SingleLok Single Hung

Distinctive Style & Superior Design

The Singlelok single hung window is designed to enhance your home’s appearance while increasing its comfort level. The low profile sloped sill maximizes rain runoff. The new soft curved welded sash design provides a classic “wood like” interior appearance while allowing maximum glass area for your viewing pleasure. The engineered channels allow for dual layers of weather stripping to minimize air infiltration. Efficient ¾” Low E insulated glass maximizes energy performance and minimizes unwanted sound transmission, reducing not only heating and cooling bills, but also outside noise. Finally add the beauty of the maintenance free finish of Sunshield vinyl, which retains its sheen year after year.

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. American Window is partnered with the leading window extruder in the industry, Vision Extrusions Group Ltd. Together, American Window and Vision Extrusions work hard to provide an unmatched product that is second to none.

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 InterceptR insulated glass.

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

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.
