Delta Membranes Systems - DELTA® Floraxx Top – Green roofs

Water-retaining drainage sheet for perfect green roofs. Innovative octagonal dimples for outstanding compressive strength. One sheet for drainage and water storage. Easy and quick to lay out straight from the roll.

DELTA®-FLORAXX is used on inverted roofs to drain water away from insulation panels under accessible surfaces. Thanks to its breathable perforation and its dimples, water and air may circulate freely on the underside so that no co-herent film of water can form on the insulation. This sheet may be used in extensively planted as well as in accessible inverted roofs covered with paving stones or slabs.

This is the best green roof membrane on the market, not only does it drain surface water away in controlled manner but also irrigates your garden / green roof.

DELTA®-FLORAXX TOP has an integrated filtration layer (geotextile), BIO- TOP. Soil may be spread directly on top of it, to be planted according to your choice.

There are two types of green roofs, extensive and intensive depending on the depth of planting medium and the amount of maintenance they require.

Extensive green roofs
Extensive green roofs support a small amount of soil and vegetation and are designed to be virtually self-sustaining and maintained approximately every half a year. Extensive roofs are usually only accessed for maintenance.

Intensive green roofs
Traditional roof gardens, which require a reasonable depth of soil to grow large plants are considered intensive because they are labour-intensive, needing irrigation, feeding, and other maintenance. Intensive green roofs are likely to consist of anything from kitchen herbs to shrubs and small trees.
