Timber floor underlays

Underlay is required any time you install an engineered timber floor or a laminate floor.  These floor types are installed using a 'floating' method as they are not actually attached to the sub-floor, instead the floor boards are attached together.  The underlay gets laid down over the sub-floor and the laminate or engineered floor is installed on top of the underlay.  The floor boards are attached together either by gluing the tongue and groove, or by locking the boards together, if it is a 'Uniclic' or 'LOC' up system which does not require a glue.  

The function of the underlay is to absorb some of the minor imperfections in the sub-floor and to slightly soften the feel when you walk on the floor.  The underlay also helps to reduce reflected foot noise when walking on the floor since the flooring is not attached to the sub-floor.   

When choosing an underlay for your flooring project, you must use a product that is approved by the manufacturer of the particular flooring.

Also it is important to check with Strata management, if you live in a unit or apartment, what type of acoustic underlay will be required.

Moisture control and noise levels are two of the major and recurring issues surrounding floating timber floors, impacting on their performance across many residential and commercial environments.

Dunlop Acoustic Underlay for timber floors has gone through extensive testing by the CSIRO to determine the acoustic performance and compliance with the standard set by the BCA.  Dunlop's timber flooring underlay's all exceed the standard.
