Insulit 55+ - Thin and economical acoustic membrane - Insulco

Insulit 55+ is the economical acoustic underlay in the insulit range designed to limit the transmission of impact and shock noise between floors .

It is placed under a floating screed in single layer or double crossed layer for even higher performance.

Insulit 55+ is part of the "eco line" range offering an economical solution but of recognized quality and technology .


Insulit 55+ is a closed microcell physical cross-linked polyolefin foam with a pyramidal structure on one side to achieve low dynamic stiffness. Recent tests have been carried out at the BBRI according to the EN ISO 717-2 standard and attest to its performance.

Benefits :

  1. Attenuation of impact noise.
  2. In roll, easy and fast installation.
  3. Economic.
  4. Physically cross-linked polyolefin: guaranteed longevity.
  5. Micro closed cells.
  6. Thin, light and flexible.
  7. Low dynamic stiffness: acoustic performance.
  8. Low creep.
  9. Recent CSTC reports = guaranteed results.

Facility :

Insulit 55+ - First step of installation.

1. Create a cleaning screed. Failing this, provide sand or cement coves at the crossing of the pipes.

Insulit 55+ - Second stage of installation.

2. Unroll the insulit 55+ with an overlap of 5 to 10 cm.

Insulit 55+ - Third stage of installation.

3. The maintenance of the overlaps will be ensured with the attached tape.

Insulit 55+ - Fourth stage of installation.

4. Go up ±15 cm against the walls before making the screed.

Insulit 55+ - Fifth stage of installation.

5. Create a screed at least 5 cm thick on the insulit 55+ (minimum 6 cm when laying in double layer).

Insulit 55+ - Installation Step Six.

6. Cut off the excess insulit 55+ after laying the final covering.

Features :

  • Material: Physically cross-linked polyolefin.
  • Thickness: ± 5.5 mm (under 1.5 kPa).
  • Color: Silver Grey.
  • Dynamic stiffness:
    • s't ≤ 61 MN/m³ (1 coat) (EN 29052-1).
    • s't ≤ 39 MN/m³ (2 layers) (EN 29052-1).
  • Compression: ≤ 5% under 2 kPa (tolerance ≤10%).
  • Thermal conductivity: λ ≤ 0.038 W/m K.
  • Weight: ±150gsm.
  • Size of a roll: 50 mx 1.1 m.

Attention :

  • For logistical reasons: orders that are too small or too light may be declined. In general, the minimum order is 20m², but we are still listening.
  • All orders with problematic or too weak logistics can be picked up directly by the customer.
