Types of Ventilation products:

Roof penetrations

Roof ducts are used to lead ventilation ducts, flues or exhaust ducts outside through the roof. They are suitable for mechanical ventilation, kitchen and bathroom ventilation systems and extractor hoods. Roof ducts are available in different diameters and materials, depending on the type of roofing and application.

Wall penetrations

Wall ducts serve as ventilation or exhaust ducts via the facade. They are used for exhaust ventilation, air supply for fireplaces or ventilation systems. These ducts often consist of a tube with a grille or cap on the outside to keep rain and vermin out.

Roof duct tiles

Roof penetration tiles replace a standard roof tile and contain an integrated opening for ventilation or smoke exhaust. They ensure a watertight and neat connection of roof penetrations and are available in various colours and models to match the roof covering.

Storm collars

Storm collars are placed around roof penetrations to prevent leaks. They provide a watertight seal and protect the penetration from rain and wind. They are often combined with a flexible sleeve for optimum sealing.

Wire mesh grids and top covers

Ball wire grilles and top caps are placed on the end of ventilation ducts and flues to prevent birds, leaves or other debris from blocking the opening. They ensure free air flow and protect against external influences.

Brackets and mounting

Brackets and mounting materials are used for mounting ventilation ducts, roof penetrations and wall penetrations. They ensure a stable and safe installation and are available in different sizes and designs, suitable for different surfaces.

Ventilation plates and grilles

Ventilation plates and grilles are used for air supply and exhaust in walls, doors, floors or facades. They promote good air circulation and prevent moisture problems. Available in different materials and designs, matching aesthetic and functional requirements.

Lids and flanges

Covers and flanges are used to close or connect ventilation ducts and feedthroughs. Flanges provide a firm connection between different ventilation components, while covers can seal openings when they are (temporarily) not in use.
