Product image Product image

Timbertech™Original Xtra heavy duty rubber based engineered wood floor underlay is composed of a high quality, heavy mass rubber which significantly reduces in-room noise. It has an integrated backing fleece and built in aluminium vapour barrier to protect against moisture migrating from the sub floor, it is suitable for domestic & contract installations.

It is one of the highest quality room acoustic insulation materials on the market. Timbertech™ Original is thinner and much denser than inferior alternatives so keeps floor height to a minimum.

Timbertech Original Xtra evens out slight surface irregularities of the subfloor. Gives excellent impact sound and airborne noise insulation and the heavy mass ensures that the underlay has 100% stability with zero movement.
