- System Summary
- SOPRANATURE® ® Intensive Vegetated Systems by SOPREMA® correspond to heavy green roofs with more than 300 mm of SOPRAFLOR substrate. Vegetation types can include a wide variety of perennials, shrubs and trees that require frequent maintenance and heavy structural capacity.
†Systems labeled "Inverted" are designed for a protected membrane roof assembly, also known as an inverted roof assembly. While Semi-intensive and Intensive vegetated roof systems are permitted only on protected membrane roofs (See the Article 1.1.3.2. in the "RGC Standard for Vegetated Roofs"), some system manufacturers offer their systems for conventionally insulated roofs. To request a written Variance to this limitation, follow the requirements in Article 1.1.3.6..
