Issues and context:
For the improvement of the thermal protection of historic buildings without changing their
physical appearance highly insulating plaster systems are an important option. The highperformance
aerogel insulation plaster has been development is now available. This project
will build upon that work. It will now develop final stucco systems suitable for building with
structured surfaces. Both, the technical requirements (strength, durability, moisture
behaviour, ..) as well as the architectural needs and wishes (optical effect, texture, feel,
colour, aging, no reinforcement mesh), will be prioritized in this project. The project partners
will now take the next step in developing a complete system in close collaboration with the
Austrian Federal Office of Monuments and the Urban Design Department of the City of
Vienna (MA 19),
• Planned targets and methods chosen to achieve these goals
Through this research project, it is possible to carry out the still required development work.
With
- Test surfaces in the Röfix company laboratory
and investigations of material and technical processing and with
- Test areas at the Vienna University of Technology and
- 3 "real" test facades on selected (historical) buildings (e.g. in Vienna, Salzburg,
Carinthia, possibly public administration buildings)
the facades will be observed, measured and evaluated, they will be assessed for their
architectural qualities.
• Expected results and knowledge:
- Comparison Results for grain, texture and colour of the final stucco systems
- Use and definition of purpose
- Experiences and guidelines for craftsmanship
- Measurements results and experiences for mechanical and thermal stress resistance
of the entire final-coating stucco systems
- Test results for actual moisture behaviour
- Test results for actual thermal behaviour
- Assessment of the application potential depending on the system price
- Architectural / historic preservation assessments
- Creation of reference surfaces / objects and
- A complete practical system
