Fixed windows are a popular choice for applications that call for maximum viewing space and high energy-efficiency.  The strong aluminum frame, polymer thermal barrier and warm edge spacer combine to create a durable window that is perfect for residential, commercial and mixed-use properties.

Our U Series fixed windows blend the strength and proven structural performance of classic thermal barrier aluminum windows with technologically advanced polyamide thermal struts.  Integrated throughout the frame and sash, this new system enables these windows to achieve the required performance for your product.
