Sound insulation for walls

At the present time, it has become important to ensure the isolation of newly constructed rooms and buildings. Insulation helps maintain the privacy of residents and prevents them from being affected by external noise resulting from population density in cities in particular. Population density is the reason for the large number of high-rise buildings that contain many apartments. In which many people live next to each other, it is therefore important to maintain the privacy of each house in general through insulation during the construction of the house. Insulation has many types and benefits, and the most important types are sound and heat insulation. The benefits of these two types of insulation are very many, including reducing Noise and reduced electrical consumption, as good insulation maintains the building’s internal temperature and reduces the use of air conditioning in the summer and heating equipment in the winter.

Sound insulation

Sound insulation means ensuring that sound does not transmit to and from the place to be isolated. When placing materials for sound insulation, it is important to understand many engineering terms through which the appropriate type of insulation is determined, such as knowing the speed of sound, sound frequency, sound intensity, and other factors that affect the type and quality of insulation. The type of insulating material used in movie halls is not the same as what is used in homes or companies. The insulation process is done by placing materials designated for the insulation process between the concrete while it is under construction. There are many insulating materials, each of which has ideal methods for implementing insulation in an ideal manner.

Materials used in sound insulation

Many specially manufactured structural materials are involved in sound insulation processes, such as:

Extruded polystyrene panels.
Boards made of cork.
Gypsum boards.
Light foam mortar (foam), which is in the form of a spray. After it is placed between the concrete, it reacts and forms a solid material filled with gaps.
Bituminous panels, which are made of burlap with tar or paper with tar.
Acoustic foam polyurethane foam is similar to light foam mortar in its working principle and differs in its properties.
Some developed cement materials that are used to create a layer of what is known as cement plaster.

Correct insulation methods

In order to ensure good insulation and prevent the penetration of sounds through the walls, care must be taken to implement all types of insulation process perfectly, and in particular, there are many steps that are recommended to be implemented when placing extruded polystyrene sheets in insulation.

Make sure to obtain insulating materials from places designated to sell them in an approved and guaranteed manner.
Care must be taken to cover all surfaces to be insulated with insulation materials in order to achieve the desired result of insulation.
It is important to be careful not to leave large spaces and gaps between the insulating panels.
After placing the insulating pieces, care must be taken to cover the joints between the pieces with the adhesive tape designated for that purpose.
It is important to cover the insulating material with some special films that protect the insulating material.

Forms of sound insulation in buildings

Sound insulation by preventing sound transmission through partitions, walls and external ceilings.
Sound insulation by preventing the transmission of vibrations and sounds generated by machines.
Sound insulation method by absorbing sound and noise generated from inside.
