrome finish.
The Install Kit (sold separately part SVKIT) contains a 114mm Arbour saw to cut a neat circular hole through the roof sheet and clear Stixall Adhesive to both secure and seal the vent.
