Robust TUFF-VENT is a strong and durable fully louvred doorset offering the maximum free airflow whilst maintaining strength and durability. A standard 2mm galvanised steel louvre vane is used throughout, welded at every junction for additional strength. Side panels and overpanels can also be manufactured to make up large openings where large doors may be impractical.
When calculated on a 1000mm x 2100mm over frame door, a free area of 55% is achieved (based on the area of louvres only this equates to 72%). Robust TUFF-VENT doors are fully CE compliant and can be polyester powder coated in a standard range of colours.
