AT40 is an acoustic timber door for rooms where conversations need to stay in the room, a tested rating held in a standard-thickness leaf, so the opening itself stays conventional.
Specify it where a room needs confidential speech privacy: meeting rooms, consulting suites, and teaching spaces separated from circulation.
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 |
|---|---|
| Single door | Rw 40 |
| Double door | Rw 40 |
Laboratory ratings for the complete tested system. Installed performance depends on the opening being built and sealed as tested.
This door is supplied with your choice of jamb. Confirm the jamb type with your order.
