Rockwool 251 (Industrial slab)
Product DescriptionRockwool 251 is a highly pressure resistant stone wool
slab. ApplicationsRockwool 251 is used for the thermal and acoustic insulation of constructions where high temperatures and mechanical loads (e.g.
vibrations) occur. Advantages• Excellent thermal and acoustic insulation
• Resistant to high temperatures
• Resistant to mechanical loads |  |
