However, the E84 test apparatus has changed littleover this period. Slightly different flame spread indices, usually lower, result when recent E84 flame spread calculation techniques are applied to older wood productdata. These changes in flame spread indices are not sufficient to change the flame spread class for the wood products described in this report.3 Sources:APA – APA-The Engineered Wood Association, Research Reports 128, Revised, August 1979.APA2 – APA-The Engineered Wood Association Test Results.CWC – Fire Safety Design in Buildings, Canadian Wood Council, 1996.

WoodWorks Grillehas an NRC value of 0.75 when installedwith a BioAcoustic infill panel.NRC is important in any closed space where reverberation time and noiselevels are an issue: Closed offices, conference roomsMixed plan officeLobby, reception, and work areas Classrooms/core learning areas, gymnasiums, cafeterias Retail spaces; checkout and other customer contact areasFactors that may affect the installed acoustical performance relativeto the published results are: Size of area Number of panels Layout of panels Suspension distance below exposed deck or finished ceilingCeilingExposedStructure(No Ceiling)Ultima(100% Ceiling)WOODWORKSGrille(100% Ceiling)Reverberation Time(RT)3.4 seconds0.5 seconds0.5 secondsRTImprovementN/A85%85%Background NoiseReductionin Decibels (dB)N/A4.7dB5.8dB* You can calculate the acoustical difference that WoodWorks Grille panels can make inyour space by using our online Reverb Calculator Tool at armstrong.com/reverbtool3
