Construction materials

Our product range of building items comprises ventilation grills, double skinned wall sleeves, chimney caps and rain hoods, terminal guards, VEWI valves and a variety of products for project finishings.

  

The ventilation one way valve is suitable for use with fan operated kitchen hood extraction units.

The VEWI-Valve should be fitted vertically between the outlet duct and the extraction hood. 

When the kitchen hood/extractor fan is switched off, the valve plates inside the VEWI drop down, preventing outside air or previously extracted air returning. Whilst the extractor is off, natural ventilation flow from the room to the outside is still allowed out through the valve.

A terminal guard prevents bird entry and obstruction of rainwater pipes and chimneys. There are galvanized and stainless steel terminal guards available in diameters from Ø 60 to 250 mm.

Available in single  and double width versions 

The air intake opening cover plate is equipped with louvers for rain protection.

Suitable for use on exterior walls.

The chimney caps are made from aluminium.

Available range Ø 120 mm to Ø 250 mm.

The rain hoods are produced in (Sendzimir method) galvanized aluminium,.

Available in diameters from Ø 92/98 to Ø 500 mm.

This aluminium tube is highly flexible and is produced from a single spiral of profiled aluminium.

Because of the special folded seam both a very high air tightness and flexibility is achieved.

• Air treatment systems
• Fume/wet air extraction systems 

Our double skinned wall sleeves are made from galvanised steel (Sendzimir method).
