Does the Riefa growing medium meet the guidelines set by the GRO regarding fire resistance?

All of the roofs referred to by the GRO, in fact those manufactured and fitted by the main sponsors of the GRO, are plastic or oil based , whether it be in the membrane or the plastic trays in which the water and granules sit , all these are flammable.

It makes sense when you are using combustible materials to take some measures to limit the initial spread of flame, the GRO/FFL also recommend that fire breaks are installed every 50m2, again to limit the spread of flame.

RIEFA is of course 100% organic , but more importantly, as it is always wet, whilst not fire proof ,it is non-combustible, and therefore non-compliant with the GRO/FFL guidelines in that regard.

We feel that the guidelines should be reviewed. However, as Riefa is not part of the Alumasc/Bauder sponsorship team, we don’t think that will happen soon!
