Energy Efficient Window

Energy efficiency is no longer a premium luxury for building professionals; it is an expected standard feature. The Envision Series windows and Advantage Series picture windows and patio doors exceed the new Energy Star® 6.0 window standards—a clear sign of superior window performance which can help lower energy bills by more than 12%.

Energy efficient window framing

Our standard double-pane, LoE coated, double-strength glass can dramatically reduce window heat loss. The interior glass stays warmer in cold temperatures, protecting homes from the chill of winter. In the summer, the windows transfer less heat by filtering the sunlight and reflecting it back outdoors. That means lower energy costs, no matter the climate.

Beyond Energy Star 6.0, Beyond Lower Costs

Our Vector windows and doors don’t just exceed Energy Star 6.0 windows’ superior energy efficiency standards—they also provide exceptional interior comfort. The LoE coating on every pane of glass in Vector windows and doors helps to protect interiors from sun damage by blocking harmful ultraviolet rays without noticeably reducing visible light. Our windows and doors also deliver more comfort and create less condensation than conventional alternatives.

Traditional metal spacers conduct heat and cold, which causes unsightly condensation at the edge of the glass that can contribute to unhealthy mold growth. By implementing a warmer edge around all sides of the window, our Vector window and door designs strike at the heart of the problem. Vector windows and doors use an industry-leading, non-metallic insulating structural foam spacer which helps reduce condensation and allows for more comfortable household humidity levels.
