Why insulate with stone wool?


When you live in an uninsulated home, you pay high heating or cooling costs to achieve living comfort. These investments have no return whatsoever. Moreover, the inefficient use of energy resources causes long-term damage to the environment. In a well-insulated home, heat is kept where it should be and a sense of coziness and comfort is created. If you once decide to insulate your home, do not compromise – only the right choice of material and professionally done installation will return your investment in the long term. Whatever the weather outside, you will feel cozy in your home. If you make short-term compromises, this will inevitably lead to additional, unjustified costs.

Is it worth it to insulate the exterior walls with stone wool?

Although facade wool is not yet the most popular product, this insulation certainly has many advantages over other materials.

Stone wool breathes

The stone wool insulation system allows moisture particles to pass through effectively
through walls and insulation. The moisture will be absorbed by the fibers of the batting and pass through
the breathable finish placed over it. If there is residual moisture in the walls – a breathable system with insulating wool will allow this moisture to pass out and the walls will be dry.

If an insulation system with XPS is used – this material has a closed cell structure
and this prevents moisture from passing through the system and out. In these cases, moisture and mold sometimes appear on the inside of the wall.

Stone wool has a flammability class A1

One of the biggest advantages of rock wool over EPS and XPS is that it is fire resistant. Laboratory tests show that EPS and XPS can be engulfed in flames in minutes – they melt and release noxious gases. These materials can be used in buildings of lesser height, however, strips of stone wool should be installed around doors and windows to stop the spread of fire.

The isolated facade is protected

Buildings wear out from temperature contractions and expansions, from continuous exposure to moisture, dust and atmospheric influences. The insulated facade is protected from these harmful influences and can last longer without additional wear and tear.

Acoustic benefits

If you live next to a noisy road or have noisy neighbors, facade insulation will limit these noises. Unfortunately, sound travels not only through doors and windows, but also through non-insulated walls. The fibers of cotton wool absorb sound and, in addition to thermal insulation properties, it also provides a high degree of noise insulation.

The price is a reasonable investment

The price of facade wool is higher than those of EPS and XPS, but the prices of the other elements of the system such as: glue, putty, reinforcing mesh and fasteners are the same. The labor cost for installation of the different materials is also the same.

These advantages of facade wool make it a preferred insulation material. Once made, this investment is long-term and you will enjoy the benefits of your well-insulated home for years to come.
