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

Soilless and lightweight pre-vegetated roof system such as LiteN'Less Classic or XF301 Xeroflor systems on retrofitted wood structure. Retrofit. Residential green roof. Slope.

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.
