Mineral-based insulation in existing buildings – the potential of insulating plasters for interior and exterior use

Improving the energy efficiency of historic and heritage-worthy buildings presents particular challenges for planners and contractors. Facades must be preserved, existing structures taken into account, and risks relating to building physics reliably managed. Mineral insulating plasters offer a wide range of options for this purpose.

Thanks to their seamless application, they adapt to uneven substrates, curves and complex component geometries. They combine thermal insulation with the plaster finish, are vapour-permeable, have capillary conductivity and help maintain a balanced moisture balance within the structure. This makes them particularly suitable for older buildings, listed buildings and refurbishment projects where conventional insulation systems reach their limits.

The presentation outlines the properties and applications of mineral insulating plasters for both interior and exterior use.

Practical examples provide an insight into different systems and demonstrate how energy efficiency requirements can be reconciled with the preservation of historic building fabric.
