CrossLam CLT

Cross Laminated Timber (CLT)

Cross Laminated Timber (CrossLam® CLT), is a multi-layer mass timber product spanning two directions with precision accuracy resulting in a secure, airtight building solution for any floor, wall, roof, or core. Serving as a significantly lighter replacement for concrete, CrossLam CLT is carbon negative and uses wood exclusively from sustainably managed forests. CrossLam CLT opens the door to a new, ecological way to construct mass timber buildings of the twenty-first century.

After more than 50 years of innovation, we’re proud of the hundreds projects that contain Structurlam’s mass timber components.


Strengths of the CrossLam® CLT System

Included in the Canadian Supplement to the National Building Code (NBC), CrossLam® CLT is being used in schools, health care facilities, public buildings, commercial buildings, and multi-family housing across the country for its durability, reduced carbon footprint, and ready to assemble system.

One of the biggest benefits of mass timber panels as compared to other types of structures is the ability to prefabricate the entire project. This saves precious time and money on-site because the installation process becomes more efficient.


CrossLam® CLT is manufactured with CNC machines in a factory environment where close tolerances and rigorous quality control are easily achieved.

Standardized Sizing

Achieving building efficiencies can be greatly enhanced if the mass timber project is designed from the beginning with standard CrossLam® CLT panel sizes.

Structural Strength + Stability

The CrossLam® CLT system is structurally comparable to steel and concrete but lighter.

Mass timber projects utilizing our Cross Laminated Timber system can have smaller, less expensive foundations, and are ideally suited for poor soil conditions.

Cost Efficiency

Mass timber projects that leverage the CrossLam® CLT system from design to erection are cost-effective alternatives to traditional steel and concrete. By using our CLT system, a compressed construction schedule is realized and overall project costs are reduced.

Reduced Construction Time

In comparison to concrete structures, CrossLam® CLT projects are installed in a shorter period of time due to the nature of prefabrication and dry materials. Mass timber components arrive on-site as a kit of parts, require less storage, and can be shipped for just-in-time scheduling.

CrossLamCLT is carbon negative and uses wood exclusively from sustainably managed forests.

Light Environmental Impact

Life Cycle Assessment studies show that mass timber has a lighter overall environmental footprint than other building materials. CrossLam® CLT stores carbon and produces fewer greenhouse gas emissions during manufacture. The wood fibre used in our Cross Laminated Timber is traceable from certified forests to the consumer.

Code Acceptance

In Canada, CLT is now part of the Supplement to the National Building Code of Canada (NBC). The CSA-O86 Technical Committee has approved the adoption of CLT in the 2016 Supplement to the CSA-O86.


CrossLam® CLT is certified to meet the requirements of the Standard for Performance Rated CLT ANSI/APA PRG 320 and the APA Product Report PR-L314C. These standards outline the requirements and test methods for qualification and quality assurance for CLT and are the same across North America.
