Photo Report of Completed Work
In this article, we will analyze the factory soundproofing of the Toyota Land Cruiser 250 Prado, and present a photo report on the work done on additional soundproofing with StP materials. First, we will dismantle all the interior elements to evaluate the standard insulation. It is completely absent from the ceiling and doors. Vibration insulator fragments are applied to the floor and in the luggage compartment using the fusion method over an area of about 20%.
Roof Sound Proofing

The ceiling is one of the main parts of the body, occupying a large area through which mainly noise from oncoming air flows during movement and sounds of precipitation penetrate. For the ceiling, we use lightweight, highly effective 2.3 mm StP material, which helps to get rid of most noise. The second layer is a porous sound absorber Biplast Premium, which cuts off medium and high frequencies.

Roof Sound Proofing

Advantages of car ceiling soundproofing

  • Reduction of aerodynamic noise
  • Muffling of noise from rain and other weather conditions
  • Improvement of thermal insulation properties
Floor Sound Proofing

Advantages of car floor soundproofing

  • Reduction of aerodynamic noise
  • Reduction of vibration load on the car body
  • Muffling of noise from snow, gravel, sand and other road conditions
  • Improvement of thermal insulation properties

Boot Sound Proof

Procedure for soundproofing the trunk of a car

  • Dismantling the trunk trim
  • Removing the factory vibration insulator and glue
  • Degreasing the surface
  • Application of materials with careful rolling

Boot Sound Proof

We securely glue the StP Gold and Bromo materials. On top, we roll the combined Bromo sandwich, which combines the functions of sound absorption and sound insulation. It is also necessary to insulate the rear fenders, since in the internal cavities, sound waves can overlap and amplify, reflecting off the walls. StP Bromo and Biplast Premium materials will cope with these negative sound phenomena.

Doors Sound Proof

Procedure for soundproofing car doors

  • Remove the inner door trim
  • Remove the factory vibration isolator
  • Clean and degrease all internal surfaces
  • Apply materials in 3 layers
  • Roll them carefully with a roller
  • Assemble everything in reverse order

Boot Lid Sound Proof

We installed the StP Biplast sound absorber on the plastic lining. We degreased the plastic beforehand, then glued the sheet material onto it, avoiding strong tension.
