Thermal Spacer Block Material (TSBM)

What it does

Thermal Spacer Block Material (TSBM) is a thermal break that reduces heat loss at wall and roof purlin connections. It is installed between metal roof or wall panels and the purlins/girts to increase the thermal resistance of walls and roofs in metal buildings.

When to use it

• Between metal roof or wall panels and purlins/girts in metal buildings
• Wherever thermal spacer blocks are required by energy code
• In window sills, or as a buck for metal-framed window and door installations

Key benefits

• R-4.0 to R-5.4 per inch, with compressive strength up to 148 psi
• Conducts heat up to 5,500× less than aluminum, 1,400× less than steel and 22× less than concrete
• LBC Red List Free; mildew, mold and rot resistant
• Produced, manufactured and fabricated in the USA; complies with the Build America, Buy America Act
