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.  

In addition to being red list free, the XPS material used in this product is manufactured with a blowing agent that has an ODP (ozone depleting potential) of zero and a GWP (global warming potential) of 0.29.  It is HCFC and CFC free and contains zero HBCD (halogenated fire retardants).
