Thermal bridges / Green Building & Sustainable Home Renovation Information & Advice

...thermal bridges A thermal bridge is a heat highway that bypasses your insulation. Materials like steel and aluminum transmit heat roughly 400 to 1,000 times faster than insulation. Even wood studs act as bridges, moving heat through a wall much faster than the insulation between them. And in homes with high humidity, y...

...thermal envelope is in terms of window quality. Having an extremely well-insulated wall is great, but if you blew the budget on insulation and had to put in low-quality windows, they become the weak link in the chain and you can effectively undo all your own efforts to reduce heat loss. So in the case of a super-insula...

...thermal bridging Thermal bridging around windows and doors results in loss of energy, cold spots, condensation points and potential wall damage. To demonstrate the importance of window and door placement relative to the wall's exterior, we ran some thermal transmission tests with the following results.    Images like t...

...Thermal bridges that will cause significant heat loss are not limited to just studs in a wall. They include discontinuities in the insulation, corner junctions, badly installed insulation (convective thermal bridges), concrete slab junctions at walls and balconies, service openings (structural thermal bridges), and 'pe...
