LINEAR ACOUSTIC CEILING SYSTEMS

Beam.
Structure overhead.

Beam is a suspended linear acoustic ceiling system with a porous PET face and an internal structural core. Available in Narrow and Wide profiles, it brings sound absorption, strong architectural lines and overhead depth to open-plan offices, reception spaces and collaboration areas.

LINEAR RHYTHM, ACOUSTIC DEPTH

More than
a ceiling line.

Beam combines a porous acoustic face with a hollow internal cavity. Sound enters through the PET surface and is absorbed within the assembly, bringing acoustic treatment into the ceiling’s architectural rhythm.

A concealed spine supports long, aligned runs. Suspension height, spacing, lighting and building services are coordinated as part of the layout.

A different presence.

Choose the proportion that suits the room, then coordinate the spacing, suspension and acoustic layout.

Beam Narrow linear ceiling profile visualisation

Beam Narrow

A slender rectilinear profile for a finer overhead rhythm. Suited to compact zones and spaces where the ceiling should feel visually lighter.

Beam Wide ceiling profile visualisation with a broader rectilinear expression

Beam Wide

A broader profile with greater internal cavity volume and a stronger architectural presence. Suited to larger collaboration areas, reception spaces and town-hall settings.

Acoustic figures relate to the configured assembly and air gap. The suspension layout is developed around the room, lighting and building services.

in practice.

The questions that help shape a ceiling brief.

What is an acoustic ceiling beam?

An acoustic ceiling beam is a linear overhead element that combines a three-dimensional profile with sound-absorbing material. ATR Beam uses a porous PET face and an internal cavity to bring acoustic treatment into an architectural ceiling layout.

What is the difference between Beam Narrow and Beam Wide?

Narrow creates a finer, visually lighter line. Wide has a broader profile and larger internal cavity, offering a stronger architectural presence and a different absorption spectrum. The choice should reflect the room’s scale, acoustic brief and available ceiling depth.

How is Beam installed?

Beam can use adjustable stainless-steel suspension cables or direct-fix mechanical tracks connected to its internal spine. The mounting arrangement and suspension height are coordinated with the project team.

Can Beam work around lighting and ceiling services?

Yes. Beam layouts are developed around lighting, ventilation, sprinkler locations and maintenance access. Share a reflected ceiling plan or services drawing so these interfaces can be coordinated from the outset.

What information does ATR need to develop a layout?

Start with the room dimensions, ceiling height, intended use and any drawings showing lighting or services. Include the sound issue you want to address and whether you prefer a visually lighter or more substantial ceiling expression.

Why does the specification include an NRC above 1.00?

For a suspended array, the specification derives its apparent absorption coefficient from the array’s absorption area divided by its projected ceiling footprint. This can produce an apparent value above 1.00; it is not a claim that a material absorbs more than 100% of incident energy.
