Complete guide for changing windows in Fribourg

7 °C. With heating requirements estimated at 3233 Kj/year, maintaining thermal performance is imperative for every homeowner.

Changing windows does not only meet a need for indoor comfort to compensate for thermal variations, but it is also part of a sustainable management of your assets.

When your old frames show signs of fatigue such as persistent drafts, condensation, or damaged seals, the time has come to act to reduce your energy bills and preserve the value of your property in the long term.

The choice of materials is decisive, as each option influences insulation, maintenance, and aesthetics.

Wood offers natural warmth but requires periodic maintenance, while PVC represents an economical and robust solution, very resistant to the weather in Fribourg. Aluminum, for its part, allows for very thin profiles and great durability.

Beyond the frame, the type of glazing is crucial to reach the expected performance levels. Double or triple glazing with insulating gas like argon ensures an effective thermal break.

It is advisable to count your windows by size (small, standard, patio doors, bays) to obtain an accurate quote.

Do not forget that opening options, such as tilt-and-turn or sliding mechanisms, also impact daily comfort and the final costs of your installation.

The real estate stock in Fribourg is varied, ranging from historic houses in the city center to more recent constructions in the suburbs.

For buildings built before the 1990s, it is essential to be vigilant regarding the potential presence of polluting materials, particularly in window seals or frames, which may contain asbestos.

A preliminary analysis by a professional is recommended when replacing old joinery to assess the condition of the building and the risk of thermal bridges.

The wall structure, often thicker in old houses, requires an adapted installation to ensure a perfect seal.

Finally, the existing networks in the walls must be checked before any major intervention to avoid damaging electrical circuits or embedded heating pipes.

In protected areas or on visible facades, the shape and color of the frames can be imposed by the town planning department of the municipality. It is therefore essential to contact the municipal administration of Fribourg before any order.

Compliance with the local land use plan (PAL) is essential to avoid any disputes.

Before finalizing your replacement project, present your modification intentions to the local authorities to obtain the necessary authorizations if your work modifies the initial architectural aspect.

This step guarantees respect for the built heritage while allowing for energy upgrades to your property without regulatory infringement.

Tax-wise, the canton of Fribourg allows for the deduction of investments intended for energy efficiency. For buildings over 10 years old, you can choose to deduct either the actual costs or a flat rate of 20% of the rental value.

For those under 10 years old, the flat rate is 10%. If your investment costs exceed your income, know that the surplus can be carried forward over the next two tax periods.

The flow of a project begins with a diagnosis phase and precise measurements taken by the craftsman. Once municipal authorizations are obtained, the windows are ordered.

Manufacturing times depend on the type of materials and the complexity of the chosen glazing, so it is wise to anticipate your needs several months in advance.

The installation itself is ideally carried out outside of periods of extreme cold, although modern techniques allow for rapid installation, limiting the time the openings remain exposed.

Taking into account the 79 frost days per year in Fribourg, it is preferable to favor temperate seasons.

The project ends with the adjustment of the sashes and the verification of air tightness to ensure that the promised thermal performance is effective once the installation is completed.

A common mistake is ignoring the impact of a new seal on indoor ventilation, which can create humidity problems. Before contacting companies, check the condition of your existing ventilation systems.

Count your windows by size for a fairer price and avoid focusing only on the visual aspect at the expense of thermal performance.

Make sure you have an accurate list of all dimensions needed for your joinery. Contact the municipality to check if aesthetic constraints apply to your area. Prepare a complete file including your renovation intentions for aid.

Do not sign any quote before clarifying the deadlines and guarantees offered by the selected craftsman.
