Isocheck ResiScreed Under Screed Improvement System

Isocheck ResiScreed 6, 8 & 10

Under screed impact improvement systems

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 provide sufficient impact absorption to place it amongst the top performing systems available.

Isocheck ResiScreed comes with the backing of a free indemnified design details (that incorporate Isomass products) guaranteed to pass a Part E compliant sound test.

To be used on concrete beam and block, hollow core, in-situ and all other types of concrete structural subfloors, for conversions or new build. This isolates the screed from the structural sub floor. 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, 8 or 10 under screed impact improvement system, 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, 8 or 10. At perimeters overlap ResiScreed 6, 8 or 10 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, 8 or 10 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.
