Custom acoustic doors made to your opening — Rw 36 tested
Off-the-shelf “acoustic” doors are usually a solid-core door with a bit of extra mass and a sticker. Ours are custom-made to the exact size of your door opening, acoustic-tested to Rw 36, with Tecsound layered into the core. The difference is significant.

What makes a Quash door different
Most “acoustic doors” on the market are a contractor-grade solid-core door with seals added. They’re heavier than a hollow-core internal door, but the acoustic performance is modest and rarely tested.
Our doors are different in three specific ways:
1. Custom made to the exact size of your opening. We don’t supply a stock door and shave it to fit. The door is manufactured for your specific opening, which means the seals work properly across the full perimeter.
2. Tecsound layered into the core. A particle-board substrate sandwiches a Tecsound membrane. That gives the door three-way performance — disconnect, dampen, block — that a plain solid-core door can’t match.
3. Acoustic tested to Rw 36. Our manufacturer has had the doorset tested under standard acoustic test conditions. Rw 36 is a measured rating, not a marketing claim.
The finish on the face is either pre-coated for interior use, or weather-sealed for exterior — your call depending on where the door is going.
What you can realistically expect
Depends entirely on what door you’re replacing. The Rw 36 figure is the rating of our doorset on its own. The improvement you experience is the gap between what you have and what we install.
- Hollow-core internal door — typical Rw rating is around 15. Replace with a Quash door at Rw 36 and you’re looking at a significant lift. Practically, you’ll perceive at least a 10 dB reduction — internationally recognised as a halving of perceived sound.
- Glass or aluminium-framed door — better than a hollow-core door, but still not as good as our Rw 36 doors.
- Existing solid-core door with seals — smaller gap, but still a measurable improvement because of the Tecsound core and the testing-verified performance.
The real test isn’t the dB number on a meter. It’s whether you can hold a private consultation in your office, sleep through a noisy household, or stop hearing the toilet from the next room.

Hinges and existing frames — important to understand
This catches a lot of people out, so worth explaining properly. In Western Australia most homes with existing steel door frames are already bricked in. We work with that — we don’t rip the frame out unless we have to. There are two ways we fit our door into an existing steel frame:
Option 1 — cut off the original hinges and fit three new face-mounted hinges. This is our preferred method. Three hinges spread the load (our doors are significantly heavier than a hollow-core door) and the geometry of the seal works properly.
Option 2 — reuse the existing hinges to keep cost down. Our doors are heavy and existing hinges aren’t always rated for the weight, but where the frame is solid and the existing hinges are in good condition, we can fit to the existing two hinges.
One thing we can’t do: add an extra hinge to existing welded hinges. They’ve been welded behind the face of the frame, which consumes your door margin — a new hinge added in would pivot at a different centre and the door binds. So it’s either three new hinges, or reuse the existing ones — not a mix. Where the existing frame is flimsy, aluminium, or just not up to the acoustic job, we replace the frame entirely or add a moulding around it to create a new add-on frame.
Where Quash custom acoustic doors get installed
- Bedrooms — particularly in homes near roads, flight paths, or with noisy households
- Home theatres — keeping movie audio in, household noise out
- Studies and home offices — speech privacy and concentration
- Ensuites and bathrooms — toilet noise is one of the most-requested treatments
- Consulting rooms, medical and mental health practices — speech privacy is non-negotiable
- Offices, meeting rooms and board rooms — confidential conversations, executive offices
- Recording and rehearsal spaces
- Factory and industrial environments — workshop-to-office isolation, noisy plant areas
The top three questions we get asked
1. What does the door look like?
It looks like a plain, flush-panelled door — clean, paintable, designed to fit any interior or exterior aesthetic. The acoustic performance is in the core and the seals, not the face. We can also add moulding to give it more of a heritage look and character.
2. Do I have to buy new door handles?
No. We use your existing door furniture wherever possible — handles, locks, latches. We can fit new hardware if you want to change the look, but you don’t have to. If you do want a new look, generally you buy and we fit — keeps it simple as long as the mechanism is the same.
3. How much sound will it stop?
Depends on what you’ve got now. Our doorset is rated Rw 36; a typical hollow-core internal door is around Rw 15. Replacing one with the other gives you a significant uplift — well clear of a perceived halving of the sound. If your current door is glass or aluminium the uplift is still significant; if you’re already on a heavy solid-core with good seals it’s smaller but still measurable. We can also add barrier panels to existing doors, depending on usage and aesthetics.
When a Quash acoustic door isn’t the answer
We won’t sell you a door for the sake of it:
- The noise isn’t coming through the door — if the wall, ceiling or vents are leaking, replacing the door won’t fix the problem. We’ll find the actual leak first.
- Frame is unsuitable and can’t be upgraded — some openings need wall and frame work before a heavy acoustic door makes sense.
- Light-touch problems — if a properly sealed existing door would solve it, we’ll tell you that instead of selling you a new doorset.
Straight answers, every time.
FAQ
How much does it cost?
Depends on the size, the finish (interior/exterior), and whether we need to upgrade the frame. Once we have some details we can send you an online quote. A Quash custom doorset is significantly more than a hardware-store door — and significantly more cost-effective than continuing to live with the noise.
How long is the lead time?
Four to six weeks from order, because each door is custom manufactured for your specific opening. We book the install date during that window so the changeover happens efficiently.
Can you fit them as exterior doors?
Yes. We supply with an exterior weather-sealed finish — common for street-facing doors on busy roads, flight-path properties, and home offices opening to a courtyard.
Do you supply without installing?
We strongly recommend our install. Performance depends as much on the seal install and the threshold drop-down as on the door itself. Doors supplied without our install can underperform significantly.
Will the door be too heavy for normal use?
It’s heavier than a hollow-core door but designed to hang and swing normally on three properly-fitted hinges. People who live with them don’t comment on the weight — they comment on the silence.
Can I get one for a rental?
Possible, but it’s a permanent install and a custom door, so it’s an investment that stays with the property. Talk to your landlord first.
