4000 Series Vinyl Replacement Windows
Featuring a beautifully refined silhouette and advanced energy-saving technology, our 4000 Series delivers exceptional style, strength, energy efficiency and value – everything today’s homeowners are looking for in a quality replacement window, and more.
This next-generation 4000 Series is precision-engineered to meet or exceed stringent ENERGY STAR® requirements, providing triple-pane energy-saving performance in a dual-pane unit. The dual-pane, double-strength insulated glass, thermally optimized frame and sash and non-conductive composite reinforcements are just part of the advanced energy engineering that puts 4000 Series Windows in a class all their own – premium window performance with everyday affordability. With Window World Windows your home will have a fresh, energy-efficient, low-maintenance solution back by an all-inclusive lifetime limited warranty.
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 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.
Both sashes of Window World Double-Hung Windows tilt in for easier, safer cleaning from inside your home.
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.
