Weather LouvresLatest News

Weather louvres, used in commercial, retail and industrial units are usually installed to protect internal plant and machinery from sand, dust, leaves and rain while maintaining sufficient airflow for the machinery inside. An efficiently designed louvre can mean that less power is required to heat and cool buildings, indicating the importance of what, at first glance, can appear to be a simple structure.


The main objective of a weather louvre is to allow maximum airflow yet provide defence against rain penetration.


There are a number of different types of weather louvre:

• Fixed blade

• Sandtrap

• Penthouse


All are constructed to allow and constrict airflow movement and, at Bradgate, we design the size of openings and the fix of the blades to work with the environment in which the weather louvres are working.


Fixed Blade Weather Louvres

These are weather louvres with fixed, as opposed to moveable blades. Normally used on building elevations to control air intake and discharge, they can consist of narrow or wide blade pitch, to prevent the ingress of rain, depending on the situational weather patterns.


Optional extras include insect screens and powder coating in corporate colours.


Fixed blade weather louvres are usually used in areas where high-level performance against the weather is not required.


Sandtrap Louvres

Sandtrap louvres are used where extreme levels of industrial pollution,sand or dust need to be filtered from the air entering a room containing sensitive machinery.

Louvre blades are arranged vertically so that sand and dust are allowed to drain downwards This design allows them to be maintenance free. Sandtrap louvres are not intended to replace conventional air filters, but they do help prevent larger particles from building up on an internal filter.


Penthouse Louvres

Penthouse louvres are also known as turret louvres due to their shape, and are used to provide weather protection to ventilation openings in building rooftops. They both extract and allow air ingress.

Generally comprised of a four-sided unit, with or without corner posts, and louvres on all four sides, the top is pyramid shaped and is acoustically lined.

When weather louvres are in the design stage, it is important to take into consideration the following factors:

• The airflow required

• Site location and severity of the weather conditions on site

• Building use

• Building aesthetics

• The amount of water penetration permissible
