Installing underfloor heating in a renovation or new build often means choosing between slow, bulky systems and the risk of cold spots. This DANFOSS thin-bed heating mat solves that by providing an ultra-thin, self-adhesive mesh that lays directly under tile, stone, laminate, or engineered wood floors, delivering 150 W/m² of even warmth across a 3.5 m² area.

Who is it for

This mat is for professional installers and experienced DIYers who need a reliable, quick-to-install heating solution for small to medium rooms such as bathrooms, kitchens, or hallways. It is particularly suited to renovation projects where floor height is limited.
