Renovations, heritage and volumes
For your renovation plans in Therwil, the official RegBL figures provide essential guidance. With 715 buildings under heritage protection, it is vital to contact the municipality early to discuss permit requirements. Regarding building volume, the median is 782.5 m3. However, please note that this figure is based on only 16 properties measured according to the SIA 416 standard, while 1894 properties use other standards or are categorized as unknown. Consequently, data coverage for volume is partial. Furthermore, no specific data regarding the renovation year is recorded, which should be considered during your project assessment.

Planning and assessment
To ensure the success of your project, start with a detailed analysis of your existing setup. Count your windows by size, distinguishing between small formats, standard dimensions, French doors, and bay windows.
This method allows you to get a much fairer quote from companies. Consider the orientation of each facade to choose suitable glazing (double or triple glazing) that will optimize solar gain in winter while avoiding overheating in summer.
Structured planning prevents unpleasant financial surprises and guarantees visual harmony for your entire building after the work is completed.
Aesthetic and regulatory considerations
When it comes to window renovation, the choice of frame should not only be technical. In protected areas or if your house has a visible facade, strict rules may apply.
The shape, material, and colour of the frames are sometimes imposed to preserve the architectural character of the neighborhood. It is advisable to find out about any potential constraints before placing an order.
Well-chosen windows enhance your real estate value while respecting the visual identity of your environment. Do not forget that aesthetics play a major role in the overall perception of your renovation quality.
Financing strategy and grants
Financial aid, particularly within the framework of cantonal or federal programs, often targets a comprehensive renovation of the building envelope to ensure optimal energy efficiency.
To reduce costs, prefer an integrated approach by coupling window replacement with wall or roof insulation.
Use our free RenoIndex estimator to obtain a reliable price range, which will help you budget your investment and better anticipate the return on investment through future energy savings.
Impact on energy performance
Investing in high-performance windows is a sustainable decision that directly impacts your energy consumption. High-quality glazing significantly reduces heat loss during winter and improves interior thermal comfort.
By limiting thermal bridges, you also improve the climate of your home and reduce the risk of condensation. Beyond heating savings, new windows improve sound insulation, which is particularly appreciated in residential areas.
To estimate the cost of these improvements, do not hesitate to consult the RenoIndex simulator, which gives you a personalized price range for your specific project.

Frequently asked questions
Should I replace all my windows at once?
It is often recommended to replace all windows simultaneously for energy and aesthetic consistency. This also limits recurring construction costs. If your budget is limited, you can proceed in stages, starting with the most exposed facades.
How can I get a reliable quote?
For an accurate quote, list your needs by window type and contact several local companies. Use the free RenoIndex estimator beforehand to get a realistic price range and compare the offers you receive in an informed manner.
What is the average lifespan of windows?
On average, well-maintained quality windows have a lifespan of 25 to 30 years. After this period, seals and thermal insulation may degrade, making replacement necessary to maintain the energy efficiency of your home.
Can I change my windows myself?
Replacing windows requires great precision to ensure air and water tightness. It is strongly recommended to hire qualified professionals to avoid long-term moisture or thermal bridge issues.
