For your renovation projects in Au, data from the federal building register indicates that at least 9 buildings are subject to heritage protection, requiring early coordination with the municipality to secure necessary permits. Please note that data coverage is partial for certain indicators: information regarding the year of renovation and building volume according to the SIA 416 standard is not available in the current records. We advise you to verify these technical specifications directly with local authorities before proceeding with modernization plans or insulation upgrades to ensure your project aligns with municipal requirements and building standards.

Planning is the most important step before starting. A grant application must usually be filed before work starts. It is also necessary to check local regulations. External insulation changes the building's look and often needs a permit.
Make sure to consult the local building department.
To better anticipate your overall budget, do not hesitate to use the RenoIndex estimator, which will provide you with a realistic price range for your specific facade project while helping you manage the financial side effectively.
Renovation costs can vary considerably depending on your technical choices. A major expense is the construction site setup. Scaffolding is a big share of the cost: bundle facade, windows and roof to avoid paying for setup multiple times.
This strategy allows for significant economies of scale over the long term. To get a clear idea of costs, use the free RenoIndex estimator, which will allow you to compare options and structure your renovation budget effectively for your specific property.
The choice of insulation material depends on your thermal and environmental goals. Options range from expanded polystyrene panels to bio-sourced materials like wood fiber or rock wool.
Each material offers different properties in terms of thermal resistance, durability, and price. It is advisable to compare these materials with a qualified professional to find the best compromise for your house.
To visualize the financial impact of these choices, use the RenoIndex estimator to get a cost estimate adapted to the selected materials.
Once the insulation is installed, regular maintenance of the facade ensures the longevity of your investment. Regularly check the condition of the plaster and sensitive areas like window joints or roof edges to avoid moisture infiltration.
A well-maintained insulation system can last for decades while maintaining high energy performance.
To plan your future maintenance work, you can also refer to RenoIndex's advice and use the estimator to budget for the necessary interventions to maintain the value of your property.
