Renovate the attic to keep the house cool

Summer is ideal for energy renovation work, it is an ideal opportunity to protect the house from the summer heat. The choice of insulation with high thermal resistance is essential.

Indeed, when the sun is at its highest, it causes a sharp rise in the temperature of the roof, at the level of the wall of the attic. Depending on the density and diffusivity of the insulation, this temperature rise will reach the roof with less amplitude and after a more or less long period of time.

For the attic, be demanding on the choice of your insulation. It's the perfect time to discover a brand new product from ROCKWOOL: ROCKCOMBLE EVOLUTION. A new 100% rock wool, 100% premium single layer insulation solution which is in line with the Group's product innovation policy and following the launch of ROCKPLUS PREMIUM last fall.

ROCKCOMBLE EVOLUTION offers high performance thermal insulation not only in winter, but also in summer. Rock wool makes it possible to limit the penetration of heat into the habitat as much as possible. Thanks to their high density and thermal conductivity, ROCKCOMBLE EVOLUTION panels increase the thermal inertia of the wall. They have a low diffusivity allowing to delay and attenuate the transfer of the heat flow from the outside to the inside and bring comfort and well-being in summer as in winter. The opportunity for users to save energy.

In addition, with ROCKCOMBLE EVOLUTION, time savings and installation comfort are guaranteed: up to 50% of time saved during the installation of the insulation compared to a two-layer solution!
