Rockwool's Hardrock used in award winning project
An insulation product developed by Rockwool for a refurbishment project at the grade II-listed Barbican Estate in London has helped to secure a national Roofing Award.
The award was presented by the National Federation of Roofing Contractors (NFRC) at the Annual Congress Awards Lunch on Friday 14 May at the Novotel London West hotel in Hammersmith.
Rockwool's Hardrock SPA roof insulation board being installed on the roof of the Barbican Estate in London
The event was attended by more than 500 roofing contractors, manufacturers and others involved in the roofing industry.
Roofing contractor Delomac Roofing won the Single Ply category with the solution to the Barbican refurbishment project which was carried out in partnership with Rockwool, membrane manufacturer Sarnafil, and distributor, SIG.
The roof refurbishment project involved insulation product being installed to insulate the top three storeys in one part of the Estate's buildings, which were being converted from offices into residential accommodation.
The tight radius of the Barbican's barrel roofs required a flexible insulation to ensure the system fitted tightly and effectively around the curved surface.
After designing, fabricating and trialling various alternatives, the team eventually settled on Rockwool's 40mm Hardrock SPA roof insulation board which was installed with Sarnafil membrane, with special grooves cut into the base of the board to allow for bending around the tight radius, fitting the roofs snugly.
