THERMAL BRIDGING - SlideShare

WebThermal bridging is when a particularly conductive (or poorly insulating) material allows heat flow across a thermal barrier. Physics dictates that hot wants to go to cold and a thermal bridge is a perfect invitation. The best analogy is to think studs within an insulated wall. WebApr 10, 2024 · Thermal Bridging Construction assemblies are very rarely monolithic. Rather, they require different materials that are assembled to make up the overall construction. In typical situations, the framing can account for 20-30 percent of the area of any given exterior wall with only about 70-80 percent of the wall area actually containing insulation. port link international services pvt ltd
