Stone wool

Knauf Insulation stone wool (also known as rock mineral wool) is branded as Heralan®, KnaufRock®, Nobasil®, Rocksilk®, Tervol® and finds its way into thousands of residential and commercial buildings as well as into industrial and OEM applications.

This material is also having an excellent combination of thermal, acoustic and fire insulation properties.

Knauf Insulation stone wool products protect you from heat, noise and fire, providing you with:

• 

  Thermal insulation: energy efficiency in buildings is a key point to choose your insulation material. The heat conductivity is measured by theλ factor where a lower value means a better thermal insulation. Stone wool is reducing the heat loss, which has a positive impact on energy efficiency and thermal insulation. Therefore it is important to apply materials in a way to avoid the condensation of water vapour in the construction, because it deteriorates the quality of insulation.

• 

  Acoustic insulation: sound is the result of the vibration of particles in an elastic environment. To ensure a quiet and relaxing atmosphere, Knauf Insulation stone wool is protecting you from air and impact sounds. The higher the acoustic absorption, the better the acoustic insulation. The acoustic elasticity properties of Knauf Insulation stone wool ensure a top-level acoustic performance.

• 

  Fire protection insulation: Knauf Insulation stone wool is non combustible, which makes it perfect for fire protection. The thermal insulation properties of the insulation material being used in case of fire are also very important as the material will be subject to elevated temperatures. That's why it is important to choose a fire resistant insulation material.
  Our Knauf Insulation stone wool insulation materials are the optimal choice of incombustibility class A1, with a high melting point above 1000°C.

Other properties of stone wool insulation:

• vapour permeable ( " breaths" )
• resistant to aging and decay ( long living )
• resistant to micro organisms and insects
• resistant to chemical substances
• chemically inert and completely recyclable with an ecological production process
