Rectangular Weather Louvre

Our rectangular weather louvre is made to measure — enter your exact width and height on the product page and get an instant online price, with no need to wait for a quote. Widths run from 150mm to 1800mm and heights from 150mm to 2400mm, covering everything from a small wall vent to a full plant-room intake louvre.

Each louvre is manufactured from durable, lightweight aluminium in a classic angled-blade design that balances weather protection with airflow, making it the ideal external termination for ductwork systems, facade ventilation and builder’s-work openings. The size you enter is the neck size of the louvre; the overall face is 50mm larger on both axes.

Made-to-order lead times are shown on the product page. Need a size outside these limits? Contact us for a quote — we can make other sizes to order. Standard square and circular weather louvres are stocked for next-day delivery.
