Offices & collaborative spaces
Work. Talk. Focus.
Above desks or meeting tables, suspended lines structure the space. Rafts and baffles allow ceiling compositions tailored to the project.

01 / A different idea of comfort
Comfort you can see.
And hear.
A ceiling that sets the rhythm. Light that brings people together. A material that softens the atmosphere.
PET acoustic felt integrates into luminaires or takes the form of rafts, baffles and panels. It helps absorb some of the sound reflected within a room while opening up new possibilities for interior design.
01
Combine
Bring light and acoustic material together in one architectural gesture.
02
Compose
Use lines, circles and relief to give the space a sense of scale.
03
Coordinate
Connect felt colours to the palette and textures of your project.
Spaces for living
For every space,
its own harmony.
From workplaces to hospitality interiors, the same freedom to compose.
Hospitality, restaurants & lounges
Give reception spaces character.
Luminous circles, statement pendants and coloured felt create focal points above tables, counters and lounge seating.
Walls, circulation & living spaces
Make material your signature.
A continuous surface, a rhythm of panels or a graphic relief: felt becomes part of the interior design, alongside the light.
02 / Integrated lighting
A luminous presence.
An acoustic function.
Eight families, from suspended discs to architectural lines. Start with a silhouette, then refine the light.

PET felt
A soft material.
A bold design.
Made using recycled materials, PET felt brings texture and colour to a project. Flat, folded or sculpted into volume, it contributes to acoustic comfort, particularly at medium and high frequencies.
Material becomes a surface to shape, a suspended composition, a detail that brings a space to life.
03 / The architecture of material
Free the ceiling.
Dress the surfaces.
Fourteen ways to extend the architectural concept: sculpted modules, suspended rafts, baffles and decorative panels.
PET-12
Square module with opening
PET-13
Sculpted square module
PET-02
Multi-size suspended discs
PET-03
Square and rectangular rafts
PET-04
Linear baffles
PET-08
Large decorative panel
Illustrated compositions may combine several elements. Luminaires, supports and accessories are selected for each configuration.
04 / The project palette
Colour is
part of the design.
Mineral tones, botanical shades, deep accents. Felt fits your architectural language.
Choose a quiet shade to blend into the ceiling, or a bold colour to reveal a geometry. The ACO palette allows coordinated compositions; available colours vary by family.
Let’s discuss materials & finishes ↗Screen colours are indicative. Confirm against a sample for the project.
From concept to space
Compose together.
A selection that begins with your architectural intent.
Read the space
Volumes, ceiling height, glazing and activities: start with the architecture and the conversations within it.
Draw the composition
Choose a line, circle, raft or surface. Repeat, align and layer to find the right rhythm.
Coordinate the material
Pair the felt colour with the project materials, then tune the light to the desired atmosphere.
Refine the project
Share plans, dimensions and design intent with Lumisphere to refine references, options and layout.
A little further
A few pointers.
Acoustic lights or standalone panels?
Acoustic luminaires combine light with a PET acoustic element. Rafts, baffles and panels extend the composition independently of lighting points. Some modules are designed to work with luminaires; the combination is selected for each project.
Can colours be selected?
The collection offers an ACO felt palette. Available colours and thicknesses depend on the model. Final selection should be made using a material sample; screen colours are indicative.
How is the acoustic result assessed?
The result depends on room volume, existing materials, installed felt area and layout. Sizing needs to suit the room; choosing a luminaire alone does not establish a universal numerical improvement.
Which technical information supports specification?
The catalogue presents acoustic absorption testing to UNI EN ISO 354 and reaction-to-fire testing to EN 13823:2020 and EN ISO 11925-2:2020. For specification, request reports and classifications applicable to the selected product, material and installation. This page states no fire classification, NRC or αw value.
