System/Material Acceptance and Product Details

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.

Vegetated Roof System Manufacturer: Name linked to website here
Accepted for the RoofStar Guarantee Program: October 25, 2024
Accepted for application in: Vegetated Roof Systems
Acceptance Criteria: Refer to the RGC Standard for Vegetated Roofs
System Summary: The LiteN’Less™ III system is lightweight and soilless, with no “loose” growing medium, and utilizes three layers of water retention fleece while still offering solutions for roof retrofits (adapted from the manufacturer's literature).

Manufacturer Online Resource: LiteN'Less III System
System Depth: 45.0 mm (1-13/16") to 62.0 mm (2-7/16")
Growing Media Depth: 20 mm (13/16")
Vegetation Profile: Moss-Sedum
Suitable climate zones: All BC zones except Zone 4, subject to manufacturer's approval
System Components^*: In the usual order, from top to bottom; click on link for Technical Data Sheet (TDS)

NL718 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.
