Bruce Mason Centre
Challenge
The roofing membrane on the iconic Bruce Mason Theatre in Takapuna had reached the end of its usable life and begun to leak... but 'the show needed to go on'. Ian Hay, senior architect at GHD, sought advice from Viking Roofspec, whose technical team was engaged to verify the existing roof's integrity and then propose an appropriate solution.
The solution needed to meet specific criteria: provide a watertight finish; stiffen the existing ‘bouncy’ substrate; work around shows and weather; cope with a large ventilation system on the roof; resolve ventilation in the roof cavity; and adhere to compliance issues with the historic roof structure.
Solution
One system shone above the rest - The Viking WarmRoof in white.
An installation programme was then devised to meet the timetable requirements of the theatre. The Viking WarmRoof System was perfect for this project due to:
-
The ability to overlay the old membrane, so no need to open the roof and expose the interior. This also meant reduced wastage, labour and environmental costs as the current membrane did not need to be removed and dumped;
-
No need for roof cavity ventilation seeing as Warm Roof takes the dew point to the outside of the building;
-
The polyisocyanurate insulation boards would add both energy efficiency to the building and structural integrity to the roof substrate.
Result
'The show went on' as visitors to the Bruce Mason Theatre relaxed and enjoyed the performance, whilst being protected from the elements by a new Viking WarmRoof. Added assurance was also provided by this project qualifying for a Viking Full System Warranty, which covered the product and installation process in one document for a 20-year period.
