Black Locust siding is one of the most durable wood materials that is naturally water and rot-resistant. Black Locust siding has low maintenance needs and offers exterior protection from rain and snow conditions. Black Locust siding provides extremely durable and long-lasting protection for the exterior of the building. Our architect’s guide to Black Locust siding will help build your knowledge as you seek the perfect cladding for your project. 

What is siding?

Siding is a material that can be manufactured from wood, cement board, aluminum, vinyl, or other synthetic materials. These materials are used to surface the exterior of a building or house. The siding protects the building against exposure to natural elements, prevents heat loss and heat gain, and helps visually unify the design. 

Best wood material for exterior siding: Black Locust siding  

Not all types of wood are suitable for exterior siding. Black Locust is a type of wood material that belongs in exteriors due to its longevity. The wood is naturally rot-resistant and has anti-fungal properties without the help of any toxic chemicals or additional surface treatments. Black Locust siding is a sustainable material that does not require oils, stains or sealants. Black Locust siding is recognized as a sustainable source when it comes to LEED, BREEAM, and FSC® requirements.

Wood Grade for Black Locust siding

Wood siding is generally rated on its appearance. For this reason, building codes do not govern the grading of sidings. Black Locust wood requires unique grading rules to ensure you get the best quality wood. Our many decades of history in the Black Locust Lumber industry have led us to develop our own grading rules. We follow our own Grading Guide that will enable you to choose the most suitable Black Locust Lumber for your architecture project needs.

Wood siding has been recognized by green building rating systems as a go-to material with a better impact on the environment than traditional siding materials. The overall emissions during manufacturing are on the lower end of the spectrum.

The maintenance requirements over time are low when left natural and the potential for recycling is at its top when choosing Black Locust lumber as your siding material.
