Double Bank Rainproof Ventilation Louvres - PL2 and PL2/DT
Mega Union’s double bank rainproof ventilation louvre system is not only able to satisfy high rainproof performance requirements but also relatively high ventilation requirements; thereby effectively resolving the conflicts between ventilation and rain protection.
Choices of louvre for high rainproof and ventilation performance: double bank rainproof ventilation louvre and rainproof ventilation louvres with more than 2 layers.
Product Specifications
The blade spacing of Mega Union’s double bank rainproof ventilation louvre is 60 mm. Its overall structure is made of anti-corrosion aluminium 6063T5. The louvre blades should not be installed by drilling or fastening with screws but wedged into the structural supporting mullion so as to allow expansion or contraction along the horizontal direction without being deformed or distorted. In addition, this will ensure a uniform appearance of the louvres.
The maximum distance from the centre of the mullion should not exceed 1250 mm. Support points along the vertical direction served to satisfy the actual air flow pressure requirements should be computed & specified by a structural engineer.
