Exterior anodised aluminium grilles — weather protection for ventilation openings

Exterior grilles are mounted on the building facade at the end of the fresh air intake duct or the exhaust duct. Dual role: technical — protects the duct opening against rain, snow, insects and strong wind that could reverse airflow; aesthetic — anodised aluminium finish integrates with modern facades and does not corrode in contact with rain and outdoor environment. Construction: anodised aluminium profiles (silver, bronze or RAL powder-coated on request) with outward-sloping blades — blade angle allows rainwater drainage and prevents direct rain ingress including wind-driven rain. Available with anti-insect mesh included. Applications: fresh air intake for ventilation units and heat recovery units, bathroom and kitchen air exhaust, ventilation openings for basements and plant rooms.
