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, the 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 FM-DS is a combination of a thermoset acoustic foam with water-repellent Soundmesh G8 on both sides. The Megasorber FM-DS 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.
