4000 Series Double Hung

WW DH_Sml Med_3D_2XSolid. Beautiful. Stable. These are the best ways to describe the 4000 Series double hung windows from Window World of Pittsburgh. These incredible products will never chip, peel or crack, even after years of wear and tear. Windows from Window World pay for themselves through lower energy costs, freedom from maintenance and increased property value. Not to mention, our impressive Lifetime Limited Warranty* delivers the peace-of-mind you deserve.

4000 Series Benefits

Best-in-Class Performance Features:

  • Reinforced 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 sloped 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.

Additional Sliding Window Features:

  • Sashes glide horizontally for easy opening and closing.
  • Both sashes lift out for convenient cleaning.
  • Nylon-encased dual brass roller system for smooth gliding performance.
