Hobsonville Point Primary School

Dimondek 630 on Hobsonville Point Primary School

The release of government owned land near the Hobsonville Airbase in Auckland’s North- West, has allowed for the development of Hobsonville Point as one of Auckland’s newest satellite communities. To meet the new community’s needs a primary school was needed.

Designed by ASC Architects the project had very specific design requirements for the roof:

  • Provide maximum light transmission
  • Reduce the noise coming through from rain
  • Provide minimum thermal energy loss

7,500 lineal metres of Dimondek 630 was specified for the roof in runs up to 47m long, being a concealed clip system there are no penetrations through the roof – eliminating leaks.

Too meet the light and thermal loss requirements the architects, Hawkins and mechanical engineers worked with Dimond Roofing, Ampelite and Kiwi Roofing to design a ThermRline skylight system. The solution was using a Durolite sheet formed from a Dimond Roofing 3 ribbed Styleline profile, with modified side ribs to lap to the Dimondek 630, over a second layer of matching polycarbonate sheet. Light wells including further layers of flat plastic sheet were constructed below the skylight to disperse the light and minimise rain noise.

The lighting strip widths were critical to the floor plan layout to provide natural light exactly where it was needed. The top natural lighting strips run from ridge to eave and are blanked out with building paper in areas not requiring natural lighting The Natural lighting strips have been placed in each of the classrooms so that the children’s desks are exposed to maximum amount of natural light.

Other features of the job included the use of 2,000 lineal metres of Dimondek 630 for wall cladding and the use of architecturally designed aluminium flashings as well as a unique gutter with custom made brackets, all of which has galvanised the team to forge the right solutions for the site.
