The Mastic® Brand Introduces New Weathered Tones™ Siding Color Palette for Cedar-Inspired Style

Enhanced color technology delivers the realistic, natural look of wood with the durability and low maintenance homeowners expect

CARY, N.C.--(BUSINESS WIRE)--Cornerstone Building Brands, a leading North American manufacturer of exterior building products, today announced the launch of Mastic^® Cedar Discovery^® Weathered Tones^™, an enhanced collection of variegated shake and shingle siding colors inspired by the natural beauty, depth and character of weathered cedar. The launch reflects the Mastic brand’s continued commitment to inspire homeowners to achieve elevated exterior design through innovation and authentic aesthetics.

The Weathered Tones color palette introduces six rich, dimensional colors that capture the variation and character found in real wood cedar shakes while delivering the low-maintenance performance advantages of polypropylene siding. Inspired by coastal and nature-driven design trends, the collection provides homeowners, remodelers and builders with the opportunity to create warm toned exteriors that stand apart.

"Mastic Cedar Discovery siding has long been a trusted choice for homeowners seeking the beauty of real cedar without the ongoing maintenance," said Zach Duggan, director of product management, siding and accessories. "With Weathered Tones^™, we've taken that promise even further by introducing enhanced color depth, true-to-life wood-inspired character and a curated palette designed to reflect the way homeowners want their homes to look today. These colors were developed to work beautifully with our broader exterior portfolio, including PVC trim, color-matched vinyl accessories, shutters and soffit systems, making it easier for homeowners to create a cohesive, professionally finished exterior from a single trusted manufacturer."

Cedar-Inspired Beauty and Shades

The new collection is the result of an innovative, enhanced color process that provides richer variation and greater dimension than ever for a realistic cedar appearance across three Cedar Discovery profiles. The collection includes these new shades:

• Weathered Cedar – A blend of warm natural brown wood tones.
• Iron Harbor – A deep, sophisticated gray with layered coastal tones and subtle weathering.
• Harvestwood – Rich golden-brown hues that capture the warmth and charm of freshly milled cedar.
• Saltstone – A soft mix of cool grays inspired by coastal landscapes and naturally faded cedar.
• Barkwood Brown – A dark, grounded brown tone with natural variation.
• Emberwood – A warm brown infused with subtle reddish undertones.

Available in Double 9” Hand-Split Shake, Double 7” Perfection Shingle and Triple 5” Perfection Shingle profiles, the collection offers design flexibility for both whole-home applications and architectural accents.

A Complete – and Customizable - Exterior Solution
