CertainTeed Announces Availability of New  CERTAplank™ Reinforced Siding


Innovative cladding with the wide, flat face of hardboard siding at a lower total cost to install and maintain

**UPDATE July 2020**

CertainTeed is temporarily pausing the sale of CERTAplank Single 7-inch Reinforced Siding, due to some mixed feedback about the cosmetic appearance of the lap after installation. CERTAplank is an important innovation in our siding portfolio and manufacturing will resume as soon as modifications meet CertainTeed’s high quality standards. For more information, building professionals and homeowners can contact their sales territory manager or customer service at 800-233-8990.


CertainTeed, a leading North American brand of sustainable building materials, today announced its new reinforced siding innovation, CERTAplank™. Made in the U.S. and available nationwide, the wide-faced, durable vinyl cladding combines modern hardboard looks with a lightweight 7-inch, slim but rigid profile that can be installed quickly and safely, and requires virtually no upkeep.

“CERTAplank is the result of many years of research and product development,” said Kara Radcliffe, director of vinyl siding product management for CertainTeed. “Fiber cement and wood planks are cumbersome and heavy, and they require special tools, extra crew and safety gear to install. CERTAplank resolves these installation issues while delivering a beautiful, flat-face hardboard look. We’re very excited to introduce it to building professionals and homeowners alike.”

Because CERTAplank is lighter weight and more flexible than fiber cement or natural wood siding, contractors can hand unload CERTAplank without any special equipment, storage or stacking requirements. Panels will not crack or chip, and there are no OSHA restrictions on handling or cutting material outdoors. Any standard ¾-inch siding accessories can be used as trim, including standard new construction window J-Channel.

In addition, the durable foam backer and panels both meet the code specified Class A flame spread rating for building materials, when tested in accordance to ASTM E-84. Moisture-resistant panels feature a post-formed factory lock, heavy-duty thickness, and rolled-over reinforced nail hem, which has been designed to withstand hurricane force winds.

“With our proprietary STUDfinder™ and self-leveling tight lock features, a single person can easily install the CERTAplank panels. There are no special saws, masks, nail guns, caulk guns, paint or leveling tools to purchase, and upkeep is inexpensive for homeowners because the vinyl surface is easily cleaned with soap and water,” Radcliffe added. “Plus, because there is no need for caulking or painting touch-ups, long-term maintenance costs are significantly reduced.”

Now available nationwide, CERTAplank is offered in 18 colors with a woodgrain finish. For more information, visit, contact your local CertainTeed distributor or call 1-800-233-8990.
