Sustainable Sound Proofing With Recycled Denim
If you are looking for a sound insulation product for a partition wall? Consider using recycled denim!
Denim insulation is an eco-friendly non-carcinogenic recycled material. It has a multi-dimensional microstructure that isolates and traps sound waves to control noise. With an Sound Transmission Class (STC) of 52 and an Noise Rebound Coefficient (NRC) of 1.15, it can provide superior sound suppression in Retrofits or new builds and is LEED-certified.
STC. It is the ability of a product or material to reduce the transmission of sound between rooms. It measures how much sound a wall, door, window or ventilation system, for instance, will block noise from getting through to the other side. STC is decibels (dB) reduction in noise a material/ partition can provide. Simply put, it measures how much sound a wall, for instance, will block from getting through the other side. Denim is classed at 52 meaning it will stop 52db of energy being transferred beyond the wall.
NRC is measured on a scale that ranges from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up the sound. If a product has an NRC rating above 1 means that it has exceeded the best known sound absorbing insulation at the time of the creation of the scale, which was wool. Which means denim is better at absorbing sound than wool by 0.15.
Not only is recycled denim good at reducing sound transmission, it is also a truly circular building material as it is waste material converted into a building material.
