Total accountability.

We take full responsibility for design, materials, and installation workmanship, removing risk and uncertainty for building owners and estates teams.

Single Point Guarantee

Applications

Green Shield systems support diverse environmental priorities across commercial, residential,
education, and public sector developments.

Biodiversity enhancement

The sedum planting layer contributes to biodiversity objectives and can support planning and ecological strategies.

Stormwater management

The substrate and vegetation layer retain and release rainfall gradually, contributing to the management of roof-level surface water.

Thermal performance

The vegetated roof build-up helps moderate temperature fluctuations across the roof assembly, contributing to the performance of the waterproofing system.

Waterproofing protection

The growing medium and vegetation layer provide additional protection from direct UV exposure and thermal cycling across the waterproofing system.

Green Shield system configurations

Four Green Shield configurations are available to suit different roof designs, performance objectives, and maintenance strategies.

Solar PV

Combines an extensive sedum roof with integrated solar PV, allowing renewable energy generation and vegetated roof construction within a single roof build-up.

  • Integrated extensive green roof and solar PV
  • Elevated mounting system above vegetation
  • Compatible with coordinated roof design

Sedum

An extensive green roof system using established sedum planting, providing a lightweight vegetated roof suitable for a wide range of refurbishment and new-build applications.

  • Extensive sedum planting system
  • Lightweight roof build-up
  • Low maintenance planting strategy

Wildflower

An extensive green roof system incorporating a selected wildflower planting mix, specified where biodiversity objectives and habitat creation form part of the project design.

  • Native and perennial planting selection
  • Supports biodiversity and ecological strategies
  • Extensive roof build-up with managed maintenance

Storm Defence

Storm Defence combines an extensive green roof with a blue roof attenuation layer, temporarily storing rainfall and releasing it at a controlled rate as part of the building’s drainage strategy.

  • Blue roof attenuation beneath the vegetated layer
  • Controlled discharge to the drainage network
  • Designed for developments with surface water constraints
