Building with wood: The building shell for your WeberHaus

ÖvoNatur Therm: ecological and energy-efficient

A indoor climate in which you feel completely comfortable - day and night, in every season. For healthier living and energy efficiency. And an indoor air quality that far exceeds legal requirements. The ÖvoNatur Therm building envelope from WeberHaus makes it possible. The renewable and ecological building material wood is the basis of this highly insulating building envelope and thus of every Weber house.

The new standard in prefabricated house construction

When you build with WeberHaus, you can sit back and relax: All our prefabricated timber houses score with excellent energy values and a primary energy requirement that is far better than the current legal requirements for new builds.

In terms of energy, the highly insulating ÖvoNatur Therm external wall is many years ahead of the legal requirements.“

A perfect climate: cosiness throughout the house

Whether you feel comfortable at home is a question of atmosphere. And this is less about the furnishings and more about the living climate. This is precisely where the ÖvoNatur Therm building shell really shows its strengths. Because with its high heat storage capacity and low thermal conductivity, the wood fibre insulation ensures pleasantly warm rooms. At any time of year.

What are the advantages of the WeberHaus building envelope?

  • Wood as a renewable raw material

  • Summer heat protection

  • Thermal insulation in winter

  • Comfortable living climate

  • Healthier indoor air

  • High sound insulation

  • Active moisture regulation

  • Excellent fire protection

  • Outstanding energy balance

Warm rooms in winter

The excellent insulation properties keep the cosy warmth inside the house. The big plus: not only the air, but also the walls are pleasantly warm in a WeberHaus. This small difference between the room temperature and the room surface temperature increases the cosiness of the home enormously.

Pleasantly cool in summer

The big plus: the wall and roof structure with wood fibre insulation ensures that the thermal energy absorbed by them is stored for longer and only transferred to the interior rooms to a small extent. This keeps the rooms in the entire house pleasantly cool - even under the roof.
