Superior Noise Control

Rw 27 and Rw 30 — NATA-Verified Noise Reduction
Heavy-duty reinforced vinyl and loaded vinyl sound barriers block and absorb noise effectively
Perforated design optimises sound absorption across multiple frequency ranges
High Sound Absorption with Noise Reduction Coefficient (NRC)
Every 10 dB reduction halves the perceived loudness. Rw 30 means the curtain delivers the equivalent of turning a 100 dB source into a 70 dB source at the barrier — a dramatic, measurable difference on any industrial site.

Easy Installation

Quick and easy erection with minimal on-site disruption
Flexible and adaptable design allows for custom configurations and repositioning
Can be mounted using hooks, hook and loop fasteners, or zip ties, depending on the application
Easy disassembly and assembly for seamless access and storage when not in use
Available in standard sizes or custom-made to suit specific project requirements

Project Gallery

"Our project involved the construction of a two storey primary school building in close proximity to working classrooms. In order to mitigate disruption to day to day school activities from construction noise, we engaged Flexshield to supply Sonic Curtain panels to provide a sound barrier between the site and school. The curtains have assisted in developing critical stakeholder/contractor relationships by eliminating classroom distractions. The support and service received from Jeremy throughout the purchase and transportation process was first class."

Are Sonic Acoustic Curtains weatherproof?

Yes, Sonic Acoustic Curtains are designed to withstand outdoor conditions. They are weatherproof, UV-resistant, and often feature fire-resistant properties, making them suitable for use in both indoor and outdoor environments.

Are Sonic Acoustic Curtains customisable?

Yes, Sonic Acoustic Curtains can be customised to meet specific requirements. Customisation options include size, colour, material thickness, and additional features such as vision panels or branding/logo printing.

Are Sonic Acoustic Curtains easy to install?

Yes, Sonic Acoustic Curtains are designed for ease of installation. Depending on the application, they can be mounted using various methods, such as hooks, hook and loop, or zip ties. Additionally, they come with installation instructions to ensure proper setup.

What level of noise reduction can Sonic Acoustic Curtains provide?

Depending on the specific application and environmental factors, Sonic Acoustic Curtains can reduce noise from 15dB to 30dB or more. However, noise reduction may vary based on the installation method, curtain thickness, and surrounding conditions.

Where can Sonic Acoustic Curtains be used?

Sonic Acoustic Curtains are versatile and can be used in various settings, including industrial facilities, construction sites, manufacturing plants, HVAC installations, and commercial spaces where noise control is essential.

How do Sonic Acoustic Curtains work?

Sonic Acoustic Curtains work by blocking and absorbing sound waves. They feature layers of materials that reflect, absorb, and dampen sound, thereby reducing noise levels within enclosed spaces or around designated areas.

What are Sonic Acoustic Curtains?

Sonic Acoustic Curtains are innovative soundproofing solutions designed to reduce noise pollution in industrial and construction environments. They effectively combine sound barrier and noise absorption technologies to minimise noise transmission.
