Ventilation Cowl for pitched roofs 11-55°
The ventilation cowl is mounted where the roof surface is penetrated by exhaust and ventilation pipes. This model can be adjusted from 11° to 55°. The cowl can be fixed to the roof and bitumen can be welded to the cowls flange.
Adjustable cowl for pitched roofs
A ventilation cowl for pitched roofs must be adaptable to the roof slope, ensuring that the penetration is positioned correctly in relation to the roof surface while maintaining complete tightness. JUAL’s solution can be continuously adjusted from 11° to 55°, making it highly versatile and suitable for many roof types – from gently sloping roofs to steeper constructions.
This flexibility reduces the need for customised solutions and makes it possible to use the product across a wide range of buildings, regardless of roof pitch.
Safe and adjustable solution
When installing ventilation pipes, exhausts and soil vent pipes in pitched roofs, it is essential to have a penetration solution that ensures both tightness and flexible adjustment to the roof slope.
JUAL’s ventilation cowl for pitched roofs 11–55° is designed precisely to meet this need. With its adjustable angle and weldable flange, this cowl provides a reliable and aesthetic solution for roof penetrations in both new builds and renovation projects.
Tight integration with bitumen
The ventilation cowl is supplied with a flange that allows the bitumen to be welded directly onto the cowl. This ensures a 100% tight solution and makes the cowl ideal for use on roofs where bitumen is the primary roofing material.
The tight integration with the bitumen provides effective protection against water ingress, condensation and frost damage – extending the lifespan of both the roof and the building.
Regardless of the installation type, the cowl ensures a tight and reliable solution that maintains both the function and the visual coherence of the roof.
