Get The Best In Austin Window Replacement

A great window replacement experience starts with a well-designed product. But what features make for a good vinyl double hung window?

Here are the six key elements to keep in mind when shopping for double-hung windows in Austin, TX:


One indication of a well-designed double hung is when its sashes interlock with each other and the window frame. This can form a strong barrier against air leakage.

Reinforced Meeting Rails

For better and more effective insulating properties, look for non-metal reinforcement. Non-metal beats out metal rails because they are five times stronger than steel and have hundreds of times the insulation value than aluminum. This level of quality can significantly minimize cold transfer.

Foam Filled Frame And Sashes

When the windows are made of vinyl, they instantly have the edge over other window types because of their multi-chambered construction, which is not found in other alternative materials. Foam insulation is injected into the spaces to enable vinyl windows to provide maximum energy efficiency.


The amount and type of weather stripping added into your double hung windows can determine how well they perform in preventing energy loss. We recommend choosing windows with multiple weather-stripping around their sashes.

Welded Corners

Most window types are mechanically joined in the corners which tend to loosen over time allowing a significant amount of air to leak. Look for double hung windows with corner joints welded together. This will make it almost impossible for air to get out of your home, plus it will give your windows a more professional and clean finish.

Insulated Glass

The type of glass you use in your windows can have a huge impact in their performance. To take full advantage of their energy saving properties, you can choose from our many variations of insulated glass packages to meet your energy needs.
