Application

Thermal and acoustic insulation for flat roofs.

Description

ROCKWOOL HARDROCK Multi-Fix (DD) is manufactured from renewable volcanic stone which produces a non-combustible roofing insulation board. The boards are compatible with a range of flat roof systems, including single-ply, EPDM and liquid membranes, bitumen, and green roofs.

The product offers extremely high acoustic performance – especially in conjunction with ROCKWOOL Acoustic Infills and ROCKWOOL Acoustic Membrane – providing a robust, fire resistant and acoustically-sound solution to flat roof insulation.

Tested to the highest European fire classification, it meets the highest LPCB standards. It has also achieved European Reaction to Fire Classification of A1 non-combustability. In the specification of fire resistant insulation, it is crucial to consider characteristics such as combustibility and toxicity. The product provides an acoustically sound, non-combustible and non-toxic solution to flat roof insulation.

Features and benefits:

  • Achieves Euroclass A2-s1, d0 (non-combustible).
  • LPCB (LPS 1181: Part 1 Ext A) and FM approved.
  • Excellent acoustic reduction, absorption and impact performance – whether from people, machinery or rain on the roof.
  • HARDROCK® Multi-Fix (DD) is dimensionally stable and will provide long term consistent thermal performance over its lifetime.
  • A sustainable solution, made from natural materials, HARDROCK® Multi-Fix (DD) can be recycled and reprocessed, reducing landfill costs, with zero ODP and GWP.
