As one of the industry’s top sustainable window companies, we’re committed to conservation and the protection of our environment. Because of their energy efficiency, homes with our windows & doors don’t require as much electricity to heat and cool, which decreases unnecessary carbon emissions.

We’ve also taken a number of steps to reduce the waste expended to create them. The material scrap generated by our manufacturing operations is recycled or reused. This includes all of the major components of our products—glass, vinyl, and metal. In addition, our saws and glass cutters utilize optimization software to greatly reduce the amount of material waste generated.

We have worked to make our factory as green and sustainable  as possible. To this end, we’ve installed high-efficiency lighting and programmable thermostats, and we’ve optimized the layout of our equipment to significantly cut our energy usage. Moreover, our production facility does not create any emissions that are harmful to the environment.
