What is a Green Roof?
A green roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.
Types of Green Roofs?
Green roofs are generally categorised into the following:
- Intensive ≥ 300 mm growing media, irrigation with a wide variety of shrubs, grass and tree species on slopes
- Extensive ≤ 300 mm growing media, minimal irrigation with hardy, low growing plant and ground cover species on slopes
Advantages of Green Roofs
Green roofs serve a number of benefits for a building, these include:
- Improved property value – Planted roof areas increase the ‘permeable to hard-stand’ ratio on building sites and allow the creation of usable commercial and recreational roof gardens and terrace areas.
- Improved environment – plant species minimise greenhouse gas emissions and pollutants are absorbed by growth media particles and plant species provide a habitat for a diverse range of fauna.
- Reduced energy costs – radiation is minimised and growth media insulation ensures cooler buildings in the summer and warmer buildings in winter.
- Reduced maintenance – roofing materials and waterproofing membranes are protected against UV degradation, hail and storm conditions.
- Better sound protection – inter level noise transfer is minimised.
- Water retention – precipitation is retained on site reducing run-off to storm water systems.

What is a Green Wall?
A green wall is a wall, either free-standing or part of a building that is partially or completely covered with vegetation and, in some cases, soil or an inorganic growing medium.

How does a Green Wall work?
A green wall is comprised of vertical modules assembled from high strength lightweight structural panels, incorporating interlocking snap-on clips for easy assembly. The front panel has a unique grid to facilitate planting of up to sixteen plants per module.
Green wall modules contain a geo textile liner into which is placed a suitable planting mix. The modules are pre planted in a nursery environment to allow proper establishment to occur before installation on site.
The modules are either mechanically fastened on walls or inserted into freestanding steel support racking structures. They also include drip irrigation systems that are positioned at appropriate intervals, depending on wall heights. Collection trays may be positioned, at ground level to allow overflow water to be discharged or recycled.
Types of Green Wall
Green walls are generally categorised into the following:
- Interior Walls
- Exterior Walls
- Free standing Walls
- Building Facades
Advantages of Green Walls
Green walls serve a number of benefits for a building, these include:
- Added site value
- Improved heat insulation
- Reduced sound transmission
- Enhance air quality
- Reduced storm water run off
