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.
