Audio By Carbonatix

HOUSTON--(BUSINESS WIRE)--Feb 18, 2026--

Westlake Royal Building Products ™ (“Westlake Royal”), a Westlake company (NYSE: WLK), today announced the launch of Vertälla™, a striking, vertical accent panel, for its Royal ® and Exterior Portfolio ® vinyl siding lines. With a modern vertical profile and architectural depth, Vertälla delivers a fresh exterior aesthetic that sets it apart from traditional vinyl siding.

Intended strictly as an accent panel rather than full-home coverage, Vertälla elevates curb appeal by creating intentional contrast and visual interest. Its clean vertical lines are ideal for highlighting architectural focal points, allowing designers and builders to add dimension without overwhelming the overall facade and meet demand for multi-textured exteriors.

“With Vertälla, our goal was to deliver something truly different — an accent panel that brings architectural drama and modern character to vinyl siding in a way the category hasn’t seen before,” said Steve Booz, vice president of marketing at Westlake Royal Building Products. “Designed for intentional use, it offers pros and homeowners a new way to make a statement without compromising the performance and ease they expect from vinyl.”

For Royal and Exterior Portfolio vinyl siding lines, Vertälla will be available in 10 light, medium and dark colors, ranging from bold, modern hues to versatile neutrals. By pairing a distinctive vertical accent profile with a thoughtfully curated color palette, Vertälla expands creative possibilities for residential exteriors.
