With the constant progression of urban growth and increased levels of density in cities across the world have created, and continue to create, “urban jungles”. Such a concentration of structures and people can often lead to a sense of oppression, stark, noisy, unnatural blocks of concrete and glass. Aerial shorts of cityscapes show up vast swathes of flat roof and concrete decks – empty, ugly, impermeable wasted space.

How do we address this problem?

With Green Roofs:
Green roofs and living walls are a great way of providing an attractive, useful, environmentally friendly open space on otherwise ‘lost’ flat roofs and podium decks.

Green roofs can improve the local environment by providing wildlife habitats. Wallbarn encourage bees and other wildlife with a diverse selection of wildflowers and vegetation. Click to see Wallbarn’s Wildflower and Grass Species List.

Additional benefits of green roofs not always considered by developers:

• Absorbing CO2, pollution and particulates from the atmosphere
• Improving sound and vibration insulation
• Improving thermal insulation
• Reducing the amount and speed of rainwater run-off by around 50% and forming part of a SUDS design
• Reducing the “heat island” effect in built up areas and helping to improve air quality and environment
• Protecting the structure and waterproofing membrane from:
   o UV light and heat from the sun
   o impact and abrasion
   o environmental elements including extremes of temperature
   o plant and bird infestation
• Ballasting inverted waterproofing systems
• Optimising the structural footprint by:
   o Increasing space – providing new and attractive natural amenity areas
   o Adding floor space in often high density developments
   o Adding focal points
   o Decreasing energy costs
   o Increasing value of the development
   o Properties with green roofs sell / rent faster rate than naked buildings
• Making the planning process easier
• Money saving
