Ventilation components

In the field of ventilation components, we produce two different ranges. Our injection-moulded polystyrene ventilation products are perfectly resistant to various weather conditions. The different designs allow a wide application of these products in both outdoor and indoor installations. We offer a wide range of colours to ensure an aesthetic and well-matched environment.

We also manufacture a wide range of PVC vent bonnets using thermoforming process. Our ventilation bonnets are available in single-wall or double-wall (against condensation) versions and have a diameter of up to 400 mm. Of course, covers are also available for all ventilation bonnets.
