Bridges connect two points. Thermal bridges also create this connection. Heat finds its way to the outside air via the thermal bridge. This increases heating requirements and heating costs, and compromises comfort. Low surface temperatures in the area of thermal bridges can lead to condensation, creating an ideal breeding ground for mould growth.
This easy-to-use window sill installation mortar, containing lightweight mineral aggregates, prevents this thanks to its excellent thermal insulation properties, ensuring that heat remains within the room.
