Our pre-finish process includes a proprietary paint which uses the purest metal oxide colorants extracted from rocks. These natural raw pigments don’t fade over time and pigments keep your siding vibrant while protecting it from destructive Ultraviolet sun rays that cause synthetic tints to fade quickly. 

Our fully automated pre-finish process begins by sanding and cleaning the substrate to ensure proper adhesion of the finish for a long term performance. Robotic sprayers provide consistent paint coverage by breaking down ​the finish into smaller particles allowing it to bond better for flawless coverage which cannot be duplicated with traditional onsite and flood coat applications. Before being chilled for packaging, the product is first sent through the oven to create a durable scratch resistant exterior siding product.

LP® SmartSide® products resist impacts of everyday bumps and hail damage. Be confident in choosing a performance-driven product that stands up to harsh weather. See how​ our siding resists hail damage better than fiber cement and vinyl.

NASA testing of LP® SmartSide® siding has also shown that it resists impacts better from baseballs, golf balls, river rocks, and marbles traveling at high speeds. Watch the impact video testing different siding products.

Our innovative packaging system reduces the risk of scuffing and scratching during the transportation and handling process. Our siding and shakes are packaged in 4-packs, trim in 2-packs and one piece corners are individually wrapped.

We believe in quality products that are sustainable and ecologically friendly. Our paints are water borne resulting in low V.O.C emissions and our semi-trucks are powered by compressed natural gas engines, reducing greenhouse gas emissions up to 20%.

The entire LP® SmartSide® Trim & Siding manufacturing process is also earth-friendly. In accordance with Sustainable Forestry Initiative® standards, they use wood from small, fast-growing trees for less waste and better resource usage. This process uses the entire log, with no urea-formaldehyde and low-emitting safe resins as a binder. Finally, the zinc-borate in LP's SmartGuard® manufacturing process is a naturally-occurring material.
