Pyrotek has done installations in some iconic buildings like Burj Khalifa Tower for sound lagging in the pipelines, Sydney Opera House and Sydney Olympic skate park for mass barrier technology to reduce the noise level from the external environment significantly.

Various Noise Proofing Solutions:

Wavebar – Wavebar is an economical, easy to install sound barrier that greatly reduces noise transmission between walls, partitions, floors and ceilings in buildings, vehicles and marine applications. Wavebar provides high transmission loss with high tensile strength and uses the latest manufacturing technology. It is a specially engineered material consisting of a mineral loaded polymer and can be supported by a reinforcing fabric to ensure it will never crack and will remain flexible during a lifetime. It is available in 2 kg/m2 to 8 kg/m2 density giving an STC of 23 to 30 dB. Also available are Wavebar Quadzero (foil faced for zero ignitibility) and Wavebar Outdoor (for external applications).

Wavebar Applications –

  • Reduction of traffic and aircraft noises in homes, apartments and offices
  • Partition wall interlining
  • Reduces ceiling noise drastically by eliminating noise from adjacent rooms.
  • Provides privacy and peace of mind in board rooms, consultation rooms, computer rooms, nurseries etc.
  • Floor and ceiling interlining
  • Acoustic doors
  • Soft enclosures for factory fans and machinery housings and enclosures
  • Strip curtains/drapes
  • Vehicles and marine vessels as flooring mats and engine curtains
  • Portable noise barrier screens
  • Mining barrier curtains
  • Noise curtains for jack-hammers, drilling rigs, blasting and pile drivers on

Wavebar is used in the internal wall for making dry wall construction to make the building lighter. It could be used in various combinations with acoustic absorbers and plaster boards to give various STC values as required by the project.

Soundlag :

The trend towards high-density living environments and lightweight building construction over the last decade has required an improvement in the control of noise from waste pipes and general plumbing. Soundlag 4525C, carrying a ten year warranty, is the choice for many leading acoustic consultants, architects and consulting engineers as its quality assured consistent performance guarantees quieter pipes. Soundlag 4525C has been developed as an easy to use acoustic treatment which reduces noise breakout from pipes. The unique flexibility of the polymer-based noise barrier provides superior performance and allows even the smallest pipes to be lagged effectively. It’s independently tested in laboratory conditions and in situ to give proven consistent performance. Leading consultants specify Soundlag 4525C with confidence. Low maintenance with a long service life, the aluminium foil facing provides a robust lifetime surface finish, ensuring protection from damage, and improves fire resistance.


Reapor has been developed to maximise noise energy absorption. It resolves issues of fire, weather aging and contamination damage. Easily maintained, constructed from recycled material, VOC free, Reapor panels are easily fixed and worked. Reapor provides a useful tool in the control of wanted noise in a range of applications. Ideal for all indoor and outdoor environment. It has a high absorption of NRC (Noise Reduction Coefficient) of 0.9. It is fibre free, non-toxic, 100% recyclable and can be painted as per one’s choice.

Worldwide building codes have tightened as the understanding of the risk of fires to human life in buildings has grown. The addition of fire retarders, while reducing time to full ignition, often did not reduce the smoke, creating an early hazard in a fire. Critical areas and certain types of buildings have seen a change in legislation to only accept products with the highest level of fire resistance. Reapor is non-combustible, bringing a fire safe way to control unwanted noise. It has natural resistance to water and sunlight.
