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.

The direction towards high-density living has required more noise abatement for a better quality living/environment.

Acoustiflex^® PL5/15 pipe lagging comprises of a Calcium Carbonate loaded noise barrier, bonded with a high density Polyurethane ‘Hydrolysis Resistant’ acoustic foam. This bonded double layer of heavyweight, but flexible acoustic insulation is housed within a heavy duty reinforced aluminium foil casing.

Acoustiflex^® PL5/15 has been rigorously tested by NATA and CSIRO laboratories - complies with the requirements of the Building Code of Australia 2011 (Ref. F5.6)* 40 + Ctr.

The product should be correctly installed (by professional installer) in conjunction with a minimum 10mm plasterboard ceiling.

The flammability rating of Acoustiflex^® PL5/15, according to AS 1530.3, is rated zero in all four indexes of ignitability, spread of flame, heat evolved and smoke developed. It also complies with 
ASTM E 84.

Acoustic Performance PL5/15

To achieve Rw 40+CTR - Lag pipes with Acoustiflex^® PL5/15 together with a 10mm thick plasterboard ceiling and 50mm 6-8kg/m3 insulation.*

To achieve Rw 45 - Lag pipes with Acoustiflex^® PL5/15 together with a 10mm thick plasterboard ceiling.

Calculating the width 

W = ∏ x [OD + (2xT)] +50 mm overlap

W = width of Acoustiflex^® PL5/15 to go around the pipe 

OD = Outside pipe Diameter
T = Acoustiflex^® PL5/15 thickness  (15mm)

∏ = 3.14

Installation Procedure

Easily cut Acoustiflex^® PL with a knife or scissors to avoid wastage.

Wrap Acoustiflex^® PL around the pipe overlapping all joins by 50mm (vertical & horizontal) to avoid potential flanking noise.

Wrap 3 circumferential wraps of high-quality 48-72mm wide reinforced aluminium tape at approx. every 350mm (ie. 3 wraps /1m of pipe length) and tape along seams.

* Ensure a minimum separation of 50mm between the pipe and the plasterboard ceiling.
