Why carry out a façade renovation?
Several reasons may motivate a façade renovation:
- Improve aesthetics: a façade renovation gives your home a fresh new look.
- Protect the façade: the façade is exposed to the elements, and renovation allows it to be protected.
- Improve thermal insulation: combined with external insulation, it reduces heat losses.
- Increase property value: a well-executed renovation increases the value of your property.
- Address moisture problems: it can solve moisture or crack problems.
Why carry out a thermal study before the work?
Here are the problems you may encounter if you do not request a prior thermal study.
Poorly managed thermal bridges
- Energy losses and cold zones may appear if the insulation is not properly installed.
Appearance of mould
- Cold surfaces can cause condensation, leading to mould and health risks.
Medium to long-term structural problems
- Moisture can weaken the structure of the walls.
Poor choice of materials and poor installation
- A specialised study helps to choose the right materials and ventilation systems.
How to assess the condition of a building's façade and exterior walls?
Evaluating the façade requires methodical observation. Here are the points to check:
General visual inspection
- Overall appearance: look for signs of problems such as stains or cracks.
- Uniformity of colour: variations may indicate moisture problems.
- Presence of vegetation: moss and lichens can damage the façade.
Detailed inspection of the various elements
- Coating: look for cracks and peeling.
- Masonry: check the condition of the bricks or stones.
- Windows and doors: check the joints to prevent infiltrations.
The different techniques of external thermal insulation (ETI)
- Insulation under coating: the insulation is glued or fixed to the façade.
- Insulation with ventilated cladding: the insulation is placed between the façade and a cladding creating ventilation.
- Insulation with sandwich panels: pre-assembled panels are fixed directly to the façade.
Materials for carrying out façade renovation work
- Coatings: varieties of finishes and colours available.
- Paints: to protect and decorate the façade.
- Claddings: modern and durable in wood, metal, PVC or composite.
- Natural stone: noble material, but more expensive.
The necessary steps to renovate an exterior façade
- Site preparation: installation of scaffolding.
- Cleaning the façade: various methods to remove old dirt.
- Repairing cracks: filling and treating damaged areas.
- Laying thermal insulation: installation of the insulation.
- Laying the finish coating: application of the necessary finishes.
- Finishing and cleaning: installation of finishing elements and cleaning of the site.
