DHPWLiving.jpgDistinctive Style & Superior Design

The Grandlok window is the ultimate in “beauty, efficiency and strength, designed to enhance your home's appearance while increasing its comfort level.” The beauty of the new soft curved welded sash design, equal lites of glass and the unique cove mold look of the welded master frame offers a more traditional wood window interior and exterior appearance. Energy efficiency, security and sound transmission performance are achieved by ¾” “Warm Edge” insulating glass, maximum weather stripping and precisely engineered interlocking vinyl window extrusions. The strength of the Grandlok window comes from heavy wall construction, fusion welded frame and sashes, interlocking meeting rail and a low profile one piece sloped sill. Finally the natural beauty of the maintenance free finish of Sunshield vinyl, which retains its sheen year after year.

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

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
