Windows are the primary source of temperature exchange in any building. Improper sealing allows climate-controlled air to escape and outside drafts to enter. Our glaziers install replacement insulated glass units (IGUs) to restore your interior climate and lower energy bills.
Advantages of Installing Insulated Glass
Insulated Glass Units (IGUs) offer year-round energy savings and comfort for your home. Here are some of the benefits of installing insulated glass:
-
Reflect heat in summer to reduce air conditioning costs
-
Minimize heat loss in winter for consistent indoor temperatures
-
Sealed with high-grade materials to prevent condensation
-
Available with gas-filled spacers for added insulation
Insulated Glass Replacement
Our glaziers specialize in insulated glass replacement, fitting new units directly into your existing frames—no full window replacement required. We serve homeowners across Maine, New Hampshire, and Massachusetts.
Insulated Glass Repair
Homes equipped with double-pane windows (a type of insulated glass) develop temperature regulation issues when a seal breaks. If condensation builds between panes or windows appear foggy, our glaziers provide insulated glass repair that restores clarity and performance.
