In fact, a poorly insulated building lets heat escape through its walls and to the outside. To switch to a low-consumption building, you have to think about protecting the "overall envelope" in a sustainable manner. The choice of materials is important. It determines the efficiency of the work undertaken, its durability and comfort. ROCKWOOL stone wool is one of the most effective thermal-acoustic insulation solutions. It also has excellent fire protection properties and retains its performance for over 55 years. Signatory of the FAIRE charter since its launch in April 2019, ROCKWOOL is committed to supporting the Energy Renovation Plan for Buildings which aims to lower energy consumption and eradicate energy poverty in 10 years.
Improve comfort while reducing energy costs
Thanks to its density and thermal conductivity, rock wool increases the thermal inertia of the wall, thus allowing heat to be retained inside. But it also prevents the heat from getting inside during summer periods and ensures that the house stays cool in summer. The thermal comfort of the home is then improved, and expenses related to heating and air conditioning are reduced, and this throughout the year, summer and winter.
ROCKWOOL products also offer excellent acoustic protection: they isolate and dampen vibrations and noise, thus absorbing numerous noise pollution (neighbors, road, rail or air traffic).
Finally, the safety of the structure is a priority. In particular, it is important to anticipate the first of the risks: fire. Rock wool is inherently non-combustible, acts to contain fire and prevent its spread, and does not emit toxic fumes.
Renovate exterior walls
Facade under plaster
20 to 25% of energy goes through the walls. In renovation, whether in a detached house or in an apartment, exterior insulation techniques are not always possible. So how do you do it? ROCKWOOL offers solutions that adapt to all architectural styles.
The technique of laying insulation under plaster is common today when renovating a facade. Today there are techniques for reproducing identically the architectural details of the facades called modenatures. They are then transposed onto the new facade so as to preserve the appearance of the building or to give it a new architectural style.
The performance of rock wool combined with a wide choice of colors and finishes cover all renovation projects. With the Ecorock range, ROCKWOOL offers several solutions dedicated to exterior insulation under plaster.
Insulation of exterior walls from the inside
When you do not want to renovate the walls from the outside (stone wall or particular architectural heritage), ROCKWOOL offers interior insulation solutions. Discover Rockmur, our new versatile thermo-acoustic solution ideal for insulating interior walls and partitions. It provides all the desired comfort both in its installation and in its use. This solution guarantees energy savings, improves comfort and maintains the aesthetics of the existing facade.
Insulate the roof
The roof represents up to 30% of a building's heat loss.
ROCKWOOL offers insulation solutions adapted to all types of work around the roof: in converted attics, lost attics or in insulation of the roof from the outside (sarking).
Transform the attic into a quality living space
You want to convert the lost attic into a pleasant space to live in while providing interior comfort: Rockcomble Evolution is the solution that meets all your expectations. 100% rock wool and 100% premium, this solution offers you a saving of time and comfort of installation (up to 50% of time saved during the installation of the insulation compared to a two-layer solution).
Rockcomble Evolution ensures excellent indoor comfort not only in winter, but also in summer, allowing to delay and attenuate the transfer of heat flow from the outside to the inside and vice versa and thus bring comfort and well-being .
Insulate lost attics for better comfort
Lost attics, although uninhabited, require efficient insulation that provides thermal comfort in summer / winter in the lower floors, while reducing energy consumption.
Insulating lost roof spaces by blowing is a quick and easy method, suitable for renovation. This blowing technique makes it possible to isolate lost attics in areas that are difficult to access by eliminating thermal bridges. jet rock 2 is the blown rock wool solution that guarantees real and lasting performance with its lambda 44, the best thermal performance on the market in blown mineral wool. Really stable in the wind without deflector (up to a wind speed of 126 km / h), this product is insensitive to water and humidity thanks to its non-hydrophilic character and very durable over time (S1 classification) .
It is also possible to insulate the lost attic using rock wool rollers.
Insulate the attic from the outside
In order to give an aesthetic appearance to the house, it is possible to keep the visible interior elements of the roof frame by choosing to insulate from the outside (sarking).
Rockciel, the special sarking insulation, limits heat loss in winter and prevents overheating of underlying rooms in summer while reducing exterior noise. It offers a gain in surface area in the home, durability over time and excellent thermal performance!
Whatever your project, there is a ROCKWOOL solution for all your renovations!
