Green roof Growing Media can be composed of a combination of inorganic and organic materials and should comply with ASTM or FLL performance standards. Different Growing Media can perform similar functions. As a result, the materials selected should be based on desired performance function, availability and cost.
Penetrations may consist of, but are not limited to, mechanical buildings, penthouses, ducts, pipes, expansion joints and skylights. These Penetrations maybe combustible or fire may have a major impact on their performance. For these reasons, Penetrations need to be protected from fire exposure. Section 714 of the International Building Code provides descriptions of various types of Penetrations and the firestop requirements for those Penetrations
Vegetative Roofing System
Vegetative Roofing Systems are installed over adhered roof systems. There are several types of Vegetative Roofing Systems as noted below, and they can be interchanged without affecting the fire performance of the system
Protected Vegetative Roofing System
A protected Vegetative Roofing System consists of vegetation, Growing Media, Ballast as defined in 2.2, a fabric that is pervious to air and water, insulation, and includes a membrane that provides waterproofing and substrate materials installed over a structural deck capable of supporting the system. Membranes are adhered to the roof deck or supporting insulation.
Vegetative Roofing System Using a Fully Adhered Roof Membrane System
A Vegetative Roofing System using an adhered membrane system consists of vegetation, Growing Media, Ballast as defined in 2.2, and includes a membrane that provides waterproofing and is adhered to attached insulation, or adhered directly to a roof deck
