The outer wall of the Open Valley Widnau consists of a conventional timber frame construction, which is covered with hempcrete from CANCRET Materials was filled with hempcrete. The timber frame elements are around 32 cm thick (12 cm/20 cm/12 cm) and were prefabricated in a horizontal position by timber constructor Schöb AG. Any timber constructor can use this technology in their own factory or in a field factory.

A particular advantage of this project is the use of a mobile mixing plant that can be flexibly installed in nearby halls. This considerably shortens transportation routes, which not only cuts costs but also significantly reduces CO2 emissions.

The prefabricated wall elements are then assembled as a whole on site using a crane, which speeds up the construction process, saves costs and at the same time increases the efficiency and sustainability of the building project.

A wood fiberboard is planned for the exterior insulation of the infilled timber frame elements.

The apartment partitions in Open Valley Widnau consist of non-load-bearing wooden stud walls, which are clad with 22 mm clay boards and then plastered. The specific wall construction is individually adapted to the sound and fire protection requirements.

This construction method not only offers outstanding technical properties in terms of sound insulation and fire protection, but is also characterized by ecological advantages. As a renewable raw material, wood stores CO₂ and therefore actively contributes to reducing the CO₂ footprint. At the same time, clay building boards have a regulating effect on the indoor climate by absorbing excess moisture and releasing it again as required, which contributes to a pleasant and healthy living atmosphere.

The combination of wood and clay supports a sustainable construction method that not only conserves resources, but also significantly improves the quality of living thanks to natural and pollutant-free materials. These environmentally friendly building materials promote energy efficiency and create a healthy, low-pollutant living environment.

The interior walls of Open Valley Widnau are made of 12 cm hemp bricks and are plastered on both sides with high-quality lime plaster. The hemp bricks used, also a product of Schönthaler AG, are 12 cm thick. These walls do not have a load-bearing function, but serve exclusively to shape the floor plan.

The use of lime putty as a plastering material offers numerous advantages for the indoor climate. Thanks to its natural mold-inhibiting and moisture-regulating properties, it makes a significant contribution to a healthy and pleasant living atmosphere. Swamp lime is also antibacterial and breathable, making it ideal for combining with hemp bricks, which themselves have similar diffusion-open and moisture-regulating properties.

This combination of materials creates a sustainably designed wall structure that not only meets architectural requirements, but also improves the quality of life for residents by creating an optimal indoor climate. These properties are particularly valuable in ecological building projects, as they naturally contribute to improved air quality and the creation of healthy living spaces.
