The Royal Ridgeback Reinforced Siding System from Royal Building Products offers the look of fiber cement without the maintenance. Manufactured from recycled PVC with a backing to enhance rigidity and resist impact, the panel doesn’t require painting or caulking. The siding mimics the look of benchmark solid-wood clapboard with classic 7" facing wood texture. Air channels help protect against condensation, rot, mold, and mildew. The company’s Windlok 250 system withstands 250-mile-per-hour winds. Eight standard (white, linen, vintage cream, wicker, Harvard slate, heather, sand, and soft maple) and six optional colors are available, all with Dura Color Protection.
