Various noises such as car horns, conversations of people outside the building and the sound of chaos and traffic enter the building through doors, windows and walls and disturb the residents. these sounds always exist and you can 't prevent it . But there are many ways to avoid them .
In recent constructions, due to the increase in the volume of noise pollution, builders and contractors try to use materials that prevent noise from entering the building as much as possible. These materials have prevented a significant amount of voice transmission And provide a safe and quiet place for the welfare of residents.
Sound insulation is one of the essential needs in today's chaotic world in fact , it can be regarded as a barrier to reflection and transmission of sound .
today , many residential and residential buildings are equipped with these insulation . And the necessary standards have been observed to prevent noise in their construction.
Using sound insulation to insulate the walls of buildings not only creates a quiet environment in the face of crowded streets and noisy neighbors. it 's also a very professional practice to insulating the studios and the recording rooms . these walls of the wall are also resistant to noise in space and against the sounds resulting from mechanical blows such as rubber . One of the materials used in this type of system is rock wool, which is currently one of the best sound insulation.
to make your ceiling very well insulated , you must use a reflector that has high density And increase the weight of the roof. A sound insulation suitable for the roof is an insulation that improves the sound energy and vibrations in the roof of the house And prevents the transmission of sound in this way.
Rock wool is a sound, heat and fire insulation that is produced from a type of igneous rock called basalt, which is a remnant of volcanic activity. rock wool is non - insulating materials and its electrical conductivity is zero . This insulation is anti - allergic and has no harm to humans . the weight of this insulation is also light and does not overload the building . no chemicals used in producing rock wool . durability and longevity of this insulation are high and chemicals do not affect it . This element is considered as one of the best acoustic and sound insulators due to the mentioned features.
Polyurethane foam is a type of sound and heat insulation that has now become a widely used insulation in the construction industry. this chemical is composed of combination of isocyanate and polyester that both are liquid . Polyurethane foam spray is a suitable acoustic insulation that prevents the transmission of noise into the building.
another type of sound insulation is a elastomeric insulation . It has good resistance against pollution, moisture, water vapor and noise. elastomeric isolators have very light weight And due to their high flexibility, they are used for insulation of all types of construction installations, air ducts, large pipes, heating and cooling systems, and the automotive industry.
Laminated or cubic ionolites have a high density and are used as insulation in noisy places such as engine rooms. Basically, this type of insulation is installed during the hardening stage of the building and they absorb the sound well . They are made of polystyrene and provide a quiet atmosphere for residents. this insulation is applicable to both the ceiling and the wall and low cost options to prevent sound transmission. The price of roof ionolite is cheaper compared to other insulations, Therefore, it is widely used in recent constructions. Ionolite roof can be easily used because it is light weight and easy to transport. Polystyrene has a small and separate cellular structure Thus , it attracts a significant amount of noise and noise . It can be said that the amount of sound absorption is the same as wood and plaster. Its light weight lifts the building 's resistance to an earthquake And strengthens its safety. The higher their density, the more they absorb sound, even 100%. . Finally, it can be said that the use of polystyrene ionolite blocks minimizes the consumption of other materials.
This type of foam is made by putting together and gluing pieces of polyurethane foam and as an insulating sound insulation in the manufacturing industry. The steps of producing rebound foam are as follows :
1.Collection and classification of polyurethane foam waste
2.Crush the waste and mix it with glue
3.Condensate the mixture
4.Bake mixed with glue
5.cutting foam to the required dimensions
Oval comb foams are a type of sponge foam that is often used to insulate roofs, walls and back doors of studios, industrial plants, cinemas, amphitheaters and sound recording locations. These foams can absorb a wide range of high frequency sound and prevent it from returning. The apparent facade of these objects is in a way that increases their performance against the uptake of sound. easy installation , light weight , suitable price , ideal beauty , high performance and sound absorbing are among the obvious features of this product Which has made it a convenient and cost-effective option for consumers. the six - sided structure of this insulation increases its efficiency and leads to sound reduction Also, its cellular structure is closed. Therefore, in addition to acoustic insulation, it also plays the role of thermal and refrigeration insulation. This foam is equipped with glue and doesn 't need any adhesive to connect to the desired location . Because it can be easily used for all types of gypsum, glass, wood and metal surfaces.
Silent foam is a type of closed cell insulation that is used along with rock wool sound insulation as an excellent choice in wall insulation. foam foam is not an appropriate insulation for sound absorption And it does not have the desired result and must be used with another insulation to be effective.
