How is the sound insulation effect of light steel villas?
Recently, many people consulting about building houses have asked such questions: Since the walls of light steel villas are so thin, will the sound insulation effect be very poor? Will there be a "thumping" sound when I go up the stairs? Will there be a "rustling" sound on the first floor when someone walks on the second floor? In fact, the sound insulation effect of light steel villas is excellent, and the above-mentioned problems will not occur.
To reduce the transmission of sound between solids, the walls of light steel buildings adopt multi-layer composite structures made of different materials. This not only saves the precious floor space occupied by traditional walls but also achieves better sound insulation performance through the use of different materials, different thicknesses, and multi-layer structures. Sound is sufficiently weakened through different media to ensure effective sound insulation.
Therefore, regarding the question of whether there will be a "thumping" sound when going up the stairs, this will definitely not happen in light steel structure houses. The surface of the stairs will be paved with many materials again, and you will not step directly on the steel plates, so there will be no "thumping" sound when going up and down the stairs, and there will be no "rustling" sound on the first floor when someone walks on the second floor.
About the sources of sound:Before understanding the sound insulation system of light steel villas, let's first look at the sources of sound. Airborne sound is transmitted directly through the air or through building structures; structure-borne sound is produced when building structures vibrate due to impact or vibration.
About sound insulation methods:
Elastic cushion treatment — to achieve shock absorption between the surface layer and the base layer.
Floor ceiling treatment — when the entire floor vibrates due to impact, reduce the structure-borne sound generated by the floor by means of airborne sound insulation.
The sound insulation capacity of the external walls of light steel structure villas exceeds 55 decibels, and the internal partition walls can adopt different structures as needed, with sound insulation reaching 66 decibels. Such sound insulation effect is completely comparable to the requirements of hotels and is sufficient for our normal living.
Sound insulation measures adopted by light steel structure villas:
● Use sound-absorbing materials
● Use sound-insulating materials
● Necessary structural combination measures
Sound insulation composition of light steel structure villas:The impact sound pressure level of the floor is ≤ 70 decibels. However, glass wool is filled between the keels of internal walls and ribbed floors in light steel villas, which effectively blocks the airborne sound frequency part. For impact sound transmitted through solids, tests have shown that filling glass wool can further improve the sound insulation effect of light steel villas to more than 50 decibels. The sound insulation capacity of the external walls of light steel structure houses (wall thickness 160mm) is 65 decibels; the sound insulation capacity of the internal walls of light steel structure houses (wall thickness 140mm) is 44 decibels. The walls of light steel buildings adopt multi-layer composite structures made of different materials, and sound is sufficiently weakened through different media to ensure effective sound insulation.
Sound insulation system of light steel structure walls:Glass wool is filled between the light steel keels of internal walls and ribbed floors. Glass wool effectively blocks the airborne sound frequency part and achieves a certain sound insulation effect. The internal structure of glass wool is loose and intertwined with fibers, with many tiny air pores. It is a typical porous sound-absorbing material with excellent sound absorption characteristics, and has the functions of thermal insulation, sound absorption and noise reduction, and safety protection. It is a material for thermal insulation, sound absorption and noise reduction in steel structure buildings. At the same time, the thermal insulation boards and wall decoration panels of the walls also play a good sound insulation role.
Sound insulation system of light steel structure floors:The floor is paved with 18mm OSB boards, 3mm*80mm nano sound insulation strips, 100mm glass wool, 6mm calcium silicate boards, etc. for floor sound insulation treatment. The overall sound insulation capacity of the door is determined by the sound insulation capacity of the door leaf itself and the gap sealing around the door. The better the airtightness between the door and the door frame, the better the sound insulation effect. Windows mainly adopt the form of broken bridge aluminum alloy windows, the ceiling can be decorated with sound-absorbing panels, and the roof is paved with a composite roof structure. For kitchens, drainage pipes, etc., corresponding sound insulation treatments are carried out according to actual conditions. Many people subconsciously think that light steel structure houses have poor sound insulation, but this is not the case. From the inside out and from top to bottom, light steel villas have a complete and mature sound insulation system that successfully isolates noise from the outside, solves the noise problem caused by square dances, and creates a comfortable and leisurely living environment for you. Therefore, it has become a new choice for many people to build houses.
