Keep takes cleaner
Reduce speech spill between the control room and recording booth. Start with 40–45 dB; consider 52 dB for a demanding studio.

Built for the way your room is used
One door family. Five sound insulation options.
Choose from nominal 30, 35, 40, 45 and 52 dB acoustic grades. Thicker door leaves support higher specified grades; the frame, perimeter seals, threshold and installation details matter just as much to the completed opening.

Select by noise source and privacy need
What does each rating feel like?
| Nominal option | Door leaf | Practical expectation* | Typical starting point |
|---|---|---|---|
| 30 dB | 70 mm | Helps soften ordinary voices and corridor activity; speech may remain understandable. | Internal offices, light-use rooms |
| 35 dB | 70 mm | Noticeably lowers conversational noise; loud speech may still be heard. | Meeting rooms, podcast rooms with modest noise |
| 40 dB | 90 mm | Improves speech privacy; raised voices can remain faint or indistinct. | Conference rooms, home cinemas, livestream rooms |
| 45 dB | 90 mm | Stronger isolation for speech and moderate program audio; loud bass still needs whole-room design. | Broadcast suites, recording rooms, entertainment rooms |
| 52 dB | 110 mm | High isolation target for demanding rooms; speech is typically hard to discern when the full enclosure is detailed well. | Professional studios, KTV, screening and performance spaces |
*These are general selection guides, not promised on-site reductions. The figures are nominal product options in dB; request the test report for the exact door assembly, size, glazing and hardware before specifying STC or a guaranteed result. Flanking paths through walls, ceilings, ducts and gaps can dominate on-site performance. Low-frequency bass is especially difficult to control.

Spaces that need sound control
Each image depicts the room itself. Choose the acoustic door configuration based on the actual noise source, adjoining spaces and project requirements.
TV / livestream
See the room, control the sound
A round or rectangular observation window supports visual coordination. Confirm its tested acoustic construction with the selected grade.
Home cinema
Contain film and music playback
40–45 dB is a useful discussion point for typical rooms. For elevated playback levels and bass, assess the wall and ventilation system too.
KTV / entertainment
Reduce room-to-room spill
Review 45–52 dB options and the complete sealing package for high-output venues and adjacent guest spaces.
Meeting / conference
Give conversations privacy
35–40 dB options suit many meeting areas; higher grades may be appropriate when confidential speech or noisy corridors are involved.

Finish and vision options
Solid colorClean single-color surfaces for offices, studios and modern interiors.
Wood grainA warmer visual character for hotels, meeting suites and home cinemas.
UpholsteredSoft padded panels for decorative studio and entertainment interiors.
Door face: flat, uninterrupted panel or integrated observation window. Window shape: round or rectangular. Other choices: single or double leaf, color, frame style, handing and hardware, subject to engineering review. A window, lock cutout or other change can affect the acoustic rating; approve the final assembly before manufacture.

Before ordering
What we need for an accurate proposal
- Send the finished wall opening width × height and wall thickness in millimetres; measure at several points.
- Confirm the swing direction with a plan view, hinge side and the side from which the door opens toward you.
- Tell us the room use, noise source and target grade; share any project acoustic report.
- Choose single/double leaf, flat panel or window, finish, frame, lock, closer and threshold.
- Confirm the drawing and tested assembly details before production; provide applicable fire or accessibility requirements if needed.
Acoustic treatment is a system: a good leaf alone cannot compensate for an unsealed threshold, weak surrounding wall or open ventilation path.

Projects with a separate fire requirement can also compare our custom steel fire door options. Specify acoustic and fire performance separately for the proposed assembly.
