Window opening thermal break, column base thermal break. Thermal Break Material (TBM-3) conducts heat 2,800 – 5,900 times less than aluminum, 700-1,450 times less than steel and 10-23 times less than concrete. For any material, conduction is a function of thickness and temperature difference, so the thickness of a thermal break material should be carefully considered.

TBM-3 Thermal Break Material is manufactured in a range of load capacities for various load conditions within the building envelope. It can be used as a thermal break under columns, roof posts, and dunnage connections providing continuous insulation where thermal bridging normally occurs.

It is also ideal for use in window rough openings or as a support buck for metal framed window and door installations, reducing heat loss between the metal frames and steel stud or wood framing openings. TBM-3 thermal break material is also an effective thermal break at curtain wall and storefront transitions.

• Supports up to 2,200 psi

• Thermal resistance of R 2 – R 4.2 per inch

• Mildew, mold, rot and moisture resistant

• LBC Red List Free

The thermal conductivity of a material is a function of its conductance which helps determine the rate at which heat flows through that material.  Heat flow is also dependent on area and temperature.

Conductance is a function of thickness, so to be effective at reducing heat flow through a connection, the thickness of the thermal break is important.

TBM-3 thermal break material is available in thicknesses from 1/2″ to 12″ to accommodate a wide range of connection details.  In any connection design, the goal is to use the appropriate thickness/area which helps meet energy code requirements for the wall or roof assembly.
