Product Description

IsoMat™ is designed to form a resilient layer reducing impact noise transmission in concrete and wooden floors. In a concrete construction, IsoMat™ is laid as a membrane between a structural concrete floor of mass 300Kg/m2 and the finishing screed. For soundproofing an existing concrete floor, IsoMat™ is placed on the existing floor and covered by wooden, engineered wood, or vinyl floor tiles.

The Nankarrow IsoMat™ is consistently popular with end users due to both the high acoustic performance it offers and the unparalleled ease of installation. IsoMat™ is installed as easily as conventional carpet underlay but with the added benefit of superior noise insulation. It does not limit access: it is simply laid under most floor finishes and replaces existing underlay. 18mm Nankarrow IsoMat™ is a remarkably cost-effective and one of the quickest and most effective acoustic solutions on the market. It increases airborne sound insulation and reduces impact noise transmission so much that there is no need for the installation of false floors or false walls. Nankarrow IsoMat™ not only increases minimum ceiling height, but it also reduces labour and materials costs considerably. It is made from an acoustic foam, which does not harden or crumble over time.

Nankarrow IsoMat™ is suitable for anyone looking to minimize both impact and airborne noise. Constructed using a resilient foam core bonded between two attenuating surfaces, it is the perfect insulating material.

Nankarrow IsoMat™ measures 18mm thick and is supplied in width of 1220mm (1.2 meters). You can select the specific length in square feet while ordering the product. It can be loose laid or bonded to the floor or fitted tight up to the perimeters without the need for an isolating strip. IsoMat™ will not transmit vibrations into the walls. Sheets should be laid in a brick pattern, with staggered joints, and butted tight together.

Nankarrow IsoMat™ is a non-fibrous, fire retardant (FR), closed cell, tri-dimensional crosslinked polyethylene foam. It works by creating a vapour barrier with good compression strength. It is certified ‘Class O’ in Fire Propagation and ‘Class 1’ in Surface Spread of Flame as per BS 476 Part 6 & Part 7 respectively. Nankarrow IsoMat™ is an environment friendly insulation material, with a perfect solution for all your insulation needs for soundproofing your floor. IsoMat™ is made up of thousands of tiny cross-linked cells. Therefore even if some cells become punctured, it continues to perform, low thickness loss over long time periods.

You can install this under your existing flooring – tiles, wooden, vinyl, etc.

    5 out of 5 Best way to avoid noise complaints from neighbors

    Reema M.

    It’s an amazing mat with perfect thickness that reduces the impact of noise. We have placed it below our wooden floor. These days I do not receive any complaint from my neighbors even when my kids run or jump on the floor.
