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.
