Combining the ventilation that comes with operating windows and the maximum visible area of a fixed window, series 825 projected products are an excellent choice for commercial, residential and mixed-use applications.  They can also be combined with fixed windows as a series 875.

Our U Series projected 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 project.
