dB Acoustic Lag 100
dB Acoustic Lag 100 is a high-mass acoustic lagging product designed to improve the sound insulation and absorption of pipes, ductwork, panels and similar building-service assemblies.
The product combines a dense 10kg/m² acoustic barrier with a fibreglass quilt and a Class 0 aluminium foil facing. This multi-layer construction helps reduce sound transmission while remaining soft and flexible enough to conform closely around existing structures.
dB Acoustic Lag 100 is suitable for demanding residential, commercial and industrial applications where pipe noise, duct breakout noise or vibration through lightweight panels needs to be controlled.

How dB Acoustic Lag 100 Works
Pipes, ductwork and lightweight panels can radiate airborne noise into adjoining rooms and occupied spaces. dB Acoustic Lag 100 adds significant mass directly to the existing structure, helping resist sound transmission.
The fibreglass quilt provides an additional absorptive layer, while the flexible construction allows the product to fit closely around the original surface. The aluminium foil facing protects the acoustic build-up and provides a durable outer finish.
Acoustic Performance

|---|---|
| 63Hz | 17.8dB |
| 125Hz | 17.6dB |
| 250Hz | 22.1dB |
| 500Hz | 43.6dB |
| 1000Hz | 54.3dB |
| 2000Hz | 58.3dB |
| 4000Hz | 62.8dB |
| Weighted Sound Reduction Index | Rw 38dB |
| Average Sound Reduction Index | 40dB |
Installation Guide
- Ensure the pipe, duct, panel or enclosure is clean, dry and free from dust, oil and loose material.
- Measure the area requiring treatment and allow additional material for joints, overlaps, bends and branches.
- Cut the lagging to the required size using a sharp heavy-duty knife and straight edge.
- Fit the material closely around the pipe, duct or panel, keeping the fibreglass layer in intimate contact with the original surface.
- Secure the lagging using a fixing method suitable for the application.
- Butt adjoining sections together closely and avoid leaving gaps.
- Seal all joints, overlaps and exposed foil edges with aluminium foil tape.
- Pay particular attention to bends, couplings, brackets and penetrations to maintain continuous coverage.
For best results, cover the service continuously and seal every joint. Gaps, loose sections or unsealed edges can reduce the overall acoustic performance of the installation.
Complete the Installation with Aluminium Foil Tape
Seal joints, overlaps and exposed edges in the dB Acoustic Lag 100 system using our heat and light reflective aluminium foil tape.
Installation Tips
- Use a sharp knife to create clean, accurate cuts.
- Wear appropriate personal protective equipment when cutting and handling the fibreglass layer.
- Keep joints tightly butted together.
- Seal joints and exposed edges with aluminium foil tape.
- Maintain continuous coverage around bends, couplings and branch connections.
- Avoid puncturing or damaging the foil facing during installation.
- For complex mechanical, fire-sensitive or high-temperature applications, obtain project-specific installation guidance.
Typical Projects
dB Acoustic Lag 100 can be used in houses, flats, apartment developments, hotels, offices, schools, hospitals, commercial buildings, factories and plant rooms where pipe, duct or machinery noise needs to be controlled.
