Product Description

This Crystal® Series 1450 aluminum architectural swing terrace door series features a high performance frame structure, an innovative polyurethane thermal barrier technology that thermally breaks conductivity of the aluminum frame to substantially reduce thermal transfer from exterior of door frame 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. Coordinating architectural transoms, heavy-duty hardware, and superior-performance IGU assembly for maximum insulation and sound reduction, makes this series popular with urban developers.
