Double-Hung Series

4000 Series Double-Hung

4000 Series windows from Window World are beautiful as well as remarkably solid, sturdy and stable. Our beveled mainframe design is exceptionally slim and refined. Their sleek construction easily complements any type of architecture. Plus, they’ll never chip, peel, crack or warp, and are maintenance free—their tilt-in sashes make cleaning a pleasure. These windows help to pay for themselves through lower energy costs, freedom from maintenance and increased property value.

Features

  • Reinforced narrow silhouette frame and sash profiles
  • Composite meeting-rail reinforcement allows for secure mounting of hardware
  • End-of-throw cam shift locking delivers increased strength and protection to the recessed lock
  • Smooth and uniform true sloped sill quickly directs water runoff, keeping the exterior of the window clean and attractive
  • Telescoping sill dam provides protection from air and water infiltration, increased structural stability and enhanced beauty
  • Innovative screen bulb seal creates a snug fit that eliminates light and insect penetration between the screen and frame

6000 Series Double-Hung

The superior performance of 6000 series windows starts with innovation. Every precision-engineered component contributes to superior energy savings.

Features

  • Quad 4 weatherstripping at the header
  • Triple-barrier weatherstripping between sash and jamb
  • Compression bulb seal at the sill for further weather protection
  • Hidden screen track produces clean lines

Double-Hung Windows FAQs

What are double-hung windows?

This classic window style allows for both the top and bottom panes of the window to move up and down, operating independently.

Are double-hung windows energy efficient?

Yes! Save on heating and cooling costs year-round with the SolarZone™ TG2 Elite™ insulated glass package. In warm weather, it will reduce solar heat accumulation, minimize interior glare and lower interior glass temperature. In cool temps, it delivers outstanding thermal performance and warmer interior glass surfaces to maintain comfort in the winter. This package also meets all ENERGY STAR requirements.

What are the size dimensions of double-hung windows?

Our double-hung windows are built to fit your home’s specific measurements. Contact us to learn size specifications of our different models.

Does this window style provide long-lasting durability?

Yes! 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.

Great cost and an excellent product! Everything- from the representative to the installation—has been a pleasure. Our windows were installed very quickly, by a friendly, efficient, and clean crew. We may be replacing our doors soon, and Window World of Rockford will be one of our first calls.

Our overall experience was wonderful! It’s evident to us that they take great pride in their work and are a great reflection for the company’s reputation! We are also very happy with the windows we had installed and can already tell a difference in the heating/cooling! Also our salesman, Ed was very professional and took great care in measuring and making sure we were going to be satisfied with our purchase! Thank you Window World of Rockford.
