Simplicity done well
Simplicity done well
- Less is more; a practical solution for most applications
- Pre-grown vegetated mats provide immediate results
- Easy transportation, installation and removal with rolled products
- Retractable, if necessary, and re-useable
Retrofits
Retrofits
- Lightweight system that avoids excessive loading
- Effective way to retrofit building for sustainability
- Improve resilience for stormwater runoff and energy consumption
- Reuse existing rooftop for amenity purposes or increased aesthetics
Inaccessible roofs
Inaccessible roofs
- Low maintenance as it requires minimal irrigation, fertilization and weeding
- Minimal plant replacement due to dieback
- Low wind erosion damage
The Bioberm™ Add-On
A cost-effective option to enhance biodiversity on the LiteN’Less green roof system, maximize value, achieve LEED or meet the Toronto Green Standard Native/Biodiverse requirements. BioBerm™ is a multi-strategy design technique approved by the Design Guidelines for Biodiverse Green Roofs.
Unique Design
Sloped, rounded, pyramid-shaped, LiteN’Less™ easily adapts and conforms to various roof designs. The sedum blanket and premium base layers are fully customizable and can be easily cut to fit any shape and design.

Engineering Green Roofs for CoV’s Rainwater Management Plan
Green roofs play a key role in the City of Vancouver’s (CoV) new simplified rainwater management (RWM) requirements for new Part 3 buildings that took effect on Jan 1. We will learn how to design green roofs to help meet CoV’s retention/detention requirements and when upgrading to a blue-green roof can increase ROI.
Engineering Green Roof Systems to Optimize SWM 2.0
2.0 is a deep dive into the latest stormwater retention and detention technologies. Learn to use modeling to meet water balance and quantity control targets through initial abstraction and irrigation water reuse. Recognize opportunities and limitations. Case study demonstrates performance and cost savings.
Strategies to Meet Policy & Design Goals in Toronto
Check off multiple requirements set by the Toronto Green Standard (TGS) & Wet Weather Flow Management Guidelines (WWFMG). Success requires collaboration between architect, landscape architect & engineers, as well as understanding components, their functions & selection criterion to achieve specific goals.
