Do-it-yourself experts recommend taking home-made materials for soundproofing the trunk of a car. According to the ratings, the best choice here is the Premium line of the StP brand (Standartplast company).
The feeling of comfort when driving a car consists of dozens of factors, but silence in the cabin is recognized as one of the leading ones. Let's figure out how the soundproofing of a car trunk affects it, and whether it needs to be done at all.
Soundproofing car trunk: what to do?
The luggage compartment in any car is one of the significant sources of extraneous noise. Sounds can penetrate into the cabin from the elements of the exhaust system, suspension parts, contact of the rear axle tires with the road. The inevitable vibrations of the body cause the stored cargo (tools, spare wheel, jack, small parts) to emit knocks and squeaks. The luggage compartment lid sometimes does not fit snugly. Sounds from the street penetrate through the gaps inside the car.
Noise isolation car STP
An additional reason to wrap body panels with insulating materials is the detection of pockets of rust in hidden areas under rugs or factory coating. If you glue the trunk in the car for sound insulation with high quality, then problems with unprotected body metal will also be solved. Improved protection from the cold outside.
Do it yourself or give it to the service station
Entrusting body wrapping to car service workers is a good idea, since this business will require practical experience, a set of special tools, and knowledge of some tricks for cutting materials. However, if you are not too lazy to study the topic, then soundproofing the trunk of a car with your own hands is also quite possible.
Soundproofing a car
Key success factors:
- the right choice of suitable insulating coatings;
- exact observance of the sequence of operations;
- high-quality cleaning of body surfaces from dirt and oil and fat stains;
- accuracy when working so that all folds and bends are properly pasted over.
If you are guided only by considerations of price, then self-insulation will not help the car owner save a lot of money. After all, service specialists, behind whom there are more than one hundred completed orders, soundproof the car quickly, without making mistakes and with minimal material consumption. Unlike them, the home master does not know all the secrets, does not have patterns for cutting, so the work will take much more time.
Proper soundproofing of the car trunk with your own hands
If, nevertheless, a decision is made to glue the sound insulation in the trunk of the car yourself, then the universal step-by-step instruction is as follows:
- Remove the entire luggage compartment trim.
- Prepare and clean metal surfaces of body parts.
- Lay the first anti-vibration layer on the rear wheel arches.
- Apply a second layer of noise absorber to the rear arches.
- Glue the floor of the luggage compartment first with vibration isolation, then with sound-absorbing material.
- For best results, apply a final third layer of soundproofing with a slight overlap of adjacent strips.
- Carry out pasting the rear panel of the body and the trunk lid in two layers.
It is useful to decipher the features of individual operations in more detail.
Soundproofing materials
Do-it-yourself experts recommend taking home-made materials for soundproofing the trunk of a car. According to the ratings, the best choice here is the Premium line of the StP brand (Standartplast company).
Removing the old trunk lining
Specific varieties for each layer:
- The first vibration isolation is a sheet polymer-rubber with foil reinforcement StP Aero, Alyumast Alfa SGM or analogues.
- The second layer is noise-absorbing - Biplast Premium or Isoton from StP, Bibiton SGM or other polyurethane foam sheets with an adhesive layer.
- The third acoustic (sound-absorbing) layer. "Violon Val" SGM, Smartmat Flex StP and other sheets of elastic foam rubber that absorb noise and squeaks.
How to paste over plastic trim and trunk lid
For high-quality sound insulation of the car trunk lid and plastic parts, the main thing is to clean the surfaces well from dirt, anti-corrosion mastic and remnants of the factory “shumka”, if any. Use solvents, white spirit for this. Stick a layer of light vibration absorber (optimally - "Vibroplast" StP), without overloading the structure with excess weight. Lay sound-absorbing material on top (“Accent” or “Bitoplast”).
We process body metal
Proper soundproofing of the trunk of a car assumes that all protective layers are glued as tightly as possible to each other without air gaps and bubbles. To do this, degrease all surfaces with white spirit, use an industrial hair dryer to preheat the coating to 50-60 ° C (this gives the material greater plasticity) and be sure to roll the Shumka to the body with a roller, not missing the bends and edges of the panel contour.
