This is a question that is often asked about sound insulation when people are concerned about the types of materials used.
The good news is technology has come a long way in recent years towards making materials that are kinder to the environment and less expensive to produce. There is also a growing movement towards using wholly natural materials, though their potential when compared to the equivalent man-made products are questionable when they can end up costing more.

One of the best ways to reduce noise in larger properties is to fit a green roof. It is no coincidence that we are starting to see more and more green roofs when there are some obvious advantages.

From a sound insulation point of a view, a green roof can reduce interior sound levels by as much as 40 decibels, which makes it ideal for buildings where peace and quiet is important such as university buildings.

A green roof also provides excellent thermal insulation which saves on heating costs as well as a home for wildlife. A green roof can be installed on most buildings and it can be combined with other sound insulation materials to create a greener environment.
