Managing moisture. Most solid walls are vapour permeable, which means that that moisture can pass through them. Therefore you need to make sure that by adding insulation you don’t create an ...

If you fail to have vapor barrier, there is less likelihood of moisture issues within the wall structure, but more likelihood of moisture issues inside due to moisture diffusing into the space through ...

1 - walls with internal thermal insulation and vapour barrier 1.1 - Concrete veil covered with ITI (EPS) with vapour barrier in winter Table 1 - Calculation note for a concrete shell covered with ITI ...

The internal temperature of the cold storage is generally -30℃~-10℃, which is very different from the outside temperature, so it is easy to form condensation water. Therefore, the envelope structure ...
