Double Pane Glass Repair & Replacement
Double pane glass, also called dual pane or insulated glass, features two sheets of glass separated by a sealed air or gas-filled space. This design provides superior insulation, noise reduction, and energy efficiency compared to single pane windows. Double pane glass is the standard in modern home construction throughout the DMV area and is the most popular upgrade for older homes seeking better energy performance.

Repair Information
Double pane glass repair typically involves replacing the entire insulated glass unit (IGU) while keeping the existing window frame. When the seal fails between the panes, moisture enters the gap and creates a foggy or hazy appearance. Our technicians measure the exact dimensions, order a precision-cut replacement IGU, and install it with new seals. For cracked or broken double pane glass, we can often source replacement units within 24 to 48 hours.
Double Pane Glass & Energy Performance
Double pane glass provides an R-value of 1.5 to 3.0 depending on the gas fill and coating options. In the DMV climate with hot humid summers and cold winters, double pane windows work year-round to keep conditioned air inside and weather outside. Low-E coatings on double pane glass can further reduce UV transmission by up to 75 percent, protecting your furniture and flooring from sun damage while keeping your home cooler in summer.
