SilentWool Floor is a roll of 3mm thick Sheep Wool Insulation, that cushions the impact between the finished surface (laminate, solid or semi-solid wooden floors) and the subfloor (concrete or OSB boards). The layer of wool removes the contact between these two hard surfaces by creating an intermediate layer which absorbs this vibration.

SilentWool: Floor rolls are produced in 1m wide rolls and are 25m in length. SilentFloor is supplied with a breathable paper which allows for ease of installation as well as a protection layer.

Please note this product is 100% pure, natural sheeps wool insulation.
Please lay this product paper side up.


Length: 25m.
Width: 1m.
Thickness: 3mm.
Roll size: 25m2.
Natural insulation: 100% pure sheeps wool.

SilentWool Floor
Supplied in 1m width and 25m length rolls. The product should be stored flat on a dry surface. SilentWool Floor can be used under solid timber floors, laminate floors, parquet floors and OSB/MDF boards. It can be installed upon joisted, raft and concrete floors as well as OSB/MDF boards.

Tools required
Scissors, wide moisture-resistant sticky tape, measuring tape and marking pen.

The sub floor must be thoroughly clean and dry. When setting on a concrete floor, ensure surface is even and free from imperfections that may damage the floor being installed.

By design, SilentWool Floor will unroll with the paper layer on top (where fitted). At the walls, take edges of the insulation up the wall by 2cm to avoid sound bridging. Cut around any obstacles using the measuring tape and marking pen for accuracy. Side-by-side sheets should be joined with sticky tape and not overlapped to avoid an uneven finish. Install the timber floor directly onto this paper side of the pure wool acoustic underlay. The paper will not only ensure an even install but will also protect the SilentWool Floor.
Return to the floor edges once complete and fold the underlay behind itself to further insulate from the walls.

Ionic protect
This product is unique in that it is the only product on the market to have Ionic Protect, a new biocide free wool protection system. Ecological, sustainable and durability proven! The procedure treats the wool fibre in a plasma-ionic way aiming to protect it against all the negative influences of the building environment.

Ionic Protect sustains and protects sheepwool insulation, acting as a natural moth repellent and prevents the fibres from being eaten. The performance of Ionic Protect has been checked and confirmed by an independent labaratory (CUAP test).
