Combines the authentic look of cedar shingles with the high performance of poly-ash.

During the 2022 International Builders’ Show (IBS), Westlake Royal Building Products unveils a new profile—5/8” Lap Siding—to its line of TruExterior poly-ash siding. Developed in response to growing demand, the profile combines the coveted look and shadow lines of traditional lap siding with the high performance of TruExterior’s poly-ash material. It has a true 5/8” butt, a sought-after profile that mimics real cedar, and comes in 16-foot lengths.

“We’ve been getting requests for a lap siding profile for some time, particularly from building pros in the Southeast. Our new 5/8” Lap Siding answers that call, expertly mimicking the thickness and shadow lines of cedar in a way no other man-made product has been able to accomplish,” said John Gerhardt, director, product marketing for Westlake Royal Trim. “Along with its remarkable authenticity, our 5/8” Lap Siding delivers high performance that ensures low maintenance, long-term durability, and enduring beauty.”

Like all TruExterior Siding & Trim profiles, 5/8” Lap is made of poly-ash, a proprietary blend of polymers and fly ash that provides for a high level of dimensional stability, and durability for resistance to warping, cracking and splitting. As a result, the siding requires no sealing of ends or cuts in the field, it can be used for ground-contact applications, and it can be painted any color, including dark hues.
