How to reduce your bill by almost 40% through IT

In the face of ever higher energy bills, many owners and co-owners are looking for durable solutions to reduce their heating budget. Among the energy renovation works, the external thermal insulation (ITE) is distinguished by its efficiency. This technique, which is better controlled, offers heating savings of around 40% on the annual bill. Let us discover together why IT is a concrete response to improve the energy performance of the house, reduce its spending and value its assets.

What is at stake for good thermal insulation from the outside?

The envelope of a building must play a protective role against external variations. However, in old or poorly isolated dwellings up to 25% of energy losses come directly from the walls. This loss results in an increase in the energy consumption, forces to overheat indoors in winter and generates a feeling of discomfort despite the expense incurred.

External thermal insulation This is a strategic solution in the course of energy renewal. By wrapping the building with a continuous insulating coat, the heat transfer responsible for energy waste. This principle leads to a reduction of heat loss and to a tangible gain in Energy efficiency.

How does IT affect energy consumption?

One ITE well achieved acts as a real thermal bulwark between your interior and external climatic conditions. The walls remain warm in winter and cool in summer, which limits the need for heating As in air conditioning. For many households, this means energy bill reduction up to 35 to 40 %, depending on the initial state of the building and the performance of the buildinginsulation implementation.

With this process, not only the heating savings the first cold season, but you also help improve your environmental impact, with less CO emissions₂ related to your accommodation. To better understand how this solution works in detail and discover its concrete benefits, it may be useful to consult this file on the principle and advantages of external thermal insulation.

What materials should be preferred for an effective ITE?

The choice of material depends as much on thermal requirements as on the local climate or budget allocated. The most common insulations for outside thermal insulation These include expanded polystyrene, rock wool, and some bio-sourced materials such as hemp or wood fibre. Each solution has different strengths in terms of thermal conductivity, moisture resistance and durability.

Adapting the type and thickness of the insulation makes it possible to obtain a Optimal energy efficiency the architectural constraints of the existing structure, be it single house or in condominiums.

Reduction of the bill: what to expect with IT?

When performed according to art, thermal insulation from the outside radically changes the thermal behaviour of a dwelling. Beyond the ecological gesture, it is a profitable operation in the medium term. The gain in energy consumption makes it possible to amortise the investment, especially if care is taken to assess the price of an insulation site.

Beyond the ecological gesture, it is therefore a profitable operation in the medium term. The gain on the energy consumption the initial investment, especially if account is taken of the thermal comfort felt in the autumn following the work.

By what mechanism does the bill drop?

The insulated wall greatly limits heat passages between interior and exterior. The need for heating become much lower as the internal temperature remains stable longer after the heating system is extinguished. In other words, less waste, moresavings and one energy consumption adapted to the real needs.

This "mass" effect also benefits the summer comfort: the house warms up much less during episodes of high heat, thus avoiding the use of the air conditioning or to energy-efficient fans.

Does IT optimize the overall renovation of a dwelling?

By opting for a ITE, we put every chance on his side to succeed energy renewal. This choice also increases the "green value" of the property on the market, in particular because the Energy Performance Diagnostic (EPD) often finds itself improved by several classes. Combined with other actions such as changing windows or setting up controlled ventilation, outside thermal insulation ensures more sustainable performance.

Many professionals recommend this comprehensive approach to make the energy transition really efficient and optimize maintenance costs over several decades.

What aids and subsidies accompany IT?

Faced with the initial cost of this work, several public schemes encourage energy renovation. Taking advantage of all existing aid helps to make investment even faster. These supports are also an indispensable lever for renovate an old house in PACA without compromising his finances.

Smaller households are eligible for tax credits, Energy premiums, but also to certain local grants specific to the Alpes-Maritimes or Var. Each dossier is examined individually; it is advisable to realize a Energy audit to identify solutions compatible with your situation.

• MaPrimeRenovation : accessible according to resource conditions, it covers a significant part of the costs incurred.
• Energy saving certificates They provide additional aid financed by energy suppliers.
• Regional or local aid Some communities offer bonuses depending on the location and nature of the work.
• Reduced VAT rate 5.5% for work to improve the energy renewal.

The mobilisation of these Aid gives access to efficient solutions while severely limiting the financial contribution required from families or unions of co-owners.
