To sem se tudi že jaz spraševal, ampak tudi ko gledaš na YT resne delavnice (Retropower UK npr.) celo notranjost polimajo, pa glede na projekte pri njih ni videt da ne bi ravno obvladali.

 
Standard 3: Efficiency

Vibration damping materials function the best if they cover 60-80% of the section’s surface. 100% coverage is obsolete and adds unnecessary weight. When applied, material needs to be meticulously pressed onto the metal leaving no air bubbles underneath. Any portion of vibration damping material that is not in permanent contact with metal surface of the frame is adding weight without any effect. If you get into a complex area of the frame, it is not necessary to cover every last square inch.

Sound insulating and absorbing materials are different in this aspect – recommended coverage is 90-100% of the surface, and should cover any complex areas as completely as possible, inclusive of any unused holes. These materials are very light in comparison to the vibration damping counterparts and are only limited by the amount of space available in the installation area. For example within the roof there’s only a few millimetres of space available, so only a thin material can be used, most doors on the other hand are relatively spacious and have a lot of space for the thicker and more powerful insulators and absorbers.

Improper installation of insulating materials will lead to reduced efficiency, or even complete failure.

Standard 4: Too much

When it comes to soundproofing it is possible to have too much of a good thing. Excessive use of vibration damping materials is not only detrimental to the total added weight, it can even increase the noise level in the car. Based on basic physics – increasing mass of a vibrating object lowers the frequency, but increases amplitude of vibrations. This can generate a new low frequency ‘humming’ noise to appear in the car. Balancing the right materials in right quantity is the art of soundproofing.

 

 

Tole recimo sem na hitro našel. To govorimo o bitumenski foliji...

Je odvisno za kaj delas izolacijo in pa seveda kolko € mislis pustit.
Nekje je treba potegnit crto, ker to gre lahko v take detajle in cifre da glava pece :ok
