What is a thermal bridge and why is it so important to break it?

...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...

...thermal bridges: When one section of a wall conducts heat much quicker than another, we refer to it as a thermal bridge , and that can greatly reduce the overall R value of a wall. Virtually every thermal bridge in this wall assembly was identified and eliminated in the design phase. Thermal breaks in exterior insu...

How insulation works

...thermal bridge', and preventing it is known as a 'thermal break'. Heat loss through thermal bridging When we mentioned at the beginning that these factors can work in conjunction, that is because the cold surface that results from the high conduction through wall studs and other thermal bridges can absorb radia...

The easiest way to insulate walls from the exterior in older homes

...thermal bridges – wood does act as a thermal bridge, but not nearly as much as metal, and with engineered I-joists, at only 5/8ths of an inch, the conductivity of the wood isn’t a great concern and becomes even less so the deeper it is. Fiberglass thermal spacers or "Cascadia Clips" The purpose of fiberglass insula...

...thermal battery by storing and releasing heat , which helps balance temperatures in both summer and winter. Such quantities of heated thermal mass inside the building envelope also provides heat security in the event of a power outage, by slowly releasing its heat over the course of days. Raft slabs can be heated wit...

...thermal bridge , robbing you of your hard earned heat. In order to attain a modicum of energy efficiency, you would end up still having to build an entire additional structure to accommodate insulation, as well as install exterior cladding . So gone is that nice modern metallic look you were after as well as the very...

Excel II sheathing © BP Canada There are many products and techniques that can make for a great air barrier, but most importantly we need to prioritize it during every step of the entire building enclosure process. Think...

It also helps reduce the chance of interior moisture issues by raising the temperature of the first interior condensing surface, the concrete. Below is a thermal image of the basement descibed above with insulation on both sides. The effective ...
