Welcome to Duramax. Choose PVC garage wall panels as they don’t have wooden backers, unlike FRP and don’t rot, mold, absorb moisture or degrade. Post-installation PVC car wash wall panels last for 45 years, while FRP is susceptible to callbacks for repairs. The commercial wall panels made from 100% virgin vinyl require no glue, backers, or rivets for installation, unlike FRP. Save at least 40% on material costs and 50% on labor expenses by installing PVC waterproof garage wall panels that arrive in 2 weeks direct from the factory.
