• Why Celect is Better - Performance - Hero

    The best premium siding doesn’t just lie there. It performs.

  • Performance

    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 Composite Siding 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 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 210 mph
  • Kynar Aquatec® coating

    You can thank our celebrated coating for a rich, deep palette of colors that are here to stay. It provides superior UV resistance and reflects energy back into the atmosphere—making heating and air conditioning less energy demanding.

    • 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 15 Kynar Aquatec-coated colors of Celect and are available for complementary mixing and matching
