The GRO Bipolar Best Practice Design Guide July 24
This Best Practice Design Guidance has been produced through the GRO Technical Committee and specifically by the GRO BioSolar Working Group, a WG consisting of GRO Manufacturer, Supplier and Contractor members with expertise in the field of Solar and Green roof systems.
This guidance is about the use of building boards of limited- and non-combustibility in flat roofing. The document offers guidance for the use of building boards of limited- and non-combustibility as structural flat roof decks; abutment wall upstands (including parapets); and acoustic mass layers, thermal barriers, cover boards and/or recovery boards in flat roof overlays.
2026 has been a mixed bag weather wise, but it’s safe to say we’ve had more than our fair share of rain and grey miserable skies. It’s very easy to get carried away when the sun finally makes an appearance.
NFRC have collaborated with The Bat Conservation Trust (BCT) to produce guidance for bat and roof risk management and considerations during roofing works.
