Series 5500 Aluminum Thermal-Break Double Hung Tilt Windows

A patented anti-bow pin design that prevents sash bowing in multi-story structures sets the Series 5500 Aluminum Thermal-Break Double Hung Tilt Window apart. It features a heavy-duty frame structure and our signature polyurethane thermal barrier technology which substantially reduces thermal transfer from exterior of window to interior. Combined with “intercept” warm-edge glass spacer technology, these 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 easy-to-clean, tilt out sashes and patented anti-bowing technology make it a popular choice with developers.
