Noisy schools are a thing of the past, thanks to new technology that ensures products have high acoustic ratings. But noise insulation isn't just about reducing student noise. For Te Whanau o Tupuranga, it was essential to limit the noise from the air conditioning units installed above the library ceiling.
Jasmax architect Roy Blok, acoustic consultant Curt Robinson of Marshall Day Acoustics, and Julian Huggins, project manager for the main contractor Arrow International, worked together to determine the selection of Parmephon Velum high-performance acoustic tiles. These were supplied and installed by National Construction Interiors Ltd, a company that specialises in acoustic ceiling tiles.
Parmephon Advance acoustic tiles installed by National Construction Interiors Ltd were specified as a cost-effective alternative to boxing the air conditioning units. Company director Igor Ivanov says the tiles, which incorporate white fibreglass tissue, were used with plasterboard panels and high-density insulation.
"This method ensures the air conditioning units can be easily accessed," he says. "It also allows the ceiling to be repaired without great expense in the event of any water damage. But most importantly, the Parmephon acoustic tiles ensure the library and classrooms have a high acoustic performance."
Mr. Ivanov says building the suspended acoustic ceiling in an existing building with exposed roof trusses was a challenge as there was limited space to fit the system. The solution was to secure the acoustic tiles to new plasterboard fixed directly to the existing ceiling.
Julian Huggins says Arrow International regularly works with National Construction Ltd. "We supply specific details of our requirements, including the level of acoustic performance needed, and National Construction Interiors Ltd always has a solution. We rely on the company's expertise to meet all aspects of the design brief with a cost-effective option."
As Parmephon tiles are manufactured from 70% recycled materials, they also meet Tupuranga School's sustainable design requirements. Parmephon Advance acoustic tiles were specified for classroom and library ceilings, and Parmephon Hygiene tiles feature in food technology rooms.
The company also supplied Parmephon Higyn ceiling tiles for the food technology rooms at the school. These tiles provide a washable surface that makes it easier to keep dust at bay, which makes them well suited to food preparation areas, hospitals, pharmaceutical companies and electronics manufacturing. They are also resistant to high humidity.
Parmephon acoustic tiles have high light reflectance and are made from 70% recycled materials, which fits with the school's sustainable design philosophy.
