FRP panels are vulnerable to damage from excessive moisture and strong impacts. Instead, check out the PVC panels from Duramax that are extremely durable and long-lasting. They are ½” thick with a unique inner webbed truss design and can withstand attic insulation load efficiently. Further, PVC panels have a shelf life of 100 years, backed by a limited lifetime warranty. These panels remain unaffected by excessive moisture and do not rot, mold, crack, or peel off over the years. Trust Duramax, the PVC panel supplier, rather than FRP suppliers, to ensure long-lasting interiors. Call 213-652-7665 now!
