DIY Installation Guide for JCW Acoustic Easy Fit Mineral Wool Slab in stud walls

  • General precautions: because this product can cause irritation to the skin, suitable protective wear like gloves and eye goggles should always be used when handling and working with it.
  • Cutting the slab: This mineral wool can be easily cut to any size/shape using a sharp long bladed knife. The knife should be re-sharpened often to maintain performance.
  • Fitting the slab: Always avoid cutting the insulation to a tight fit because this will affect acoustic performance. A loose fit will always give better sound control. Fit the slab between the studs using as many layers as the cavity will allow to further enhance acoustic performance (where cavity space is limited, you could consider fitting as an alternative our JCW High Performance Acoustic Quilt, a premium acoustic partition roll giving around four times the sound absorption of standard mineral wool at a thickness of just 52mm).
  • Fixing the slab: JCW Acoustic Easy Fit Mineral Wool Slab is installed in a similar way to standard glass fibre insulation rolls. It is designed to be suspended and fiction fitted between the studs in metal or timber partitioning systems, suspended between the joists of a timber floor or laid over ceilings. Where necessary, JCW Spray Contact Adhesive will help the insulation stay in place until the wall covering is added.
  • Multiple layers of slab can be used, for increased acoustic and thermal performance, where space allows.
  • Fitting resilient bars: When including JCW Resilient Bars, install them at 600mm centres across all the studwork from the bottom to the top before covering with plasterboard to finish
