Every year, the topic comes back to the table: the insulation of French houses and buildings is clearly insufficient. Although thermal insulation is a subject of interest for individuals, few people know exactly how to diagnose insulation defects and how to correct them. So, how to properly insulate your house?
Establishing an insulation diagnosis
Before starting thermal insulation work and calling in a professional, conduct an energy diagnosis of your house. Some residential renovation companies tend to overlook this parameter in order to sell you their flagship products, even if they do not actually improve your insulation. Perform an energy performance diagnosis (EPD) as well as an infrared thermal analysis outside your house. This latter technique has significantly developed in recent years and allows you, through different colors, to obtain a thermal map of your house and quickly analyze the defects and thermal needs of your home.

Setting a budget for insulation
Before meeting different professionals, set the budget you wish to allocate to your insulation work. Properly insulating your home comes at a cost, but you should not set a budget based on what the companies that come to estimate will tell you, as this is the best way to spend more than you initially intended. If you need help, there are devices available (we will discuss them a little later in this article). Most insulation work benefits from the tax credit for energy transition (CITE).
Attic insulation, wall insulation, external thermal insulation (ITE): solutions exist!
Based on the results of the thermal map obtained from the infrared analysis and the energy performance diagnosis (EDD), you can already direct your insulation work towards a specific area of your house. Insulation of the lost attic, insulation of the convertible attic, thin layer insulation, wall insulation, external thermal insulation (ITE): there is no shortage of solutions. It is now a matter of choosing the right type of insulation, before of course selecting a high-performance insulating material.

Attic insulation significantly reduces thermal bridges in the roof. 30% of a house’s energy loss occurs through the roof, which highlights the importance of properly insulating your attic, whether it is lost or renovated.
External thermal insulation (ITE) is ideal for achieving high-performance thermal phase shift. Indeed, it is in the walls that thermal inertia is the strongest, allowing for effective insulation for optimal thermal comfort.
Wool, cellulose wadding, eco-friendly insulation: which material to choose?
For insulation under the roof, lost attic insulation, and convertible attic insulation, many insulating materials are available on the market. Glass wool, cotton, natural mineral wool, thin insulation, cellulose wadding, wood wool, straw, cork, hemp, linen: there is no shortage of choices depending on your preferences.
While all have different characteristics, it is worth noting that their use may be recommended for certain regions. And vice versa. For example, it is known that hemp wool is poorly suited for humid environments. If you live in an area with a lot of rain, it is best to avoid it.
Therefore, consider all parameters related to these insulating materials before making your choice.
Benefit from financial support
Properly insulating your house can also mean a financially measured investment. As mentioned earlier, the majority of insulation work is eligible for the tax credit for energy transition (CITE). Two conditions must be met: the professional you use must be certified as a “Recognized Environmental Guarantor” (EGR) and you must install a certain amount of insulation to trigger the QUOTES. In particular, ITE, blown insulation in the lost attic, or sloping insulation are concerned for obtaining the CITE.
In addition, other devices exist for your insulation work, such as the Eco-PTZ or the energy savings certificate (CEE). Ask the Ademe, Anah, or your town hall.
For all your insulation projects, do not hesitate to call on Technitoit, the number one in residential renovation in France.
