The Vinyl, The Spacer, The Glass

The Vinyl

The design of the window and the quality of the vinyl extrusion insures the beauty and performance of the finished product. The window systems of American Window are designed and extruded by our partner, Deceuninck Plastics. Deceuninck is recognized as a leading extruder of vinyl window and door systems in the United States. Dayton Technologies’ parent company, Deceuninck Plastics, is acknowledged as the world’s largest vinyl profile extruder. www.deceuninck.com

The Spacer

When selecting windows for your home you want to look for products that give you the quality and performance your home deserves. A good place to start is to look for windows that have Intercept insulated glass.

Intercept is a patented “Warm Edge Technology” spacer system that features a unique one-piece, U-channel design that creates an effective thermal barrier. It, therefore, reduces conductive heat loss through the window.

Intercept’s sealed, one-piece design makes it stronger and better at retaining insulating gas than conventional spacer designs. The Intercept spacer is so energy efficient that it keeps the edges of the window glass warmer, making your home more comfortable in the winter. www.ppgglass.com

The Glass

American Window offers some of the most advanced glass technology in our window systems. The optional Solarban 60 Low-E glass is a value-added product that brings energy savings and comfort to your home.

PPG Solarban 60 Solar Control Low-E glass is engineered to provide year-round comfort, keeping your home cooler in the summer by keping out solar heat and warmer in the winter by keeping furnace heat inside.

PPG Solarban 60 Low-E glass helps your home become more energy efficient and comfortable thanks to an almost invisible, microscopically thin coating that blocks out unwanted solar energy and keeps in furnace heat. Additionally, Solarban 60 Low-E significantly reduces the fabric fading effects of ultraviolet light and resists condensation and it’s effects on your home environment.

PPG has pioneered the glass technology found in the world’s best windows, like those of American Window. www.ppgglass.com
