How rock wool is made, why choose PETRALANA rock wool?

PETRALANA insulation materials are used to insulate buildings. They are made of lava, obtained by melting rocks at a temperature of over 1500 degrees. Then they are garnetted, shaped and fixed. The end result is a material that resembles raw sheep's wool.

The benefits of using rock wool insulation materials are divided into three main groups:


Thermal isolation

Mineral rock wool, as a thermal insulation material, ensures maximum insulation of the building in winter. In summer, it prevents the interior from heating up, especially when temperatures reach the highest values. Rock wool, which is produced in Poland, in the PETRALANA factory in Bytom is a product characterized by very good thermal insulation properties. The basic parameter determining the quality of this product is Lambda, i.e. the thermal conductivity coefficient. The lower its value, the better the thermal insulation of the product. Most of the materials that PETRALANA produces are below 0.035 W / Mk, which makes them stand out among similar products.

Fire Isolation

Mineral rock wool products have the highest A1 fire resistance class, which makes them completely non-flammable and provide excellent fire insulation. In the event of a fire hazard, rock stone wool acts as a flame retardant. At the same time, it does not produce harmful smoke or burning drops in direct contact with fire. This makes it very easy to take appropriate fire fighting measures.

Acoustic Isolation

Mineral rock wool is the only sound insulation with such high sound absorption and suppression parameters. "Rock" sound insulation effectively reduces noise, even that of very high intensity. Acoustic insulation of the Polish product is known in virtually all of Europe and puts them at the forefront of rock wool materials available on the market.
