The project involved the construction of a new archive storage and office facility for New Zealand Archives.  A RoofLogic system was specified for the main storage building where high levels of thermal performance and absolute weather-tightness were critical in maintaining a strictly controlled internal environment for the new facility.

RoofLogic proposed a system with 100mm of high performance RL PIR Insulation Board.  RoofLogic specified its standing seam profile – Eurolok – which was roll formed on site to the precise, long lengths required and then installed with concealed fixings so that the roof had no laps or penetrations. 

A previous archive facility that had been built with a composite insulated panel roof had performed poorly in respect to weather-tightness so the architect chose the RoofLogic system complete with a site run standing seam profile to guarantee weather-tightness on this critical facility.

System Benefits
  • Excellent thermal performance and verified system hygrothermal performance.  The dangers of traditional “cold roofs” and the inability to manage condensation risk has been well documented on projects like this.
  • Roof ensured internal temperature could be maintained at precise levels.
  • Completely non-penetrated roof profile with no end lapping of sheets which would be required with a composite panel roof.
  • Accuracy and ease of installation with use of site run top skin profile.
