Let’s see how LP SmartSide Trim & Siding vs. James Hardie Boards compare in some key areas:
James Hardie boards consist of Portland cement, sand, water and cellulose fibers, in addition to proprietary additives. LP SmartSide siding gets its superior durability from treated wood strands coated in resins, waxes and zinc borate for strength and impact resistance.
James Hardie boards come in 12-foot lengths, while LP SmartSide siding can be manufactured in 16-foot lengths that can result in fewer seams for improved aesthetics. LP SmartSide siding also looks more like traditional wood.
LP SmartSide siding may be less expensive than Hardie boards.
LP SmartSide siding is a more durable material than James Hardie boards because of its proprietary SmartGuard® manufacturing process. This process ensures that every strand of wood is treated with a carefully formulated mix of resins, waxes, and zinc borate, and finished with an overlay to offer complete protection against extreme heat, moisture, termites, and fungal decay.
