Green aluminium is aluminium produced with a significantly lower carbon footprint than traditional methods. Green aluminium typically produces 2-4 tonnes of carbon per tonne of aluminium, compared to black aluminium producing 12-14 tonnes.

Free area is a rough proxy, while actual performance is governed by pressure loss. It is calculated by measuring the smallest gap in the louvre blades and expressing it as a percentage of blade spacing.

If you need airflow and weather protection, drainable louvres are designed to manage wind-driven rain by capturing and directing water away.
