When it comes to acoustic underlay, there are a few eco-friendly options available. The Eco Ultimate Silencer acoustic subfloor is one of the most popular choices. It is suitable for laminate, bamboo, hardwood planks and engineered wood and is 100% recyclable and environmentally friendly. It also features Crushpruf technology that resists crevices.
Another option is Eco Cork Foam. This product is made with polyethylene as a binder, which is much better in terms of smell and gas release. It also has filaments placed randomly by air to create a capillary effect that dampens the ground, dampens ambient sound and absorbs impact sound. The VersaWalk is another great option for acoustic underlay.
It suppresses noise inside the room and inhibits its transfer to the downstairs rooms. It also has a pre-incorporated sublayer, so it's important to check the warranty before adding another subfloor. Rubber acoustic subfloors should be avoided, as they are one of the products with the highest gas emissions in a home. A better option is AcousticWafer F, which compresses layers of denim fibers to form a dense, acoustically absorbent material for acoustic panels.
It achieves an impact reduction of 18 dB, outperforming other comparable acoustic base layers.
