When every floor covering is hard, acoustic performance becomes critical. Read more about how PhoneStar Lite achieved exceptional acoustic performance at Mascot Street.
Built in the 1800s, 79 Princes Street in Dunedin has recently undergone a thoughtful conversion into modern apartments. While rich in character, the building’s original lightweight timber midfloors posed a significant challenge — excessive noise transfer between dwellings.
To meet New Zealand Building Code Clause G6 requirements, the project required an acoustic solution suitable for an existing timber joist midfloor with a fire-rated ceiling below. Floor height was a critical constraint; raising levels would have meant altering doors and compromising ceiling heights.
The team selected Phonestar Lite, a thin acoustic board system designed to achieve G6 compliance on timber substrates without adding unnecessary bulk.
PhoneStar Lite's slim profile allowed for a straightforward installation while maintaining existing thresholds and proportions — a major advantage in a heritage conversion. The system was compatible with multiple floor finishes, including timber, tile, and carpet.
