LiteN’Less™ III

The Next Generation of Lightweight and Soilless Solutions

OVERVIEW

The LiteN’Less™ III is lightweight and soilless, with no “loose” growing medium, and the ideal solution that avoids excessive loading. All components delivered in the form of rolls that allow for a clean, fast and simple installation.

KEY FEATURES

Increase BioDiversity

BioBerm™ with custom plants is an innovative method for integrating the best of extensive and intensive green roof features – creating topographic variation and biodiversity. It provides an enhanced aesthetic over areas that are highly visible and that can support extra weight. Achieves a seamless integration of “plant-in-place” vegetation through pre-grown sedum blankets that are rolled over various depths of growing media. The sedum blankets help reduce water evaporation, soil erosion and weed growth.

Unique Design & Logo Creation

Sloped, rounded, pyramid shaped – LiteN’Less™ systems easily adapt and conform to various roof designs.

Increased Stormwater Retention

Option available for supremely effective stormwater management solutions without exerting excessive loading. The innovation is in efficient water retention layers which hold 60% more rainfall compared to typical growing medium of the same thickness while remaining 20% lighter in weight.

CONVENTIONAL ROOFING ASSEMBLY (CRA):

The roof membrane is located on top of the insulation and therefore subject to destructive elements such as ultraviolet degradation, thermal cycling, hailstone impact, and other environmental hazards. The vegetated system is loose-laid on a CRA which helps to protect and extend the lifespan of the roofing membrane.

PROTECTED MEMBRANE ROOFING ASSEMBLY (PMR):

Insulation is located above the roofing membrane. A root barrier is installed in between the insulation and roofing membrane to promote open diffusion and ensure the top surface of the insulation has a ventilating air space. The roofing ballast above the insulation becomes part of the system and acts like the drainage layer. Contact us for other roofing assemblies.

PERMIT APPROVALS AND GREEN ROOF DECLARATION

Next Level Stormwater Management provides a Survivability Report with details about the success of our projects to assist with permit processes, such as the City of Toronto permit application. For more general info or help with other municipalities, please see FAQ or contact us.
