Tested and Compliant Solutions
Alspec Dualair® component system has been carefully designed to deliver a high performance dual glazed louvre system to the commercial market.
The system provides outstanding results for improved water penetration, allowing larger window sizes to be installed into project designs. Through the use of two louvre galleries inside the one frame, significant sound reduction can be achieved as well as excellent ventilation and shading to keep buildings cool and comfortable.
The Dualair® system has been built on the back of Alspec’s architectural systems knowledge, which balances the needs of both form and function.
