StormCap+™ (Ontario Only)

StormCap+™ (Ontario Only)

Superior – Up to 10 IA

On site water balance with superior initial abstraction (IA)

Key features

10 IA with pre-grown system

  • Improves on site water balance (TGS WQ 1.1) with superior initial abstraction (IA)
  • Superior water-retaining system that’s pre-gown and instant green with 85% foliar coverage
  • Hydro Blanket is non-petroleum, formaldehyde-free alternative. Acts as a water reservoir, holding up to 90% of its volume in water reliably throughout the lifespan of the roof
  • Growing medium stores water and improves thermal performance
  • Ideal source control BMP stand alone or as part of a treatment train
  • Low maintenance

Stormwater Management (SWM)

Stormwater Management (SWM)

  • Specialized, instant green, stormwater retention system
  • Hydro Blanket filters particulates and cleans the water
  • Source control BMP either stand alone or as part of a treatment train

High Performance

High Performance

  • High water storage reduces plant stress between rainfall events
  • Growing medium stores water and improves thermal performance
  • System parameters can be customized to meet SWM requirements

Low Maintenance

Low Maintenance

  • Mature, established sedums are hardy, heat & drought tolerant
  • Low-profile plants do not require any mowing or trimming
  • High built-in water storage reduces irrigation needs

The Bioberm™ Add-On

A cost-effective option to enhance biodiversity on the StormCap™ 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.
