A noise barrier is a solid structure that intercepts and reduces sound. Certain materials like solid metal can reflect sound waves and enhance the sound. Noise absorbing walls, on the other hand, effectively reduce noise. Our standard 70mm panel wall can reduce up to 28 decibels, and our double panel wall will reduce up to 39 decibels of sound.

With each ten decibels increase, the sound is doubled. For example, 60 decibels to 70 decibels sounds twice as loud to the human ear. Our acoustic wall system works effectively to reduce sound. Consult with a BelAire expert to create maximum sound reduction for your property.

BelAire walls are easy to assemble. Two people can easily handle the panels, and can on average put up 20 to 25 metres of 1.8-metro high BelAire Classic wall each day. This is the case even in difficult-to-access areas such as backyards or annexed ground.

There is no for heavy construction, digging equipment or cranos. BelAire provides step-by-step DIY Instructions that any competent DIY handyman should be able to follow. For a professional finish.
