PolyPour Aluminum and Sunshield™ Welded Vinyl

PolyPour Aluminum Thermal Break Windows

Not all “aluminum windows” are the same! Our commercial-grade aluminum windows feature a thermal break that separates the inside metal from the outside metal with very high-density catalyzed polyurethane. Generically, this engineered design is called “pour and de-bridge” in reference to the extrusion process. We just call it PolyPour. These windows set our aluminum lines apart from conventional, old-fashioned typical aluminum windows that have no thermal breaks. Among those that do, be careful to make sure you notice the differences. For example, ours feature wide thermal breaks in the jambs, heads, sills, and all sashes of our windows; and the breaks align for maximum thermal performance. Lesser windows have thinner breaks, may not align, and may even have no thermal break in their sashes or sills. PolyPour windows from Don Young Company fight condensation and have significantly better insulating values than any cheap “builder grade” aluminum window. If you want to learn more about thermal breaks for yourself, we recommend you go to this industry site and then click on Advanced Thermal Break Designs for generic technical information.

Thermal Effect Series 8200 sill set upon dry ice proving the thermal effect of our PolyPour aluminum thermal-break design. Conventional aluminum windows would frost completely in the same test.
Sash Our sashes feature among the thickest walls available in residential windows, double wool pile weather strips, and a significant PolyPour thermal break chamber.
Aluminum Window Strength Our PolyPour aluminum window is incredibly strong. Typical aluminum windows can’t be compared to the mass and density of our Series 8200 jamb under the two contractors.
