Acoustiflex^® PL Acoustic Pipe Lagging

A quiet environment is mandated by the Building Code of Australia for residential apartments, hotels, motels, aged care buildings, townhouses and other attached buildings. Acoustiflex^® PL pipe lagging is designed to contain the intrusive noise generated by the turbulent flow of waste-water through piping and fittings.

Acoustiflex^® PL pipe lagging comprises a noise barrier to contain pipe-wall vibrating noise and a high density sound absorber for the wastewater stream noise. This bonded double layer of heavyweight, but flexible acoustical material is housed within a heavy duty reinforced aluminium foil casing. Acoustiflex^® PL is available with a choice of a flat or convoluted sound absorber.

Acoustiflex^® PL has been rigourously tested by NATA and CSIRO laboratories and meets the requirements of the Building Code of Australia for RW+Ctr of 40 when correctly installed.

The flammability rating of Acoustiflex^® PL, according to AS 1530.3, is rated zero in all four indexes of ignitability, spread of flame, heat evolved and smoke developed.

The special construction of Acoustiflex^® PL combines mechanical strength with exceptional flexibility offering significant time savings during installation.

Acoustiflex^® PL is unaffected by water, will not delaminate and will perform continuously over the life of the building without any degradation of acoustic performance.

Installation

The required width of Acoustiflex^® PL to go around the pipe will be given by the following formula:

W = π x (OD + [2xT]) 50 mm overlap

Where π = 3.14

OD = outside pipe diameter

T = Acoustiflex^® PL thickness

Measure the diameter and total length of the pipe to be insulated.

Wrap Acoustiflex^® PL around the pipe and tape with an appropriate reinforced aluminium tape (available on request).

All joints must be tightly butted and sealed in order to ensure a good seal.
