The best noise control on the market

Easy to install

Easy to install

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 43.4

Outstanding noise control 43.4

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

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.

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.
