EnergyLine und EnergyLine plus – The standard programme for energy-saving house construction

You are of the opinion that one should be uncompromising when it comes to house building? Then with our standard EnergyLine programme you are home and dry. This wall system has outstanding technical values and ensures minimum energy costs. With an integrated installation conduit and strong EPS-F plus facade, as a standard feature you have top heat insulation values that are approximate to those of passive houses.
Our extended EnergyLine Plus programme with double panelling offers the same outstanding heat insulation values and makes your VARIO-HAUS home even safer.

In the EnergyLine and EnergyLine Plus series, windows naturally also play a decisive role in the attainment of the planned energy values. The related demands are met by our standard energy-saving, plastic windows with 3-pane insulation glazing.
