• New Build
The econocheck underscreed XL5 system is 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 absorbsion to place it amongst the top performing systems available.
The econocheck underscreed XL5 system from Isomass features a 5mm closed cell cross linked foam layer.
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 econocheck underscreed XL5 system will enable compliance with Approved Document E 2003 and subsequent amendments in 2004, 2010 and 2013.
Closed cells prevents water absorbsion which can impair acoustic performance.
Rolls are light and easy to handle.
All installations over 500m2 come with a free site pre screed inspection.

The acoustic floor shall be:
Econocheck underscreed XL5 system, manufactured by Isomass Ltd. Unit 11, Avenue Business Park, Elsworth, Cambridgeshire, CB23 4EY 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.
Econocheck XL5 can be rolled up the wall or lapped and taped to a perimeter flanking strip. Either option should allow a minimum 50mm to protrude above the intended FFL of the screed (see right).
Adjoining roll edges should be butt-jointed jointed and sealed with a minimum 100mm wide jointing tape.
Services that penetrate the screed should be isolated by wrapping with Underscreed which again would be taped.
When trafficing the floor take care not to perform any unecessary actions that may cause any of the taped joints to be forced apart.
Full installation instructions for econocheck XL5 are available upon request. These must be used in conjunction with this booklet when laying the econocheck XL5 system.
