Featuring the same slim frame as the 4000 Series Double Hung, the 6000 Series Triple Pane window maximizes energy savings. Triple-pane glass systems deliver an added layer of protection to block energy loss. Their precision-engineered construction features a 1″ thick glass unit, three panes of single-strength glass, two surfaces of Low-E (low-emissivity) technology, two spaces of argon gas, along with the SolarZone ThermD Intercept® Stainless Steel Spacer System for an ultra-efficient energy-saving shield. This thermally optimized glass system provides a more balanced, comfortable indoor climate, while also reducing outside noise. Best yet, 6000 Series windows are covered by Window World of Anaheim’s impressive Lifetime Limited Warranty for complete peace-of-mind.
Comparing one glass system to the next can help you determine the best glass for your home and climate challenges. In the table below, U-Factor represents the rate
of heat flow through the window product – the lower the U-Factor, the less energy is needed to heat a home. The SHGC (Solar Heat Gain Coefficient) represents the solar heat penetrating through the window – the lower the number, the more you’ll conserve on air-conditioning use. Window World 4000 Series Windows with SolarZone ThermD TG2 glass technology are 52% more energy-efficient than clear
double-pane glass windows.

Double-hung windows feature independently moving bottom and top sashes, giving you control over how much ventilation you desire.
Their sleek, narrow frame and sash profiles contribute to a striking low-profile aesthetic, resulting in a broader glass surface.
Additionally, the internal chambers enhance the window’s structural strength, rigidity, and energy efficiency.
Absolutely! Reduce your heating and cooling expenses year-round with the SolarZone™ TG2 Elite™ insulated glass package. During warmer months, it minimizes solar heat gain, reduces glare indoors, and lowers the temperature of the interior glass. In cooler weather, it offers exceptional thermal performance, ensuring warmer glass surfaces for your comfort in winter. This package also complies with all ENERGY STAR standards.
Our double-hung windows are customized to fit the specific dimensions of your home. Reach out to us for details on the size specifications of our various models.
Yes! Our exclusive sill interlock is designed to withstand severe winds and weather conditions. Unlike traditional slope sill designs that may allow the sash to bend under strong winds, our interlocking sash-to-sill technology securely channels the sash into the window frame, creating a robust barrier against the elements.
Window World double-hung windows come equipped with tilt-in sashes, allowing both the top and bottom sashes to tilt inward for easy cleaning of both the inside and outside.
To clean them, follow these steps:
By following these instructions, you can effectively clean and maintain every corner of your double-hung windows
Both single and double-hung windows feature vertically sliding sashes. However, in single hung windows, only the bottom sash moves while the top sash remains fixed. In contrast, double-hung windows allow both sashes to operate freely.
All Window World double-hung windows are installed by our factory-trained team. This includes precise setting, leveling, and caulking to ensure your new windows fit perfectly. Learn more about our window installation process.
To open double-hung windows, both sashes can be slid to create an opening. To lift the lower sash, unlock it and slide it upwards. To open the upper sash, unlock the lower sash and gently lower the upper sash to your preferred position.
To secure your double-hung window, ensure that the locks are aligned properly. Confirm that the upper sash is fully pushed up and the lower sash is completely down for a tight seal. This will allow the locks to engage without any obstructions.
