Insulating a house: what is the point of using biosourced materials?

Proceed to energy renovation of a home also concerns the insulation of the latter from the outside. This technique aims to reduce thermal bridges which could be created in the structure. In the vast majority of cases, they are responsible for thermal losses who observe each other. For this purpose, the use of biosourced materials is strongly recommended to obtain the best technical performance. How can we ensure that we implement this solution correctly?

The benefit of perfect thermal insulation from the outside

Carry out the insulation of a building consists of wrapping it in a protective layer whose aim is toavoid heat loss in winter. This work also makes it possible to better control expenses relating to heating during this season. From a technical point of view, it is common that thermal insulation is most often carried out from the outside. The main related advantages include energy performance obtained using this method.

The walls are protected against temperature differences, and deteriorate less. Technically, insulate the walls from the outside is much easier than doing it from the inside. You do not need to move your furniture or change the decor for this work.

During the installation of biosourced materials for external thermal insulation, it is possible to occupy the building, and the work in no way affects its habitable surface area.

Further, many savings can be made with the technique of thermal insulation of exterior walls. They are around 80% on heating energy bills. This is why the State enormously encourages owners to insulate their homes in this way. It offers them a variety of devices to help them in this process:

  • MyPrimeRenov';
  • The CEE Coup de Pouce insulation bonus;
  • MaPrimeRénov'Sérénité;
  • The Eco Loan at 0 Rate;
  • The reduced VAT rate.

This aid can be an asset if you wish to resell your home later. Do not hesitate to inquire about the conditions to benefit from it. This way, you can also refresh the facade of your property.

What biosourced insulation is available on the market?

For carry out their insulation work, home owners can now opt for biobased materials. As you can see here, they are already integrated into a variety of projects. Today, the range of biosourced insulation available on the market is very wide. Depending of constraints relating to construction standards or techniques, you can bet on the following products:

Cellulose wadding

It is an insulator obtained by recycling elements such as:

  • The cardboards ;
  • The papers ;
  • Etc

Today, the demand is very strong regarding cellulose wadding for construction of 100% ecological buildings. In addition to being very efficient, this insulation allows water vapor to pass through easily. Use it for insulate your walls from the outside will therefore allow you to optimize the humidity of your home. You will thus avoid excessive humidity or dryness in the ambient air, while reducing your carbon footprint.

The advantages of this biosourced insulation are also appreciated when a fire occurs. In fact, it delays the speed at which the flames could spread. You have plenty of time to evacuate the premises, in order to let the firefighters bring the fire under control. Why adopt this insulating ? It is one of the cheapest options on the market, which is a strong argument in its favor. You can therefore rely on cellulose wadding to insulate your home inexpensively.

The cork

This bio-sourced insulation is of plant origin, and is presented on the market in different ways depending on the uses to which it is put. These are in particular:

  • The signs ;
  • Slabs ;
  • Rolls; Coils.

What are the main properties of cork ? Used as insulation, it helps prevent the appearance of thermal bridges in the House. The material captures heat, and then distributes it to all areas of the home. It is also characterized by:

  • Appreciable rot resistance;
  • Good sealing;
  • An ability to regulate humidity.

All these parameters allow it to be used effectively for insulate walls from the outside, or the interior as needed. Cork can also be placed in any room, including the most humid ones in the house. Its excellent durability makes it a preferred material for this type of work, with the aim ofincrease the comfort of a home. The only downside is the price of this bio-sourced insulation, which is still quite high. However, its performance is worth the investment.

Hemp wool

The great particularity of this insulating is that it is 100% ecological. To cultivate hemp wool, it is not necessary to use:

  • Pesticides;
  • Insecticides.

Furthermore, the quantities of water that must be used are much lower than those needed for cotton crops. This is not the only asset of this bio-sourced insulation. During its development, it is also able to rid the air of a large part of its impurities. The C02 is the most notable of them. The returns obtained by insulating a house with hemp wool are identical to those of mineral wool.

La breathability of walls is thus higher, which has a positive impact on their ability to regulate humidity levels. Heat losses are therefore limited.

Wood fiber insulation for good thermal insulation from the outside

Wood fiber, an exceptional insulator, is distinguished by its ecological properties and its remarkable performance in terms ofthermal and acoustic insulation. This innovative material is made from residues from certain tree species, making it a particularly environmentally friendly choice. Wood fibers often come from softwoods such as pine or fir, making them a natural and renewable product.

Thanks to its fibrous structure, wood fiber offers excellent thermal resistance, thus effectively contributing to maintaining a comfortable temperature inside your home, whether in winter or summer. Furthermore, its sound insulation power makes it a wise choice for reducing external noise and creating a peaceful indoor environment.

A significant advantage of wood fiber lies in its ability to regulate humidity. By absorbing and releasing humidity naturally, it helps maintain a hygrometric balance in the home, thus preventing problems related to condensation and promoting a healthy indoor climate.
