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

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.

Lab RW (dB)EffectTypical Use
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

 

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.

FIXED TOP & BOTTOM

The most economical solution for sealing off between the panels and the floor/track. Seals can accommodate 12mm variance in floor levels due to ‘tear-offs’ in each finger.

FIXED TOP & RETRACTABLE BOTTOM

Fixed top and retractable bottom seals: mainly used when floor levels exceed 20mm (up to 25mm), but also used on very high applications, where ease of operation is most critical. Seals can be activated manually or automatically.

RETRACTABLE TOP & BOTTOM

Retractable top and bottom seals: only recommended when the track and ceiling are perfectly flush for specific design. Seals can be activated manually or automatically.

FIXED TOP & BOTTOM

The most economical solution for sealing off between the panels and the floor/track. Seals can accommodate 12mm variance in floor levels due to ‘tear-offs’ in each finger.

FULL HEIGHT PASS DOOR

A full-height pass door is used to acoustically close the DG100 Operable Wall. This type of closure allows for a seamless full-glass effect while still providing access at one or both ends of the wall when it is closed.

EXPANDING JAMB

An expanding panel with a bulb seal is an alternative solution when no pass door is required and is the preferred option if the panels stack inside a cupboard. As glass panels cannot support an expanding panel, one end panel would need to be solid to accommodate this, this also opens up additional design opportunities, such as incorporating pinboard or whiteboard finishes on the solid panels.
