What is a thermal bridge?

[Knecke]

Hello, can someone kindly explain to me what a köldbrygga is? and if necessary, how to avoid it?

For example, a timber stud that is in unbroken contact with cold outside air, via an outer panel or similar, and an interior wall can be considered a thermal bridge. That is, cold is conducted through this.

A common way to avoid cold bridges in, for example, walls is to install vertical studs with insulation between them and then a horizontal stud (45x45 mm) with insulation between. The cold bridges you get now are much smaller, only where the vertical and horizontal studs overlap. Even better is if you can build what's called a shell wall - in principle, you build two walls (insulated) and fill the gap in between with more insulation, completely without cold bridges.

It is worth noting that the material of the bridge plays a big role in how much energy it transmits. Concrete conducts heat/cold about 15 times better than wood. Iron (in sheets, reinforcement, etc.) conducts approximately 35 times better than concrete.

Even a relatively small thermal bridge consisting of sheet metal can conduct large amounts of energy.
