Ventilation cowl 6°

The ventilation cowl ensures a tight roof penetration for exhaust pipes.
It is designed with a flange for bitumen installation and a fixed slope of 6°, making it particularly suitable for bitumen roofs with a slight pitch.

The ideal solution for low-slope roofs

For any roof penetration, it is essential to ensure both tightness and long durability. Especially on roofs with a low pitch, there are increased demands on materials and solutions that can handle rainwater and weather exposure without risk of ingress.

With JUAL’s ventilation cowl 6°, you get a specially designed solution that combines technical precision with high functionality and easy installation – ideal for buildings with bitumen roofing and a low roof slope.

What is a ventilation cowl 6°?

The ventilation cowl 6° is designed to ensure a tight and professional penetration where ventilation pipes, exhaust pipes or soil vent pipes pass through the roof surface. What makes this model unique is the fixed 6° slope, which makes it suitable for low-slope roofs, typically flat roofs or roofs with inclinations from 1:40 upwards.

The 6-degree slope ensures that water is naturally directed away from the cowl and does not accumulate around the penetration – an essential feature on roofs where water otherwise has a tendency to stagnate.

Flange and tightness with bitumen

The ventilation cowl is supplied with an integrated flange, allowing the bitumen to be welded directly onto the product. This creates a watertight and vapour-tight transition, eliminating the risk of leaks at the penetration – a critical detail, especially on roof types without natural drainage.

The solution is suitable for both new builds and renovation projects, where the demands for constructional tightness and durability are high.

Aesthetics and architectural coherence

JUAL’s ventilation cowls are manufactured from robust, weather-resistant materials that withstand UV radiation, rain, snow, frost and high temperature fluctuations. This ensures durability for many years – without the need for ongoing maintenance.

Although functionality is the top priority, the visual appearance also plays an important role. JUAL’s ventilation cowls – including the 6° model – have been developed with a discreet and architecturally neutral design that suits both modern and traditional buildings. The smooth surface and precise form ensure that the cowl does not detract from the overall roof appearance but instead appears as a natural part of the construction.
