Information

The small detached house was renovated to improve its energy efficiency. First, the base and top coats of plaster were removed. This was followed by a new build-up with Fixit 211 cement mortar, Fixit 222 aerogel high-performance insulating plaster (layer thickness 40 mm) and the mineral substrate stabiliser Fixit 493. This was followed by mesh embedding with Fixit 223 special embedding mortar, a primer coat and Fixit 730 abrasion with a grain size of 3–4 mm.

This historic building, dating from 1651 and classified as worthy of preservation, shows the centuries on its exterior façade. For the energy-efficient renovation, Fixit 222 Aerogel high-performance insulating plaster was applied to the façade in a layer thickness of 7–8 cm using a spraying method. Fixit 203 finishing plaster with hydraulic lime was applied as the finishing coat and then painted twice with Fixit 784 OF mineral sol-silicate paint. The exterior wall adjacent to the stable next to the building was insulated with 140 mm thick COMPACT PRO rock wool insulation boards.

Historic building ‘Mühlestock’ renovation Madiswil

The historic Mühlestock building in Madiswil is a listed building, which meant that external insulation was not an option in this case. In order to renovate the building in line with conservation requirements and improve its energy efficiency, Fixit 222 Aerogel high-performance insulating plaster was used. This allowed the interior walls to be visually preserved with their original character and historically curved, slightly sloping walls. The insulating plaster was applied to the quarry stone masonry of the interior walls with a layer thickness of 3–8 cm.

This detached house from the 1920s is the first Minergie-certified building in Switzerland to be renovated for energy efficiency using Fixit 222 Aerogel high-performance insulating plaster. In order to retain the window reveals, the old plaster was completely removed and then replaced with Fixit 222 Aerogel high-performance insulating plaster. Finally, the entire façade was painted twice with Fixit 786 Si silicate-silicone roll-on paint in a dark terracotta shade. Thanks to the low layer thickness of Fixit 222 Aerogel high-performance plaster, the original appearance of the building was retained.
