System: Rooflogic Fibertherm MSR

The Project

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.

The structural rail assembly allows the Fibertherm MSR system to use Elite Glass Wool low density insulation in the most efficient way, eliminating the thermal breaks and cold bridging that is an inherent flaw of traditional roof assemblies.

This system allowed us to close in the top roof and have it weathertight within half a day so work could continue below. The rails, insulation and top skin are then installed from the comfort of a solid surface rather than balancing on purlins.

The Roofing Project

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.

The Enviroclad was installed in continuous lengths which minimises joins. This is the benefit of Enviroclad being 3.6 wide and coming in 30 metre rolls.

Because the building is so hard to access we opted for Colorcote Magnaflow which is the marine grade system from Colorcote. This will ensure that this building will not need to be re-roofed for many years.

System: Nuratherm Warmroof

The Project

The council owned Palmyra apartments had a major overhaul which included a new Nuratherm Warmroof.

The existing roof had no fall and was ponding water. Fall was installed to new outlets, new ply was fitted and then we installed the Nuratherm Warmroof over the top.

You can see in the pictures the great difference this made aesthetically. What cannot be seen are the huge thermal benefits the residents can now enjoy.

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.

Completion Date: March 2019

The Roofing Project

The existing roof was a mixture of Profiled metal and Membrane on a ply substrate and concrete slab.

To achieve the required insulation values Dunedin Roofing specified Viking Warmspan. This Warmroof system is made up with a profiled steel substrate, intergrated vapour barrier, two layers of 50mm PIR insulation installed providing a continuous thermal rating of R4 across the roof, eliminating the condensation issue that was occurring with the previous roof system.

The project involved the removal and recycling of all the existing materials, upgrade of the structure under the roofing, installation of Warmroof, new parapet flashings and installation of a permanent roof safety system to the perimeter.

Completion Date: 2014

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.

The new facility features a new potting and propagation area, office spaces & teaching spaces and a glasshouse which hosts 8 fully automated habitats.

This complex project involved intricate detailing and flashing work and we are very proud of the end result.
