Product Description

IsoMat™ is designed to form a resilient layer reducing impact noise transmission in concrete, tiled and wooden floors. You can install this under your existing flooring – tiles, wooden, vinyl, etc to prevent impact sound leaking to the area below. Examples of impact sound include walking, running, jumping, bouncing a ball, etc.

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 reduces impact noise transmission.

Nankarrow IsoMat™ measures 8mm/18mm thick and is supplied in width of 1270mm (1.27 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, with low thickness loss over long time periods.

  1. Great for dance floor

    Dileep Sanghvi

    Used this as recommended on floor covered with heavy fibercement board and it has stopped the sound of my wife’s dance rehearsal from going down to neighbour.

  2. 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.

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.

Also, consequential and incidental damages are not recoverable under this warranty. Additionally, the products listed below are not covered under this warranty: 1. Accessories & Enhancements 2. Installation Materials 3. Product Samples To minimise colour-fading of acoustic foam products due to exposure to oxygen and ultra violate light, carbon is employed during the colouring process. This does not guarantee the colour fastness of the foam component and you should expect the appearance to change over time. Colour fastness is not covered under the Warranty. This warranty does not cover damage to furniture or equipment caused by contact with or destabilization of the foam components or adhesives and hardware used for installation. Care should be taken when placing the product on finished wood surfaces or other surfaces to ensure there will not be a chemical interaction between the surface finish and the foam component.
