CSQ / WSQ External Air Louvres - New design

External Louvres are designed termination of the ventilation ductwork. Installed on the external walls, Louvres make a  difference to a building's overall aesthetics.

That is why we’ve modified the design of our rectangular weather louvres. CSQ Wall-mounted intake and WSQ exhaust louvres in sizes up to 600x600mm:

  • are manufactured from formed sheet metal
  • the frame of louvre is 30mm wide
  • the CSQ external weather louvre in equipped with QLIN-IN wire mesh

Thanks to the implemented modification, weather louvres are more aesthetically pleasing and cheaper.

We’ve tested external louvres in accordance with EN 13030: 2001 - classification, rated A – D designates the “effectiveness” Class of the weather louvre against water (rain) penetration.

External louvres in larger sizes over 600x600mm are still manufactured using blade profiles QPPC, QPRC and QNT corner pieces, therefore the frame width is 40mm.
