As required, Benchmark also has the capacity to fabricate Thermal Break washers and Thermal Break Bushings in house.
STB-1 Structural Thermal Break
Hi strength, structural grade thermal break material
Ideal for shear connections and other applications where high mechanical properties are required.
- Available with Thermal Washers and Bushings
- In stock in 1/4", 1/2", 3/4", 1" and 2" Thickness
TBF High Density Thermal Break Foam
Available in 4 different densities TBF-150, TBF-200, TBF-280 and TBF-310
TBF Thermal Break Foam is a high density, closed cell rigid polyurethane foam used as an effective thermal break for a variety of building envelope and cold storage applications. It is manufactured in several densities to support a range of load conditions.
- Available with Thermal Washers and Bushings
- In stock in 1/2", 3/4", 1", 2" and 3" Thickness
Thermal Break Washers and Bushings
Structural Thermal Break connections increase the overall effectiveness of the Thermal Break system they are used in conjunction with.,
STB-1 Thermal Break washers and bushings can be used on the warm face of the structure, and including a thermal break at the bolt connection will reduce heat loss an additional 4% per bolt, depending on the wall assembly connection. Without these thermal break solutions, condensation can occur on the bolt heads which can develop into damp and mold issues.
