EzyShield Commercial
Noise Attenuation Walls

EzyShield Commercial is a robust panel machined with a weather-enduring profile and manufactured to AS/NZS 2269-2008. EzyShield Commercial has been pioneered and developed by Boral Plywood over the last 20 years and is part of some of Australia's biggest infrastructure projects such as Melbourne's Eastlink, the Pacific Highway from Brisbane to Surfers Paradise and many train corridors through Australia.

The product is designed to meet the needs of shielding home owners and pedestrians from road or rail noise nuisances. It can be built over 6 metres high and being light, compared to stone or concrete, can be installed in difficult terrain or sensitive sites. As a modular system the EzyShield Commercial fence solution can be easily modified at minimal cost should the requirements for noise abatement change in particular installations.

Sheet Sizes

EzyShield is available in the following sizes with other sizes available on request:

• Thickness: 24mm, 27mm and 33mm
• Width: 1200mm (cut to size 600mm / 400mm)
• Length: 2400mm and 2700mm

Boral Plywood recommends consulting a fencing installer or suitable engineer to determine the correct thickness to use. A suitable soil report should also be obtained before designing the fence.

Enduring Profile

EzyShield is manufactured with a rippled profile designed to control climatic weathering that may occur over time. To increase the stability of the EzyShield Commercial fence, timber battens fixed in the middle of the sheets or bays are recommended.

Sound Transmission Class (STC)

The National Acoustic Laboratories measured the acoustic transmission loss of two thicknesses of EzyShield and obtained the ratings shown below:

• EzyShield 24mm 14kg/m≤ - STC24*
• EzyShield 33mm 18kg/m≤ - STC28*

*National Acoustic Laboratories Reports AFT480 and AFT481 respectively

Jointing

A tongue and groove joining system is used to couple panel edges, giving a strong, warp resistant structure.

Design Freedom

Steel, timber or concrete posts may be used. Panels are usually installed horizontally due to their cross dimensional stability therefore requiring fewer posts. It should be noted that fences over 2000mm in height should only be installed on steel posts (Galvanised UBs) using non-direct fixing method (See Figure 2.0).

Some popular design options combine glass or acrylic clear panels and steel, allowing highways, roads, pedestrian walkways and cycle ways to be safer with more light and less chance of vandalism.

EzyShield Installation

Hampden Fence has been accredited by Boral Australia Pty as installers of EzyShield. Currently we are the only New Zealand Company that has this accreditation. The twenty five and forty year warranties that EzyShield carry are dependant upon correct installation procedures being followed.

Hampden Fence representatives have visited the Boral manufacturing site and have gained an understanding of the importance of these procedures. This knowledge, combined with recent experience installing the product, gives us confidence we can deliver quality Noise Attenuation Walls using EzyShield.
