If thermal performance is one of the predominant criteria, the choice of an insulator must also meet many other characteristics, among which are notably the environmental impact or the combustibility of the material. Among the four major families of insulation currently available on the market, mineral insulation is still top of the bill!
Made from sand, recycled glass or volcanic rock, glass wool is a natural material that is generally found in the form of large rolls. Thanks to its flexible structure, glass wool is a mineral insulator which has good thermal and acoustic characteristics, much appreciated in the construction field. It is not for nothing if this material is still the most used! Another positive point: glass wool is non-combustible, that is to say that it does not promote the propagation of flames.
Made from basalt, a volcanic rock, rock wool offers superior acoustic performance than glass wool. Available in rolls, panels or complex, this mineral insulation is also more affordable in terms of cost. Hardly flammable, rock wool is regularly used for insulations which require good flame resistance. It is also the preferred material for constructions subjected to strong mechanical pressure, such as a waterproofed roof or a floor.
Sold in the form of granules or panels, expanded is the ideal insulation for flat roofs. Designed with volcanic rocks, this mineral insulation has many advantages. In addition to its thermal resistance, it is non-combustible and not very sensitive to attack by rodents and other small insects. Beware, however, of the moisture absorbed by the granules which can destroy the effectiveness of the insulation. > Ask for a quote to better insulate your home
