Concrete is porous and allows moisture and air to move through it easily.
Cold room walls.
Bathrooms are a readily understandable example of this phenomenon.
Drafts and cold walls mean that somehow cold air is getting in and it s usually through the windows or electrical outlets.
Ideally you should use a basement corner of the house to take advantage of two cold concrete walls.
Cold room panels can be manufactured 60 mm 80 mm 100mm 120mm 150 mm and 200 mm thickness.
Framing a cold storage room.
Cold room panels are composed of 3 layers the external and internal is galvanized sheet or aluminum sheets and core materials used high density polyurethane foam.
Surface material of wall and ceiling panel is made of polyester painted galvanized steel sheet painted ral 9002.
Panels are produced with 116 cm width and any desired length up to 13 5 meter.
Since it s part of your basement the cold room will have a concrete floor and the walls will be unfinished.
For me it was impossible to use a basement corner so i will use only one wall to cool this storage room.
