requirements for door constructions with rising consumer demands for convenience and comfort of the living space.This mainly affects the performance.For example, providing a warming and paintings hydroprotective function has become a prerequisite for production.There is a growing level of acoustic comfort and entrance doors, as evidenced by the introduction in the construction of new insulation materials Noise Cancelling.
Noise protection factors
Technologies designs supply insulation qualities often intersect.Thus, the device parameters are combined heat and waterproofing, which have metal entrance door.Soundproof quality can also be achieved in combination with other functions, thanks to one material.The main secondary factor in improving the efficiency of the insulation structures is their tightness.Accordingly, the master note the following structural aspects influencing sound insulation:
- type of material used in the creation of leaf;
- characteristics of the filler;
- density and accuracy of fit;
- the overall quality of the installation;
- size of the seal;
- inclusion in the threshold and its properties.
Each parameter has an impact on the overall function of the insulation of the door system.Still, the main contribution technologists, originally designed doors in the apartment, soundproof characteristics of which comply with the standards.
How is sound insulation?
The list of the key tasks of the developers of such structures include the establishment of a door "pie", which will act as a reliable barrier to the noise in the stairwell and street.For this fabric vested different functional elements.
One of the main conditions to achieve tightness of doors overlapping acts of structural gaps.An ideal arrangement of all elements of the web provides a foundation for sound insulation.The empty niches filled with damping materials and trim are made from MDF.The role of internal isolator is difficult to overestimate - even its variants will be considered.By the way, soundproof doors, metal on the outside often are finished in the same MDF or other wood-base product.
This set of measures is mandatory, but the tools and techniques to ensure zvukopodavleniya may vary.Now consider the features of sound insulation of wooden and metal door panels.
wooden soundproof door
While the front doors are usually associated with the metal sheets in the design, modern technology allows the wood and give a sufficient level of reliability for use as the main barriers to the house.And in terms of the acoustic properties of some breeds natural material initially surpass steel counterparts.
In particular, soundproof doors are made of wood are capable of providing sound insulation up to 32 dB, and preserving a high degree of security.Frames of paintings of such models manufactured from plywood, and are mainly used pine varieties.Also designs are complemented by internal trim.As an act of filling the aluminum plate and chipboard.Outdoor decorative finish can be provided with natural veneer or artificial turf.
metal acoustic doors
fundamental difference of manufacturing of steel anti-noise model is to focus on filling the interior space.This is the filler is the main barrier to external sounds.
As a rule, formed the basis of sound absorbing mineral wool or foam.As the cost of both options are almost equivalent, but in terms of noise protection the first type of filler profitable.In addition to the basic insulation package is taken into account and related materials, which are also complemented by the doors to the apartment.
sound insulation properties, in particular, determine the decorative materials, such as imitation leather and MDF panels - the most effective means in terms of finishing zvukopodavleniya.
increased noise reduction
clear separation model with the normal and there is no soundproofing, however, if the principle of "commodity product discord", some differences can be identified.
This obvious difference is expressed in numbers - the most effective acoustic protection will prevent noise of 40 dB.This is achieved by incorporating into the design of one of the following types of excipients:
- mineral wool;
- polystyrene or foam;
- composite insulators;
- soundproof panel with foil backing.
There are also models with other materials in the cavity, but this set is most relevant at the moment.It is worth noting that the list of benefits that have doors with high sound insulation, also includes effective insulation.
Safety and soundproofing
may sound implausible, but the isolation is often a technological tool that reduces the protective function of the entrance doors.This is a delicate moment for ordinary users to trace the relationship can be difficult.Anyway, the producers are forced to maneuver between the two properties, covering all available means of improving the insulation.
Insulators occupy a large part of the space in the web that does not allow the use of additional funds have mechanical protection, including to increase the thickness of the metal sheets.Yet producers seek to combine two qualities, providing optimum product for durable and comfortable use.
Additional noise protection
In order to achieve optimum parameters of acoustic doors play a role not only the characteristics of the web, but also the quality of installation associated with the construction of the decoration.If not installed noise-insulated door to the apartment may not show their technical merit (by the way, it depends on the installation zvukopodavleniya 35% efficiency).
To begin to maximize seal the gap between the frame and the opening.This construction is silicone or foam.Door box is subjected to special insulation, and between the exterior finish and a steel plate should pave the porous material, for example, termofol.Installers are also advised to carefully check the relative density mounting frames and thresholds - the quality of installation.Each of these areas can affect the sound effect both for the better and for the worse.
How to choose a quality doors with noise insulation?
The selection process is quite simple and even without specialized training and laboratory tests can be found on the optimal characteristics of the doors in the apartment, sound insulation properties that meet specific needs.
review should begin with a sealant.In this high-quality design element it has a solid shape and adheres to the steel sheet.Next should evaluate how well the closed shutters on the openings and is securely integrated peephole.All the furniture, which is built to install a box, should be thoroughly checked.
Perhaps the most responsible choice concerns filler.Since it performs the task of thermal insulation, the best solution should be based on a comprehensive set of operational requirements.For example, in one apartment need polyurethane, and the other will be the best choice entrance door to the apartment, sound insulation properties which defines the mineral component.
also important and the presence of ribs.In addition, they improve technical safety, and marked reduction of acoustic vibrations, which can not cope with any finishing material.
Price question
Unfortunately, the cost of high-quality entrance doors, regardless of their functional, is high enough, which limits many consumers.Nevertheless, competition cools entrepreneurial spirit, allowing the purchase soundproof doors from the manufacturer at affordable prices.
So, prices are determined primarily by two factors: the base material (metal or wood) and the level of noise reduction - an average of 32 to 42 dB.Reliable models of wood with the highest level of acoustic protection can be purchased for 40-50 thousand. Rubles.Their counterparts metal more expensive for a few thousand.Budget segment at prices formed in the corridor of 25 to 35 thousand. - Are variants that can provide high protection against noise of 32-36 dB.
