Today, every load-bearing wall carries one thing in particular, responsibility.

Energy is precious and expensive. Therefore, it is important to use it sparingly and to select the ideal heat insulation. VARIO-HAUS provides just this with construction components with optimum insulation, windows with 3-pane, insulation glazing and windproof building. You can choose from a range that includes our top class, standard EnergyLine wall system, individual passive house walls that match your individual requirements, or VitaTherm ecological walls without PVC or polystyrene.

EnergyLine (Standard)

U-value: 0.11 W/m² °K
Thickness: 41.1 cm.
Also with double layer cladding

PassivehouseLine

U-value: 0.084 W/m² °K
Thickness: min. 49.1 cm, individually calculated

VitaTherm

U-value: 0.14 W/m² °K
Thickness: 36.75 cm
No PVC or styrofoam

This is what makes our house programmes stand out

Heat insulation
Heat insulation is provided by mineral wool, wood fibre sheets or full heat insulation facades. The mineral wool is obtained from the natural materials diabase and dolomite, which are treated using a special process. The advantages include thickness stability, heat and noise insulation. Standard VARIO-HAUS homes possess 30cm-insulation in the roof and ceiling areas, which rises to 40cm in passive houses.

Energy-saving windows
The bulk of the energy lost in a house literally goes out of the window. Therefore, as a standard feature the windows in a VARIO-HAUS home are offered with 3-pane, insulation glazing for optimum heat insulation. The U-value of this type of window is roughly one-sixth lower than that of standard window glass.
 
Shadowing as a standard feature
In all habitable rooms shading by electrically operated aluminum shutters.

Wood and natural gypsum plasterboard panels for an ideal room climate
The use of largely natural materials creates a healthy and balanced room climate. Both untreated, natural wood and gypsum plasterboard help to compensate for and regulate humidity fluctuations.
 
The 18mm-thick natural gypsum panels also allow the problem-free mounting of kitchen cupboards, televisions, etc. directly on the wall.
 

Energy certification included
All VARIO-HAUS homes are highly energy-efficient. Calculated in terms of the OIB directive, the energy characteristic (the specific heating requirement) is stated in kWh/m²a. This is supplemented by hot water and heating system energy consumption, as well as the total final energy demand and the mean U-values of the construction elements and the house.
