Roseburg DuraTemp® siding has a natural textured appearance. Its surface is 100% clear and free of patches and repairs. It’s easy to paint, and can withstand exposure to the elements. Duratemp® is manufactured with a strong plywood veneer inner core that is made of western softwood veneer and a fully water resistant (NAUF) phenolic resin. The surface is a tough hardboard face that won’t split, crack or check — even with rough treatment. The plywood core is easy to handle and install yet stronger than most other siding products. Unlike vinyl and cement siding, DuraTemp ® Siding is made from real wood, an environmentally friendly renewable resource.
