Acoustic cavity sliding performance designed for 64mm stud framing. The Silencio Celtic 64 combines Criterion's purpose-built aluminium cavity system with the Barwon Narrow Stile door to deliver an Rw 42 rated solution, ideal for healthcare, education, commercial, and multi-residential projects where acoustic separation and space efficiency are equally critical.
The system delivers tested acoustic performance (Acoustic Report: TL 845-14) without compromising on the compact footprint that makes cavity sliders the go-to choice for modern fitouts.
Every Silencio system is tested as a complete assembly in a nationally recognised laboratory — leaf, frame, seals and threshold together — and rated to AS/NZS ISO 717-1. The figures below are the tested laboratory ratings for each configuration we supply.
| Configuration | Rating |
