Sustainable urban developments are dependent upon efficient, functional, and smaller multi-family living spaces. While many people love the idea of living in a pedestrian friendly downtown, they balk when they consider being surrounded by the noise created in urban settings. Acoustical insulation is the solution to maintaining the peace and tranquility provided by rural living, while enjoying the accessibility of an urban lifestyle.

Acoustical insulation is the magical stuff that can prevent you from hearing your neighbor’s door slam, the raised voices calling back and forth across the street outside, or the dreaded early morning garbage truck. Sound Transmission Class (STC) is a rating given to products that are designed to mitigate the effect of sound waves. A standard minimum STC rating is 50. Acoustic insulation will have higher ratings, reflecting its ability to block sound barriers and are created for installation between walls and floors.

Here are some examples:
