Stop-Sound - A thin and sustainable biobased polymer membrane to improve the acoustic insulation of buildings versus traditional oil based membranes.

Acoustic insulation in residential buildings is often very poor. Airborne noise is transmitted from outdoor and between neighbours across buildings. WHO sets maximum acceptable noise levels for the well being of people to prevent anxiety, fatigue and stress leading to chronicle diseases.

Stop-Sound contributes to well-being and quietness, these noise barriers and vibration absorption mats are applied to buildings, industry and transports vehicle. This solution saves space and weight in building structures and is easy to integrate and to retrofit in existing structures insulation membranes. It features high acoustic performances, in low frequencies included. Stop-Sound in made of viscoelastic biopolymers produced from bio based natural compounds which are recylable and bio-degradable polymer (Green chemistry sustainable products). This mats are low in carbon and don't face compound issued from fossil hydrocarbons, they also are free from chemical plasticizers (no phthalates). Stop-Sound is naturally resistant to fire without addition of flame retardants, and resistant to water.
