Heat and sound insulation — Toyota Vista, 1.8 liter, 1995

As many Toyota users already know, the wonderful cars of this Japanese automaker suffer from one small drawback. There is practically no normal Shumka.
No, do not think that only one bare iron body and that's it. Vibration-loaded body elements always have vibration damper blotches, cellophane oilcloth is glued on the doors (either from dust or from moisture), in some places you can find thick porous pieces of sound-absorbing material (especially on the engine shield). But still, the Germans make Shumka better. This is purely my subjective opinion, everyone has the right to agree with it or not.
Therefore, it was decided to purchase heat-noise-insulating materials from STP (StandardPlast) and glue Vista more seriously.
To begin with, the back seat was completely removed, bare metal was opened, which was completely cleaned of dust and dirt that had accumulated there over the years of operation. Further, the vibration-absorbing material Vibroplast M2 was glued to the iron of the body (It is a foil material on a bituminous adhesive basis).

More attention should be paid to vibration-loaded parts of the body (shock absorber struts, for example) and it is better to glue them in two layers, making overlapping joints.

To do this, it had to be carefully cut out, since initially it is sold in pieces of about 1m * 1m.
Next was to take a roll of Isolon (Splen) 4mm thick. It is a noise-absorbing porous material with an adhesive backing.

It must be glued immediately and carefully, since it can no longer be torn back (unlike vibroplast).
Therefore, this is one of the most hemorrhoid parts of the work.
"Everything about everything" took about 3-4 hours of work ... thanks to my faithful assistant and colleague ... Without him, I would definitely have been tormented ...

Next, let's take care of the doors. I will give an example of one front door, since in principle the work on the rest is identical.
So, the door is completely disassembled, the entire lining is removed, the standard polyethylene is removed, which sealed the window in the outer shell of the door. The door is carefully cleaned of dust and dirt accumulated inside it, special attention is paid to the drainage holes inside the door, in the lower part, through which the moisture that has got into the door will happily drain to the street. They must be clean and not clogged.
Further, Vibroplast M2 or Silver or Gold is glued to a dry and clean inner shell, at the discretion of the owner. The last two have a significant plus that they are soft, respectively, it is easier to push them through the windows of the door and glue them onto the outer shell.

Further, noise insulation, the same Splen or similar materials, are glued on top of the vibroplast. With him, again, the most hemorrhoids, since he instantly sticks to something and then no longer rips off, but breaks. Therefore, it was cut in advance into the necessary pieces, inserted into the door, and there already, “in place”, the film covering the adhesive layer was removed and the piece stuck in place ...

The remnants of the material was glued to the inner upholstery of the door. This is purely a safety net so that the material is not thrown away in vain.

By the way, the photos show a piece of standard Toyota Shumka.

Now we are taken for the inside of the door shell, because it also has vibrations that are perceived by a person as noise.
Pieces of Vibroplast are figuratively cut and glued to the joint on the inside of the shell. The work is a little dreary (since there are a lot of all kinds of wires, fasteners, windows on the inner shell), but quite easy, it is done in 20-30 minutes.

I think it turned out pretty good and good quality.
A regular film is also glued in place, it has its own adhesive layer around the perimeter, so there is nothing to collective farms here. I can’t say for sure why Japanese engineers foresaw it, most likely so that the moisture that enters the door through the upper rubber bands near the glass flows to the bottom and leaves through the drainage holes to the outside ...

Next, the door is assembled in the reverse order and enjoy the resulting effect. I will say right away that the door will become heavier by 2-3 kilograms, this will be especially noticeable when closing. The hinges will most likely easily endure a slightly increased load, since the weight of the noise is distributed over the entire area of ​​u200bu200bthe door and the load on the hinges will not be very large. The car became much quieter, the amount of noise coming from the street decreased. Plus, in winter weather, heat is retained in the cabin longer and the cabin warms up faster, since this sound insulation will still partially play the role of heat insulation.
