01 / Inside the engineering
Acoustic door construction:
core, frame and seals.
A high acoustic rating depends on the leaf, frame, seals and threshold working together. Explore the construction that makes the 50T a specialist doorset.
Illustrates the construction principle. Request the approved project detail for dimensions, fixings, hardware and seal positions.
01 Multi-layer acoustic core
A tri-layer core combines timber and acoustic insulation materials within solid perimeter rails. The outer skin completes the leaf and provides the foundation for your chosen finish.
An engineered build-up, from the centre to the surface.
02 Double rebates. Twin seals.
Double rebates at the head and jambs create two sealing lines around the top and sides of the leaf. Consistent seal contact is part of the acoustic design and needs to be maintained in service.
The perimeter deserves the same attention as the core.
03 A coordinated frame and hardware
Frame material, hinge selection, fixings and the surrounding wall all need coordination. Timber and metal frame options allow the opening to be developed around the interior and project requirements.
Confirm compatibility across the complete assembly.
04 Control at the threshold
A mechanical drop seal addresses the gap beneath the leaf when the door closes. Floor finish, threshold level and final adjustment are essential details to coordinate before installation.
Small gaps can compromise an otherwise well-specified opening.
You are specifying a complete acoustic assembly: a substantial leaf, controlled sealing lines, compatible hardware and a coordinated installation detail.
02 / Experience the upgrade
Compare acoustic
door performance.
Choose an example source level, then switch between No door and a closed 50 dB doorset. Explore the range or compare 55 dB with 60 dB. The demo applies the full selected reduction, with no listening boost.
For the same source, an additional 10 dB of uniform sound reduction corresponds to 90% less transmitted sound energy. This is an illustration, not a prediction of installed performance. Enable JavaScript to hear the comparison.
Rw is a weighted sound insulation rating. It is not the noise level of a room, and it does not mean equal reduction at every frequency. For bass-heavy music or demanding room criteria, ask for the frequency-band test data and an assessment of the complete room.
03 / Technical specification

Early design check
Plan for the weight.
Enter one leaf’s dimensions to estimate its mass using the published 60 kg/m² figure.
0.90 m × 2.10 m × 60 kg/m²
900 × 2,100 mm is an example and is not added to your brief. This is a mass estimate, not a size or hinge approval. It excludes any adjustment for glazing, ironmongery and other configuration changes. Confirm the final leaf mass and handling plan.

Choose the acoustic, fire and glazing requirements together. The following entries reflect the published 50T selection guide and require confirmation against the evidence for your proposed doorset.
| Configuration | Leaf arrangement | Fire requirement | Specification note |
|---|---|---|---|
| 50T / NFR | Single or double | Non-fire-rated | Coordinate the acoustic assembly, dimensions and hardware. |
| 50T / EI30 | Single or double | 30 minutes | Request the applicable classification and approved configuration. |
| 50T / EI60 | Single or double | 60 minutes | Confirm the permitted leaf size, glazing and hardware together. |
| 90-minute requirement | Single-leaf entry in the published guide | Technical confirmation required | Contact SilentDoor before specifying; do not assume availability for your assembly. |
The guide is not a test certificate. Maximum overall size, vision-panel area and fire performance must not be combined as independent allowances. Smoke-control performance requires separate confirmation.
Acoustic test evidence: what to request
Rw and frequency-band results
Rw is a weighted single-number rating. Ask for the sound reduction index, R, by frequency as well as the headline rating, especially where amplified music or low-frequency noise drives the brief.
Measurement and rating methods
ISO 10140-2 describes laboratory airborne sound-insulation measurement; ISO 717-1 describes its rating. Ask which standards and editions the supplied report uses, and check the tested specimen and installation.
The assembly behind the result
Confirm leaf arrangement, dimensions, frame, seals, threshold, glazing and ironmongery against the test evidence. A different combination needs review; the model name alone does not establish the approved scope.
These standards explain how to read acoustic evidence; their inclusion here is not a declaration that every 50T configuration has been tested to each named standard.
Frames, ironmongery and installation coordination
Structural opening and clear access
Record the structural opening, finished floor level, wall construction and required clear opening separately. Confirm handing, swing direction, frame profile and fixing detail on the project drawing.
Leaf mass and door operation
Coordinate hinges, closer, latch and any access-control hardware with the final leaf mass. Check closing action, seal engagement and the required opening effort as part of the complete hardware specification.
Sealing and the surrounding room
Coordinate the frame-to-wall junction and a suitable threshold surface for the drop seal. Review flanking paths through adjoining construction and services; sound can bypass the doorset.
04 / Material expression
Timber veneers and
doorset finishes.
Make the doorset part of the interior. Explore timber veneer references, request a painted or laminate finish, or send us a sample to discuss a coordinated match.
Explore a finish
Natural character. Carefully coordinated.
A lighter timber reference for interiors that bring grain and material warmth into focus. Confirm the veneer, cut and finish with a physical sample.
Screen images are indicative. Natural veneers vary in colour and grain. Availability, matching and suitability for your doorset require confirmation.

