6200Project Description
This Crystal® ThermoBlok™ aluminum heavy commercial slider window features a high performance frame structure, an innovative polyamide thermal strut technology that thermally breaks conductivity of the aluminum frame to substantially reduce thermal transfer from exterior of window to interiors, and “intercept” warm edge glass spacer technology. These integrated features reduce heating and cooling loads on HVAC systems, providing long term energy efficiency and utility savings to property owners. This series is ideal for multi-story commercial projects where high strength structural integrity of the window frames is essential. The ability to aesthetically match this slider series with 6000 commercial tilt window series makes it an ideal fenestration solution for developers.
