Alenor XLPE Acoustic Insulation Tape

ALENOR XLPE is a self-adhesive acoustic tape made of chemically cross-linked polyethylene foam (XLPE). It is applied between drywall framing profiles and the load-bearing structure – walls, floors and ceilings – to break the transfer of sound and vibration through the joints. Without it, the metal profile sits tight against the concrete and the partition acts like a drum, amplifying noise.

The flexible foam evens out irregularities, ensures a tight fit, compensates thermal expansion and does not rot, smell or soak up moisture like ordinary foam rubber.

Technical data

• Material: chemically cross-linked PE foam (XLPE), high-tack adhesive, release paper
• Thickness: 3 mm
• Sizes: 30, 70 or 100 mm × 30 m
• Density: 30 kg/m³ (± 10 %)
• Tensile strength: ≥ 150 kPa
• Adhesion to steel: ≥ 14 N/25 mm
• Service temperature: −40 °C to +75 °C
• Application temperature: +5 °C to +40 °C

Where to use it

• Drywall partitions and ceilings – under UW and CW profiles where they meet walls, floor and ceiling.
• Floors – separating the floor build-up from walls to reduce impact noise.
• Pipes and service boxes – between pipe, clamp and wall so vibration does not pass into the structure.
• Metal and timber frames – wherever two rigid elements touch and carry sound.

How to apply

1. The profile must be clean, dry and degreased.
2. Cut the tape to the profile length and remove the release paper gradually.
3. Apply the tape to the profile base so it covers the whole contact surface.
4. Fix the profile to the wall or floor so the tape stays compressed between profile and structure.

Which width should I choose?

Choose a width close to the profile: 30 mm for pipes and narrow elements, 70 mm for 75 mm profiles, 100 mm for 100 mm profiles and floor edges.

Frequently asked questions

Does XLPE tape replace acoustic boards?
No. The tape stops sound travelling through joints; the cavity still needs mineral wool or another sound-absorbing material.

How do I stop drain pipe noise?
Use the NSP(SOFT) PRO sound insulation kit on the pipe itself and XLPE tape at the clamps.
