At Boral Bricks our products are the result of extensive research and input from architects, builders and designers from across the U.S. Thanks to their active participation, we remain on the forefront of architectural and design trends.
Boral Bricks come in a variety of rough and smooth textures, in colors that range from nearly white to deep burgundy brown. You can select solid colors, color ranges, bricks that are made to look antique, bricks that are sharp and crisp. Add colored mortars, brick shapes for architectural interest, and pavers to complete the picture. Boral gives you more possibilities because we give you more choice!
At Boral Bricks, our product development doesn't stop at making quality bricks, we make the color and texture you ask for. We offer over 150 different colors and textures of brick available and ready to be used for the entire house or to work with other materials such as stone and shake. We have products you just won't find anywhere else, creating a beautiful antique facade, or our genuine clay pavers with color that will never fade. What's more, we offer a full line of Boral Brick Shapes that build architectural detail and add character to your home.
Selecting natural Boral Bricks products provides environmental advantages for virtually any building project. Boral Bricks are composed of mineral elements that stand the test of time without harming the environment as they age. Boral Bricks are an ideal choice for architects and builders working to achieve the goals of sustainable design.
