When acoustic treatments are required in external, exposed environments, it is a huge challenge to have a soundproofing system that can survive the full weather.
Traditionally, a perforated metal sheet with glasswool or rockwool infill has been used. In order to prevent these infill materials from getting wet and losing their acoustic performance, a thin plastic film has to be used to wrap the infill materials. However, this reflective plastic film also prevents the sound from being absorbed by the infill materials, resulting in low absorption capacity.
Megasorber water repellent Soundmesh® G8 is specifically designed to meet these challenges. It is non-combustible, water repellent, UV resistant and yet has excellent sound absorption properties thanks to the patent technology.
When a water repellent Soundmesh® G8 is combined with hydrophobic polyester fibre, Megasorber P range product is an excellent candidate for outdoor applications. It has superior sound absorption capacity with NRC (Noise Reduction Co-efficient) up to 1.0.
For outdoor applications where high-temperature resistance is needed, Megasorber WaveBreaker is a combination of a thermoset acoustic foam with water-repellent Soundmesh G8 on both sides. The Wavebreaker is extremely lightweight, and the thermoset foam has a temperature resistance of up to 250°C.
From noisy transformer stations with tonal humming affecting nearby residents to air conditioning compressor units impacting neighbours, and the deafening sound of rain and hail on a metal roof, Megasorber has sound solutions to make life quieter.
A few examples from previously completed projects
With a water-repellent, non-combustible and UV-resistant Soundmesh G8 facing, Megasorber’s FM and P range of acoustic absorption panels perfectly suit the harsh environments of outdoor applications.
Transformer noise reduction and rooftop pant room are just a couple of examples of many outdoor applications.View our FM range of absorption products
Demonstration of enclosure noise reduction
Two identical metal boxes are constructed. The red box has no acoustic treatment. The green box has all the interior surfaces lined with Megaorber FM25, plus a door seal. It is a comparison test for demonstration only.
