Facts About Particleboard and MDF - Engineered Wood Products ...

Acoustic Properties
Sound transmission loss is another property that depends greatly on the building element and its method of
installation. However, as a general figure, Particleboard flooring should achieve a sound transmission loss of
at least 25 db.
The transmission of impact sound is the most likely form of sound transmission with timber floor systems; ie
the noise of footsteps reaching a room below. The simplest solution to this problem though is the use of soft
floor coverings - carpets or rugs. The prevention of impact sound transmission via structural design involves
the use of damping materials between sheet flooring and joists and some mass in the sub-floor space (such as
dry sand) to attenuate direct sound transmission.
Bio-deterioration
As with most other wood products, Particleboard is susceptible to attack from wood destroying fungi and
termites. However moisture contents of over 18% must be maintained before either form of biodeterioration
can occur.
Moist conditions are more likely to occur with flooring than with most other applications for Particleboard.
Information on prevention of moisture build-up is provided in Applications & Installation Sheet 1 - Domestic
Flooring.
Fungus resistant Particleboard Flooring should be used where there are any doubts about preventing
moisture build-up or liquid water contact. Such cases may arise with difficult soil drainage conditions under
the floor or where experience indicates a risk of leaks from shower recesses, plumbing or overflowing
appliances. However it should be realised that Particleboard Flooring, like other wood products, will not
perform satisfactorily if its full service life is under saturated conditions.
Particleboard Flooring is also available with termite and fire resistance.
