Thermocol is a popular soundproofing material that is available in a wide variety of colors. It is also available in a sound transmission class of 0.3, which indicates that the material has a good sound reduction ability. This class helps you to determine how well Thermocol will soundproof a room, door, or window. Sound travels through thin walls and holes in windows and doors, and you should choose a soundproofing material that has a high transmission class to help minimize noise. Thermocol works well with other sound blocking materials, such as stone wool or EPS, to provide a total effect.

While the two types of foam are often used interchangeably, they have vastly different physical properties. One of the most important factors in soundproofing a room is mass and density. Thermocol has neither of these attributes. Instead, it is highly reflective and will cause echoes in the room. Besides, these materials are not very sustainable, and can take millions of years to decompose.

As a soundproofing material, polystyrene foams can effectively block outside noise from penetrating the room. However, polystyrene cannot completely block out sound, as some of it can penetrate its surface. The best way to use Styrofoam for soundproofing is to use it with denser materials to create a solid barrier between the sound and the room.


When constructing a room, one of the most important factors in soundproofing is material. While foams and curtains are great soundproofing materials, Thermocol has some drawbacks. While it does not absorb sound like a conventional wall or ceiling, it can reflect sound. This will help reduce noise within the room, but not completely prevent it from entering the space. Because of its reflective nature, thermocol will cause echoes to occur.

Thermocol has a low absorbing power, making it less effective than other materials. It’s best to use a more durable material that will last for several decades. It’s also easier to clean than some other materials, such as Thermocol. Nevertheless, it does not have any insulation properties. Thermocol can also be used to control reflections in a studio.

Stone wool

Thermal efficiency is a key feature of stone wool insulation. The material’s high thermal efficiency makes it an economical option for covering rooms. It can keep a room warmer in winter and cooler in summer. Its superior acoustic performance means it blocks out sound frequencies below 1kHz. Unlike thermocol, stone wool is not combustible, so it cannot promote flame spread. It also helps reduce vibration time, making it an excellent option for noise reduction in residential construction.

Polystyrene, a popular thermal insulator, lacks mass, which makes it ineffective for soundproofing. Despite this drawback, EPS still performs well in commercial construction. It muffles sound in walls by decoupling different layers of walls. It also has a low absorption coefficient. As a result, stone wool is a soundproof choice for homes and businesses.


EPS (Expanded Polystyrene) is a popular building material. Its lightweight, strong, and rigid structure make it an excellent choice for insulating a home. However, while EPS is a great thermal insulator, it lacks the mass necessary to absorb sound. While polystyrene is a good thermal insulator, it is not a good choice for absorbing sound at lower frequencies. EPS is generally considered soundproof when used in conjunction with other materials to improve its noise absorption and decoupling qualities.

The transmission of sound is largely dependent on the material in the path of the sound waves, and its construction method. However, EPS can significantly reduce the amount of noise transmitted through partitioned walls, ceilings, and floors. EPS applications are especially helpful in multi-family housing, as well as structures near airports. These benefits have made EPS an increasingly popular choice for soundproofing. However, many factors must be considered before deciding whether or not EPS is right for you.
