Description

ISOLfon – SEP is produced in sheets from high-quality, flexible polyurethane foam with a corrugated design (egg crate). It addresses acoustic improvement and noise control issues in structural constructions and industry in a simple and quick manner. To achieve a high sound absorption coefficient, the produced foam has the optimal percentage of closed cells, which absorb the kinetic energy caused by sound waves in the air. It is applied very easily and quickly without requiring special tools or specialized technical knowledge.

I bought the product (30mm) to organize the sound in my room. The foam panels worked relatively well. If you have a low budget and want an acoustic arrangement, you can use this product. I have purchased many of these products. I also used it for decorative purposes.

These products only provide acoustic treatment, they do not provide soundproofing. Acoustic treatment and soundproofing are two different things. If you are thinking of buying this product for soundproofing, you may be disappointed. Whatever you put in front of a wall will only provide minimal noise reduction. However, this does not mean that this product provides soundproofing. If you want real soundproofing, consult companies that specialize in soundproofing.

The pieces (although they seemed to be factory-cut) were cut crookedly.

And as for the pattern (it wasn't "straight" within the piece), and as for the angle (it wasn't completely rectangular) and as for the depth of the material!

As a result, putting 4 pieces to cover a door visually results in a mess. The seams don't align (since they are not of equal height) and the pattern doesn't follow the same angle from piece to piece. If you don't care at all about the visual aspect and the surface you want to cover is easy (without many angles, cuts, etc.) then it's OK.

Acoustically speaking, I think the result is satisfactory, without having much experience with similar materials.

    This review is about the thickness: 50 mm

    If you want to soundproof rooms from each other, this alone is not enough. It needs to be combined either with mineral wool or another type of soundproofing material, so add another 5-8 euros to its already excessively high price.

    I have been using this particular soundproofing material for about 1.5 years and I have to say that I am quite satisfied with its performance. I haven't used it in a studio or to insulate a room or anything like that, but I use it inside my speakers. Before a recent upgrade I made, I used these specific insulation materials inside the wooden cabinet and I have to say that it really 'sweetened' the sound a lot and tamed frequencies that were undesirable.

    This review is about the thickness: 50 mm

    It was purchased to limit the "echo" in an empty room.
    The difference before and after was small. I expected greater absorption, especially in the mid and low frequencies.

    This review is about the thickness: 25 mm

    I put them around a computer that has many NAS and Enterprise hard drives which sound like tractors especially when they write. It helped a lot with the noise. When it's quiet, I can still hear them but it's much better compared to before.

    I bought it to use it as a microphone stand to provide basic sound insulation.

    It does it quite well as the rest of the room has echo which doesn't pass through to the microphone.

    The thickness is not very thick, but I don't know if this affects the insulation much if it is for a whole room.
