Acoustic Underlay | Recycled Rubber Flooring Membrane – AM Eco-Lay

High-Performance Acoustic Underlay: The Recycled Rubber Advantage

AM Eco-Lay is a premium, high-density Acoustic Underlay engineered specifically to solve complex impact noise challenges on concrete subfloors. Unlike standard underlayments that rely on synthetic foams, this product is manufactured using a sophisticated Recycled Rubber process that repurposes 8.5 end-of-life tyres per roll. This not only provides world-class sound insulation but also actively contributes to the global circular economy by diverting significant waste from landfills. Choosing this membrane ensures your project meets modern environmental standards without compromising on acoustic integrity.

Why Choose Recycled Rubber for Soundproofing?

Using a Recycled Rubber membrane like AM Eco-Lay offers significant structural advantages over foam or cork alternatives. Rubber is naturally dense and resilient, meaning it does not “bottom out” or lose its shape under the consistent weight of heavy furniture or high-volume foot traffic. This dimensional stability ensures that the Acoustic Underlay maintains its decibel-reduction properties and vibration-dampening capabilities for the entire lifespan of the building. Furthermore, the material is naturally resistant to decay, providing a permanent layer of protection within the floor buildup.

Professional Installation Guide

To achieve the best possible results with your Recycled Rubber underlay, a meticulous approach to installation is essential. Following these professional steps ensures a seamless chemical bond and maximum noise reduction between floor levels, preventing common issues like acoustic bridging.

Substrate Preparation

Before laying the Acoustic Underlay, the concrete subfloor must be meticulously prepared to ensure long-term stability.

• Cleaning: All surfaces must be completely dry and free from dust, grease, oils, and general construction debris.

• Critical Note: Clean the substrate until all pollutants are removed, but never use soaps or detergents, as these can leave a microscopic film that prevents the adhesive from properly bonding to the rubber.

• Moisture Check: Always ensure there is no rising damp or residual moisture present in the concrete slab. Trapped water or vapour beneath a Recycled Rubber membrane can lead to adhesive failure and compromise the floor’s structural health.

Adhesive Bonding Process

For a permanent and professional finish that complies with Irish building regulations, we recommend using DISPERTEC AR-7329 adhesive.

1. Apply the adhesive to the dry substrate using a professional spatula or a specific notched roller.

2. Use a generous amount of adhesive to ensure the complete impregnation of the AM Eco-Lay’s textured backing.

3. Carefully roll the membrane into the wet adhesive, using a weighted floor roller to ensure all air pockets are expelled for a perfectly flat, level surface.

Sustainability and BREEAM Certification

In the modern Irish construction landscape, using Recycled Rubber is a major benefit for developers and architects. AM Eco-Lay is an ideal specification for projects aiming for high environmental ratings and low carbon footprints. It provides essential credits for LEED and BREEAM Certification in Ireland, offering a documented, sustainable alternative to virgin plastic or chemical foam materials. Its low-VOC profile also ensures better indoor air quality for the end occupants.

Versatile Flooring Applications

Our Recycled Rubber underlay is compatible with a wide variety of premium floor finishes:

• Engineered Hardwood: Enhances the “solid” acoustic feel of the wood and prevents hollow echoes.

• LVT and Vinyl: Provides the necessary density to protect the delicate click-joints of modern flooring.

• Ceramic and Natural Stone: Effectively decouples the tile from the concrete, preventing stress cracks and significantly reducing impact clatter.
