Entering the home through a floor-to-ceiling full light pivoting front door provides a sense of grandeur that continues through the home with immediate sightlines through the 16-foot wide sliding door at the opposite wall. The distinct black window frames provide a sleek modern aesthetic while providing European performance standards. The Glo A5h Series with double-pane glazing outperforms most North American triple pane windows due to high performance spacers, low iron glass, a larger continuous thermal break, and multiple air seals. By going double-pane the homeowners have been able to realize tremendous efficiency and cost effective durability while maintaining the clean architectural lines of the home design. The selection of our hidden sash option further cements the modern design by providing a seamless aesthetic on the exterior between fixed and operable windows.
