   Home      Dunlop Timbercushion Underlay

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.

Dunlop timber flooring underlays are Australian Made and guaranteed for the life of the flooring. 
Dunlop Timbercushion provides superior acoustic performance within multi-storey applications offering improved privacy and comfort levels for the occupants.  Recommended with most common engineered wood and solid timber floating floors where superior noise reduction and resilience is required.  Dunlop Timbercushion is treated with one of the world's leading antimicrobial agents Ultra-Fresh and it offers protection from mould, mildew, fungi and bacterial growth for a more hygienic environment.

Dunlop Timbercushion conforms to the standard AS ISO 717.2-2004 & BCA 2010 Spec F5.2 set by the Building Code of Australia (BCA) for acoustic performance Ln,w + C1 = 62 dB.  For further information open the links below.
Please Note: Bare Slab Ln,w + C1 result was 68 dB.  Testing was conducted in accordance with standard ISO 140-6, over a 150 mm reinforced concrete sub-floor.
The terms to describe the impact sound insulation of the floor is the "weighted normalised impact sound pressure level" (Ln,w) plus the "spectrum adaptation" (C1).  The lower the Ln,w + C1 for the flooring assembly, the better the performance of the floor in terms of impact sound insulation.
