Roof Hatch for Multiwall Polycarbonate


Product Information

These Polycarbonate roof vents are suitable for a new installation of a polycarbonate roof or for updating/adjusting an existing polycarbonate roof. 

These easy fit vents are 750mm long x 550mm wide (external sizes) and are fully weather proofed to BS6375 & BS5368 (parts 1, 2 and 3) thanks to integral gaskets and snap in glazing beads.

The telescopic brass opener (supplied as standard) combines generous ventilation with security and can be internally disconnected. It also allows full opening of the roof vent for ladder access and maintenance to adjoining building.


  • 750mm x 550mm (29.5” x 21.625”) – external size.
  • 710mm x 510mm (28” x 20”) – fully open internal aperture size.

Here at TW Plastics, we offer these PVCu Roof Vents for use with Polycarbonate Roofing in two colours (White or Brown) and designed for two Polycarbonate thicknesses (for 16mm or 25mm).

Remember: you have to keep the ‘cut out’ material to glaze the roof vent, so put it somewhere safe!
