Isocheck ResiScreed 6, 8 & 10

Under screed systems for all types of concrete floors

The Isocheck ResiScreed systems are designed to reduce impact sound transmission through all types of structural concrete floors.

Isocheck ResiScreed 6, 8 & 10 comprises a 6mm, 8mm or 10mm reconstituted rubber crumb layer bonded to a DPM fibreglass backing that has been designed to be placed within a masonry structural floor directly below the screed. This isolates the screed from the structural sub floor, and provides sufficient impact absorption to place it amongst the top performing systems available.

  • Three Thickness Options: 6mm, 8mm or 10mm reconstituted rubber crumb layer
  • Superior Performance: Amongst the top performing systems available
  • Water Protection: Composition prevents water transmission which can impair acoustic performance
  • Quality Assurance: All installations over 250m² come with a free site pre-screed inspection
  • Guaranteed Compliance: Free indemnified design details guaranteed to pass Part E compliant sound test
  • Eco-Friendly: 80% recycled tyres composition

To be used under screed for all types of structural concrete floors. Suitable for new build, refurbishments, and conversions.

ResiScreed 6 (6mm thickness) is ideal for projects with minimal height restrictions while still achieving excellent acoustic performance.

By ensuring that all the joints are taped, bridging will be eliminated which is the single greatest cause of failure of any system of this type.

Isocheck ResiScreed 6, supplied by Isomass Ltd. Unit 14 Papworth Business Park, Stirling Way, Papworth Everard, Cambridgeshire CB23 3GY and installed in accordance with manufacturer's instructions / recommendations.

The floor surface should be swept free of any loose debris that may damage or bridge the system.

Butt joint and seal all roll edges of Isocheck ResiScreed 6. At perimeters overlap ResiScreed 6 onto a right angle flanking edge strip which should be turned up all vertical surfaces to allow a minimum 50mm to protrude above the intended FFL of the screed.

Perimeter overlaps or butt joints should be sealed with a min 100mm wide Isocheck jointing tape.

Services that penetrate the screed should be isolated by wrapping with ResiScreed 6 which again would be taped.

When trafficking the floor take care not to perform any unnecessary actions that may cause any of the taped joints to be forced apart.
