Window opening thermal break. Thermal Break Material (TBM-3) is a non- combustible thermal break that conducts heat 3,000 times less than aluminum, 1,000 times less than steel and 250 times less than stainless steel. For any material, conduction is a function of thickness and temperature difference, so the thickness of a thermal break material should be carefully considered.
