preHAUS walls stand out with their excellent thermal insulation, high heat storage capacity, superior sound insulation, fire safety, and earthquake resistance. They also act like a natural climate control system.
The walls are vapor-permeable, meaning there’s no risk of damage or mold caused by moisture.
preHAUS uses only environmentally friendly and sustainable building materials. Thanks to the vapor-permeable wall structure and the natural properties of wood, the insulation absorbs moisture, temporarily stores it, and releases it again. This creates a comfortable indoor climate with balanced humidity.
preHAUS homes are constructed in modern production facilities using PEFC-certified Scandinavian spruce wood. We rely on ecological building materials, energy-efficient building technology, and long-lasting timber.
Wood, as a building material, offers many natural benefits. At preHAUS, we harness these advantages to promote sustainable, nature-integrated living solutions.
Wall thickness: 28 cm
