Louvers

c/s louvers: letting air in buildings and keeping water out.

C/S introduced the first extruded aluminum louver back in 1948. Since then, C/S has introduced most of the significant advancements in building ventilation technology. From the first dual drain louver, to 100% stormproof louvers, C/S has always been on the leading edge of louver design. And specifiers can be assured of C/S Louver performance, because all C/S Louver systems are tested under real world conditions in our exclusive AMCA/BSRIA test chambers.
