Exterior insulation, a profitable and sustainable investment

Exterior insulation, a profitable and sustainable investment

On the occasion of the National Energy Poverty Day which took place on November 24, 2022, the National Observatory of Energy Poverty (ONPE) specified that the French fleet includes 5 million thermal sieves and that 12 million people suffer from the cold in winter. Today’s construction standards take these energy issues into account, but what about older homes?

When we talk about energy strainers that lose a lot of heat, we automatically think of the attic and the roof. Rightly because poorly insulated, these areas of the house no longer fulfill their sealing mission, thus creating a loss of heat and overconsumption that could be avoided. However, you should know that about 25% of the energy also “leaks” through the walls according to Ademe !

To improve comfort, and ultimately earn money, owners of old homes are undertaking energy renovation work aimed at reducing these losses so that residents feel more comfortable while reducing the amount of bills.

Very often the first item of expenditure before proceeding to other interior fittings is the change of the heating device. Nevertheless, even if the heating produces more or consumes less, the problem remains essentially the same. To treat the origin, it is necessary to carry out insulation work. And among the most efficient and durable methods, there is wall insulation.

External insulation, in practice

Several methods make it possible to improve the insulation of a dwelling thanks to work carried out on the external facade. To choose the right exterior insulation technique, a previous article written by our editorial staff could give you food for thought in order to select the most appropriate method for your accommodation. Whichever technique is used, the benefits are the same:

  • no interior intervention, which does not lead to a reduction in living space (sometimes a source of questions for people who inquire about this method);
  • the entire exterior surface will benefit from the insulating coat which will reduce heat loss as well as the facing which will cover the facade again;
  • the affixed walls also have the effect of preventing the infiltration of heat in summer;
  • the materials used have a lifespan of at least 20 years;
  • the main advantage is to be able to treat all thermal bridges, such as intermediate floors for multi-storey houses, and not just a few sections of walls.

However, this is a costly operation that must be prepared in advance to collect the budget and seek financial aid when possible. To get started, do not hesitate to consult the price per meter2 exterior insulation to get a more precise idea.

In addition, several government aids have been created to help households finance these sometimes very expensive interventions. A boost that can greatly facilitate decision-making. Nevertheless, these aids are subject to fluctuations, which can slow down individuals.

A better understanding of energy issues and sustainable benefits is essential. Associated with an energy-efficient heating system, these are great savings in perspective, both in energy and financial terms.
