STP Splen 8 Silver Bulk Self-adhesive thermal and acoustic insulation 8 mm thick

STP Splen 8 Silver Bulk is a self-adhesive thermoacoustic insulating material designed to improve cabin comfort by reducing noise propagation and limiting thermal dispersion. Made from closed-cell polyethylene foam, it is used as a second layer in soundproofing treatments, in combination with anti-vibration materials. Compared to the 4 mm version, the 8 mm thickness offers greater insulating capacity, making it more effective in applications where sufficient space is available.


What is a closed-cell thermoelectric insulator for

After reducing sheet metal vibrations with anti-vibration materials, airborne noise and thermal dispersion remain. STP Splen 8 acts at this level:

  • reduces residual noise
  • improves thermal insulation
  • limits air passage and secondary vibrations
  • increases overall cabin comfort

The closed-cell structure guarantees:

  • resistance to water and oils
  • stability over time
  • low absorption
  • good thermal insulation capacity

Recommended applications

The 8 mm thickness requires adequate space but offers superior performance. Ideal applications:

  • door panels (trim side)
  • trunk
  • side panels
  • vehicle roof
  • central tunnel
  • internal partitions

It is particularly suitable for:

  • multilayer car soundproofing
  • cabin comfort upgrade
  • car audio systems
  • secondary noise reduction

Less suitable in very tight areas or with reduced tolerances.

Installation and use

Recommended procedure:

  1. apply anti-vibration material first
  2. clean the surface
  3. cut the material
  4. remove the adhesive film
  5. apply with uniform pressure

In case of complex surfaces, it is possible to slightly heat the material to improve its workability and adapt it to more difficult shapes.

The material adheres easily to:

  • metal
  • plastic
  • painted surfaces

STP Splen 8 Silver Bulk is an effective solution to improve thermal insulation and acoustic comfort in multilayer automotive treatments. Thanks to the greater thickness and closed-cell structure, it allows you to achieve better performance compared to thinner materials, making it ideal for applications where available space allows you to fully exploit its insulating characteristics.
