What is the difference between rock wool and glass wool?

Glass wool and rock wool are the new alternative materials for improving thermal and acoustic insulation on a building site.

We will now proceed to explain the differences between rock wool and glass wool.

Rock wool and glass wool are two of the most ideal materials for insulating rooms. In addition, they are non-combustible materials with very good fire resistance. Despite their similarities, there are other notable differences between glass wool and stone wool.

At KM Steel, we use these materials on our construction sites, in the form of rock wool or glass wool sandwich panels. Their good results precede them. Depending on the type of work and needs, rock wool or glass wool will be more suitable.

In order to differentiate between glass wool and rock wool, it is important to consider the properties, as in other respects they are very similar.

Main differences between glass wool and rock wool

  • Origin

Rock wool, as its name suggests, has its origin in volcanic rocks, treated at high temperatures (1,600 degrees). The result of this combination is a very strong wool fibre. Glass wool, on the other hand, comes from glass yarns, also exposed to high temperatures, to become a highly resistant and insulating fibre.

  • Sound insulation

The thickness of rock wool or rock fibre is greater than that of glass wool, which helps to achieve the objective of acoustic insulation in a building.

  • Thermal insulation

One of the main differences between rock wool and glass wool is the thermal insulation power. Although both materials perform their task exceptionally well, rock wool contains heat better, reducing heat loss, thanks to its thickness and density.

Both materials are ideal if we want to insulate facades or walls inside a house.

Main advantages of glass wool and rock wool

  • Sustainability: Both materials have this property, as they are made from recycled materials.
  • Versatility: another of the great benefits of glass wool and rock wool is that they can be used in a wide range of projects.
  • Resistance: As well as being recycled materials, they do not degrade and can last for more than 50 years.
  • Non-carcinogenic: one of the most outstanding points is that their use does not affect people’s health. Classified as such by an official body such as the
  • International Agency for Research on Cancer (IARC). Agencia Internacional de Investigación del Cáncer (IARC).

In conclusion, all works should have materials as good as rock wool and glass wool and in KM Steel you will be able to enjoy them at the best price. If you want to know our budget, write us through our website (change web) or write us by mail to info@kmsteel.es
