What real wood aspires to be.

Smart Technology

Built to quietly astound.

Celect doesn’t brag; it doesn't boast. It just sits back and amazes. It looks as handsome as natural wood, but that’s where the similarities end. Its interlocking joints keep moisture out and almost completely eliminate seams, which means it not only looks authentic, it’ll never warp, buckle or shift like wood...would.


Low Maintenance

Sorry fiber cement, this isn’t going to be pretty.

With Celect, you can forget about mold, fading, deterioration, scrubbing and messy maintenance crews. You can also forget about painting, repainting, caulking, re-caulking and delaminating like fiber cement is famous for. Celect is all about virtually maintenance-free great looks that never quit. Year after year, decade after decade.


High Sustainability

Great value. And R-value.

Celect is warmer in the winter, cooler in the summer and greener all year long. In addition to being completely re-usable and 100% recyclable, it provides an R-value that’s twice the thermal value of any other comparable material in the market. In other words, it’s as much of a renewable investment as it is a renewable material.


Customer Care

Keeping Maintenance to a Minimum

With Celect® Cellular Exteriors by Royal® there’s no need to worry about fading, mold, deteriorating, delaminating, painting, caulking or scrubbing. Our siding even resists dirt and dust so you rarely even have to think about cleaning it. All it takes is the occasional easy spray with a garden hose to keep it looking premium.
