Today we wanted to go a bit more visual for our readers and found what we believe to be a really good infographic design on home insulation.


Thermal insulation is a set of procedures that regulate heat exchange between the inside of a home and the outside environment. More precisely, the concept consists of installing sealing elements on the various walls of the house. If thermal insulation is currently one of the most encouraged renovation projects, it is because it offers economic and ecological benefits, primarily when it is carried out according to the rules of the art.

The main advantages of thermal insulation

Reducing your heating bill is the first benefit guaranteed by thermal insulation. In general, this increase is caused by heat losses, which are only the consequences of an insulation defect. <

That’s why insulating your home well is an additional saving because it reduces your heating needs. But thermal insulation is also a renovation project that leads to the improvement of daily comfort. When carried out by professionals, all accommodation is protected from the cold in winter and the heat in summer.

It should also be noted that isolating habitat is a very ecological approach. Indeed, it is a useful mean in the fight against global warming. Why? Because it limits greenhouse gas emissions into the atmosphere and is thus good for our planet.

Also, if the insulation used is of superior quality, the house benefits from fire protection. Finally, it is important to stress that with good insulation, you can increase the value of your property and also optimize its sustainability.

The keys to successful thermal insulation

A thermal insulation project must be carried out with the most exceptional care. It is the only way to guarantee its success. The first thing to consider is the regulations. It must be said that this type of work is now regulated by law. There are many standards to meet.

Also, necessary thermal expertise is required, regardless of the characteristics of the building to be insulated. It allows to determine the zones of heat loss and air passages and then to know where to start. The work is to be carried out in order of priority.

In general, wall insulation and attic insulation are the essential operations. They reduce the risk of leakage to over 50%. If necessary, the floors should also be insulated. This will be after we can consider insulating the window and doors. Sometimes the ideal solution is to opt for double-glazed insulating joinery.

It should be noted, however, that to succeed in insulation, it is necessary to know how to choose the insulators. For this purpose, there are various elements to take into account, namely the thermal conductivity of the material, its air and moisture tightness, and its thickness. Its thermal resistance must be greater than or equal to 3.7 if it is used in wall insulation, six if it will provide roof insulation and three if it is placed on floors.

Currently, insulators that promise high performance are available on the market to mention only 100% ecological glass wool, cellulose wadding, synthetic insulators such as polystyrene.

A little explanation of the cost of thermal insulation

The cost of the work is an obstacle to its completion. It varies between 40 and 80 euros per m². If the area to be insulated is large, the expenditure will be substantial. The same applies if high-quality insulation is chosen. Currently, many renovation loans are available to French households. They are accessible at a low rate and offer flexible repayment terms. Also, various subsidies are available since thermal insulation is added in projects compatible with energy renovation.
