4000 Series Features
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.
- Seal 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.
