TerraLam is based on cross-laminated timber technology, where layers of wood are bonded perpendicularly. This construction significantly enhances the strength and dimensional stability while minimizing the wood’s tendency to expand or contract under changing environmental conditions. This also ensures uniform load distribution, making for highly reliable use under heavy and dynamic load applications.
The wood used in TerraLam CLT mats is exclusively southern pine, a softwood known for its exceptional strength-to-weight ratio and reliability. Our wood is domestically sourced from trusted suppliers, ensuring consistent quality. Only Grade 2 or better lumber is selected. Each plank is kiln-dried, tested for precise moisture levels, and checked for straightness to meet our rigorous production standards.
Sterling maintains SFI Chain of Custody Certification. This certification mandates that at least 70% of lumber that we use is harvested sustainably. From the forest to the mill and into our warehouse, we follow a strict chain of custody to deliver the best product for your project while protecting our planet. By choosing our SFI certified wood, you’re not only ensuring quality but also making a responsible choice for the environment.
Sterling adheres to the Environmental Product Declaration standards with the lifecycle of TerraLam mats documented through an APD that is registered through EPD Hub in accordance with EN 15804+A2:2019 and ISO 14025. HUB-0174 covers the Raw Materials, Transport, Manufacturing, Assembly, End of Life, and Reuse of the product.
Dowels help reinforce the mats mechanically. By securing the layers together, the dowels enhance the mat’s ability to withstand extreme stress without compromising its durability or usability. The dowels are made of red oak due to its unique properties, offering the perfect combination of strength, flexibility, and resilience. And the precise placement of dowels ensures consistent quality and performance, as they mechanically reinforce the layers, creating a unified structure capable of handling high shear forces.
A treatment is also available to provide deep, lasting protection in challenging environments. This treatment involves fully immersing the mats in a carefully formulated borate solution, allowing the protective agents to soak into the fiber of the wood. The borate solution works by creating a barrier throughout the wood, making the mat inhospitable to fungal growth. This internal protection is particularly critical for environments where the mats may be exposed to persistent humidity, or extreme temperature fluctuations.
