Bondor’s insulated PIR core roofing MetecnoSpan® was selected for the project due to the products’ speed of installation, short manufacturing lead times from Melbourne, as well as comprehensive warranties and meeting the high thermal performance requirements for both R values and air leakage testing.

PPC project manager, Cameron Pryde, said the long spanning MetecnoSpan® insulated roof product was an all-in-one solution that reduced labour and the project install time with a product that includes the roof, insulation and a prefinished ceiling in a single installation. This is not normally achieved with a traditional built-up roof system which consists of multiple layers of roof sheeting, bulk insulation on a foil and mesh ceiling. The building’s thermal requirements were easily achieved with MetecnoSpan®’s extremely high R5.0 thermal rating.

“Locally made long roof panel lengths were also a great benefit as PPC used up to 20m roof panels which enabled us to install more square metres per day , helping us meet the tight installation timeline,” he said.

In addition, to meet the building’s thermal performance requirements, traditional box gutters required significant insulation, as a result insulated gutter system was fabricated locally using the MetecnoPanel® insulated box gutter system, which eliminated the need heat welding and allowed speedy installation of long 12.5m lengths. The interface between the gutters and the roof end lapping system created an air tight seal where thermal leakage can typically occur.

After installing the product and air testing the entire building, the MetecnoSpan® and MetecnoPanel® passed with ease.
