RBS Celect Siding


Peek behind the eye-catching scenes.

The beauty of Celect® Cellular Exteriors 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.


The technology of our premium siding is as beautiful as its envy-inducing curb appeal.

Everything you imagine and work for goes into your home. So you have every reason to expect the premium siding you invest in to perform for you decade after decade.

If you're going to build premium siding with looks as amazing as we have, you better create ways to maintain and protect those looks. So that's exactly how we engineered Celect® Cellular Exteriors by Royal®.

Patented interlocking joint system

It's what makes seams virtually disappear and our premium siding so easy on the eyes. Plus it's simpler to install than fiber cement. The effect is aesthetically stunning and moisture repelling.

  • Keeps boards straight and true through the home’s natural expansion and contraction 
  • Eliminates caulked seams and energy loss 
  • No gaps, buckling or wavy lines

Gravity lock design

This ensures our premium siding exhibits no warping, 

buckling or shifting. The siding just sits there looking always magnificent and forever young.

  • Unique gravity lock design keeps courses locked tight 
  • Maintains structural integrity 
  • Wind resistance to over 130 mph

Kynar Aquatec® coating

  • Withstands all weather conditions and climates 
  • 25-year warranty on the finish 
  • Kynar Aquatec coating and cool-core technology reflect heat in the summer and contain it in the winter All of our trim, mouldings and mounts can be had in the 18 Kynar Aquatec-coated colors of Celect and are available for complementary mixing and matching

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.
