Thermal Insulation in Fribourg

Are you looking for a thermal insulation company in Fribourg for a house, a block of flats or a co-owned apartment? The city’s buildings are very varied: old town houses, rental blocks, villas on the hillside. Each case calls for a different solution, and the quote depends first of all on what your building allows.

Thermal insulation in Fribourg: the most common jobs

Insulation covers several distinct interventions, which can be carried out together or in stages:

• the roof and attic, often the simplest item to deal with;
• facades, from the outside or from the inside;
• floors and unheated cellars;
• treatment of thermal bridges (balconies, lintels, junctions between walls and slabs);
• window replacement.

In Fribourg, the question is not only “what to insulate” but “how far the building allows it”. A recent villa and a medieval building in the Bourg offer very different room for manoeuvre.

Bourg, Auge and Neuveville: insulating in a protected old town

Fribourg’s old town is medieval and very extensive. It includes the Bourg district, the Auge and the Neuveville, set within the loop of the Sarine. The canton has protected old towns, and you should assume that any intervention visible from the outside is closely examined.

In practical terms, for a building in this area:

• external insulation changes the thickness of the wall, its relationship with the windows, the surrounds and sometimes the eaves: it may be refused or have to take a very discreet form;
• internal insulation preserves the facade, but reduces living space and shifts the moisture issue into old walls that are often thick and not very airtight: the choice of materials and the method of installation matter a great deal;
• the roof and attic often remain the most feasible works, provided the appearance of the roofing is respected;
• windows may be subject to requirements on shape or proportions.

Before hiring a tradesperson, ask the municipality and the competent cantonal department whether your building is protected and which rules apply.

An elevated site and the canton’s winters: where to insulate first

Fribourg grew up on a spur overlooking the Sarine. Buildings are therefore exposed to wind and cold to varying degrees depending on their orientation and position relative to the slope. The canton itself stretches from the plateau to the Prealps and the Gruyère, snowy in winter: winters matter in the reasoning, even if your property is in town.

A few useful pointers:

• a poorly insulated roof or open attic lets a lot of heat escape, and is often the first thing to examine;
• cellars and floors above unheated rooms are best dealt with during a wider renovation;
• thermal bridges show up in winter as cold patches, condensation or mould in corners;
• on an older building, replacing windows without touching the facade can shift the moisture problem: professional advice is essential for the overall balance.

A CECB helps to put this work in order. It avoids starting with a visible item when another weighs more.

Permits, FRIAC and subsidies: the procedures in Fribourg

External insulation changes the appearance of the facade. A permit may therefore be required, depending on the municipality and the building. In the canton of Fribourg, building permit applications are submitted through the cantonal FRIAC platform, and the permit is issued by the prefecture or the municipality depending on the type of work. To find out which route applies to your project, the safest course is to ask the municipality before fixing the start of the work.

On the funding side:

• the Buildings Programme can support some insulation work, depending on the canton;
• the canton has a subsidy programme, run by the cantonal energy department;
• the conditions (eligible work, timetable, documents to provide) must be checked before signing a quote, because an application submitted too late may be refused.

No amount is given here: only the energy department and the programme concerned can confirm what you are entitled to.

Rental block, co-ownership or villa: who decides?

In Fribourg, a significant part of the housing stock is made up of buildings with tenants, with the presence of the university and a student population. This changes how decisions are made.

• Owner of a villa or house: you decide, within the building and protection rules.
• Co-ownership: insulating the facade or roof affects the common parts; the decision normally goes to the owners’ meeting, according to the co-ownership regulations.
• Tenant: insulation is the landlord’s responsibility. You can report cold, damp or draughts to them, but you cannot bring in a company without their consent.
• Small business: if you rent premises, the owner’s consent is also required.

Describing your building to compare insulation quotes in Fribourg

The more precise your description, the more comparable the quotes will be. State:

• the type of building (house, block of flats, co-owned apartment), its approximate period and its district;
• whether it is in the old town or in a protected area;
• the areas concerned: roof, attic, facades, floors, cellars, windows;
• the problems observed (cold, damp, mould, high heating bills);
• whether a CECB exists;
• site access: narrow street, slope, no room for scaffolding, inner courtyard.

A good quote details the type of materials, the planned thickness, preparation of the substrate, finishes, any scaffolding, waste removal, and what is included or excluded. It also states whether the company handles the procedures or whether they remain your responsibility.

The cost varies with the area treated, the choice between exterior and interior, the difficulty of access, the condition of the substrate, the materials, the finishes and the building’s protection constraints. Compare several quotes line by line rather than on the total. To get started, you can request a quote describing your work: your request is passed on to tradespeople and companies in the region, who will contact you to prepare a free, no-obligation quote.
