Energy efficient construction is a safe bet and creates independency from the fluctuations in energy costs. REHAU system solutions cover all three pillars of energy efficiency: Creating energy efficiently, using energy efficiently, and reducing energy losses. With innovative materials and highly developed system technologies, we offer our customers highly efficient options for positive energy rating and economical solutions for exceeding the EnEV.
*Reducing the energy loss from the window by replacing old wooden/plastic windows from the 80s (Uf = 1.9, U g=3.0) with windows made from GENEO profiles (Uf = 0.86, U g=0.5, window size 123 x 148 cm)
