Each SG3 barrier weighs just 13 lbs (6 Kg) and uses Velcro straps instead of cable ties to keep in place, making them easy to install. One person can deploy a full SG3 enclosure, complete with a removable roof.

Outstanding noise control
The SG3 Safegate barrier absorbs almost 100% of noise at 500Hz-1kHz. It also achieves world-class noise reduction at a wide range of other frequencies (15dB at 500Hz; 32dB at 2kHz).
Weatherproof

Because SG3 acoustic barriers are certified waterproof to IPX6/9, they can be used in heavy rain without harming performance. They can also withstand both extreme heat and cold, and are guaranteed to last at least 5 years.
The Echo Barrier user manual provides clear guidelines on the correct use of Echo Barrier products along with the terms and conditions of use.

What makes our acoustic barriers so effective?

The best way to understand how our temporary noise control barriers deliver market-leading performance at minimum weight is to take a look inside.

Front facing outer layer
We use super-durable, waterproof PVC, ensuring the best possible noise reduction without sacrificing appearance.
Noise-absorbent composite
Highest grade, acoustic absorbent made from recycled materials prevents noise from reflecting off the barrier (bio-degradable).
Waterproof breathable membrane
Absorbs sound, not water.
Durable reinforced mesh
Keeps our barriers working for years in even the harshest conditions.
