A significant amount of external noise arrives through the door to the car's salon. It is after noise insulation car doors There is a tangible decrease in external noise. In addition, the doors can always be completely "to do" and do it yourself. There are no supernatural difficulties here.
Before noise insulation - disassembly doors
The first stage is a complete disassembly of the door, namely, the removal of the external sheaving. This stage is the most difficult, but not the most difficult. It is necessary to remember (and it is better to write), what kind of screw or the screw was in what a hole in order to make it easier to make it easier to build a reverse door assembly. The mechanism of opening and closing the door, as well as the device of the window regulator, can not be removed, because put them back extremely difficult. These nodes will not interfere with self-insulation doors.
The second stage it is necessary to clean the metal of the door from the factory noise insulation and the wall of the door, close to the outside - from the factory anti-corrosion processing. It is important that the surface is clean and degreased - the White Spirit will help in this. The main thing is not to scratch the paint in order to avoid corrosion.
Getting to noise insulation doors
Next follows the inner side of the door (side to the road) to plunge the vibration-fixing material. Gold Vibroplast is best suited, while you need to try to take the maximum area, which technical holes will allow in the door. It is not very convenient to be done there, so not to scratch your hands about sharp edges of the technical holes, it is better to work in cotton gloves. Door Amplifier is not needed. Currently, AERO and AEROPLUS from STP are increasingly used to vibration insulation of metal. They are easier than the Vibroplast Gold, which will have a positive effect on the resource of the door loops. The high KMP will make the door "wooden" onto a knock, close the doors will become like a car above the class with a pleasant sound "PHF" instead of BDZYN. In addition, the new Aero line has been expanded the temperature range, which is especially important for the cold season.
Opposite the dynamics, it is recommended to stick a circle from the bitoplast so that the speaker becomes better to play and the sound waves reflected from the door are not accepted. You do not need to damop the entire surface of the bitoplast, because This material absorbs moisture, and breed the dampness inside the door - the first step towards corrosion. The second layer on top of the vibration insulation used to be splated for silence, since the usual emphasis could not cope with moisture appearing in the door during the rain. In addition, on some cars, Splin 8 mm could not withstand the operating conditions and tritely dug out due to non-water-resistant glue. Now the material of the new generation is available - the focus of premium, which is completely not afraid of water: outside the material is covered with a black film, and from the reverse side, a moisture-resistant adhesive layer of green color is used. Therefore, the inner part of the door can be safely accumulated by a premium accent.
For music lovers, the use of any material (except for vibration insulation) inside the door is undesirable, so because of it, unpleasant extensions will begin to appear and the quality of music will deteriorate.
If the quality of the sound of acoustics is not important, then the entire inner surface of the door should be tightened with an accent of premium or splane on a mastic basis. It is necessary to glue the maximum slice, ideal - one whole one. Will be quieter.
Vibration Isolation of All Door Holes
Go to the inside of the door - close to the cabin. Here are two options here.
If the car is preparing for the installation of powerful acoustics, and from Midbas installed in the door, await a juicy game, then it is necessary to close the process hole in the door with a dense and solid material. Depending on the sizes of the holes, sheet aluminum or dense fiberglass can be used, which is then covered with a powerful vibro-reader, for example, bimavo bomb premium or visomat. It is important to improve the quality of the sound of music - from the door there should be something like a rigid closed box. It is important to check the performance of the door opening mechanism and windows - so that nothing bothered. The use of bimaste when embelling technological windows can significantly increase the mass of the door, you have to choose: or loops, or music.
If the sound quality of acoustics is not important, then the technological windows are closed with waterproofing: it is important that the moisture does not go into the cabin. For this will suit STP AERO: lightweight and durable to break. Many slightly glue vibration insulation is not worth it, because Increases the mass of the doors and loops may not withstand heavy loads.
There is also a compromise option applied to noise insulation of civil car doors: we close the technological holes in the Foil Watch, and then rolling the Aero Plus on it. Thus, we obtain sufficient rigidity for the acoustics of medium power, excellent waterproofing and a small increase in mass.
Then it should be saved this surface of the door to the material to the focus or focus of Premium, as a last resort - bitoplast 10 mm, making the necessary slots to all mechanisms. It should be accumulated by an area close to 100%, leaving space for wires (if the power windows is installed) and the speaker.
Noise isolation of door sheathing
It is finished with the door, go to its trim. On the surface of the trim, it is recommended to glue several pieces of vibration-pulp (enough STP Aero or Silver vibroplast) to reduce the vibrations of the trim. Special attention should be paid to the joints in plastic. Then the entire surface of the skin is covered with a biplast 10K with a margin along the edges of several centimeters. After trimming the bitoplast on the contour of the trim, it will perform the role of antiskrip - all the stuffing knobs about the door itself will disappear. Another option is possible: in the places of fitting the door sheathing to the metal of the door to the trim on its perimeter, Madeline strips are glued, and the inner part of the trim is filled with biplast.
On this noise insulation of the doors of the car do it yourself Finished, you can proceed to the installation of the trim back. On different cars, the door dismantled in different ways, but the principle is the same everywhere. With noise insulation, the doors from the splash is better to completely refuse, because Inside the door from it only disadvantages (the quality of the sound of acoustics is spoiled, it can fall off from moisture), and outside (between the bitoplast layers) it can interfere with the reverse assembly.
As a result of the "Shumkov" doors in the car, it will be sweeteringly quiet, and the doors will be closed easier by increasing the mass.
