Roof membrane DELTA®-FLORAXX

surfaceHDPEHDPE

Diffusible protective and drainage membrane with water storage function. Surface drainage and water storage in one. Ideally suited for use on green as well as on inverted roofs. The dimpled membrane is safe for drinking water, resistant to chemicals and does not rot in the ground. Advantages Large water reservoir of approximately 7 l/sqm DELTA®-FLORAXX stores rainwater. This is why it serves as a water reservoir for dry periods. Excess rainwater can run off through the perforation holes punched in the dimpled sheet and can be drained on the roof waterproofing between the knobs. 80% higher compressive strength Thanks to the octagon knob with reinforcing ribs, it has an approx. 80% higher compressive strength than standard nubs. Vapour-permeable Thanks to its perforation, the dimpled membrane is open to diffusion (with an SD value of approximately 0.4 m) by enabling unhindered drainage as well as vapour pressure relief. This prevents a closed water film from forming on the insulation and damaging it. Logistics DELTA®-FLORAXX FLAT is also available in the format 2.35 x 1.00 m as sheet goods. 200 pieces and/or 470 sqm per industrial pallet.
