Isocheck weight-enhanced Barrier Mat systems are primarily used for their airborne, low-frequency damping properties in floors and walls through timber floors and in metal roofs.

Isocheck weight-enhanced Barrier Mat 5 (2 - 3mm) and Barrier Mat 10 (4 - 5mm) are constructed of high-density barium sulphate loaded thermoplastic polymer, plasticized with phthalate esters and containing mineral fillers. They are black in colour, bitumen free, ecologically neutral and recyclable.

Barrier Mats are ideal for upgrades when looking to improve airborne sound reduction with minimal increase in height and depth.

In timber floors, Isocheck Barrier Mats can be laid directly over existing floorboards or draped between joists in floors or sandwiched between two sheets of plasterboard or draped within a studwork wall. In roofs, Isocheck Barrier Mats can be laid directly over a profiled metal deck in a flat roof or built up metal standing seam roofing.


To used over timber floors, within walls and on metal roofs for conversions, refurbishments or new build.

The acoustic floor shall be:

Isocheck Barrier Mat, supplied by Isomass Ltd. Units 10 & 11, Avenue Business Park, Elsworth, Cambridgeshire, CB23 4EY and installed in accordance with manufacturer’s instructions / recommendations.

Installation - floors and walls

Two to three layers glued onto timber floors will dramatically reduce airborne noise penetrating the floor from below or airborne noise you are creating being transmitted from above.

Barrier Mats can be fixed using pins, hangers or banding. Alternatively, it can be bonded using an approved polyurethane-based contact adhesive or a solvent-based acrylic pressure-sensitive adhesive.

Finished timber floors should be isolated from the skirting using Isocheck Acoustic Flanking Band.

Installation - roofs

Lay Barrier Mat directly over the steel deck, across the line of the profiles (as shown).

Overlap Barrier Mat by 50mm min. at joints.

Fit a polythene VCL between the Barrier mat and the insulation. A mechanically fastened single ply membrane should then be laid in accordance with manufacturer’s instructions / recommendations.

Full installation instructions for Isocheck Barrier Mat 5 and Isocheck Barrier Mat 10 are available upon request. Installation instructions must be used in conjunction with this information and/our information contained in the data sheet when laying the Isocheck Barrier Mat floor system.
