External thermal insulation, or ITE, is an insulation technique that allows owners to limit the entry of cold air into their interiors. This technique has many advantages to be seen closely for those who need to carry out insulation work in their home.
An external thermal insulation system is a layer installed on the exterior walls. The technique consists of insulating the external sheath of a building to improve its thermal capacities. Thermal insulation systems maintain the temperature of the walls according to the external climate, thus generating an active thermal mass that improves the thermal inertia of the building. Not only does thermal insulation reduce heat dispersion, it also optimizes the wall’s performance throughout the seasons.
In summer, increasing external insulation significantly reduces heat flow, reducing air conditioning usage. In winter, walls that are insulated from the outside cold create a thermal exchange with the heated space inside the buildings. The objective of installing insulation is to reduce the energy bill. It is therefore necessary to ensure that you invest in an efficient system.
White EPS (polystyrene) and rock wool or wood fiber with a waterproofing film finish covered with the final facing or under-coating complex, mesh reinforcement, and water-repellent decorative plaster constitute the element’s thermal insulation from the outside.
The advantages of external thermal insulation
ITE has many advantages:
- Having efficient thermal insulation available in any season
Rooms will stay cooler in summer and warmer in winter than outside. Thus, buildings with efficient thermal insulation provide comfort to occupants throughout the year. - Considerable savings in energy consumed
Having thermal insulation limits heat transfer between the interior and exterior of each room. This helps to significantly reduce the energy consumption of the home. - Avoid the harmful effects of thermal insulation systems installed on roofs
In the long term, thermal insulation placed on roofs has negative effects on the good performance of housing (cracks, mold due to rain, etc.). The implementation of the ITE reduces these constraints. - Respect the environment
External thermal insulation is a non-toxic and completely environmentally friendly solution.
If you want to make renovations to your home, it is therefore recommended to rely on the external thermal insulation system. It is important to note that this technique requires facade renovation. However, the occupants of the house are not forced to leave the accommodation while the renovation work is carried out.
It is strongly recommended to call on a renovation company to receive your insulation system as quickly as possible. A team of professionals in the building field has the know-how, skills and experience to carry out the project within the allotted time and by quality and safety standards.
How is an ITE installed?
The installation of the thermal insulation system outdoors can be done using 3 distinct methods:
- Mechanical fixing: more suitable for renovations. Insulators are attached vertically or horizontally to existing structures at building level.
- Anchored: this is a method of wedging insulation onto existing raw supports, which will then be immobilized using expansion dowels.
- Bonding to uncoated supports.
The work can be done by the owner himself. However, it is best to use the services of an insulation professional to ensure the conformity of the results. It is essential to choose your service provider carefully to avoid coming across an expert who offers no guarantee after the completion of the project.
