DCT-R09-3
EXTERNALLY INSULATED GREEN ROOF WITH RAINWATER STORAGE, DRAINAGE AND ROOT AERATION (DC20-R)
Green roof, externally insulated with a moisture resistant high compressive strength XPS insulation, located below the waterpoofing membrane barrier to maintain the roof slab at a stable indoor temperature. The insulation is weighted down by a green roof system which includes a combination of geotextile layers that offer rainwater storage, drainage, root aeration and protection of the waterproofing.
