What distinguishes PETRALANA from other similar applications is the very low thermal conductivity (λD ≤0,035 for most PETRALANA insulating materials). Stone wool is completely non-flammable and thus has the highest class of reaction to fire - A1. It also provides excellent material for sound insulation of partitions. The durability of this material, which throughout its life-span does not change its parameters, is of utmost importance. These and many other features allow you to successfully use stone wool at every stage of your investment. If you are planning on building a house or refurbishing an existing facility, check with our application where you can use PETRALANA stone wool products.
