Benchmark proudly stocks STB-1 Structural Thermal Break Systems and TBF in Canada. Since these material are in stock we are capable of providing very fast turnaround on an expedited basis. As required, Benchmark also has the capacity to fabricate STB-1 washers and bushings in house.
High strength, structural grade thermal break material
Ideal for shear connections and other applications where high mechanical properties are required.
Available in 3 densities: TBF-150, TBF-200 and TBF-280
TBF features a specialized, rigid composition engineered for maximum thermal resistance. Engineered in multiple grades to accommodate specific load-bearing requirements, it provides a seamless thermal barrier for high-performance construction and cold storage environments.
STB-1 connections increase the overall effectiveness of the Thermal Break system they are used in conjunction with.,
