Screedcheck XL9 system from Isomass features a 9mm closed cell non cross linked foam layer 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.
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. When installed correctly, the XL9 system will enable compliance with Approved Document E 2003and subsequent amendments in2004, 2010, 2013 & 2015.
Closed cells prevents water absorption which can impair acoustic performance. All installations over 500m2 come
with a free site pre screed inspection.
