Sheep Wool Insulation's SilentWool Floor Underlay is a dense, pure wool acoustic felt designed to go under timber, engineered wood and laminate floors from the subfloor. It has a density of 100kg per cubic metre allowing it to provide a robust layer of supreme cushioning on which to lay the hard flooring and protect it from the substrate underneath. It lays onto a flat surface such as screed, concrete, or plywood. It also provides acoustic insulation, reducing the sound of footfall by around 50% (a reduction of approximately 21decibels).
The wool floor underlay is lined with paper for two reasons. It is designed to be laid paper side up, so that when flooring is fitted on on top of it, it doesn’t snag the wool. The second clever reason is that if there are any spills on the floor that sort of leak through the gap, the paper protects the wool underneath. The paper is a natural breathable material that is applied with an environmentally friendly glue.
The wool is treated with Ionic Protect® to ensure it is 100% moth proof.
