Why insulate your attic?
This is the question that is legitimate to ask. Well, know that insulating your attic is essential for several reasons. First, around 30% of heat loss from a house occurs through the roof. By insulating your attic, you reduce this heat loss, making your home more energy efficient and more comfortable. Furthermore, theattic insulation can also help improve the acoustics of your home and prevent humidity problems.
In addition to reducing your energy bill and improving the thermal comfort of your home, attic insulation has other advantages:
You will have understood, there are only advantages to insulating the attic in your house!
The two types of attic insulation
There are two main types of attic insulation: unused attic insulation and converted attic insulation.
-
Insulation of lost attics : It is generally carried out when the attic is not used as a living space. The insulating materials are placed on the attic floor.
-
Insulation of converted attics : In this case, the insulation is applied under the roof. This method is used when the attic is or will be transformed into habitable rooms.
The different insulation materials
The materials used for attic insulation vary depending on several criteria, including their thermal performance, their durability and their impact on the environment. Among the most common are:
-
Glass wool
-
Rock wool
-
Expanded polystyrene
-
Cellulose wadding
-
Polyurethane
-
Ecological materials (sheep wool, hemp, linen, etc.)
Each material has its own characteristics in terms of thermal conductivity, moisture resistance and ease of installation.
Some technical and regulatory considerations to consider
When insulating attics, several technical aspects must be taken into account by professionals:
-
Thermal resistance (R): the higher it is, the better the insulation.
-
Water vapor permeability: important for moisture management.
-
The standards and regulations in force, in particular the thermal regulations (RT 2020).
Is there financial aid for attic insulation?
Yes, several measures are put in place by the government as part of energy renovation work (and this, provided that they are carried out by an RGE craftsman):
All you need to do is find out if you are eligible for this financial aid.
