Rock Wool Insulation

Rock wool was discovered on the islands of Hawaii, where it occurs naturally as a by-product of volcanic activity at the beginning of the 20th century. Rock wool in its manufactured state has non-directional fibre orientation and the unique characteristics of stone. Rock wool (also known as mineral wool or stone wool) is manufactured from molten rock in a furnace through which a stream of air or steam is blown at temperature of about 1600 °C. The final product creates a mass of fine, intertwined fibres which may contain binder and an oil to reduce dusting. When pressed into rolls and sheets their ability to partition air makes them excellent heat insulators and sound absorbers. The insulation is produced in a variety of densities according to format and function.


Application

  • Masonry cavity walls,
  • Timber frame walls,
  • Roof rafter insulation,
  • Loft and suspended floor insulation,
  • Acoustic separation of flats,
  • Other sound deadening applications
Characteristics
  • Retains dimensional stability over time,
  • R-value unaffected by moisture,
  • Water repellent yet vapour permeable,
  • when thoroughly dried, will maintain the original performance characteristics,
  • Completely resistant to rot, mildew, mould and bacterial growth,
  • Does not induce corrosion,
  • Can withstand temperatures up to 1200°C,
  • Does not contribute to the development and spread of fire or the release of toxic gases,
  • Effectively reduces airflow and sound transmissions,
  • Absorbs acoustic waves and can reduce the intensity and propagation of noise.
  • Production emissions are within UK legally defined limits,
  • Though mineral wool is no longer classified as a skin irritant,
  • Recyclable.
