Product Overview

Sterling streamlines the process for designing and installing mass timber systems with standardized, scalable CLT components. Our 3-, 5-, and 7-ply TerraLam® CLT panels come in nominal lengths up to 18’ and widths up to 8’ and are pre-fabricated to suit your project. Sterling’s TerraLam CLT panels are certified to PRG 320 by ICC-ES and listed under ESR-5053. 

TerraLam CLT panels are manufactured in Phoenix, Illinois, and Lufkin, Texas with #2 or better southern yellow pine laminations in the major and minor directions. This fast-growing, sustainable species reaches maturity in approximately 20-25 years and is sourced from responsibly managed pine plantations in the southeast United States. 

TerraLam panels carry a Red List Free Declare® label through the International Living Future Institute, and our Environmental Product Declaration (Coming Nov 2022) will be available for life cycle assessment and carbon-optimized projects.

Standard, Repeatable Delivery

Sterling’s TerraLam CLT product line is an ideal floor, roof, and wall solution for repeatable, scalable building types and is compatible with a range of structural materials. Sterling streamlines the design, fabrication, and installation process for structural CLT by utilizing a standard-format approach.

Designing the majority of spans to our standard base sizes allows Sterling to deliver the most cost-effective system. This approach focuses on balancing standard and custom building blocks, making fabrication faster, logistics easier, and allowing CLT to compete with commodity building materials. We pre-fabricate the required panels to custom sizes, shapes, and openings using in-house CNC capability to suit your project’s design intent and engineering requirements.
