Double-Hung Series

4000 Series Double-Hung

4000 series windows from Window World of Fresno 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. You will find that 4000 series vinyl frames will never chip, peel, crack or warp, and are maintenance free.


  • Reinforced narrow silhouette frame and sash profiles create a low-profile design for expanded glass area
  • Composite meeting-rail reinforcement allows for secure mounting of hardware and helps reduce the transfer of energy
  • End-of-throw cam shift locking delivers increased strength and protection to the recessed lock (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
  • Telescoping sill dam delivers a triple payoff: protection from air and water infiltration, increased structural stability and enhanced beauty
  • Our proprietary sill interlock withstands extreme wind and weather
  • Innovative screen bulb seal creates a snug fit that eliminates light and insect penetration between the screen and frame while aiding in easy screen installation and removal

Triple-Pane Glass Technology

Windows are approximately 80% glass, so choosing a high-performance glass system is the ideal way to maximize energy efficiency and conserve year-round heating and cooling energy consumption.

  • A 1″ thick glass unit
  • Three panes of single-strength glass
  • Two surfaces of Low-E (low-emissivity) technology, which maintains your indoor temperature
  • Two spaces of argon gas, which helps block noise infiltration and acts as a thermal barrier
  • SolarZone ThermD Intercept® stainless steel spacer system for an ultra-efficient energy-saving shield

6000 Series Double-Hung