Acoustic doors for
studios and performance spaces.
The 50T can be considered for recording studios, rehearsal rooms and concert-hall openings. Select the rating from the source, the receiving-room criteria and the complete room design.
Recording & production
Consider the sound spectrum, monitoring levels and target background noise. Ask for band-by-band performance where low-frequency control is critical.
Rehearsal & performance
Coordinate audience circulation, equipment access, leaf size, closing hardware and seals alongside the acoustic brief.
Acoustically sensitive interiors
Review the wall, ceiling, floor and service penetrations. Sound can travel around an opening as well as through it.

Will an Rw 50 dB doorset make my room silent?
No doorset can guarantee silence in every room. Rw describes weighted sound insulation under laboratory conditions. The source spectrum, background noise, surrounding construction and installation all influence what you hear on site.
Why can a few extra decibels cost more?
Decibels use a logarithmic scale. A uniform 5 dB improvement leaves about 32% of the previously transmitted sound energy; a 10 dB improvement leaves 10%. Achieving higher doorset performance can call for different construction, greater mass, more demanding sealing and compatible hardware. Compare the complete specification and test evidence.
Can I combine acoustic performance, fire resistance and glazing?
These requirements must be checked as a combination. A rating or maximum size for one build-up should not be assumed to apply to another. Send your fire requirement, arrangement and proposed vision panel size so the corresponding assembly and evidence can be reviewed.
How should I choose between 50T, 55T and 60T?
Start with the acoustic criteria for the receiving room and the character of the noise source. Review frequency-band performance and the surrounding construction, then coordinate size, fire rating, glazing, mass and hardware. The listening tool explains relative changes; it is not a substitute for a project acoustic assessment.
What matters during installation and maintenance?
Follow the approved installation instructions for the frame, fixings, perimeter gap treatment, seals and threshold. Check that the leaf closes correctly and that seals engage as intended. Ongoing alignment and seal condition matter to the performance of a working door.
Are acoustic doors and acoustic wall panels doing the same job?
An acoustic doorset helps limit airborne sound passing through an opening. Absorptive wall and ceiling finishes address reflections and reverberation inside a room. A studio may need both, with the door, walls, floor, ceiling and ventilation considered together.
Does an acoustic rating also establish fire or smoke performance?
No. Acoustic, fire-resistance and smoke-control performance are different requirements. EN 1634-1 concerns fire-resistance testing of door assemblies; EN 1634-3 concerns smoke-control testing. Request the relevant evidence and classification for the actual doorset rather than inferring one performance from another.
What should I send for a quotation?
Send the door schedule, opening sizes, quantity, acoustic and fire requirements, handing, vision panel needs, finishes and ironmongery preferences. Include the site location, project drawings and programme where available.
