Convoluted foam

What is convoluted foam?

Convoluted foam is a high-quality foam with an open-cell polyether and a very good self-adhesive layer. The foam ensures that the reverberation in a room is reduced. Convoluted foam is known at EASY Noise Control under the name EASYfoam NP. Our acoustic foam has a high density. Because of this, the sound waves are absorbed well and the addition of this foam ensures good acoustics in the room.

The size of the cells in the convoluted foam is important. When these cells are too open, the sound is not absorbed. But when the cells are too closed, the sound is reflected. This is also taken into account with the EASYfoam, which is why the foam has a high density.

The products from the EASYfoam line are made of a very sturdy material, which can easily be pressed in without damage. Therefore, the foam can take a beating and has a long lifespan.

What types of profiled foam does EASY Noise Control have?

EASY Noise Control has two types of EASYfoam convoluted foam in its range. Namely the following types:

• EASYfoam NP Premium;
• EASYfoam NP Plus.

EASY Noise Control also has an EASYfoam pyramid foam in its range.

Below, we explain the advantages, thicknesses and dimensions of each type of EASYfoam. If you have any questions about one of the products or which type of foam is most suitable for your application, please feel free to contact us. The EASYfoam NP Premium is a high-quality open-cell polyether foam and has a luxurious appearance due to its fine convoluted structure. The EASYfoam NP Premium is available in thicknesses of 30 mm, 50 mm and 80 mm. The dimensions in which this foam is available are 100 x 60 cm and 120 x 100 cm.

EASYfoam pyramid foam has a sturdy pyramid structure and is lightweight, making the product easy to apply. The pyramid foam is available in a thickness of 50 mm and in a dimension of 95 x 60 cm. This foam has a very even cell distribution which looks nice and ensures that the material feels solid and is also sturdy. Pyramid foam is a profiled foam, just like convoluted foam, but the nubs do not have a round shape. As the name suggests, they have a pyramid shape.

The EASYfoam NP plus is made of a high-quality open-cell polyether foam and is very sturdy thanks to the even cell distribution. This variant is different because of its fine and pointed structure. EASYfoam NP plus is available in thicknesses of 30 mm and 50 mm and in the dimensions 100 x 60 cm and 120 x 100 cm.

All three types of EASYfoam can be ordered with a self-adhesive back. Due to this self-adhesive backing, the acoustic foam can easily be attached to walls and ceilings. This makes it easy to apply the convoluted foam (yourself). Make sure that the surface is clean, dust-free, grease-free and dry before applying.

Need a different shape of convoluted foam? That is no problem at all! The foam can easily be cut to size with a Stanley knife or band saw.

For which applications is convoluted foam used?

Convoluted foam can be used for many applications thanks to its sound-absorbing properties. For example, it can be used in sound studios, in technical areas, in air handling units, in cabin construction, in air ducts and/or in server rooms.

What are the advantages of convoluted foam?

A big advantage is that it is an affordable solution to improve acoustics. In addition, the foam is easy to customise, so it can be used in many different applications. The foam is sound absorbing and is excellent for sound insulation. Due to the open cell structure, it shortens the reverberation time in the room, which improves the acoustics.

EASYfoam is easy to install yourself, because of the possibility to order the product with a self-adhesive back. Would you rather have it installed? That is no problem with EASY Noise Control! We have fitters who are happy to come and install it for you. For more information, please contact one of our acoustic consultants.

Does having convoluted foam underneath the table help?

No, convoluted foam under the table does not help (enough). In a room where you want to improve the acoustics, it is important that sound waves are absorbed as quickly as possible. It takes too long for these sound waves to be absorbed under the table. These sound waves have already been reflected several times between the walls, the ceiling and the floor.

It is therefore smarter to place acoustic materials on the ceiling or against the walls. Sound is then absorbed as quickly as possible

Can convoluted foam be used in vehicles?

We often get the question of whether convoluted foam can be used for a car, a boat or a motor home. In principle, this could be done, but it is not the best solution. The nubs often get in the way there and convoluted foam does not have a moisture- and oil-resistant top layer. We have solutions especially for improving sound insulation in vehicles. So instead of convoluted foam for your vehicle, it is better to opt for EASYfoam polyurethane foam or EASYdemp anti-drumming plates.
