FEATURES

Simply put, “Passive House” is a new benchmark in sustainable design. It’s a building standard that maximizes air tightness and insulation, in order to minimize energy costs. Openings such as windows and doors are the greatest source of heat loss in any home, and so our industry developed new technology to meet this demand.

Here at WindowFix, we offer the most energy efficient windows and doors on the market, sourced from established European brands, or from sources closer to home, such as Alpen High Performance products, the only American made window certified by the Passive House Institute-US (PHIUS). We are also experienced, certified Passive House tradesmen, and would be happy to assist with your next project.

Available in standard and custom colors, multiple styles and configurations
