VSS® is Vegetated Sound Structures

The VSS® wall system, patent pending, is a free standing, soil filled, sound barrier wall. It is foliage covered on all sides with sedum tiles, grasses and flowers. VSS® walls significantly reduce noise but, unlike conventional walls, are far more environmentally friendly and sustainable. These walls provide colorful, graffiti free plantings, while reducing vehicle pollutants and producing oxygen from exhaust emissions. They also provide habitat and food for birds and vital insects such as bees. VSS® was developed by a local pre-cast concrete manufacturer. The University of British Columbia tested and found numerous environmental, cost and time advantages over conventional sound barriers. The University's studies, testing, research, and documentation of VSS® are funded by British Columbia's Ministry of Transportation. These reports are available for review.
