Used on inverted roofs to drain water from insulation panels and under accessible surfaces, Delta-FLORAXX’s breathable perforation and dimples allow water and air to circulate freely on the underside. This means no coherent film of water can form on the insulation.
With Delta-FLORAXX TOP (a second option in the collection); there is the additional benefit of a filtration layer, eliminating the need for a separate laying operation.
Ease and speed of installation is a huge benefit with both of these products, the sheet size of 20m x 2m for Delta-FLORAXX, while the FLORAXX Top option is supplied in 10m x 2.1m sheets (the extra 100mm geotextile width allows for overlap).
Capable of storing 7 litres/m2 of water as a reserve for periods of drought, Delta- FLORAXX/FLORAXX TOP are breathable and water permeable thanks to the perforation between the storage dimples. Other features include a compressive strength of 200kN/m2 thanks to its innovative octagonal dimples.
With green roof construction becoming increasingly popular in the UK, Delta-FLORAXX is the perfect solution to bring the combination of strength, effective drainage, water storage and – with the FLORAXX-TOP option – filtration in one, easy to apply product.
To complement these drainage sheets, the company also offers Delta-Bio-Top protection Barrier – a protective layer confirming to the FLL guideline for green roofs. This is supplied in rolls of 1.5m x 25m.
