Top for ventilation cowl

Top for JUAL ventilation cowl. Available for black lacquered aluminum hoods in both standard and impact resistant versions, as well as for PLASTIGEN hoods in both ASA and PVC.

Flexible replacement and maintenance

Ventilation cowls are an important part of a building’s ventilation and exhaust system, and it is essential that they function optimally and remain sealed – even after many years of use. At JUAL, we offer loose tops for ventilation cowls, making it easy and cost-effective to replace a damaged or worn top – without the need to replace the entire cowl.

Our loose tops are compatible with JUAL’s existing ventilation cowls and are available in several variants to match material, function, and design. This practical solution extends the lifespan of the installation and ensures continued efficient ventilation.

Also fits PLASTIGEN cowls in ASA and PVC

In addition to aluminium, we also offer loose tops for PLASTIGEN ventilation cowls, manufactured from durable plastic materials such as ASA and PVC. These materials are weather-resistant, UV-stable, and well suited for lightweight roofs, industrial buildings, and technical installations where low weight and easy installation are important.

This means you can easily replace the top of an existing PLASTIGEN cowl if the old one is worn, discoloured, or damaged – without having to replace the entire component.

For both standard and rainproof versions

The loose top is available for black-painted aluminium cowls in both:

Standard version – for typical roof conditions
Rainproof version – for exposed areas or roofs with high exposure

Whichever version you currently have installed, you can find a suitable spare part that maintains the same functionality and performance. The rainproof version provides extra protection against penetrating rainwater and is ideal for west-facing or exposed roof surfaces where the weather is often harsh.

For maintenance, renovation and repair

Whether you are an installer, technician, facility manager or building owner, it is important to think long term when it comes to roof penetrations. With a loose top from JUAL, you get a maintenance-friendly solution that allows for quick and efficient repair without the need to alter the actual roof penetration or roof covering.

The loose top is easy and secure to install, ensuring that the installation continues to perform as intended – both technically and aesthetically.
