Thermoblock® thermal break blocks reduce heat loss due to thermal bridging at foundation to wall transitions and roof to parapet intersections providing continuous insulation at the base of a wall, slab edge or roof parapet intersection where insulation is normally interrupted. They can also be used as a thermal break under door thresholds in Passive House building design.
Thermoblock® supports masonry, wood or steel framed walls and parapets. Unlike other closed cell, foam type thermal break materials, Thermoblock® safely transfers load without deflection or long term creep. The top and bottom material surfaces provide for a mortar bond in masonry applications.
