Peek behind the eye-catching scenes.

The beauty of Celect® Cellular Composite Siding by Royal® is the range of powerful feelings it elicits: the pride in sheathing your home in the gorgeous armor it deserves; the peace of mind in possessing woodlike beauty impervious to mold, caulking, heat and cold; and the supreme confidence that you’ll never need another home exterior.

Celect can’t help looking as beautiful as it does because that’s the way it's engineered. Our cellular materials faithfully emulate the rich, evocative appearance of wood. Our patented interlocking joint system makes unsightly seams virtually disappear. And our gravity lock design ensures against less-than-beautiful buckling and warping. The results? Truly premium siding looks and devastatingly handsome horizontal and vertical integrity. 

Embrace the premium home exterior that takes care of you.

For homeowners with Celect® Cellular Composite Siding by Royal®, the good life is having the most curb-appealing exterior—and the most carefree maintenance—on the block. Actually, it’s a great life. A wonderful, mold-repelling, mildew-defying, insect-rejecting life.

Long-term maintenance takes its toll in time, inconvenience and cost. But not with Celect. It won’t delaminate because its cellular materials won’t let it. Unlike fiber cement, it eliminates the need for painting, repainting, caulking and re-caulking. Plus its deep, rich Kynar Aquatec®–coated colors never fade.

  • Stands up to impact even under the harshest weather conditions 
  • Kynar Aquatec coating withstands all weather conditions and climates 
  • Backed by a 25-year color-protection warranty
