The environmental impact of a green roof is undeniable, and adds significantly to the LEED Point system designed by the USGC in all five major areas: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. Green roofing replaces the green space displaced by a building, prevents excess stormwater drainage, reduces the temperature of a building and the urban heat island effect, protects and extends the useful life of a roof, and reduce energy demands. What's more, a green roof incorporating AirDrain means your design includes renewable, recycled, and locally obtained materials. Airfield Systems knows you have a choice in designing a green roof, and hopes you consider the many benefits of AirDrain.
Building green involves the business of manufacturing. Therefore they do not manufacture products or by-products which can negatively impact our world.

Cosella-Dorken take pride in their work and in their products. "DELTA® protects property. Saves energy. Creates Comfort." is one of the guiding principles for their company and, at the same time, for their product range. Out of respect for nature, environmental protection is strictly observed in all areas of the business.
Eco-Roofs’ Standard and AGR™ green roof systems are tray or modular systems with an emphasis on green roof technology. The modular approach when compared to the traditional built-in-place and intensive style of green roof is much lighter, faster and easier to install. The Eco-Roofs system has improved on what most modular systems have done by making the standard module one that arrives on the rooftop with 95% or more already established vegetative cover.
Compare the cost of green roofing with conventional roofing systems! Interested in green roofing but not sure how to determine its long-term costs and benefits, especially compared to traditional roofs? Stop wondering. Green Roofs for Healthy Cities (GRHC) with support from Tremco Roofing and Building Maintenance and the Athena Institute, are proud to bring you the GreenSave Calculator, specifically designed to help professionals concerned with sustainability. The GreenSave Calculator was developed by GRHC and the Athena Institute with funding by Tremco.
The soil in green roof systems acts like a sponge and absorbs excess rain water. Research has shown that extensive green roof systems can reduce runoff by up to 90+% annually (varies with climate, soil and pitch of roof). Green roofs reduce the impact of each new building on the municipal storm drainage system and surrounding watershed. They reduce flooding, erosion and artificial heating of water which helps preserve fisheries and other aquatic life. Green roofs reduce the need for on-site storm water management systems and according to Seattle based Magnusson Klemencic Associates, under certain conditions, can offset the cost of a green roof by 30 to 60%. When combined with an effective rain garden (bioswale), green roofs can make it possible to have zero discharge of rainwater from the site, therefore saving money by not having to connect to the storm sewer system. The LiveRoof® System can help you achieve LEED certification in several categories.
For over a decade, Carolina Stalite Company has been providing the most specified and successful green roof growing media in the United States. Leaders in lightweight aggregate technology for sustainable horticulture, several award-winning green roofs in America utilize PermaTill as the growing media. Stalite Greenroof products meet all ASTM and FLL guidelines for greenroof growing media.
