 Green roof system

  • Creates a natural habitat for flora and fauna
  • Aids biodiversity encouraging a wider spread of species in the area
  • Soft landscaping helps to reduce the risk of flooding by retaining large proportions of annual rainfall and reducing rainwater run-off. Particularly useful within Sustainable Urban Drainage (SUDs) schemes
  • Environmental masking blends the building into its surroundings
  • Improved air quality as vegetation assists in reducing both gaseous pollutants and dust particles
  • Reduces urban heat island effect (the difference in temperature between urban areas and the surrounding countryside) through absorption of some of this heat and the natural evaporation of water from plants and soil
  • Reduces building’s carbon footprint through lowering building running costs
  • Reduced construction costs: no requirement for screed on the deck reducing the overall weight imposed, fewer rainwater outlets, decreased rainwater drainage system capacity and a reduced requirement for storm water attenuation within the SUDs scheme for the site
  • Increased life expectancy of waterproofing membranes when protected by green roof landscaping
  • Many local authorities favour planning proposals that incorporate green roofs within the application, particularly if it meets their policies towards providing a sustainable environment
  • Increased property value – roof usage can be maximised for purposes including leisure, and offers unique potential for replacing the land lost to the building’s footprint
  • Noise reduction for the building – green roofs have excellent acoustic qualities for both external sound (up to 3dB) and internal noise up to 8dB)

When constructing a green roof there are some fundemental considerations that determine the system required to support the planting scheme. The key decisions are about access and what the roof is to be used for, is it for nature conservation and biodiversity or aesthetics? How will the area be used and how much maintenance will be possible.

Many Local Authorities in Canada favor planning proposals that help green roofs within the application. particularly if you meet their policies towards green roof design with a sustainable environment, you will get an incorporation in result.

 Through the 4mm thick sapphire lens, Fake Watches a high contrast display greets the eye. There is a choice of either a Replica Rolex blue or gray sun-ray dial. Both boast applied hour markers that have been filled with seven layers Hublot Replica Watches of Swiss C3 Lume, which is also applied to the 120-click bezel and the hands. The importance of low-light legibility cannot be overstated, as it is critically important for a diver to be able to read the time Fake Breitling Watches that has passed since submersion, no matter the conditions.
