Rockwool 133 (Lamella mat)
Product DescriptionRockwool 133 Lamella mat is formed from strips of stone wool with vertical fibres bonded onto fibreglass reinforced aluminium foil. ApplicationsLamella Mat is suitable for the external thermal and acoustic insulation of ventilation ducts and maintains thickness even on tight bends or corners. Advantages• Excellent thermal and acoustic insulation
• Retains insulation thickness, even on tight angles
• Easy to handle and install
• Superior fire performance enables use of product in escape routes and technical shafts
• Minimal wastage through reuse of cut pieces |  |
