The information published in the RCABC Roofing Practices Manual and offered below does NOT represent a complete set of the manufacturer’s data or specifications, nor is this system and its various materials recommended or endorsed by the Guarantor. The preparation of a detailed specification is the responsibility of the Design Authority.

NL720 Sedum Blanket NL512 Retention Fleece NL512 Retention Fleece (Note that this system requires two (2) layers of fleece) NL300 Drainage Mat (Conventional Roof) or Stone Ballast (PMRA) NL120 Root Barrier Conventionally Insulated Roof Assembly by roofing Contractor NL200 Edging & Accessories NL210 Drain Box & Accessories NL220 Penetration Box

^†Guarantor's Notes: 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 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..

^*Conditions and Limitations: Note that system thickness is dependent upon the selection of components, which is determined (in part) by design parameters, including hydrological requirements. Consult with the vegetated roof system manufacturer for options and saturated system weight.

Also note that vegetation coverage under the RoofStar Vegetated Roof Guarantee applies only to extensive systems planted with mats or trays - see Part 3 of Division A for more about coverage.
