Key TechnicalMetrics for Specifying AcousticSurfacing

When selecting sound-absorbing wall assemblies, specifiers must evaluate fourcoreengineeringmetrics:

1.NoiseReduction Coefficient (NRC):EvaluatedunderASTM C423 /ISO 354. SDPanelsacousticassemblies yieldanNRCrange of 0.75 to 0.85, absorbingup to85%ofincident soundenergyacrossspeechfrequencies(500Hz –2000Hz).

2. Substrate Stability & VOCProfiles: Substrate materialsutilizehigh-densitypolyester fiberormoisture-resistantacoustic core boards toprevent saggingunder fluctuatinghumidity whileensuringzerohazardousairpollutants.

3.FireLife SafetyRatings: Surface assembliesmeetEN 13501-1 ClassB-s1,d0,ensuringlow flamespreadandminimal smoke toxicity.

4. CavityResonance Optimization:Maximumlow-frequency attenuation (below 250Hz)isachievedbyutilizinganengineeredrear air cavity packed with sound-absorption battinsulation.

 

Standard InstallationProtocol

​​​​​​​To guarantee acousticintegrity and structural compliance,installationmust follow thissequence:

1 SubstratePreparation: Verifybase walllevelness(≤2mm varianceover2m)andapplyacontinuous vaporbarrierfilm.

2 Framework Construction:Erect galvanised steel or treated timber studframingat400mmor600mmcenter-to-center spacings.

3 Acoustic CoreCavityFill:Install32kg/m³ to48kg/m³densitymineral woolinsulationinsidetheframeworkstuds.

4 Panel Attachment: Secure SDPanels acoustic boardsusingconcealedclipsormechanical fasteners,maintaininga1.5mm expansion perimeter.
