In a wall assembly a thermal bridge is when:
WebA thermal break occurs when an insulator interrupts the thermal conductivity in a material. “Thermal bridging” is the pathway in which heat travels out of your home, a weak point or cold spot in the thermal envelope. Like the stud in a wall. WebFeb 4, 2024 · What are Thermal Bridges? A thermal bridge happens when there is a break in the building’s envelope. Typical spots for thermal bridges are at the junctions between the wall, floor or roof, around holes for cables and pipes, and near windows and doors. ...
