Green Roofs


A green roof, or living roof, is a roof that is partially or completely covered with vegetation, planted over a waterproof membrane. They serve several purposes for buildings such as absorbing rainwater, reducing stormwater runoff, providing insulation, creating a habitat for wildlife and mitigating the heat island effect. Water is stored by the substrate and taken up by plants where it is returned to the atmosphere by transpiration and evaporation. When installed correctly many green roofs can contribute to LEED points.

I want to thank you for getting things organized as quickly as you did for us and for the follow up calls and site visits that allowed us to get this work done and meet our schedule dates for the road work. As well, your product knowledge and ability to provide the technical support when dealing with the consultants was a major help in getting the system approved and installed correctly.

Not only was there a substantial cost savings realized by the client, there was also a benefit to the road structure as well. The original design road structure number was 3.780 and a calculated traffic (ESALs) of 2,147,000. The revised road structure number using the TX5 is 4.260 and a calculated traffic (ESALs) of 4,593,000.
