Acoustic ceiling rafts and clouds.
PET felt ceiling rafts, also called acoustic clouds, that hang level below the ceiling, in five shapes and 12mm or 24mm. Every product page carries the full specs, test results, 3D model and hanging details, so you can buy with confidence.
Hanging wires included.Circle, square and hexagon rafts come with 2 pairs of 1m ceiling wires, rectangle and oval with 3 pairs, ready to hang level with nothing showing from below.
- Acoustics Up to Class A
- Fire safety Class B-s1,d0
- Colours Up to 48
- Sustainability 75% recycled
- Reliability 10-year guarantee
Class A is our calculation for 24mm hung on an air gap. 48 colours in 12mm, 20 in 24mm.
On every product page.
You shouldn't have to email to find out what a raft weighs or how it hangs. Open any raft and it is all there, written out in full.
3D model in every colour
Turn it, look up at it from below and switch colours before you buy. View it in your own room on your phone.
Try it on the hexagon →Weight for every size
Each size lists its hanging weight, so you can check your ceiling and fixings before you order.

Flat and with an air gap, each result labelled. The 400mm air gap is the lab mounting closest to a raft hung below a ceiling.

Pick a shape
Circle, square and hexagon from 600 to 1200mm. Rectangle and oval at 2400 x 1200 for one large statement.

12mm or 24mm
12mm is lighter, in 48 colours. 24mm has a deeper edge and tested air-gap results, in 20 colours.

How they hang
1m wires fix to flat plates on the top face: four on circle, square and hexagon, six on rectangle and oval. Wire length sets the drop, so nothing shows from below.

Choose your colour
48 colours in 12mm and 20 in 24mm. A sample pack shows the felt in your own light.
Ceiling raft questions.
What is an acoustic ceiling raft?
A flat felt panel that hangs level below the ceiling on wires. You see its full face from below, so it brings colour and shape overhead, and the felt softens sound in the space beneath. Our rafts are PET felt, made from 75% post-consumer recycled PET and fire rated Class B-s1,d0 to BS EN 13501-1:2018.
Are acoustic rafts the same as acoustic clouds?
Yes. Raft, cloud and ceiling cloud all describe the same thing: a flat felt panel hung level below the ceiling with open space around it. There is no fixed technical difference between them.
How do I reduce echo in a room?
Add soft surfaces that absorb sound instead of reflecting it. Echo builds up when sound bounces between hard surfaces like plaster, glass and hard floors. Rugs, curtains, soft furniture and acoustic panels all help. A ceiling raft adds absorption overhead, where there is often the most bare surface, and takes the edge off echo in the room below. Rafts reduce echo but don't soundproof, so they won't stop sound passing through walls or floors.
Raft or baffle?
A raft hangs flat, so you see its face from below. A ceiling baffle hangs on edge, so you see a line, and suits long runs and high ceilings. Grid baffles are blades that lock together into one sculpted piece. Rafts suit a single zone such as a meeting table, a reception desk or a dining area. See our ceiling baffles and grid baffles, or read the three types of acoustic ceiling.
Which shapes and sizes are there?
Circle, square and hexagon come in 600, 800, 1000 and 1200mm, in 12mm or 24mm. Circle sizes are the diameter and hexagon sizes are measured point to point. Rectangle and oval come in 2400 x 1200, in 24mm only. Square and rectangle rafts have 25mm radius corners.
How are ceiling rafts hung?
Circle, square and hexagon rafts come with 2 pairs of 1m ceiling wires, rectangle and oval with 3 pairs. Each wire fixes to a flat plate screwed into the top face of the raft, so nothing shows from the floor, and the raft hangs level. Wire length sets the drop. Extra pairs of ceiling raft wires are available separately.
How heavy are they?
Each product page lists the weight of every size. As a guide, a 1200 x 1200 square is about 3.5kg in 12mm and about 7.0kg in 24mm, and the 2400 x 1200 oval is about 11.0kg.
Do ceiling rafts absorb sound?
Yes, they soften echo in the room below. 24mm board tested with a 400mm air gap, the lab mounting closest to a hung raft, gives NRC 0.90, which is Class A by our calculation. Flat with no air gap, 24mm is Class D (αw 0.50) and 12mm is Class D (αw 0.30). A raft also absorbs on its back face and edges, so these per square metre figures are a conservative guide.
Where do your figures come from?
From independent laboratory tests to the standards we name: BS EN 13501-1 for fire, and EN ISO 354 and ASTM C423 for sound absorption. Every figure on our product pages and data sheets comes from those results, with the mounting stated.
How long does delivery take?
Every raft is made to order and dispatched in approx. 10 working days. Delivery is free to UK mainland addresses on orders over £50. The felt carries a 10-year guarantee and the wires 2 years.
