4000 Series

In addition, the 4000 Series is the best-selling vinyl replacement windows and can be opened from the top or bottom sash, allowing fresh air to circulate throughout your home. Tilt-in sashes make cleaning a breeze and save you the time and frustration of exterior washing, especially on multi-level homes. Easily clean both the interior and exterior surfaces of your windows from the comfort of your home.

Most importantly you can maximize your energy savings by choosing a high-performance SolarZone™ insulated glass package to meet your specific climate challenges. The lower the U-Factor, the less energy you’ll need to maintain the temperature of your home. In warm climates, the lower the Solar Heat Gain Coefficient (SHGC), the more you’ll conserve on air-conditioning. In cool climates, the higher the SHGC, the more you’ll conserve on heating.

More Product Features

Additionally, our windows can reduce your home’s energy loss and improve overall energy-efficiency by creating a barrier against air and moisture infiltration. As a result, you can enjoy a more comfortable home and greater energy savings, up to 12 percent nationwide.

Window World of Joliet’s double-hung windows provide exceptional control of airflow for better ventilation and improved indoor air quality. You can open one sash to allow for a small amount of ventilation or open both the top and bottom sashes for maximum airflow.

Enhanced cavity foam option: The rigid foam is precisely contoured to match specific chambers in the window frame for optimal energy savings. It also creates a superior thermal barrier for reduced heating and cooling energy use year-round.
Additional frame options: For enhanced appearance and ease of installation, two additional frame options also are available.
Maximize your energy savings with a triple-pane glass option: Triple-pane glass systems deliver an added layer of protection to block energy loss providing a more balanced, comfortable indoor climate, while also reducing outside noise.
Energy efficiency is rooted in the design:
- Low-E Glass insulating technology features a virtually clear, metallic coating that acts as a thermal mirror to help keep warm air in during the winter and solar heat out during the summer.
- SolarZone ThermD Intercept Stainless Steel Spacer features a unique, one-piece U-shaped design that stabilizes the panes of glass and creates a powerful thermal barrier. It also helps prevent seal failure.
- Argon is an insulating gas between the glass panes that acts as a thermal barrier on energy loss, counteracting heat, and cold conduction. It also helps block noise infiltration for a quieter indoor climate.
Advanced triple-pane thermal protection: Comparing one glass system to the next can help you determine the best glass for your home and climate challenges. View our glass packages
