Rock wool: an insulator inspired by volcanoes
The Rockwool, also called stone wool, is an incredible insulating material inspired by nature and more particularly by volcanoes. In fact, rock wool is made using a mixture of basalt (volcanic rock), limestone and / or clay heated to over 1400 ° C and passed through a sieve in order to obtain filaments. The latter are then assembled either in the form of panels or in the form of rolls.
The rock wool thus obtained is a thermal insulator but also a sound insulator. It is resistant to humidity but also to insects.
Glass wool: easy to handle
The glass wool is a material which consists in particular of sand and recycled glass. To obtain glass wool, these components are heated and sprayed using a specific pipe. Then, once cooled, they take on the appearance of a wool called glass wool.
Marketed in the form of panels or rolls, glass wool is both a thermal insulator and a sound insulator, just like rock wool. One of the strengths of this material is that glass wool is very easy to handle and install. Indeed, even beginners do-it-yourselfers can very easily make their cutouts and put it in place in a home as part of a construction or renovation…
But that's not all, and glass wool has other very interesting assets:
- First, it is rot-proof, which means that it does not rot.
- It also has the advantage of not absorbing water and can therefore be used in damp rooms such as the bathroom.
- Finally, glass wool is not particularly flammable: its fire resistance makes it a secure material to favor in homes.
What safety measures should be adopted with these materials?
Wool and rock and glass wool are materials to be used without fear. Indeed, they are not dangerous for the health, nor for the safety of the inhabitants of your household.
The two insulators are very easy to install: they can be cut using a cutter or large scissors. Wearing DIY gloves and safety glasses is obviously recommended in order to limit the risk of cuts!
Rock wool or glass wool: what to choose?
Finally, rock wool and glass wool are very similar insulators. Here are a few things that can help you choose between these two materials:
- Glass wool is resistant to insects and termites.
- Rock wool is resistant to rodents.
- Both materials resist humidity well and are not very flammable.
- Rock wool is slightly more expensive because its manufacturing process is more complex. Its energy performance is also more important.
- Glass wool stands out for its quality / price ratio.
Before choosing, the ideal is to call on a professional in order to make an energy balance and find suitable solutions.
To note: in DIY stores, you can also get valuable advice, especially if you want to undertake the thermal and / or sound insulation work on your home yourself. So don't hesitate!
