Norwich City Council has refurbished the rotunda roof of the Grade I-listed Norwich Castle, using a Sarnafil membrane. The new batten profile and lead-grey-coloured G41015ELF membrane was used to overcome cost and ease of installation issues. A cold applied system was used to secure the membrane, eliminating the need for naked flames on the roof. The project was completed by Briggs Roofing and Cladding of Norwich.
