| The challenge: flat green roofs and roof gardens –
ISO-DRAIN nature 20 PG meets the challenge head-on
with 20 mm high dimples and 3 mm drainage apertures
along with premium-grade geotextile lamination on its
upper surface. The sheet combines three essential
components in a single product: upper filter mat, ample
water storage volume and a high-performance drainage
layer. ISO-DRAIN nature 20 PG is an ideal base sheet for
extensive green roofs, i.e. those designed to do without
regular maintenance. |
