Developed to combine performance and sustainability, MAC020 Heavy Mass Layer is a new 100% recyclable solution that has emerged as an effective and sustainable substitute for bituminous materials.
This material can be applied in different vehicles - cars, trains, buses or caravans - where good sound insulation and damping properties are essential to ensure passenger comfort.
When used as a core in a panel we have a reduction of 20% of density when compared to other heavy mass layers present in the market
MAC020
Sustainable Heavy Mass Layer
MAC020 Heavy Mass Layer combines high performance with sustainability, offering an effective solution for damping and acoustic insulation which can be used in various means of transport.
Cork’s unique characteristics contributes towards the creation of a solution that guarantees greater passenger comfort and safety.
This solution combines cork, a 100% natural material, with thermoplastics, and is therefore a fully recyclable solution.
The presence of cork makes this material 20% lighter when comparing with bitumen damping materials.
Corkbased materials increase comfort by dampening noise and vibration of a wide bandwith of frequencies
The performance over temperature is superior to bitumen over key service temperature areas.
This solution combines cork, a 100% natural material, with thermoplastics, and is therefore a fully recyclable solution.
In addition to performance, from an environmental perspective, cork solutions also represent a more sustainable choice.
Cork forests are important natural carbon sinks. It is estimated that for each ton of cork produced, the cork oak forest sequesters up to 73 tons of CO₂*.
