Low building height is a clear advantage in multi storey buildings where the size of the horizontal division really matters. – Like in the 54 storey tall Turning Torso in Malmo, Sweden, where DEVI supplied the heating cables for the bathrooms in the otherwise water heated building.
Also in renovation projects, the low build-up height of e.g. Devimat™ systems creates an advantage.
You can mount the 3 to 4 mm. high self-adhesive heat mats directly on top of the existing floor covering thus escape the additional cost and waste of resources on digging up the floor.
