APPLICATION OVERVIEW

Key considerations when designing green roofs include overall weight of the system to ensure it can be supported by the roof structure, in addition to water retention capability of the system to minimise stormwater run-off.

Our Mineral Wool green roof growing mediums help to produce innovative extensive green roofs which support sedum, moss, herbs, grasses and other vegetation where Urbanscape® low or no maintenance is required.

Why Mineral Wool?

  • Mineral Wool provides the best combination of thermal, fire safety and acoustic performance.

  • Mineral Wool substrates can be 8-10 times lighter than regular Green Roof substrates, meaning they can be installed onto lightweight constructions where traditional systems are otherwise not possible.

EXTENDED ROOF LIFE

Green roofs have been shown to triple the life expectancy of the roof.

The underlying roof materials are protected from mechanical damage, ultraviolet radiation and extreme temperatures, which results in reduced maintenance and
renovation costs.

 

RAINWATER RETENTION

A major advantage of green roofs is the reduction of storm water run-off, which leads to a decrease of the burden on sewer systems by 70-95% in summer.

Green roofs have influence on cost reduction due to low or no need for rain-catching cisterns and similar equipment which is usually used for storm water management.

CO2 REDUCTION

Green roofs help to reduce the amount of CO2 in the air, which is considered one of the most important causes of global warming. 1m2 of a green roof can absorb 5 kg of CO2 yearly. 1m2 of green roof can absorb the same quantity of CO2 as a regular car would emit during an 80km drive.

CLEANER AIR

The plants on green roofs can also capture airborne particles such as smog, heavy metals and volatile organic compounds from the local atmosphere which has a positive
effect on air quality and health of inhabitants. Researchers estimate that 1m2 of a green roof can help to absorb 0.2kg of airborne particles from the air every year*.

 

NOISE REDUCTION

A green roof system provides good sound insulation, keeps the living space quieter and creates more pleasant surroundings in urban areas, and it contributes to noise
reduction in large cities, near industrial areas and airports.
