I have heard a lot about thermal bridges. What is the biggest disadvantage of them? What can happen if you indeed have thermal bridges? It's only on exterior walls that you have thermal bridges, right? Does it make the wall colder? More moisture? Or what???
A thermal bridge is an uninsulated or poorly insulated area. In other words, a poorly insulated wall which in turn results in a worse U-value. This in turn requires more energy to heat up and possibly poor comfort with cold drafts in those areas.
The worst thing about a thermal bridge is that it actually causes a local cooling that, in the worst case, creates a breeding ground for mold growth. The indoor air contains such a high moisture content that the moisture condenses against the thermal bridge. It's like pouring water on the wall, floor, ceiling, or wherever the thermal bridge is located.
Thermal bridges can occur anywhere one side is cold and the other is heated. For example, in a ridge roof where load-bearing beams are not alternated with insulation but extend from the outer roof to the inner roof, the same applies to walls.
I have 45mm insulation in front of the stud before the outer wall comes....not much but is it ok???Consensus said:
It's a tiled bathroom.....so there's a vapor barrier and rubber, then tiles on it, so there can't really be any direct moisture inside from the house anyway....superturbo said:
