Home thermal renovation radically transforms the comfort of your home. Insulating walls, attics, and floors represents the very essence of this approach. These three areas account for up to 80% of energy loss.
Your home loses heat through all the untreated thermal bridges. This situation generates excessive consumption and high heating bills. Thermal insulation is therefore the most effective solution to reduce these losses.
Reno, a Parisian renovation company, guides you through every step of your energy transformation. This technical expertise guarantees a successful apartment or house renovation. Energy efficiency becomes accessible to all budgets.
Attic insulation: the top priority in energy renovation
They represent the most significant area of heat loss. This insulation work is therefore the priority intervention in any renovation project. Moreover, the energy efficiency achieved amply justifies this order of priority.
High-performance insulating materials for attics
Rock wool offers excellent thermal and acoustic properties. This material is highly resistant to fire and rodents over time. Indeed, its exceptional durability justifies its frequent use in energy renovations.
Cellulose wadding has a very favorable ecological balance. This insulation comes from the recycling of used newspapers and cardboard.
The recommended thickness for attics should be at least 30 centimeters. This thickness guarantees a resistance greater than 7 m².K/W. Thus, the energy performance meets the requirements of current thermal regulations.
Installation and price of attic insulation
The cost of attic insulation ranges from €15 to €50 per square meter. This amount depends primarily on the type of insulation chosen and accessibility. However, financial assistance for renovations can significantly reduce this initial investment.
MaPrimeRénov’ finances a significant portion of this work, depending on family income. This bonus can cover up to 75% of the total cost of insulation work. Therefore, the zero-interest eco-loan often complements this public aid scheme.
Installation by certified professionals guarantees good results. These craftsmen are fully proficient in essential airtightness techniques. In addition, their expertise ensures compliance with current technical standards.
Wall insulation: techniques and solutions to eliminate heat loss
Walls account for approximately 30% of a home’s heat loss. This proportion justifies the importance placed on their insulation in any renovation project. Indeed, several techniques can effectively address these energy losses.
External insulation (ITE): the optimal solution
This technique eliminates all thermal bridges in the structure. This technique completely envelops the building in a continuous insulating layer. Therefore, energy performance reaches exceptional levels with this method.
ITE fully preserves the living space of the home during the work. Occupants can continue to live normally throughout the duration of the project. In addition, this method also improves the aesthetic appearance of the exterior facade.
The energy savings generated quickly offset the initial investment of this energy renovation. The energy efficiency achieved can reduce heating consumption by a factor of three. Thus, a specialized renovation company in Paris guarantees lasting and efficient results.
Interior insulation (ITI): when to choose it?
It is suitable for buildings subject to architectural constraints. This technique is particularly useful in historically listed or protected areas. Indeed, it preserves the original exterior appearance of the existing building.
ITI also represents a more economical solution than external insulation. The cost of the work remains approximately 30 to 40% lower. However, this technique slightly reduces the living space of each room concerned.
Bonded cladding is the simplest method of interior insulation. This technique attaches insulation panels directly to existing walls. Furthermore, the metal frame allows for easy integration of electrical and plumbing systems.
Materials and thermal performance of walls
Expanded polystyrene offers excellent value for money for wall insulation. This lightweight material makes handling and installation much easier. Furthermore, its moisture resistance makes it ideal for outdoor applications.
Wood fiber has excellent thermal and ecological qualities. This natural insulator effectively regulates the ambient humidity of the home. In addition, its water vapor permeability prevents condensation problems.
The recommended thermal resistance must reach at least 3.7 m².K/W. This performance guarantees insulation that complies with current regulatory requirements. Thus, the energy performance diagnosis (DPE) improves significantly after this renovation work.
Mistakes to avoid for a sustainable project
The success of a project depends on several key factors. However, certain mistakes compromise the energy performance of a home. These errors can be costly for homeowners.
Neglecting the initial energy audit
Many homeowners begin renovations without conducting a preliminary assessment. This approach often leads to unnecessary expenses. An energy audit reveals your home’s weak points and guides your choices toward the most effective renovation projects .
A precise energy performance diagnosis (EPD) identifies priorities. It prevents investments in unsuitable equipment. This step guarantees a consistent and cost-effective energy renovation.
Underestimating the importance of thermal insulation
Insulation is the foundation of any energy renovation project. Some homeowners prioritize the heating system over the building envelope. This mistake increases energy consumption unnecessarily.
A poorly insulated home loses heat quickly. Even a high-performance heat pump won’t compensate for these losses. Insulating walls, roofs, and floors should precede any heating system upgrade.
Choosing equipment unsuitable for the accommodation
Equipment sizing requires precise technical expertise. An oversized boiler consumes more energy than necessary. Conversely, undersized equipment does not provide the desired thermal comfort.
Each installation must correspond to the actual needs of the home. A specialized renovation company calculates these needs precisely and offers solutions adapted to your situation.
Neglecting available financial aid
Numerous financial aid programs for renovations exist in France. However, many homeowners miss out on these opportunities. This neglect significantly increases the final cost of the work.
France Rénov’ centralizes all the information on these programs. Energy renovation work and tax credits can significantly reduce your expenses. A free simulation in just a few minutes reveals your rights.
Carry out the work in several uncoordinated stages
Some owners spread their work over several years without planning. This approach fragments the work and reduces its effectiveness. It also complicates obtaining financial aid.
A comprehensive energy renovation project optimizes performance. The renovation steps must follow one another logically. This coordination ensures maximum reduction in greenhouse gas emissions.
Why insulate your home ? The immediate benefits of home thermal renovation
This project delivers tangible benefits from the very first months. This energy renovation work transforms the daily lives of homeowners. Furthermore, the investment quickly pays off thanks to the energy savings generated.
Drastic reduction in energy bills
Insulation work immediately reduces energy consumption. This improved energy performance can reduce heating bills by 40%.
Owners notice these savings as early as the first winter after the renovations. This energy efficiency helps reduce greenhouse gas emissions. In addition, improving the energy performance certificate (EPD) automatically increases the value of the property.
Improving living comfort and enhancing heritage
Insulation eliminates the sensation of cold walls in winter. This improvement provides immediate well-being to the occupants of the home. In addition, temperature fluctuations become much less noticeable on a daily basis.
Property value increases significantly after energy renovation work. A favorable energy audit attracts more potential buyers to the real estate market. Thus, the price of an apartment renovation in Paris proves to be a particularly wise investment for the future.
