Product Benefits

  • Acoustic barrier for a sound reduction up to 11 dB
  • 100% flat irrespective of the Relative Humidity
  • IAQ: Class A

Caracteristics & Performance

Sound insulation

  • Acoustipan® reduces lateral transmission between two spaces.

  • Tonga® A40 : Dn,c,w (C;Ctr) = 28(-2 ;-6) dB
  • Tonga® A40 + Acoustipan® : Dn,c,w (C;Ctr) = 39(-2 ;-7) dB

Fire reaction

  • According to EN 13501-1: Euroclass A2-s1, d0.

Use in plenums or attics

  • Inaccessible attics and the existing gap between the floor and the suspended ceiling must be filled with materials featuring a M0 fire protection rating or by firewalls with a 15-minute rating.
  • The maximum surface of these spaces must not exceed 300 m², and the longest side must not exceed 30 m.
  • This is not required if the empty spaces above are protected with an automatic fire suppression system or located inside a compartment.

Humidity performance

  • 100% flat irrespective of the Relative Humidity.

Thermal resistance

  • According to EN 13162, Acoustipan® panels offer thermal resistance of:
Thickness Thermal resistance
80 mm 2.35 m² . K/W m². K/W


Environment and health

Before After


Since July 1, 2013, the manufacturer has indicated the CE marking on its products and provided Declarations of Performance (DoP) in pursuance of the Construction Products Regulation.
The declaration of performance expresses the performance of construction products in relation to the essential characteristics of those products in accordance with the relevant harmonized technical specifications. Declarations include the following performance characteristics:

  • Reaction to fire
  • Release of formaldehyde
  • Flexural strength
  • Acoustic absorption coefficient (αw)
  • Thermal conductivity

The Declaration of Performance (DoP) alone provided by the manufacturer is sufficient evidence of the fire reaction performance of our products and can be used in place of the fire classification test reports.
