Exterior Windows and Door Upgrades


There are a number of options for upgrading the energy efficiency of your windows and exterior doors. From replacing the hardware on windows, to adding sweeps on doors. Much of the previously lost heat can be maintained in your home, as well as preventing cold air or drafts from entering.

At times the best choice is total window and frame replacement with new, high-performance ENERGY STAR® qualified windows or inserts. If the frames are still in good condition, inserts (i.e. new sash and glazing units) can be a good option, especially for homes with heritage status.

ENERGY STAR is a voluntary program created by the EPA that helps businesses and individuals reduce energy consumption to save money and protect the environment. To earn the ENERGY STAR label, windows and doors must meet rigorous energy performance levels. Qualified products must also have third-party certification based on testing in recognized laboratories.

First the insulating value or U-factor indicates how much heat or cold transfers through the window or door. The lower the U-factor, the more energy efficient the product is. Additionally. the solar heat gain coefficient (SHGC) measures a window’s ability to block the sun’s heat. The more solar heat it blocks, the lower the SHGC number. Where air conditioning is prevalent, ENERGY STAR requires a lower SHGC. Where heating is more prevalent, opt for a higher SHGC so the sun’s rays can stream in on cold winter days.
