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.
A single-stage system still relies on a single line of defence, where as a multi-stage system adds extra layers of rain defence, instead of relying on a single impact point.
The short answer is yes. Ventuer provides a range of economic and effective screening louvres such as the VL-50CM, VL-100CM, VL-70S, VL-55S.
