Royal® Building Products’ Celect® Cellular Composite Siding has been on the market for over a decade, and has made a name for itself among homeowners for its beauty, versatility, and durability.

We recently added Celect® Cellular Composite Siding to our siding offerings and look forward to sharing it with customers across Southern Ontario, from Oakville to St. Catharines and everywhere in between!

Why Choose Celect® Cellular Composite Siding for Your Home

1. Appearance

Celect® Cellular Composite Siding is able to mimic the sought-after appearance of wood and is available in 15 different colours.

The interlocking joints, which are unique and proprietary to Royal® Building Products, guarantee a seamless finish with no visible nail heads or additional caulking.

2. Performance

Celect® Cellular Composite Siding’s gravity lock design is engineered to provide year-round resistance to buckling or waving, keeping boards secure and straight as they expand and contract with seasonal temperature changes. It’s even been tested to withstand hurricane-force winds in excess of 200km/h!

Celect® Cellular Composite Siding is also incredibly energy efficient, boasting R-values almost twice as high compared to wood or fiber cement.

3. Maintenance

One of the best things about Celect® Cellular Composite Siding is how easy it is to look after:

  • It’s built to repel mildew, mould, and insects with no repainting or re-caulking required.
  • The Kynar Aquatic® coating prevents fading caused by UV damage to keep colours vibrant.

Celect® Cellular Composite Siding also comes with a 25-year warranty on the finish.

These advantages and more make Celect® Cellular Composite Siding an exciting addition to our lineup. If you have questions or would like to discuss installing Celect® Cellular Composite Siding on your home, contact us today to schedule your free in-home consultation!
