Acoustics at the Heart of What We Do

At Unifold, we consider it a privilege to work in such a specialised industry. Acoustic operable walls have been in service for decades — and so have we. Over this time, our team has taken great pride in not only delivering the highest-quality systems but also in driving the industry forward. That’s why we invest heavily in research, use only the best quality materials, and continue testing and refining our designs to make sure every wall we build performs exactly as it should.

Rw Explained

The performance of an operable wall is measured in a laboratory and expressed as its Weighted Sound Reduction Index (RW), in decibels (dB). RW is a composite rating of sound reduction across frequencies from 100Hz to 5000Hz, when compared to an Australian Standard reference curve.

You may also hear the term STC (Sound Transmission Class) — essentially the same measurement, with comparable numerical values.

Put simply: the higher the RW number, the greater the sound reduction.

Laboratory vs Real Life

It is important to understand that a laboratory result (Lab RW) is not always the same as what you’ll experience in real life. Even a perfectly installed operable wall cannot account for all the imperfections in a building. Sound can “leak” through air-conditioning ducts, ceilings, carpets, and tiles — all of which can reduce field performance by as much as 10–15%.

That’s why we recommend ensuring surrounding structures such as walls, floors, and ceilings are rated at least 6–10 dB higher than the operable wall itself. This ensures your investment in acoustics is protected and performs to its full potential.

Typical RW Ratings & Applications

Lab RW (dB)EffectTypical Use
30 – 35Basic sound reduction for environments with moderate noiseStaff offices
35 – 41Elevated sound reduction for places that requires more privacySmall meeting spaces, consultation rooms
41 – 45Normal voices barely intelligibleMeeting rooms, schools, multipurpose halls
45 – 47Normal voices unintelligibleBoardrooms, training rooms, small conference spaces
47 – 49Raised voices barely intelligibleHotel function rooms, lecture theatres
49 – 53Major function noise controlledLarge function rooms, convention centres
53 – 55Industry-leading performanceHigh-security meetings, premium conference facilities

Note: Real-life performance can be up to 10–15% lower than laboratory results due to building conditions such as ceilings, ductwork, or floor finishes.

 

What This Means for You

  • Choose a sound rating that is in balance with the surrounding structure.
  • Remember that real-world performance will always differ slightly from the lab.
  • Focus on controlling leakage points such as ceiling voids or ductwork.
  • Don’t get caught up in “numbers’ games” — a 1–2 dB variation is not noticeable to the human ear.
  • Always look for independent, reputable testing (beware of overseas or non-standard tests that may inflate results).
 

No Shortcuts, No Magic Material

We are often asked if there’s a secret to achieving high acoustic ratings. The truth? There’s no magic material. Mass is the key. Thicker, heavier panels deliver stronger sound reduction. Thin, lightweight options might look appealing but simply cannot perform at the same level. At Unifold, we design with honesty and integrity — using the right materials to achieve the right result, every time.

The slider includes four panel types:

Fixed Panel – Fixed to the structure support and floor.
Standard Panel – Normal moving panel. This panel is in between the fixed and door panels.
Active Door – The door for accessing the room.
Passive door – The door with drop and top bolts to fix in place when they want to close the slider wall or use only active door. These bolts can be released to create a larger opening or fully open the room.

There are 2 main configurations: one way and bi-part. One way has panels only coming from one side, either from the left or right. Bi-part has panels coming from both left and right.

Single
Bi-parting

The Sliders can also come in single, dual, and triple panels. These can be used in combination with one way and bi-part, depending on what is needed.

Dual
Triple

There are 3 fixing types: Cavity, Reveal, and Face Mount.

CAVITY - This fixing needs a wall pocket (by others). The panel can be hidden into the pocket when not in use.
REVEAL - When not in use, panels are kept into a fixed panel at either side (or both if bi-part) of the wall.
FACE MOUNT - This is used for sliders with a single door only.

All our sliding doors are custom-made to suit your specific requirements although as a standard finish, you can choose from our wide range of glass finishes.
