  1. 1. Jiffy Green Roof Substrates Pushing architectural boundaries, encompassing nature. Certified conforming according to the new RAG Green Roof label BackgroundOne of the most valuable features of green roof infrastructure is that itgenerates a wide range of social, economic and environmental benefits.As we moved to the 21st century, green roofs can address many of thechallenges faced by urban residents.The following describes some of the significant benefits of green roofs. Mahler building, Amsterdam (a)1. Energy SavingProvide shade and remove heat from the air through evapotranspira-tion, this in turns helps to reduce heat from the surrounding area, aswell as decreasing the amount of energy required to cool the building.2. Stormwater ManagementReduces the amount of stormwater runoff and also delays the time atwhich runoff occurs, resulting in decreased stress on sewer systems atpeak flow periods. With green roofs, water is stored by the substrateand then taken up by the plants from where it is returned to the atmos- Mahler building, Amsterdam (b)phere through transpiration and evaporation. 1

Roof Membrane Protection and Life ExtensionHelp to protect roofing membranes from extreme temperaturefluctuations and negative impact of ultraviolet radiation. Green roofs willeasily double the life span of a conventional roof, and thusdecrease the need for re-roofing. These are direct operational cost savingsto the building owner. Mahler building, Amsterdam (c)4. Sound InsulationThe combination of soil, plants and trapped layers of air within greenroof systems can act as a sound insulation barrier. Sound waves are ab-sorbed, reflected or deflected. The growing medium tends to blocklower sound frequencies while the plants block higher frequencies.5. Fire ResistanceSlow the spread of fire to and from the building through the roof,particularly where the growing medium is saturated. Mahler building, Amsterdam (d) 2

Reduce "Urban Heat Island Effect" (*UHI)Help to reduce building heating and cooling costs due to buffering effectof the plant matter and soil. Green roofs are an important component inan overall strategy to offset the negative impacts of "Urban Heat IslandEffect". Like urban forests and reflective roofing surfaces they absorband deflect solar radiation so that it does not produce heat. Mahler building, Amsterdam (e)7. Generate Aesthetic BenefitsTurn wasted roof space into various types of amenity space for buildingoccupants, improving quality of life.*UHI - describes built up areas that are hotter than nearby rural areas. UHI can affectcommunities by increasing peak energy demand, air-conditioning costs, air pollution, heat-related illnesses and water quality. 3

Certified conforming according to the new RAG Green Roof labelBenefit from Jiffys experience in their productionand supply of specialized substrate for roof gardensSustainable construction is becoming an increasingly important subject within the buildingsector. Sustainability of buildings is getting more required from both consumers as the buildingsector. Jiffys Green Roof Substrates for roof gardens greatly buffer the flow of rainwater sothat drains have more time to transport the water. In addition, roof gardens provide a significantreduction in particulate matter as they clean the air. Even more, because they help insulatebuildings providing cooling in hot weather and reducing the “Urban Heat Island Effect”. Singapore 4
