How Xeroflor’s exceptional lightness made a green roof possible for a Singapore daycare centre – in the face of location, access and construction challenges.
one of the lightest green roof systems on the market
Singapore National Parks research
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.
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.
An effective green roof drainage mat is critical for a successful installation, and brings environmental benefits.
Stabilises green roofs – no need for hydromulch or wind netting, and you have flowers and foliage all year round.
Vegetation carriers support seedlings, stabilise the soil and minimise erosion, and you can harvest them in rolls.
