The building envelope of your Hanse Haus: make your own personal contribution to the energy transition
There are many ways to build a house. At Hanse Haus, the decision in favour of prefabricated timber houses was made a long time ago, when the small carpentry business Hanse Fertighaus Bau was founded in the Hanseatic city of Lübeck in 1929. Since then, we have continuously developed our construction technology, utilised our experience and continually improved the wall structure in timber panel construction. Build your energy-efficient, sustainable home with us.
Hanse Haus wall construction: A KfW 40 Plus building envelope as standard
1 12.5 mm plasterboard, 2 Vapour control layer, sd = 10, 3 12 mm OSB board,
4 Mineral wool 035, 120 mm, with timber studs (spruce),
5 12 mm OSB board, 6 EPS 035, 150 mm, 7 5 mm silicone resin render
Well-designed EPS wall construction
Our wall combines carefully selected materials with a well-thought-out construction to create a comfortable, energy-efficient home. A direct comparison highlights what makes it so special.
- Wall thickness: 31,2 cm
- Thermal insulation (U-value): 0,13 - very good
- Moisture protection: No condensation
- Heat protection (time delay): 11.5 hours
- Heat protection (insulation): 33-fold
What do the figures mean?
¹ Wall thickness – The thinner the wall is whilst maintaining the same external surface area, the more living space remains inside the house.
² Thermal insulation (U-value) – The U-value describes the heat loss through the wall. A low value means that less heat is lost to the outside.
³ Moisture protection – A good wall construction prevents moisture from accumulating inside the wall. This reduces the risk of condensation and mould.
⁴ Heat protection: Time delay – This value indicates how long it takes for heat from outside to reach the inside of the wall. A longer delay ensures that the heat reaches the living spaces later.
⁵ Heat protection: Damping – Damping describes the extent to which temperature fluctuations are attenuated. The higher the damping, the more consistent the room temperature remains.

The wall construction using wood fibre insulation also offers a number of benefits. A direct comparison highlights the differences in wall thickness, living space and heat protection.
- Wall thickness: 33,0 cm
- Thermal insulation (U-value): 0,14 - very good
- Moisture protection: No condensation
- Heat protection (time delay): 10.5 hours
- Heat protection (insulation): 17-fold

Save energy with all-round thermal insulation
We hear and read everywhere that we should use more alternative energy sources and rely on energy-saving, efficient heating technology. That's the way in which we think.
At Hanse Haus, we start even a step earlier and ensure that you get by with as little energy as possible in your prefabricated house. This not only saves running costs, but also protects resources and the environment.
The thicker the thermal insulation of a house, the better the heat is kept inside. This means that less energy is used for reheating.
In order to minimise heat loss through the building envelope, we rely on all-round thermal insulation that covers all exterior walls, the roof, windows and doors as well as the cellar or floor slab if necessary. The interior walls are also insulated as standard.
Timber panel construction
Our external wall construction for the Hanse Haus prefabricated house
Our ThermoEfficiency wall combines a high-strength construction method with outstanding thermal insulation. The timber frame is hot-glued with high-quality OSB panels under pressure. This creates the panels of the so-called timber panel construction with timber frame construction.
Your advantage: you can attach shelves or cupboards weighing over 250 kg anywhere, on any wall, in any room using normal screws. No drilling or dowelling required.
The clear room height (finished height) in ground floors, upper floors and attics is approx. 2.50 metres, measured from the upper edge of the finished floor to the lower edge of the finished ceiling. Greater room heights, e.g. 2.70 metres, are possible ex works on request.
Advantages of wall construction
Advantages of the Hanse Haus wall construction
- Our walls are suitable for the construction of KfW Efficiency Houses 40 Plus as standard.
- The U-value in the compartment area is only 0.116 W/m²K (total wall only 0.131 W/m²K).
- We use high-quality solid structural timber, planed and kiln-dried for natural wood protection.
- The reinforcement plaster applied in the factory protects against the effects of the weather - even during assembly.
- The seamless external render, which is only applied on site after the house has been assembled, ensures a high-quality external appearance of the house.
- We are happy to offer you alternative façade designs such as clinker brickwork or timber cladding on request.

The roof structure at Hanse Haus
Solid timber construction and optimum thermal insulation
No other factor in a house has such a decisive influence on low energy consumption as the building envelope.
In addition to the excellent insulating properties of the walls, the roof structure of Hanse Haus also ensures perfect thermal insulation.
It not only keeps the heat inside the house in winter, but also protects against heat in summer. Even the standard thermal insulation of our roof structure fulfils the requirements for a KfW Efficiency House 40 eligible for subsidies.
High-quality construction
Solid timber construction for the roof structure
All roof trusses from Hanse Haus are built by carpenters using solid timber construction. In our production, we use state-of-the-art equipment and qualified carpenters who ensure maximum accuracy of fit and quality.
Our roof trusses are made from solid kiln-dried softwood in planed solid structural timber quality and, depending on the structural requirements, in parts from glulam elements. Visible rectangular supports and beams on the outside (e.g. for canopies or carports) are made of high-quality glulam. On the outside, all visible components are given a protective coat of paint.
A tour through our factory in Oberleichtersbach in Lower Franconia will give you an insight into our production process.
Advantages of the roof structure
Advantages of the Hanse Haus roof structure
- You can rely on the carpentry construction of your roof truss made of quality-tested, sustainably produced solid timber and glulam.
- Your roof is designed as standard for a snow load of up to 1.5 kN/m² – depending on regional requirements.
- You receive a 30-year manufacturer's guarantee on the functionality of our concrete roof tiles.
