Renovations, heritage and volumes
For your renovation plans in Aarau, federal building register figures are vital. With 467 buildings under heritage protection, it is crucial to contact the municipality early to address permit requirements. The median house volume is 800 m3, which serves as a key indicator for scaling insulation or heating upgrades. Please note that data coverage regarding volume is partial, as only 20 houses were measured according to the SIA 416 standard. We recommend verifying the precise dimensions of your specific property before starting any works to ensure your renovation budget remains accurate and effective for your project.

Why insulate your facade in Aarau
External thermal insulation is one of the most effective measures to improve your building's energy class. By reducing heat loss, you maintain a constant temperature throughout the year.
In Aarau, this helps combat seasonal variations and protects your wall structure from moisture. Beyond energy savings, a well-insulated facade increases your property's value on the local market.

Administrative steps and permits
Also, note that a grant application must usually be filed before work starts, which requires careful planning. For accurate budgeting, use our free RenoIndex simulator to find out the price range in CHF and facilitate your financial processes.
Optimizing renovation costs
Scaffolding is a big share of the cost : it is highly recommended to bundle facade, windows, and roof work to maximize your investments. By carrying out these works simultaneously, you avoid paying multiple times for scaffolding setup.
This comprehensive approach not only reduces expenses but also guarantees homogeneous thermal insulation of the entire building envelope. To estimate potential savings and get a price range in CHF for your work, consult our free RenoIndex online calculator.
Technical site preparation
Good facade insulation requires rigorous preparation of existing surfaces. Before installing insulation boards, walls must be inspected for cracks or signs of moisture. Thorough cleaning and surface repair ensure better adhesion of the insulation system.
It is recommended to hire qualified professionals to perform an accurate thermal diagnosis before starting. If you are looking to anticipate costs, our RenoIndex tool provides a price range in CHF to help you budget with confidence.
