Case study: retail

ALDI


Application for walls and car park soffits:
From the early projects like Auburn to Warriewood, a PIR board was used and shown to be equal or better than phenolic thermal laminate.

Problem

Car park soffit application – architects and builders wanted to install a simple rigid board that would not be a long-term eyesore.

Theory

The product needed to comply with the BCA/NCC for fire as an exposed lining. XPS and EPS were not acceptable because they were thermoplastic rather than thermoset. Early projects only required AS1530.3, migrating to AS3837, AS9705 and eventually migrating to AS5637.

Application/Solution

Early projects used rigid boards to minimise the condensation issues under the freezer and the finish looked just like concrete.

Unlike EPS, it was more tear resistant and provided the required fire performance. Unlike phenolic, it didn’t suck water when the rain seeped in from penetrations in the slab during construction.

We used PIR, which creates less smoke than EPS and polyurethane boards. However, claims from phenolic suppliers that the product is around four times less smoke than PIR need to be verified. We have evidence that PIR has the same performance or better than phenolic. To find out more, search for ‘The burning truth’ on YouTube.

Coles


Coles were looking to have an exposed lining in their retail space.

Problem

What products would comply with Specification C1.10 of the NCC/BCA for exposed linings with a white or off white finish.

Theory

The BCA was moving away from AS3837 because foil faced products like EPS and blanket were achieving the result on a small scale sample or didn’t have test data.

Application/Solution

Using DOW Thermax it was easy, there was no secondary laminate required, nor did the installation look like a pin cushion. A benefit that followed for Coles was having a product that would comply to US underwriters use third party testing and certification services like FM, UL to meet loss prevention standards of quality. FM4880 was one example of the benefit.


Westfield


As part of the installation at Westfield's Macquarie Centre, the new Coles required FM4880.

Problem

An alternate product was installed and the cost of rework devoured the savings due to choosing a less tested material.

Theory

It's important to check the test certificates presented. Laboratories will provide a verification service to confirm documents have not been altered. Using authorities based in Australia and New Zealand makes it easy to check.

Application/Solution

No solution could be engineered. The non-compliant material was ripped out and the correct product installed. Not many people had read the specification and the project was simply looking to replace the semi-rigid with our product. Unlike the phenolic alternate solution, we knew the site was going to use FM Global.
