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.

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.

The bottom and top sashes of double-hung windows move independently of each other, allowing you to customize the amount of ventilation you want.
Reinforced narrow silhouette frame and sash profiles make a statement 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.
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.
Our double-hung windows are built to fit your home’s specific measurements. Contact us to learn size specifications of our different models.
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.
Double-hung windows from Window World are made with tilt-in sashes. This means both the top and bottom sashes can be tilted inwards to make it easy to clean both the interior and exterior of your windows.
To do this, you’ll want to follow these steps:
Follow these instructions, and you’ll be able to properly clean and care for each and every crevice of your double-hung windows.
Both single-hung and double-hung windows have window sashes that slide vertically. On single hung windows, only the bottom sash can slide, while the top sash is fixed and static. On double hung windows, both sashes can slide as desired.
All Window World double-hung windows are installed by our factory trained installation team. This includes properly setting, leveling and caulking to ensure your new windows are a perfect fit. Find out more about our window installation process.
For double-hung windows, both sashes can slide and allow the window to open. To open the lower sash, simply unlock the sash and slide it upwards. To open the upper sash, you’ll need to unlock your lower sash, and gently lower the upper sash to your desired position.
To lock your double-hung window, it’s important to check the alignment of your locks. Make sure that your upper sash is pushed all the way up and your lower sash is pushed completely down so they’re fully sealed. This will allow your locks to be secured without any obstructions.
