Series 480

Project Description
This Crystal® ThermoBlok™ aluminum heavy commercial swing terrace door series 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 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, between-the-glass blinds, and extra thick glass IG assembly for greater insulation and sound reduction, makes this series popular with urban developers.
