Hello everyone,
I have been thinking for a while about whether and how the well-known IKEA Billy shelves can be made soundproof. Specifically, I use the shelf as a room divider in a household with multiple people, but the noise from the other side is often disturbing. Since Billy shelves are made with thin particleboard and have open backs by default, I am wondering if there are practical and effective ways to improve their sound insulation.
Has anyone had experience with modifications or materials that can be added to significantly increase the soundproofing of Billy shelves? I am interested in both construction-related measures (e.g., linings, seals) and technical solutions (e.g., soundproofing pads, sealing). Thank you in advance!

Hello onju37,
Your question about whether it is possible to make BILLY shelves more soundproof can be answered from my experience and some technical knowledge.
First of all: The standard BILLY shelf is made of thin panels and is open at the back, which allows sound to pass through very easily. Acoustically, the shelf acts more like a lightweight partition that provides little insulation. To improve this, I recommend the following steps:
1. Replace or remove the back panel: The standard back panel is very thin and not soundproof. You can use a thicker MDF or OSB panel here, preferably at least 6 mm (1/4 inch) thick. The panel should be securely fixed to the side rails to avoid sound bridges.
2. Use sound insulation material: Behind the back panel, you can attach acoustic foam or mineral wool insulation mats (e.g., stone wool). These materials absorb sound, especially mid-range frequencies.
3. Apply seals: Sound can often enter through gaps. Use foam rubber or sealing foam strips on the edges, especially between the shelf and the floor as well as at joints.
4. On the front side, you might consider adding a plexiglass or glass panel as an additional barrier if the shelf is open. Glass increases mass and noticeably improves sound insulation.
5. The shelf can also be lined with carpet or felt to reduce sound reflections.
In summary: More mass, sound insulation materials, and sealed edges are key. Keep in mind that upgrading the shelf will make it significantly heavier and less mobile, and the effort involved varies depending on your requirements.
I hope my answer helps you!

are there practical and effective measures to improve the soundproofing of the BILLY shelves?Make the panels thicker, add seals to the joints, put insulation material inside. Done.
In addition to the options already mentioned, it should be noted that the biggest weak point of BILLY shelves is the back panel. By default, it consists of very thin hardboard, which has little sound-absorbing effect and allows sound to pass through almost unchanged.
If you want to improve stability and sound insulation, I would recommend using a combination of a thick, solid panel (e.g., MDF, 10 mm (0.4 inches) or thicker) and a layer of acoustically effective insulation materials behind it. It is important to attach the back panel as tightly as possible.
Additionally, sealing the edges and joints is necessary, as sound often leaks there. Besides foam rubber seals, avoiding gaps by careful alignment and, if necessary, gluing the panels together is recommended.
For optimal soundproofing, the interior can be filled with fibrous material such as mineral wool, although this will make the shelf heavier and less flexible.
I advise having realistic expectations: the shelf will never be completely soundproof, but the described measures will significantly reduce sound transmission.

More mass, sound insulation materials, and sealed edges are the key.That is correct. From a technical perspective, I would like to explain the principle of sound insulation: sound transmission through a construction element is reduced by mass, airtightness, and decoupling.
This means for the BILLY shelf:
- The thin particleboard of the back panel provides too little mass, resulting in sound transmission. Therefore, a solid, heavier panel would be more effective.
- Gaps or joints at the edges cause airborne sound leaks that allow sound waves to pass through. Sealing and caulking improve airtightness here.
- An absorptive layer can be added between the shelves and the back panel to absorb sound energy. Mineral wool or acoustic foam are suitable options.
- Decoupling the outer panels with intermediate layers prevents sound bridges.
Combining all these measures is necessary for the shelf to be effective as a sound insulation solution. However, the shelf alone does not replace a proper soundproof wall; it only provides local improvement.
Note: Impedance matching and resonance effects should be considered to avoid unwanted sound alterations.
If you want more details, I can also recommend specific products.

Make the panels thicker, seal the joints, add insulation.That sums it up pretty well, just a bit more detailed 🙂
I once tried using a BILLY shelf as a separating soundproof wall in my shared apartment room. I fitted an 8 mm (0.3 inch) MDF board on the back, sealed the edges with sealing tape, and placed mineral wool insulation behind the panel. The result wasn’t perfect, but definitely better – noises from loud TV were noticeably dampened.
Of course, BILLY is not a sound insulation miracle and you shouldn’t expect it to replace a concrete wall. But with a bit of effort and some affordable materials, you can achieve quite a bit 🙂
Good luck with your DIY project!
