Green roof systems are becoming increasingly popular for commercial, governmental and private residential buildings for a number of reasons:
Environmental
– In urban areas they help purify the air by converting carbon dioxide into oxygen and by trapping pollutants.
Building performance
– A green roof system helps insulate a building during
both heating and cooling season, which for large buildings can mean considerable savings.
Political
-In the current international climate, it is good practice to actively promote a green image.
Green Roof Systems
Lava Rock is a natural, lightweight volcanic aggregate with a porous structure and rounded particle shape. Pumice is extensively used in horticulture as a growing medium as it improves soil aeration, retains moisture and promotes root growth. As demand for green roof installations increases so does the use of pumice as a substrate in both the intensive and extensive systems. Reasons for this include:
- Improved soil aeration
- Moisture retention
- Long lifespan
- Thermal properties help insulate a building helping conserve energy
- Improves and controls drainage to avoid run off
- Promotes root growth
- Environmentally friendly
- Air quality improvement
- Noise reduction – acts as a sound barrier from industrial units below
