I am doing a basement project and trying to keep wood/organic products out of the wall to prevent potential wood rot or mold. There are metal studs in place, but these are not good for mounting trim work or cabinets. I am curious if composite decking, mounted horizontally between the studs, would be effective as a way to mount cabinets and trim once the drywall has been installed? Is there any better technique?
You should use backing plate for metal studs, but they could be difficult to find for diyer. Check clarkdietriech website for details:
You might also order similar thing from custom sheet metal shop.
