State of the Art Manufacturing

Harvey is constantly improving upon our home windows and house door products which are manufactured right here in the Northeast. We recently constructed a state-of-the-art manufacturing facility featuring a redesigned layout, additional automation, an in-house testing lab, and a dedicated recycling area to help preserve our natural resources.

This new plant, located in Londonderry, NH, replaces our Manchester, NH facility—and at 375,000 Square Feet, doubles it in size! Although we have continued to expand, we pride ourselves on manufacturing our products in the Northeast.

Low E Thermal Efficient Windows

Clear glass windows prevent the least heat loss while windows with Low-E are much more thermally efficient. The best performing windows are those using Low-E/Argon glazing. Our Tribute double hung windows come with a double Low-E/Argon glass window pane package that exceeds .3 U Factor requirement. And the optional Tribute HP TG 2X Low-E/Krypton SunClean™ & SPF™ w/Grid ENERGY STAR® package brings the U Factor down to an incredible .2. Learn more about energy efficient windows now. Enjoy the energy saving performance of Harvey Replacement Windows.
