Timber buildings are healthier for the environment because wood materials store carbon throughout the life cycle of the building, instead of releasing it into the atmosphere to form carbon dioxide (CO2).

Building with forest products typically creates fewer emissions during the harvesting/extraction, manufacturing, and transportation cycle than other material types used in construction. With roughly 75% of carbon sequestered in a mass timber building being stored in floor and roof slabs, CLT in lateral applications is an excellent pathway to reducing the construction industry’s carbon footprint while leveraging the strength of engineered wood products.

CLT can play a multitude of roles in a structural system, either alongside steel and concrete in hybrid structures, or replacing them entirely: both are pathways to minimizing carbon impact in new construction. TerraLam CLT is a cost-competitive and user-friendly option that can bring structural strength and biophilic beauty into buildings of all budgets, sizes, and occupancy types.

TerraLam® CLT panels are built from Southern yellow pine, a fast-growing and structurally efficient softwood species native to the United States that has been an integral part of American building tradition for centuries. Sterling sources high-quality pine lumber from partners in the southeastern United States who are committed to renewable growing and harvesting practices. Through domestic and responsible sourcing, Sterling supports woodland economies. TerraLam panels can be SFI certified upon request or FSC certified at a premium.

Our raw material order volume and strategic plant location also allows lumber to be delivered directly by rail to our manufacturing facility in Phoenix, IL. Using the rail network to transport large volumes of raw materials and finished CLT panels is a strategic way to reduce greenhouse gas emissions from the movement of freight.

Material Health


Sterling TerraLam panels are Declare® certified by the International Living Future Institute to be Red List Free. The Declare product database contains data on ingredient lists and manufacturing practices that are voluntarily submitted by manufacturers who are committed to transparency and healthier buildings. 

EPD/Life Cycle Data

Our Environmental Product Declaration (EPD) is available for AEC teams to measure their sustainability through whole-building life cycle assessment (LCA). EPDs are third-party verified reports detailing the environmental impacts of our products through their lifetime. We can also offer LCA support upon request.

Living building and LEED

TerraLam panels are eligible for credits in the Materials Petal of the Living Building Challenge, as well as sourcing and material health areas in buildings in pursuit of LEED v4 certification. Contact our team to learn how TerraLam can support your sustainable design goals.
