Over-Fascia Vents

The new Thysis Fast-Fix 10mm and 25mm Continuous Over Fascia Vents have a unique low profile design for minimum disruption to the eaves detail. Almost undetectable once installed it still allows a continuous 10mm/25mm air gap.


Extremely strong to resist weight of tiles and crushing by foot traffic. Lightweight and resistant to corrosion and rotting. An integral 4mm grill prevents entry of large insects, birds or rodents into the roof.


The 10mm vent is suitable for conventional cold roofs. The 25mm vent is suitable for warm roofs, flat roofs and

for roof pitches below 15º.


Suitable for buildings with or without soffit overhang, new or refurbished, and buildings with corbelled eaves situations.

The use of over fascia vents allows shallower fascia boards to be used.


Made from 100% re-processed material. Now available in 1m and 0.5m lengths.


The new features include a unique slide- on action, which allows for a secure fast-fix aiding speedy and accurate fitting.
