About this update from Core Natural Resources, Inc.

New lookbook and visualization tool help homeowners confidently coordinate home exteriors with products from the Ply Gem Portfolio aligned with current design trends CARY, N.C.,, June 25, 2026 --( BUSINESS WIRE )--Cornerstone Building Brands, a leading manufacturer of exterior building products in North America, has partnered with designer and host of HGTV's Fixer to Fabulous Jenny Marrs to introduce 12 curated palettes featuring products from the Ply Gem portfolio of brands: Ply Gem Windows and Doors, Mastic Siding and Ply Gem accessories. Designed to help homeowners simplify exterior design decisions and create more cohesive, confident curb appeal, the palettes bring together coordinated siding, windows, stone, trim and accent color combinations inspired by today's shift toward warm, grounded and nature-influenced design. As part of the palette launch, Cornerstone Building Brands also introduced the Jenny Marrs Curated Exterior Palettes lookbook , which gives homeowners a deeper look into each palette through curated product pairings, design inspiration, trend insights and guidance from Marrs on how to bring each look to life. "Designing an exterior can feel overwhelming when there are so many options to choose from," said Jenny Marrs. "We wanted to create palettes that make the process feel more approachable by showing homeowners how colors and materials can naturally work together." To further support the design experience, homeowners can also explore the palettes using the Mastic Home Design Visualizer , where they can test combinations on their own home or sample projects before making final decisions. "With the Jenny Marrs Curated Exterior Palettes integrated into the Mastic Home Design Visualizer, homeowners can bring the signature style they've seen from Jenny on Fixer to Fabulous directly into their own homes," said Susan Selle, chief marketing officer at Cornerstone Building Brands. "The tool removes the guesswork by allowing users to confidently explore colors, textures and product pairings in real time, helping them make more informed decisions and achieve a cohesive exterior design with ease." The collection highlights a range of exterior styles and moods, from classic black-and-white contrast to calming greens, soft coastal tones, warm neutrals and dramatic modern palettes. Each design includes coordinated product and color pairings intended to help homeowners visualize a complete, cohesive exterior — featuring products from Cornerstone Building Brands' Ply Gem portfolio of exterior building product brands, including Ply Gem Windows & Doors, Mastic Vinyl Siding and complementary accents and accessories.
