Clifford Design have been advising self builders and You Tubers ‘The Restoration Couple’ with their mammoth barn self build. Keen to get the detail right and reduce thermal bridges along the perimeter of the wall/floor junction Clifford Design suggested the use of Marmox Thermoblock. It has proven to be simple to install and will help reduce the risk of a cold strip at the base of the wall. Thermal bridges become more important to address the better the insulation is in a house. Any remaining cold spots attract moisture in the form of condensation if they fall below the dew point leading to a risk of mould growth.
