Custom Window Systems Impact Vinyl Windows 8100 HVHZ

CWS has been innovating and introducing products that meet or exceed the most stringent coastal requirements, including full High Velocity Hurricane Zone (HVHZ) ratings. The WindPact Plus Series is an example of CWS innovation.

CWS Builds in all of the newest advances in engineering and technology while never compromising on quality. This ensures that the WindPact Plus Series from CWS not only fits better and looks better, it also performs better.

Custom Window Systems WindPact Plus product line is designed for homes in Florida, homes in hurricane impact zones (HVHZ) and coastal markets.

One of the major design features of CWS insulated glass package is placing the laminated piece of glass to the interior of the home. A sacrificial piece of non-laminated glass is placed on the exterior of the home. When a heavy impact occurs, the WindPact Plus design keeps the major breakage outside the home. This allows the interior of the home is relatively free and safe from large, broken sharp and dangerous pieces of glass.
