Floratec FS75

Floratec FS75 is a lightweight drainage and water storage board, manufactured from 100% recycled, CFC free, expanded polystyrene, used mostly in extensive and intensive green roof applications. The product allows aeration of the substrate; evaporation of stored water and multidirectional drainage on the underside. Can also be used on flat roofs, with little or no drainage and on sloping roofs up to 20°.

Application:

Install by loose laying directly onto the root resistant membrane (overlaid with a moisture resistant mat on sloped roofs only). The larger 75 x 75 mm box sections must be uppermost when installing on slopes, whilst the 35 mm diameter water storage holes must be uppermost when used in horizontal applications. Butt joint the boards together. Panels can be cut with a heavy duty knife or a small toothed saw to fit around protrusions. On horizontal applications overlay completely with an appropriate filter sheet and substrate. On sloped roofs, use the filter sheet at perimeters and around protrusions only.

Where slopes exceed 15°, a JEG anti-erosion mat must be used in conjunction with the substrate.
