Double Hung Windows
Traditional and elegant style. Regardless of your home style, you can’t go wrong with a classic double hung window. Designed so that both sashes move up and down, you’ll have the maximum cleaning accessibility, and the most versatile ventilation possibilities. Open the top, the bottom, or both sashes to suit your needs.
Horizontal Slider Windows
For the greatest unobstructed view of that beautiful scenery surrounding your home, choose our horizontal slider window. The two sashes that make up the window slide back and forth for easy opening and cleaning. You’ll enjoy the air ventilation that the slider offers with up to half of the full window size opening for circulation.

Performance values are based on 3 mm Glass COG
Fiberglass Structural Integrity
High Dimensional Stability
Fiberglass expansion rate is nearly identical to the rate of glass. This low thermal expansion rate translates into virtually zero seal failure. Which makes the entire window system and weather stripping more airtight. Internal stresses are reduced because all the components are expanding and contracting at about the same rate.
Material Expansion Rates
Expansion of various framing materials compared with glass
