Insulated Glass Units (IGUs) are double or triple-pane windows designed to provide superior thermal performance and energy efficiency. Unlike single-pane glass, IGUs consist of two or more glass panes separated by a spacer and sealed together, creating an insulating air or gas-filled gap. This design helps reduce heat transfer, maintain indoor comfort, and minimize energy costs by acting as a barrier between your home and the outside environment. When an IGU is damaged, it compromises the seal, reducing the window’s insulating properties and often causing condensation, fogging, or visible distortion within the panes.

When replacing an IGU, it is essential to replace the entire unit rather than just the damaged pane. The reason for this is that the panes are sealed together as a single unit, and breaking that seal to replace just one pane would eliminate the insulating properties. Additionally, a broken or cracked pane often results in a loss of gas fill (such as argon), which diminishes the window's energy efficiency. By replacing the entire IGU, we ensure that the window retains its insulating capabilities, restoring both performance and clarity.​​
