Abstract
A composite construction for windows and doors has one or more components of the frame and/or window unit fabricated as a composite having a structural foam intermediate member onto which exterior and interior aluminum extrusions are mechanically and adhesively attached. The foam member functions as a structural bridge between the extrusions, as a thermal break and may also provide support for an internal seal to prevent air infiltration.
