Vent duct
Vent duct from JUAL unites aesthetics and functionality in one product. This smart solution combines the appearance of a triangular batten with concealed roof ventilation – ideal for modern roof constructions with a minimum roof pitch of 10°, where traditional ventilation openings are interrupted. With the vent duct, you achieve a neat finish while ensuring proper ventilation – simple, efficient and elegant.
Standing seam cover and ventilation in one
When it comes to modern roof solutions, both aesthetic and functional requirements must be met. The roof should not only be durable and watertight – it must also provide a visual expression that matches the building’s architecture. At the same time, technical requirements such as correct ventilation of the roof space can never be overlooked.
With the vent duct from JUAL, you get a patented solution that elegantly unites both needs in one well-designed product. The vent duct is a unique and patented solution from JUAL, which means you will not find similar products from competitors. This makes the vent duct the obvious choice for both professional roofers and architects who wish to combine form and function without compromise.
What is a vent duct?
Benefits of the vent duct
- Integrated ventilation concealed within the design
- Compatible with standing seam and trapezoidal roof profiles
- Reduces work processes on the construction site
- Visually uniform and aesthetic solution
- Patented solution – exclusive to JUAL
- Available in multiple angles and designs
Variants and flexibility
To ensure maximum usability, the vent duct is available in several variants:
-
Straight edge: Perfect for use on flat roof surfaces and standard solutions.
-
Right-angled edge: For installation on one side of a valley.
-
Left-angled edge: For use on the opposite side of a valley.
The sloped model maintains the architectural lines of the roof while discreetly providing the necessary ventilation – in the same way as a ridge vent. The vent duct is designed with cut corners at the tarred end, allowing the bitumen membrane to adhere more tightly and securely.
Ideal for valleys and skylights
- Skylights: When skylights are installed, parts of the eaves are removed, which normally prevents free air circulation in the roof space.
- Valleys: At the junction between two roof surfaces, a visual line is often created where traditional ventilation cannot be integrated without disrupting the design.
- Adjacent buildings: When building against an existing structure – for example, extensions, garages or carports – the natural ventilation of the roof construction is interrupted, which can cause problems with moisture and heat accumulation.
These areas typically present challenges in ensuring proper ventilation of the roof construction. By installing the vent duct, moisture problems can be avoided, and technically correct building solutions can be ensured – all while maintaining the strict and harmonious expression of the roof design.
Ideal for modern standing seam roofing
Standing seam roofing demands a high level of precision and finish. It is a roofing solution increasingly chosen for its clean and stringent appearance, where every line and transition contributes to the overall impression. Both in new builds with architectural focus and in renovation projects where aesthetic enhancement is central, standing seam roofing has become a preferred solution among developers and architects.
With the vent duct, you get a component that fits seamlessly into this aesthetic, while avoiding breaks in the roof surface caused by visible ventilation outlets or sheet metal work. The concealed ventilation ensures that the roof’s sharp expression is maintained – even in technically demanding details such as valleys or connections to skylights and adjacent buildings.
