Mold Resistant Rigid Foam Insulation

I plan to first install 2 inch xps rigid foam on the walls and build 2x4 stud walls next to the foam panels.

Mold resistant rigid foam insulation.

Cellulose insulation is constructed of ground paper which is an ideal food source for the growth of mold if it becomes wet. Foam building insulation in both spray foam and foam board products is resistant to mold growth but as we will explain here it is not absolutely mold roof and on occasion we do find mold growth on the surface of even closed cell foam in open celled foam rare and on th surface of eps and other foam insulating board products uncommon. It is denser than eps and provides more r value with a rating of 5 per inch of thickness. 0 56 in x 4 ft x 8 ft.
