The short answer: the main soundproof door cost factors are the acoustic rating, size and number of leaves, core and seals, fire rating, vision panel, frame, hardware, finish and installation. An office door around STC 35 costs far less than a studio door above STC 50, so set the target first and price against it.
“Soundproof door price in Pakistan” is a common question from our clients. We do not publish a price list, because two doors that look identical can differ greatly in performance and cost. This guide explains what is behind the quote, so you can compare offers fairly and avoid paying for a door that does not perform.
Why does the door matter so much?
A wall is only as good as its weakest point, and the darwaza (door) is usually that point. A standard hollow door with a 10 mm or larger gap under the leaf typically rates around STC 20, while the wall beside it may be STC 45 or more. Upgrading the door is often the biggest single improvement in a meeting room, studio or office.
Cost factor 1: how does the STC rating change the cost?
| Typical door type | Typical rating range | Common use |
|---|---|---|
| Hollow core door, no seals, 10 mm or larger gap under the leaf | About STC 18 to 22 | Not suitable for privacy |
| Solid core door with basic seals | About STC 28 to 32 | Offices with modest needs |
| Acoustic door, single leaf, full seals and drop seal | About STC 35 to 45 | Meeting rooms, cabins, classrooms |
| High-performance acoustic door | About STC 45 to 55 | Studios, control rooms, plant rooms |
| Sound lock: two acoustic doors with a lobby | Combined performance well above a single door | Recording studios, broadcast and cinemas |
Indicative ranges from published laboratory tests; the BOQ lists tested data for the exact product or system. The rating applies to the complete door set (leaf, frame and seals) as tested, not just the leaf. Always ask for the test report or data sheet. For background on the scale itself, see this STC explainer. Higher ratings need heavier cores, more seals and tighter tolerances, which is the biggest driver of cost.
Cost factor 2: size and number of leaves
Larger doors weigh more, need stronger frames and hinges, and are harder to seal. Double doors for auditoriums and halls need seals where the two leaves meet, which adds cost and complexity. Non-standard heights and widths also increase cost because they are made to order.
Cost factor 3: core, construction and seals
- Core: dense layered cores, sometimes with damping layers, perform better than solid timber alone.
- Perimeter seals: compression or magnetic seals around the frame; some doors use double rows.
- Drop seal: an automatic seal at the bottom that drops when the door closes. It avoids a threshold that people trip over.
- Threshold: some high-rated doors use a raised or sealed threshold.
Cost factor 4: does a fire rating add to the cost?
Public buildings, corridors and plant rooms often need fire-rated doors as well. A door that is both fire rated and acoustic needs fire test evidence for the complete door set, and acoustic test data for the same leaf, frame and seals, with the right hardware and intumescent seals. Ask for the fire test certificate and make sure the acoustic seals are compatible with it. The same reports matter for wall linings; see fire rated acoustic panels and their test reports.
Cost factor 5: vision panels and glazing
A vision panel improves safety and visibility, especially in studios, classrooms and control rooms. It must use acoustic glazing, often laminated or double laminated, set in a sealed bead. Larger panels and fire-rated glass add cost.
Cost factor 6: can I keep my existing frame?
A soundproof door needs a rigid, well-sealed frame. Steel or heavy timber frames cost more but hold the seals in line. If the existing wall is uneven, damaged or too thin, the opening may need repair or packing. The gap between frame and wall must be filled and sealed with acoustic sealant.
Cost factor 7: hardware
Panic bars for public halls, door closers, lever handles, locks, access control, hinges rated for the weight, and kick plates all add to the cost. Heavy acoustic doors need heavy-duty hinges and closers.
Cost factor 8: finish
Laminate, veneer, paint or fabric finishes, matched to the interior, change the price. Premium veneers and custom colours cost more than standard laminates.
Cost factor 9: installation and site
Installation includes removing the old door, adjusting the opening, fixing the frame, setting the seals and testing the closing action. Working at height, after hours, in occupied government buildings or outside Lahore can affect the cost. Transport to Islamabad, Karachi or other cities is planned in the quote.
Getting a fair quote
- Set the target rating for each room before asking for prices.
- Prepare a door schedule listing each opening with size, rating, fire rating, glazing, hardware and finish.
- Ask for test data for the complete door set, not just a brochure claim.
- Compare like with like: one supplier’s “soundproof door” may be a solid door with a strip seal; another’s may be a tested acoustic door set.
- Check the wall: an excellent door in a weak wall will not give the result you expect.
Our door work
Sound Krafted supplies and installs acoustic single and double doors, sound lock lobbies, vision panels with acoustic glazing and fire-rated acoustic doors. See our range of soundproof doors in Pakistan, our meeting room soundproofing service, and our wider guide to soundproof room cost in Pakistan. Our project for the Punjab Education Foundation included soundproof doors as part of a turnkey auditorium with soundproofing and acoustic ceilings; our guide to auditorium soundproofing, acoustic treatment and doors covers hall doors in detail. For windows, read what shapes the cost of soundproof windows.

Frequently asked questions
Why do soundproof door prices vary so much?
Because rating, size, core, seals, fire rating, glazing, hardware and finish all change. A tested STC 50 studio door set is a very different product from a solid door with a strip seal.
Can you fit a soundproof door in my existing frame?
Usually we fit a new acoustic frame in the existing opening, because the old frame rarely holds the seals well. We check the wall during the survey.
Is a solid wooden door the same as a soundproof door?
No. A solid door is better than a hollow one, but without proper seals, a drop seal and a rigid frame, its performance stays limited.
Do I need a fire-rated acoustic door?
In many public buildings, corridors and plant rooms, yes. The building’s fire plan decides. The door must be tested for both fire and acoustics.
How long does installation take?
A single door set is often fitted in a day once the opening is ready. Larger orders are scheduled around building use.
