AGelFa - Development of surface structurable final-coating stucco systems on high-performance heat-insulating aerogel insulation plaster for historic building facades.

High-performance insulating plaster systems represent an important option toward improving the thermal insulation of historic buildings without changing their physical appearance. The high-performance aerogel insulation plaster has recently become available for deployment. In this context, the present will explore final stucco systems suitable for building with structured surfaces.

Abstract

Issues and context

High-performance insulating plaster systems represent an important option for improving the thermal insulation of historic buildings without changing their physical appearance. The high-performance aerogel insulation plaster has recently become available for deployment. In this context, the present project will explore final stucco systems with structured surfaces suitable for building. The project will address both technical requirements (strength, durability, moisture behaviour, ) and architectural considerations (visual effect, texture, feel, colour, aging, need for reinforcement mesh). The project partners will 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).

Targets and methods

Required developmental work shall be conducted with:

Test surfaces in the Röfix company laboratory
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 demonstration facades will be observed and evaluated.

Expected results

Comparison of grain, texture, and colour of the final stucco systems
Use and definition of purpose
Experience and guidelines for craftsmanship
Measurement of results and experience of the mechanical and thermal stress resistance of the final-coating stucco systems
Test results for hydro-thermal behaviour
Assessment of the application potential depending on the system price
Architectural / historic preservation assessments
Creation of reference surfaces
