Product Description

The Karma Isolation Strip 50mm is a high performance Regupol Impact Noise Reduction product, which prevents sound transfer by isolating the partitioning in party walls or by isolating ceilings and floorboards from the joists they are attached to. It can be used in all forms of construction where there is a point of contact between two items, such as new build, change of use or refurbishment projects.

The Karma Isolating Strip 50mm is typically used to isolate a timber stud or metal framed wall from the structure by sandwiching the acoustic rubber between the floor, wall and/or ceiling and new wall construction – only using the minimum number of mechanical fixings that will safely secure the wall. Regupol Isolation Strips can also be placed on top of the joists to isolate the floor deck – and additionally around the wall perimeter to isolate the floor deck from the wall edges and the skirting boards from the decking.

  • Offers long term performance without collapse or ‘bottoming out’ under high point loads 
  • Standard thickness 6mm although other thicknesses are available upon request
  • Capable of withstanding loads up to and including 0.8N/mm2 with low frequency performance achieved
  • Resistance to ageing and deformation
  • Quick and easy to install – simply bond to the subfloor beneath the blockwork
  • Minimises construction heights
  • High quality and exact material thickness guaranteed
  • Available with various backings including self adhesive backing and Class ‘O’ foil facing

The soundproofing ratings of this product is 23dB impact.

This figure isn’t a measure of the reduction that the product gives, but is the figure that you would get following a soundproofing test after fitting, on the same or a similar full floor set-up to the one used during testing (not just the product in isolation).

Please see the product specification for more details on how these figures were achieved.
