Acoustics

Our roof and wall cladding systems have been tested at a number of independent test houses throughout the UK, including Sound Research Laboratories (SRL) in Suffolk. The tests have included determination of weighted sound reduction and rain noise levels for standard systems as well as absorption coefficients when incorporating perforated liner panels.

Our Technical Team can also produce project specific predictions for standard multilayer constructions. More complicated build-ups can be outsourced to recognised independent specialists familiar with these types of cladding systems.

Based on standard U-values the Twin-Therm® system achieves the following weighted sound reduction figures without any enhancements:

  • Twin-Therm® roof 0.4mm liner – 42dB
  • Twin-Therm® roof 0.7mm liner – 45dB
  • Twin-Therm® Wall 0.4mm liner – 39dB
