Acoustic Doors

Acoustic door sets provide sound attenuation between rooms and spaces by incorporating a sound-rated acoustic door, frame hardware and acoustic seals. The three components – door leaf, frame, and seals together deliver an effective acoustic door.

Whether for school music rooms, concert halls, commercial sound studios, or privacy rooms, the Spence Doors range prevents noise interference while enhancing acoustics. Spence Doors has a range of hinged acoustic doors with listed performance from Rw 30 up to Rw 48. Our acoustic door systems use layers of insulating material to effectively reduce noise transmission between rooms.

With independent sound measurement test reports from the CSIRO/Acoustic Engineering Laboratories, our Acoustic Door Systems meet Australian Standard AS1191:2002 & ISO 140.3:1195 for acoustic performance. You can be confident of increased productivity, whether for industrial or residential use, with the acoustic range from Spence Doors.

The Door Leaf

An acoustic door leaf must feature a Solid Core. Whether Particleboard, Blockboard or Laminated Veneer Lumber (LVL), these cores are all solid throughout. In turn, they are able to provide the density required to resist the free passage of sound from one side of the door set to the other.

The Frame

An Acoustic Door Set may feature a frame of metal or timber composition as manufactured by Spence Doors. The fitting of an Acoustic Seal around a door’s perimeter requires the specification of an Acoustic Door Frame. That is a frame profile that features a return/rebate for the acoustic seal to sit inside. Pressed Metal Frames must also be backfilled during installation with mortar or another certified product. The subsequent solidity throughout the frame offers acoustic resistance against the passage of sound. Filling is not required for Timber Frames as they are naturally solid throughout.

The Seals

Designed to mitigate the passage of air through the gaps in a door set. A typical door set features a 3mm gap along its perimeter (sides and header) and a 3-10mm gap below the door, each of which present an opportunity for sound to pass through. This perimeter is addressed by an acoustic seal fitted into the frame to close off the gap and subsequent ability for sound to pass through. Similarly, the bottom-of-door gap is sealed by a Drop Seal / Bottom Seal which covers the gap between the door’s underside and the floor covering. This Bottom Seal may be surface mounted onto the door’s face or even recessed into the door’s underside to stay hidden in applications where aesthetic finish is important. Spence Doors’ Profiling service can prepare the cutout for the Bottom Seal to be made in advance and minimise the time and labour required when installing on-site. In a Pair Door application, acoustic seals are also required along each of the door’s leading edges. This comes as a result of the gap between doors presenting a new opportunity for sound to pass through. Meeting Stiles are fitted on these edges to seal off the gap and acoustically protect the opening.
