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