Royal® Building Products, a Westlake company and leading manufacturer of exterior building products, has announced the launch of Celect® Canvas Cellular Siding, an unpainted version of its industry-leading cellular composite siding.

Celect Canvas features the same woodgrain aesthetics and low-maintenance benefits of the prefinished cellular siding offering, plus the ability to customize the color using thousands of exterior vinyl-safe paint shades that fall within the recommended light reflectance rating of 50 and above.

Celect Canvas is available across all of Celect’s profiles, including 7” Clapboard, Board & Batten, and 7” Shake. All Celect Cellular Siding offerings feature a patented interlocking seam design, which keeps moisture out and virtually eliminates seams.

“Celect Canvas unpainted siding has been a long-requested addition to our portfolio of Celect Cellular Composite Siding, which is unmatched in beauty and durability,” said Steve Booz, vice president, marketing, Royal Building Products. “We are excited to give designers, builders and homeowners the ability to customize their exterior color palette, without compromising on performance.”

Celect Canvas Cellular Siding also includes a Limited Lifetime Warranty. To learn more and get started using Celect Canvas, visit
