Fire resilient stone wool insulation slabs optimised for sound proofing.


ROCKWOOL® Sound Slab is used to create quiet, peaceful and comfortable spaces in both residential and commercial environments. Being made from stone, ROCKWOOL insulation absorbs sound waves and reduces vibration due to its density, a non-directional fibre orientation and an open porous structure; trapping and preventing sound waves from traveling through it. ROCKWOOL insulation is also non-combustible, able to withstand temperatures of over 1,000°C.

Features and benefits:

  • Outstanding noise reduction - Quiet Mark™ approved.
  • Euroclass A1 non-combustible.
  • Thermal conductivity of 0.038 W/m·K.
  • Patented FLEXI Edge® for the perfect friction fit.
  • Quick and easy to install, without gaps and minimal waste.
  • CE and Key marked to BS EN 13162:2012+A1:2015.


ROCKWOOL stone wool is highly resilient, durable and dimensionally stable, maintaining its thickness and shape over time. Moreover due to its fibre structure and overall flexibility, stone wool can easily fit into available spaces, helping in avoiding unplanned air gaps, cracks or other installation errors in the final construction, ensuring stable performance over time.

Water repellence:

ROCKWOOL Insulation products work with the fabric of the building, preventing water from penetrating, but allowing moisture vapour to pass through. Vapour resistivity of 5.9 MNs/gm.
