HardiePanel vertical panel siding is a fiber cement product. Designed for vertical siding, these panels are available in four different textures. CedarMill Texture (no groove), Sierra 8 (grooved 8 inches on center), Smooth and Stucco Texture. All four textures are available in 4 x 8 sheets with some textures available in 4 x 9 or 4 x 10 as special orders only. The CedarMill and Smooth panels are a perfect choice for board and batten applications. If you prefer the look of a grooved panel (like T1-11 siding pattern) see the Sierra 8 texture. These panels are great for residential and commercial applications. Great low maintenance choice versus real wood siding. Our Navajo White solid color is a beautiful off-white color with a touch of yellow in a rich satin finish. Batten strips, trim, and soffit materials can be finished in the same color or choose a complementary color of your choice. Custom colors are available, as all products are prefinished to order, made just for you.
