Hi there all,
I am bricking/blocking up an old doorway in an external wall, as part of renovation works.
The building is about 80 years old and the cavity is max 45mm.
My question is, what is the best form of cavity insulation to use, while making sure that moisture is not transmitted through?
Kind regards.
