A commercial building was to be constructed in Dunedin with a very tight deadline that almost seemed impossible to achieve. The walls were clad entirely in Dimond VRib whilst for the roof Rooflogics Fibertherm MSR was selected.

Unlike other traditional metal roof assemblies the Rooflogic Fibertherm MSR system provides high levels of thermal performance and is designed to mitigate condensation risk which is a huge factor in the lower South.

At the heart of the Fibertherm MSR system is the patented structural rail assembly that is used to separate the outer skin from the internal liner deck.

Dunedin Roofing was selected to replace the aging roof at Dunedin’s Toitū Museum. This large project required new roofing and new box gutters, including ply substrate.

We completed this job under a tent and the museum remained open to the public for the duration of the project.

For such a large building there were undersized outlets, so these were all upgraded into larger proprietary Viking outlets including new overflows.

Dunedin Roofing Systems and Stewart Construction were selected to design and supply a solution for an existing roof at the Dunedin Public Art Gallery.

It had problems with water ingress and was also poorly insulated and did not provide for safe working on roof mounted plant.

The roofing system used on this project was: Viking Warmspan and Warmroof, 2 layers of 50mm Polyiso achieving R4 thermal rating and Viking Enviroclad TPO as the waterproofing layer.

The Project

The new propagation and nursery facilities on Lovelock Avenue are the biggest investment in the Dunedin Botanic Garden’s history. Soon after the turn of the century the Dunedin City Council identified the old plant nursery facility was both ageing beyond repair and inefficient. The environmental management systems became less energy efficient and inadequate to produce the variety of plants needed by the Garden.
