Vegetative Roofs are complex systems; they require quality products from the underlying roof structure
through the plant material. Being the most comprehensive vegetative roof system on the market, AVRS®
Tray and Multilayer Systems require the highest quality underlying waterproofing, which is why we primarily
sell through the following partners. This allows for optional full-system warranties with overburden coverage,
from the waterproofing up.





The buildup of greenhouse gases (GHG) which include: Carbon dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O), can cause the earth’s temperature to increase. This occurs when such gases become trapped and buildup within the atmosphere, creating an insulating effect on the earth. These warming effects can be heightened within urban areas, due to dense populations and increased emissions of fossil fuels, most commonly stemming from CO2. Without human influence, Carbon dioxide levels naturally fluctuate with seasonal changes. In the northern hemisphere, during spring and summer month’s plants intake CO2, removing excess amounts of it from the atmosphere produced by human-caused actions. In the fall and winter months plants release this CO2 back into the atmosphere. Green roofs are beneficial in urban areas and help mitigate urban heat island affect because of the plants natural ability to absorb pollutants; such as GHG, and they intake carbon dioxide from the atmosphere, a process known as carbon sequestration.
