Hello,
I have a house with cellulose insulation from Xnvillan. The walls are about 46 cm. The goal of choosing wood fiber/cellulose insulation was to have a breathable living space. Wood is a very well-proven building material, so it still feels right and environmentally friendly. However, it seems that we've encountered problems with moisture not drying out in the upper parts of the walls.
Has anyone else experienced this?
