Product Description

CTP-5100 AW-Rated fixed windows feature a unique mulling system that’s built into the window master frame. This eliminates the need for separate mullion pieces, thus cutting down installation time and costs without compromising overall unit integrity.
This Crystal® ThermoBlok™ aluminum picture window features an innovative polyurethane thermal barrier 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 both residential and light commercial applications. It’s value price point, easy-to-clean tilt out sashes, and coordinating architectural circle top shapes make it a popular choice with developers.
