G5 Slate Vent

Categories: ,


The low-profile cowl is geometrically the smallest available in the marketplace for the air capacity, projecting only 85mm above the roof surface.

Not recommended for high-level use as its large air capacity and wide spacing would tend to leave stagnant air pockets between units.

The G-Range are suitable for roof pitches between 20° and 60°.

Guaranteed actual net free ventilation area: 20,000mm².

  • Underlay opening protector, integral 4mm insect screen, and ventilator throat or extension sleev meet design requirements of BS 5250.
