4000 Series Double Hung

double hung 4000 seriesWith triple-pane performance in a dual-pane design, the 4000 Series delivers quality energy savings in a class all its own. The thermally optimized frame and non-conductive reinforcements are the secrets to this window’s efficiency. Encased in a beautifully refined silhouette, the 4000 is an affordable option that meets ENERGY STAR requirements for the ultimate in insulation.

 Performance Features:

  • double hung 4000 seriesReinforced narrow silhouette frame and sash profiles make a statement of style with their low-profile design. The result is a beautiful and expanded glass area. At the same time, internal chambers increase structural integrity, rigidity and energy efficiency.
  • Composite meeting-rail reinforcement allows for secure mounting of hardware; the non-conductive material helps reduce the transfer of energy.
  • End-of-throw cam shift locking delivers increased strength and protection to the recessed lock. It also includes an “unlocked” indicator.
  • The smooth and uniform, true sloped sill quickly directs water runoff without the use of weep holes, keeping the exterior of the window clean and attractive.
  • Our telescoping sill dam delivers a triple payoff; protection from air and water infiltration, increased structural stability and enhanced beauty.
  • When extreme wind and weather hit, our proprietary sill interlock stands strong. Traditional slope sill designs can allow the sash to bow during powerful winds, but with our interlocking sash-to-sill technology, the sash is channeled firmly into the window frame for a unified wall of strength.
  • Our innovative screen bulb seal creates a snug fit that eliminates light and insect penetration between the screen and frame. It also aids in easy screen installation and removal.
