Your project in the canton of St. Gallen

The canton of St. Gallen almost entirely surrounds the two Appenzells and stretches from Lake Constance to Lake Zurich. The city of St. Gallen is known for its old town with oriel-windowed houses and for many buildings from its textile era. Rapperswil and Jona, on the shore of Lake Zurich, combine a historic centre with newer residential districts. Wil and Gossau are busy regional centres, while in the Rhine Valley, Altstätten and Buchs lie close to the Austrian border. The Toggenburg, around Wattwil, is a hilly landscape of farms and timber chalets. The canton is German-speaking, but your request can be written in English. For an old house in a town centre, ask your municipality whether the planned work requires approval. Give the municipality and postcode and describe building access, whether the project is in town, by the lake or in the Toggenburg.

  • For an oriel-windowed house in St. Gallen's old town, attach photos of the façade and windows.
  • In the Toggenburg, say whether the house is isolated and how it can be reached in winter.
  • On the shores of Lake Zurich or Lake Constance, describe access to the plot and the space available for materials.

Insulation work in the canton of St. Gallen

The canton of St. Gallen has a very varied building stock. In the city of St. Gallen, buildings with oriel windows and the town houses of the old town are insulated delicately, through the lofts or from the inside. In Gossau and Wil, villa districts and post-war rental buildings benefit from complete external insulation. Around Lake Zurich, in Rapperswil and Jona, houses near the water require particular attention to moisture. In the Rhine Valley, towards Altstätten or Buchs, and in the Toggenburg, around Wattwil, timber farmhouses and village houses face cold, snowy winters. For old façades in St. Gallen, enquire at your municipal office.

  • In a Toggenburg house, insulate the floors above unheated spaces such as cellars or former cowsheds.
  • For an old oriel window, ask for suitable thin insulation, as these projecting volumes lose a lot of heat.

Frequently asked questions

What information should I send for an insulation project in St. Gallen?

State the type of building, its age and which parts you want to insulate, such as the roof, walls or floor. Add photos and, if available, an energy report or plans of the house. This helps the company assess the options and plan a visit.

Why should moisture be assessed before insulation is added?

Existing dampness, air leakage and the proposed layer arrangement affect how an insulated construction behaves. Covering a problem does not establish its cause. Ask for an assessment of the relevant building element and the treatment of joints, ventilation and moisture before work proceeds.

What should I compare in insulation specialist quotes?

Compare the insulated area, material, thickness and treatment of interfaces. Clarify removal of existing finishes, scaffolding and reinstatement. Ask how windows, services or adjoining construction are handled, and which supporting assessment or documentation is included for the proposed system.

How should I prepare for the insulation specialist visit or work?

Gather available plans, energy reports and photographs of damp or damaged areas. Explain which rooms remain occupied and whether external access is restricted. Do not remove suspect old materials yourself; agree any inspection and preparatory work before insulation is installed.
