High Performance Thermal Upgrades

Even though our standard features qualify us for Energy Star on every single window, we know that there are those that demand even better performance. For those that want to save even more on heating and cooling bills Walsh Tundra Windows and Doors offers these optional performance upgrades.

The U-Factor is the thermal performance rating determined by the National Fenestration Rating Council (NFRC) through strict testing to provide fair and accurate comparison of windows. Compare Walsh Tundra Double Hung window options to the Energy Star Standard.
