ACOUSTIC WEATHER LOUVERS

Proven performance and tested to the requirement in the 4th edition of HEVAC Technical specification.
SIACs performance louvers provide ventilation whilst maintaining rain defence into the building when high winds and rain combines. The system balance the rain defience and aerodynamic performance so that maximum airlflow can be achieved with the highest rain defence possible. It can be available in Single and Double bank with a wide range of colors and finishes.


Single bank Louver

The basic single bank louvers are usually mounted in row of horizontal blades shaped and use on the external walls of buildings and provide low resistant to air intakes or discharges and yet minimize the infiltration of rain. Banks of panels can be made to any practicable size or shape and provide a clean appearance at a very competitive cost. Standard construction equipment screens are sight proof from horizontal sight line. Louvers are supplied either on mounted concealed mullions for continuous appearance or as individual framed panels to form an architectural feature of a building.

Double Bank

Double bank louver

Double bank performance Louvers comprise double row of horizontal blades shaped and positioned to minimize the ingress of water up to 99 % and designed for low resistance to airflow and against water infiltration into the building when high wind and rain combine. It provides sight proof from all angles as equipment screens. Louvers are supplied either on mounted concealed mullions for continuous appearance or as individual framed panels to form an architectural feature of a building.
