- System Summary
- Carlisle Semi-Intensive Roof Garden System, also known as a "medium" green roof, is a built-in-place system with a growing media depth ranging from 12.7 cm (5 in) to 20.3 cm (8 in). Semi-Intensive systems are typically chosen for projects requiring greater water retention and/or a more diverse plant palette. Due to the increased media depth and variety of vegetation options, these systems require a heat-welded root barrier to protect the roof membrane. These systems also tend to be heavier and demand more maintenance and watering compared to extensive green roofs (Adapted from the manufacturer's summary).
- Guarantor's Notes
- While Semi-intensive and Intensive vegetated roof systems are limited to only protected membrane roofs (See the Sentence 1.1.3.2.(5) in the "RGC Standard for Vegetated Roofs"), some vegetated roof system manufacturers offer their systems for conventionally insulated roofs. To request a written Variance to the published limitation, follow the requirements in Article 1.1.3.6..
