This clip-in system of rails and studs made of 100 percent recycled PVC is refreshingly easy to install. It's not meant for load-bearing walls, but the material's rot-proof, termite-proof qualities make it perfect for, say, finishing out a basement. No nails. Just screw the rails into place and snap in the studs.
The system costs about $5 per 8-foot stud.EcoStud, by Superior Polymer
