Boppartshof school campus, St. Gallen

Timber construction thought through.

With the new extension building, wing F, the existing Boppartshof school campus in St. Gallen gains a contemporary timber building. The three- to four-storey building creates new rooms for day care, two kindergartens and further school uses, providing a long-term answer to the neighbourhood’s growing need for space.

Embedded in the campus and the terrain

With its organic building form and stepped height development, the new building fits carefully into the existing school campus and the surrounding buildings. Embedding it in the rising terrain creates a direct connection to the outdoor spaces on several levels. Inside, timber and the exposed load-bearing structure define the architectural character of the building.

Insulated with cellulose made in Switzerland

A key element of the project is the consistent use of timber and the resource-efficient materials that come with it. The timber structure is insulated with isofloc cellulose insulation made in Switzerland. The seamless blown-in insulation supports effective thermal protection in winter and a high level of heat protection in summer.

easyfloc protect for structural fire protection

At the same time, easyfloc protect addresses the increased requirements for structural fire protection. The system combines the proven building physics properties of cellulose insulation with high fire protection effectiveness, extending the range of applications for cellulose in demanding multi-storey timber constructions.

One insulation material. Many requirements. One continuous planning process.

For architects, engineers and specialist planners, the advantage lies not only in the insulation material itself, but in the entire system around planning and application. The material-optimised component catalogue already available from isofloc provides coordinated and documented assemblies as the basis for simple, reliable planning. Suitable assemblies can therefore be selected as early as the initial project phase and developed further to suit the specific project.

Advantages for the specialist planner

  • Planning certainty

    Defined, mutually coordinated component assemblies as the basis for further project development.

  • Less complexity

    An insulation solution that is as continuous as possible reduces material changes and interfaces.

  • A holistic view

    Thermal protection, summer heat protection, moisture protection, sound insulation and fire protection can be considered together.

  • Economical constructions

    Material-optimised assemblies enable targeted use of materials and support economical solutions.

  • Support during planning

    Our technical office supports architects, engineers and specialist planners with component assemblies, building physics, fire protection and project-specific questions.

„The Boppartshof school campus is a prime example of how modern timber construction, resource-efficient insulation and high fire protection requirements can be combined into a high-performance, sustainable building solution."
