Green roof

Success story

Xeroflor brings a greener, quieter world to Singapore’s children

PROJECT OVERVIEW

How Xeroflor’s exceptional lightness made a green roof possible for a Singapore daycare centre – in the face of location, access and construction challenges.

Structural loading ruled out standard solutions

As part of a bold, garden city transformation, Singapore’s Housing & Development Board wanted to retrofit a green roof to a daycare centre in the Punggol housing estate. However, the steep slopes, multiple gradients, difficult access and location – atop a six-storey car park – presented numerous installation and maintenance issues. Meanwhile the structural loading of the metal roof itself meant it would struggle to support the weight of a standard green roof system.

 

Ultra lightness eases installation and maintenance

The combination of our XF301 pre-vegetated mats and XF159 water retention fleece is outstandingly lightweight, even when fully saturated. It solved the project’s challenges. The roll format enables it to be quickly laid - even around complex contours - and easily retracted for inspections and repairs. The use of locally grown, low-profile tropical plants makes our pre-vegetated mats heat and drought resistant, and easy to maintain.

Our solution helped the HDB to achieve its goals of lowering the centre’s interior temperature and reducing air conditioning use, as well as cutting noise levels for the children. XF301’s ‘instant green’ effect improved the view for neighbouring homes, with a wide mix of plants providing interest throughout the year. It also reduced reflective glare. Finally the minimal maintenance inherent in our Xeroflor system has made it the ideal candidate for Singapore’s ambition to ‘green’ its existing housing stock.

The benefits of our solution

  • An XF301 pre-vegetated mat, installed over a XF159 water retention fleece, weighs only 50 kg/m2 when fully saturated.
  • It is one of the lightest weight systems on the market. A Xeroflor green roof can be fitted where competing products would be too heavy.
  • All components are in a roll format. They can be easily rolled out and secured on sloped roofs and around complex shapes.
  • Installation is simple as there is no loose growing medium.
  • The plants used in our pre-vegetated mats are chosen to be heat and drought tolerant. They have a low profile that requires very little trimming or mowing.
  • Their variety ensures visual interest throughout every season, and enhances diversity.
