The A5 Aluminum Series was used throughout the home. The dual pane windows provide cost-effective durability in the temperate climate. The A5 Series boasts a larger continuous thermal break, high-performance spacers, multiple air seals, and low iron glass, which helped facilitate the Passive House standards. For a design where clean lines are key, the thinner profile frame furnishes the contemporary home with an effortless style. The double-pane glazing coupled with European operability is the perfect combination in creating a contemporary home-design worth noting. The homeowners absolutely love the form and function of their tilt-turn windows!
