DESCRIPTION
Radmat D40 is made of high impact recycled polystyrene. It stores up to 23.3 l/m2 of water and will therefore provide a good supply of water for all plants within an intensive or extensive green roof. With a maximum crush resistance (filled) of 625 kN/m2 green roofs can easily be combined with areas of hard landscaping.
The three-level drainage system with integrated branch drains ensures a high drainage capacity. Radmat D40 is supplied in sheets 40mm deep and is resistant to compression from 280 kN/m2 (unfilled) to 625 kN/m2 (filled).
