Thermal insulation, saving energy
For private households, one of the best ways to save energy, and hence money, is to carry out roof or façade refurbishment measures. A façade upgraded according to Germany's latest energy conservation legislation pays for itself over the years. Damp masonry can dry out behind ZF Zierer façade cladding. Cracks are covered and the building is given a new look. Full insulation can save up to 50% on heating costs.
