By re-specifying with Knauf’s SonaRock during a refurbishment of Camberwell Grammar School, the design team cut the amount of material by a third while reducing the need for ongoing maintenance.

Project architect Robert Tedesco, of Peter Crone Architecture, explains he switched to SonaRock during an advanced project stage after recognising an ongoing cost saving for the client, and witnessing superior impact and acoustic performance.

“We were already moving into the construction phase with another product when we decided to go with SonaRock,” Tedesco says. “Not only could we recognise a cost saving and a way to reduce ongoing maintenance, but the board had better impact and acoustic performance.”

For Tedesco, ongoing maintenance was a key consideration for the project. He explains that a number of standard plasterboard walls throughout the school were being repaired or completely replaced on a regular basis.

“Repairs come at quite a considerable cost so even when it’s just a few instances they really add up,” he says. “Once we explained this, the school’s property manager also saw the benefi t of running with a sturdier product.”

SonaRock helped to consolidate and reduce the amount of material needed for the project by as much a third, according to Tedesco.

“On previous jobs we have had two, three or even four types of plasterboard,” he says. “But with SonaRock we were able to consolidate that down to one.”

Tedesco adds that his team established a good rapport with Mark Micallef, National Project Manager at Knauf, who helped alleviate concerns the contractor had about working with a new product at a late project stage.

“With Mark’s help, we were able to put the contractor in direct contact with Knauf to sort questions he had about working with SonaRock,” he says. “Mark also took us to see a number of projects currently under construction.”
