Pacific AD500 Acoustic Door Set STC/RW 50
The AD500 is a tested acoustic door set designed to reduce sound transmission within buildings.
The AD500 is a hinged flush panel door that is suitable for interior and sheltered exterior use. It is available as a single or pair door set.
The AD500 is a high-end acoustic doorset. In order to provide the very high acoustic rating it is much thicker and heavier than a regular door and has tight fitting acoustic seals. This means that it can be hard to open and close, especially if installed in a small air-tight room.
The AD500 is not suitable as a partition in high traffic areas or on access routes. People with disabilities may find it hard to operate.
The thickness of the AD500 door leaf is 68mm with an approximate leaf weight of 75kg/m2
|Wall Type||Bottom Seals||Acoustic Rating||Door Application||Max Leaf
|Suitable Acoustic Rated Wall||Threshold Plate + Drop Seal||50||Single||2400||1200|
|Double Drop Seal||48||Single||2400||1200|
- Please note that the maximum leaf width shown above is measured per door leaf.
The perimeter frame seals are self-adhesive seals mounted in the frame rebate, so are hidden when the door is closed.
There are two options for the bottom seals:
Threshold Plate + Drop Seal
Double Drop Seal
A steel threshold plate with a 20 mm step to hold one line of self-adhesive foam seal (identical to perimeter seals) is fitted to the floor. In addition to this there is one drop seal rebated into the bottom edge of the door. The height of the gap between the finished floor level and the bottom of the door must be set up carefully during installation of the door set so that the door will engage with the threshold seal as intended. For optimum performance the threshold plate should be sealed to the floor.
Two drop seals are fitted to the door leaf; one rebated into the bottom edge and one face mounted along the bottom of the blank face. The seals need to engage on a flat, hard surface e.g. a smooth concrete floor or a flat steel threshold plate as shown in drawing below. If a threshold plate is used it should be sealed to the floor.
The AD500 requires suitable latching in order for the frame seals to fully seal the gap between door leaf and frame. Mechanical latching hardware is essential for the performance of this door, push/pull hardware is not an option.
Practically any standard door hardware can be used on the AD500. Extended backset locks (70mm or more) should be used if at all possible. Proposed hardware must be advised to Pacific Door Systems Ltd to assess the suitability, before manufacture.
Due to the weight of this door we recommend using the ASSA ABLOY DC700 G-CM heavy duty closer.
Due to the high acoustic nature of this door set, a door closer will pull the door into the closed position, however the door may require additional manual force for latching and full acoustic performance.
If a power transfer device is fitted to the door, the door leaf will not be able to open past 110 degrees.
Concealed hinges are not an option on this doorset. The doorset is only available with a full height Pemko _FS_ Full Surface Aluminium Hinge.
Any penetrations through the leaf should be packed with acoustic materials (e.g. batts) wherever possible.
Recommended latching points are shown in the below diagram. Pair doorsets require a designated inactive leaf which is secured top and bottom.
The facings listed below are available for the AD500 door set
- Steel, either galvanised or electrogalvanised
- Decorative facings (timber veneer, formica etc) on MDF
- Other facings may be available, please contact Pacific Doors to discuss further options.
- The AD500 can be powder coated, but may have visible undulations in the door face.
All doors have a 1.2 mm steel capping folded around all edges of the door leaf.
Frame Types & Profiles
The timber frame profiles listed below are available for the AD500 door set
The steel frame profiles listed below are available for the AD500 door set
The frame is made from 2 mm folded EGZ or galvanised steel. The steel frames require packing of the frame during installation with fibrous insulation material (e.g. fibreglass, mineral wool or polyester batts).
For more in depth information on frame profiles, please see our Installation Instructions.
The meeting stiles listed below are applicable to pair door sets only.
The AD500 door set is suitable for installation in timber stud, steel stud and masonry walls of a suitable acoustic construction. If a lightweight wall construction is used, special design of the wall opening may be required to ensure it will support the weight of the AD500 doorset.
The standard installation method for plasterboard walls is by 12g screws at max. 450 mm centres.
The standard for Masonry installation is M8 Excalibur screwbolts (or similar) at max. 450 mm centres. No fasteners are exposed to weather or attack face.
Door sets must be installed carefully with particular attention to the sealing of gaps, including around the frame to wall junction.
AD-series acoustic doors are available with a smoke control rating (-/-/-/ SM) when hung in a timber frame. These doors comply with the NZBC C/AS2 C6.1.2 definition of smoke control doors.
The AD500 is not tested for weathertightness to AS/NZS 4284:2008.
The steel faced AD500 is made from exterior grade materials and would be suitable for use in protected exterior locations.
Product Optional Extras
|Glazing Type||Maximum Glazed Area||Max Height (mm)||Max Width (mm)||Glazing Bead||STC/Rw Rating|
- Please note that the height and width of the vision panel must still fall within the maximum glazed area.
- Maximum glazed area is measured per door leaf.
- Vision panel size and location is dependent on hardware selection.
Sidelights and Overlights
Timber framed AD-series acoustic doors can be combined with our SPA-series acoustic windows to form a doorset and sidelight combination. Door and window supplied in separate frames to be joined on site by the installer. Separate acoustic tags will be issued. Overall acoustic performance limited to that of the lowest rated unit.
There is no steel framed door / sidelight combination available.
Overpanels are not an option on this door set as it would impact the acoustic performance of the door set.
