Insulation underlays
Insulation underlays - an integral part of the installation
Premium insulation underlay to meet the strictest demands for indoor and footfall sound insulation.
We recommend an insulation underlay for all hard subfloors. You consequently increase the resilience of the floor and level out minor irregularities of the subfloor. Insulation underlay absorbs both footfall sound and indoor sound, which is unavoidable when walking on the floor. Not only is this pleasant for you and for your neighbours, your floor benefits from soft and resilient underlay and is thus more durable in case of floating installation, since there is no direct contact with the typically screed surface underneath.
HARO Silent Energy DS insulation underlay offers optimum footfall sound insulation over underfloor heating. The comprehensive HARO range also provides many other alternative insulation underlays that are ideal for installation over underfloor heating. Among these is the natural footfall sound insulation in the HARO ECO LINE, which fulfils the strictest ecological standards. Based on natural materials, such as cork, wood fibre and cardboard, these biological insulation underlays ensure a natural heat and footfall sound insulation.
Here you can find an overview of our insulation underlays
COMFORT LINE insulation underlays
Premium insulation underlays for highest demands on footfall and room sound insulation. The high elasticity reduces strain on joints and spine. Be kind to your ears, joints and spine – with the Silent Pro luxury insulation underlay. It minimises footfall and room sound and gently cushions each step – as if you were walking over moss. That's why this resilience is also called the "forest floor effect".
