Is there any interior paneling that anyone recommends? I am personally tired of replacing paneling due to swelling because of moisture and humidity. I fear that even after I get the leaks resolved I will still be fighting this never ending battle. I would love to find a nice looking PVC or any other waterproof paneling that I could install and be done with this rot. I have found a few bits of PVC but it is in strips at a max of 12" wide and my walls are 16" supports. I could install mounting strips across the back to support it but if I am putting wood to support this, that will just rot later.
