Where Black goes bold and Gray & Black plays with contrast, solid Gray is the most versatile finish in the lineup — a clean, uniform cool-gray tone that complements virtually any architectural style without competing with it. Pairs naturally with white trim, warm wood accents, dark stone, concrete, and modern metal detailing. Built with advanced co-extrusion technology and a polyethylene-based waterproof film, these panels are engineered to hold their finish through years of outdoor exposure. No fading, no warping, no maintenance — just clean, professional cladding that holds up in any climate. Order a sample first to confirm the tone works in your space. Lighting affects how composite colors appear — seeing it in person before committing to full boxes is always the right call. Built for Outdoor Performance Engineered from high-impact Wood Polymer Composite (WPC), these panels are designed specifically to handle outdoor environments. UV and sun resistant — color holds without fading Moisture, mold, and mildew resistant Impact and crack resistant Won't warp, rot, or splinter like natural wood Extreme temperature tested from -30°F to +130°F No sanding, staining, or repainting required — ever The Gray Difference Gray is the most neutral and adaptable finish in the Highlander Home® exterior slat panel range. The uniform cool-gray tone reads modern without being aggressive, giving walls texture and character without demanding that the surrounding palette shift to accommodate it.

How does Gray differ from Gray & Black?Gray is a solid, uniform cool-gray tone with no accent color. Gray & Black has the same gray base but adds bold black accent slats through each panel. Gray is more understated and versatile; Gray & Black has more contrast and visual drama. Are the panels truly weatherproof?Yes. UV, moisture, mold, and impact resistant. Temperature tested -30°F to +130°F. What does the lug system do?The lugs on the back of each board create a natural air gap between the panel and the wall. This ventilation channel helps manage moisture and temperature behind the cladding. Can I install on a ceiling?Yes — drive fasteners into solid framing for overhead installations. Do the panels need sealing or painting?No. Pre-finished composite. Clean with water and a soft brush as needed. Is free shipping included?Yes — free shipping within the contiguous United States. Do you have a showroom?Yes — 10926 Woodside Ave Suite A, Santee, CA 92071. Monday–Friday, 8am–4pm.
