Rectangular Louvres — frequently asked questions
Why is there no online price for louvres?
Our louvres are custom made, so we like to discuss your requirements with someone from our team before quoting. Blade pitch, free area, flanges and finish all affect the price, and a quick conversation means you get exactly the right louvre first time.
Can louvres be made to fit my duct or opening size?
Yes — every louvre is fabricated to order in galvanised steel, so we can match your duct size or structural opening, including flanged or framed options.
