High-Density Roof Rock Wool Board – Fireproof & Acoustic Insulation Core

No.LL-RWBS-01
High-strength rockwool board (HP series) is specially designed and developed for various flexible waterproof roofing systems, which integrates the functions of heat preservation, fire prevention, sound insulation, and noise reduction.
With high compressive strength and point load, it can not only meet the needs of carrying personnel and related equipment weight during the construction and maintenance of the roof system, but also maintain stable thermal insulation, sound insulation, noise reduction, and fire prevention effects. Mainly used in new, expansion, and existing building roofs, planting roofs, and flexible waterproof roof systems. Perfect for single-ply roofing systems (PVC/TPO/EPDM) and standing seam metal roofs.High point load resistance to prevent insulation crushing during maintenance.
