Four black foam corner panels, each 48 cm long with a 12 × 12 cm section, for fitting in the corners where two walls meet. Each piece has a triangular section with grooves on the visible side. The pack contains only the 4 pieces: the supplier does not list an adhesive as included, so you will need to arrange fixing separately, with double-sided tape or spray glue. The foam may arrive compressed, so it is best to let it rest before fitting.

Foam acoustic corner panel: size and material

The pack contains 4 identical pieces, all black. Each piece measures 12 × 12 cm in section and 48 cm in length. The dimensions photo shows one piece only, so the values apply to each panel and not to the whole pack. Laid in a row, the 4 pieces cover 1.92 m of corner. The material is a soft foam, which the supplier describes as sponge. The listing gives a tolerance of 1-5 mm on the dimensions. The supplier does not state the weight.

How to assemble acoustic corner panels

The listing does not include an adhesive. The supplier's instructions call for applying double-sided tape or spray glue to the back and pressing the piece against a smooth wall. In the photo the panel stands upright, and the triangular profile and grooves are visible. Before fitting, clean and dry the wall and check that the piece sits flush against both walls of the corner: if the corner is not straight, gaps will be left. If the pack arrives compressed, open it and let the pieces rest in a ventilated place for one to two days, until they regain their shape. An honest tip: a strong adhesive can take some paint with it when peeled off.

One colour, several ways to arrange them

The corner panels are only available in black, in a pack of 4 pieces. The grooves on the visible side form parallel lines. The four pieces can be placed in a row along one corner, up to 1.92 m in total, or spread across different corners of the room. The photos show the pieces on their own, in pairs and all four together. The colour on screen may look slightly different from the real one.

Where to use acoustic corner panels

They are fitted in the corners where two walls of a room meet, for example in a bedroom, a living room or a home office. In a room with hard surfaces, sound bounces around and creates echo: the foam absorbs some of it. An important point: absorbing sound is not the same as stopping noise. Corner panels reduce echo inside the room, but they do not stop noise coming from outside, such as from neighbours or the street. The supplier gives no verifiable acoustic values, so we do not state any.

Frequently asked questions

Do the dimensions apply to each piece?

Yes. The supplier gives 12 × 12 × 48 cm, and the dimensions photo shows one piece only. The pack contains 4 pieces, so laid in a row they cover 1.92 m in length. The supplier allows a tolerance of 1-5 mm, so the pieces may differ slightly from one another.

Is double-sided tape included?

The supplier does not list it in the contents: the pack holds the 4 corner panels. The supplier's instructions call for double-sided tape or spray glue on the back. Choose an adhesive suitable for foam and for your wall, and test it first on a hidden spot, because a strong adhesive can take some paint with it.

Do they stop noise from outside?

No. They are acoustic corner panels: they reduce echo inside the room, but they do not stop noise from outside, such as from neighbours or the street. Stopping noise through a wall requires other materials and building work. The supplier gives no verifiable acoustic values, so we do not promise specific results.

Why do they arrive flattened?

The foam may arrive compressed in a sealed pack. The supplier advises opening it and letting the pieces rest in a ventilated place for one to two days before fitting, until they regain their shape. Do not fit them straight away: wait until they have regained their shape before applying the adhesive.

When will my order arrive?

Delivery takes 7 to 15 business days after payment; you receive the tracking number by email. The maximum delivery time is 15 business days: if it is not met, you can cancel the order and get a full refund.

Can I return the product?

Yes: you have 30 days from delivery to return the unused product in its original packaging. Return shipping costs are paid by the customer. All the details are in the return policy.
