High-Performance Window
Zola Windows now offers the American Heritage SDH, a high-performance, all-wood simulated double hung window for landmarked and other historic buildings. Today’s renovations of historic buildings are increasingly focused on achieving maximum energy efficiency for reduced monthly utilities costs and a minimized carbon footprint. In energy efficient retrofits, air tightness and R-values of the windows become crucial, which cannot be achieved with sliding windows. The Zola American Heritage SDH features R-11 glass and triple air seals. At the same time, it maintains an architectural aesthetic due to its historic style, proportions and use of offset glass planes that create the shadow line characteristic of a historic double hung window.
