Rock Wool Insulation

Rock wool type insulation have excellent fire resistant properties. they have a melting point about 1170 Centigrade. This fire resistant ability gives it a huge advantage over insulation products like foam, fibreglass and cellulose that would burn at much lower temperatures. Rock wool products are often used for fire blocking applications, insulating around chimneys and fireplaces and situations where the insulation needs to be left exposed.

Rock wool insulation also has excellent water and moisture resistant properties. It will not absorb water and does not rot, promote mildew, fungi, or bacteria, or sustain vermin.

Rock wool insulation is dimensionally stable. Rock wool insulation products maintain their shape really well. This is extremely important in situations where a snug fit is all that keeps the insulation in place.

Application

  • Masonry cavity walls,
  • Timber frame walls,
  • Roof rafter insulation,
  • Loft and suspended floor insulation,
  • Acoustic separation of flats,
  • Other sound deadening applications
Characteristics

  • Does not induce corrosion,
  • Can withstand temperatures up to 1200C,
  • Does not contribute to the development and spread of fire or the release of toxic gases,

  • Absorbs acoustic waves and can reduce the intensity and propagation of noise.
  • Production emissions are within UK legally defined limits,
