Viking WarmSpan was specified to replace the roof of Auckland's 5-star Hilton Hotel, with Viking Torch-On specified as the waterproofing layer.
Settled on Auckland’s waterfront on the end of Princes Wharf, is the eight-storey 187-room 5-star Hilton Hotel.
It was in need of a new roof to replace the old metal one; only this time, the client was looking for more thermal efficiency along with the usual requirements for water tightness, salt spray corrosion resistance, durability and the ability to withstand high wind pressure. The decision was made to have a membrane roof installed.
The building roof design was such that the large ceiling void with its myriad of reticulated services did not lend itself to a typical ‘cold roof’ insulation system where glass wool insulation had proven problematic; so installing a warm roof system was the preferable option.
It was also critical that the roof was to be replaced without upgrading the original steel portal frames or purlins, as the extra time and cost to replace those would have been prohibitive.
It was important to the architect, Babbage Consultants Ltd that this luxury hotel took advantage of one of New Zealand’s simplest, most energy-efficient and cost-effective warm roof systems — Viking WarmSpan. Additionally, being avid fans of bitumen-based membrane products because of the service history in New Zealand, Viking Torch-On was specified as the waterproofing layer.
