When building a house, there are several important aspects that you should think about beforehand. One of them is soundproofing.


Due to their design features, the veneer panels have good soundproofing properties. Absolute silence inside the house is difficult to achieve and should not strive for this. Comfortable rates for humans are considered 20 dB.


Once the construction of your home has been erected, follow the stages of exterior and interior decoration. It is at this stage you need to understand is the best choice of materials to ensure an environment of full acoustic comfort for you and your loved ones.


To achieve this comfort, you should protect the space from unwanted noise influences. Noise is such a chaotic combination of sounds that are neither good for information nor beneficial to humans. On the contrary, they can be a source of severe irritation and harm the human nervous system.


There are several types of noise, which differ in their nature and propagation, so the methods and materials used to eliminate them are also different:


– Airborne noise spreads directly through the air. Most often in houses, such noise is created by loud voices of people, music, barking dogs, working household appliances, the hum from the freeway, etc. From such noise, the SIP-panels will perfectly protect the house. Vulnerable are only door and window openings. Their noise insulation is worth taking care of. laminated glass and properly chosen doors will reliably protect you and the sounds from the street or the neighboring rooms will not bother you.


– Impact noise – the name says it all. It can be caused by the sound of footsteps, moving furniture, hammering, etc. It is not easy to localize this type of noise. The main source of such noise is the ceiling, and the basic sound insulation measures should be applied there. To neutralize this noise, elastic porous materials are used as substrates to dampen possible vibrations. This can be foam rubber, cork, dense polystyrene foam, polyurethane, porous PVC, using sound-absorbing layers in the finishing and apply sound-absorbing elastic substrates between the bearing structures of the house, make “floating floors”.


– Structural noise occurs when vibrations are transmitted through the bearing structures of the house, its walls, and floors. It is not as important what causes this noise as understanding that because of the rigid links between the walls and floors, it is transmitted very quickly and with virtually no loss. Structural noise can be eliminated by using elastic cushioning material between the joints of the bearing elements. The connections to ceilings and load-bearing walls should be made with damping tapes and in a false ceiling, constructions use elastic hangers that dampen vibrations.


Soundproofing always requires a comprehensive approach. Because noise can be generated by a wide variety of sources and can be outside as well as inside the house. Therefore, it is more effective and cheaper to address sound insulation issues at the design and construction stages. So even at the architectural design stage the rooms that are particularly in need of sound insulation (bedroom, study, children’s room) should be located far from the ones that are the source of unwanted sounds (playroom, workshop, utility rooms, etc.). The maximum distance from the protected rooms should be placed and household appliances, forced ventilation units, pumping stations.


To make the house quiet and comfortable, soundproofing should be considered as a complex system where all elements are interconnected and matter.


Options for soundproofing walls in the SIP houses:


An effective method of protection against airborne noise is to create a multi-layer structure consisting of several alternating layers of hard, dense, and soft building materials. Multilayer construction is achieved by making external and internal finishing of SIP walls, which are already multi-component material and effectively insulate from the air noise in the high-frequency range.


If the house is located in a noisy area, it is better to choose a ventilated facade. In this case, the finishing of the walls is carried out with cladding materials that are mounted on the purlins. Between them and the wall surface remains air gap muffles a variety of noises.


Walls clad with plasterboard inside have acoustic properties. When using brackets and guide profiles for mounting drywall, it is necessary to attach them to the walls through elastic spacers. The sheets should be screwed with a gap from the floor and ceiling, which will subsequently be sealed with a non-hardening sealant.


Options for sound insulation of floors in SIP houses:


Two types of structures are used as inter-floor ceilings:


– Beam slab (rectangular cross-section beams and I-beams);


– SIP ceiling panels.


Regardless of the type of flooring, a comfortable level of sound insulation is achieved by performing a set of works:


Ways to protect against structural noise.

It is possible to avoid the transmission of structural noise along with the bearing structures by using shims to protect the joints of bearing elements. It is necessary to use a special sound-absorbing tape in the connections “wall-beam” and “beam-RPB”. This elastic tape, glued on every floor beam, creates an acoustic decoupling at the joints “wall-beam-RPB”. The tape absorbs the impact noise energy from the upper flooring onto the floor joists and walls of the first floor.


This type of work is performed at the stage of installation of the flooring.


Suspended ceilings can help in the sound insulation of the floor. The air gap between the ceiling space is involved in the localization of noise. To avoid structural noise and resonating vibrations, the profiles must be fixed to the ceiling with elastic hangers. It is recommended that vibration-damping spacers are installed underneath the hangers. Hanging ceilings that are not attached to the ceiling at all and are made of non-resonant PVC films and fabrics have proven effective.


Ways to protect against airborne noise:


When all communications are laid in the interbeam space, you can proceed to additional measures of sound insulation of air noise and fill the interbeam space with materials with a fibrous or porous structure. The thickness of the sound-absorbing material used in the construction is 50 mm.


In SIP panel ceilings, the airborne noise is insulated with polystyrene foam with a thickness of 180 mm.


Ways to protect against impact noise:

The “floating” floor system has high sound-insulating properties. This system is effective in protecting against both impact noise and airborne noise in the floor between the floors. The main feature of all types of “floating” floors is the absence of rigid fixation with the base. The design of “floating” floors is multi-layered. It consists of different materials that form a single structure:


Foundation. Bearing structures: beams, OSB, SIP panels.

Soundproofing layer. For insulation against shock noise porous and fibrous materials with a small value of dynamic modulus of elasticity are used.


“Floating” layer. In a prefabricated “floating” field, a rough deck (plywood, OSB, particleboard) is placed on a layer of a resilient material with finished flooring. For a concrete “floating” floor it is necessary to make a reinforced screed of 50 mm, in which you can integrate a system of “warm water floor”.


Classic floor coverings – linoleum, carpeting, cork – perfectly dampen and absorb noise. Laminate and parquet flooring will improve the acoustic situation if quality underlayments are used.
