A Noise Reduction Coefficient (NRC) is a rating for how much sound a material absorbs.
The higher the rating, the better the sound absorption. So a material with an NRC of 1 absorbs 100% of sound. In the insulation world, NRC is an important factor because along with regulating temperature, insulation should also keep your living space quiet.
Havelock Wool’s NRC of 90 and 95% beats most other insulation mediums. To be fair, there are some products with a slightly higher NRC but those tend to be designed specifically for sound absorption. As such, they fall short on other important metrics like R-Value…. not to mention moisture management, air filtration, and sustainability.
But how can you appreciate insulation with a high NRC before you put it in your walls? Fortunately, Havelock Wool has a great community of ambassadors who share their experiences with us. Check out the latest example below from @lariotsofficial and listen carefully to both what you hear and don’t hear!
