New developments for intensive green roofs

April 27th, 2010

Wallbarn has developed a new drainage membrane to better drain and sustain intensive green roof systems.

Protecto-drain 60P gives a larger water reservoir, holding 20 litres per m2, and gives a greater flow rate. Much thicker substrates can be installed (up to 900mm), allowing trees, shrubs and thirsty plants to be planted.  Always remember an automatic irrigation system is essential, though.
