PET-felt

Sustainable decoration
Acoustic felt is made of recycled polyethylene terephthalate (PET). A panel consists largely of recycled PET-bottles. Our printing technique ensures that the felt can still be recycled even with a complete print. 

Acoustic effect
The material is available in different thicknesses; the thicker the PET-felt, the higher the sound absorption. Thanks to our unique printing technique, the ink is not on top of the material, but enclosed in the felt fibre. In this way, the acoustic effect is preserved.

Safe for every room
PET-felt is fire retardant, because the material is hardly flammable and extinguishes flames. In addition, it is also resistant to mould and household dust mite. The material is maintenance-friendly, moisture retardant and therefore easy to clean.

Decorative addition
Acoustic felt has unprecedented processing options; printing, cutting, sawing and glueing. Iwaarden designs from all these possibilities. It results into a decorative eyecatcher for your room. Whether it concerns a wall covering, ceiling panel, partition wall or notice board. Our experienced designers see every opportunity to create a unique design in a combination of different shapes, as a 3D object, a pattern or a print.

Sublimation technique: to preserve the acoustic properties

We only use the sublimation technique to print on our PET-felt and consciously choose not to use UV-print and ink. Why? Because sublimation dyes are transferred under heat and pressure during the process. As a result, the print becomes part of the material and is enclosed in the PET-felt fibre. This provides an essential difference with UV-ink. UV-ink lies on top of the material and seals the material. As a result, the acoustic effect is lost. We therefore prefer sublimation printing. The material is respected, the felt structure remains visible, the acoustic properties are preserved and… it’s an eyecatcher. A sublimation print gives an aesthetically more beautiful result. The colours are brighter and deeper compared with UV-printing.


Here you can see the difference between sublimation technique and UV printing. The left photo shows a panel equipped with the sublimation technique. As a result, the material preserves its structure, keeping the acoustic properties intact. The right image shows a panel equipped with UV printing. The ink lies on top of the material, causing the fiber to lose its shape and seals the material. As a result, the acoustic properties are lost. 

Recycling possibilities
It is important to know that the PET-felt panels that have been printed by means of sublimation techniques don’t release harmful inks into the recycling process, as is the case with UV-ink. Sublimated PET-felt panels can simply be put in the PMD-bin at the end of their lifespan. This is in line with Iwaarden’s objective in terms of achieving the international ISO-standard 14001 (requirements for an environmental management system).

Unique designs with acoustic value
When designing a room, it often comes down to creating atmosphere, being innovative and having the right acoustics. The PET-felt offers all-in-one. We have all techniques for a suitable solution. Iwaarden designs, produces and assembles.

Endless colour range
We convert any PMS or RAL colour into a striking shade on PET-felt. We choose a basic shade from the range and process it until the right shade is achieved. This is possible with the sublimation technique, because the colour is sustainably integrated into the PET-felt fibre. A clear sign, that the material and its properties are preserved, even after sublimation.
