Masonry acoustic isolation strips

An acoustic isolation strip designed to decouple walls from shared footings. Can also be used for steels to isolate them from the support structure.



Manufactured from recycled rubber crumb

  • Vibration isolation break between masonry walls and foundations
  • Suitable for all types of block walls
  • Easy DIY installation
  • Easy to cut
  • Thin but robust
  • Highly efficient
  • Flexible
MIS-5 and MIS-10

6mm and 10mm Masonry acoustic isolation strips: specifically designed to sit beneath blockwork walls and are a very simple and effective way to reduce structure-borne noise. Being rubber crumb, it has the benefit of longevity, minimal creep and is made from recycled material.

These Masonry acoustic isolation strips can also be used for isolating steelwork and heavy steel beams from direct wall connections and help to prevent flanking noise transfer.

  • Offers long term performance without failure under high load
  • Resistant to ageing and deformation
  • Easy to install simply bond to the subfloor beneath the blockwork
  • Capable of withstanding loads up to 0.6N/mm² (60,000kg/m²) with low frequency isolation performance achieved

Versatility: Available in widths up to 1000mm

Size: Supplied in strips to special order. The standard width listed above is 100mm wide but we can do anything up to 1000mm wide. For different widths please contact us directly.

Installation: The base floor must be dry, clean, free of dirt and dust and flat. The strip can either be loose laid or bonded to the base floor.
