Acoustic GuidelinesAcoustic Guidelines.Montage is a flexible,stackable furniture systemthat can provide moderatelevels of acoustical privacyif applied appropriately.Floor-to-ceilinginstallations providevisual and acousticalprivacy. Blocking sound isthe goal of floor-to-ceilingapplications. Higher STCratings are desired.Recommendation: Useglass where possible; nextbest are any other hard tilesurfaces such as steel,fabric over steel, and wood.Where tackability is required,use high-performanceacoustical tiles; all other tilesshould be hard surface.Tip: Do NOT use tackableacoustical tiles in floor-toceilingapplications.Floor-to-ceilingjunctions, floor and ceilinginterface are shipped withfiller insulation for fieldinstallation. Additional lightseals (24) will ship with each9' section of ceiling interface,to improve sound absorption.For additional light seals,reference part numberZ700100SR in the CSS(or CSP Canada) electronicparts catalog.Open plan installationsprovide visual privacy withmoderate levels of acousticalprivacy. Sound absorptionis the goal of open installationplans. Higher-performingNRC ratings are desired..Steelcase’s expanding portfolio of demountable and reconfigurable floor-to-ceiling wallsoffers customers exceptional acoustical and reconfigurable performance, far exceedingthe capabilities of any stackable panel system. Beginning October 2000, Steelcase willno longer offer Montage as a floor-to-ceiling product for new customers, and ceiling interfaceorders will be accepted only for customers who have previously purchased them.ChecklistChecklist30"65".Floor-to-ceiling1Ensure frames arecorrectly double boltedand level.2Ensure junctions, ceiling andfloor interface have fillerinsulation.3Ceiling and floor interface areinstalled without light/soundleaks.4All tile segments have fourlight seals.5Hard tile surfaces are usedwherever possible. At aminimum, one side of theframe must be hard surface.6Sound masking is applied inthe environment.7Ceiling tile has NRC of .70 forsound absorption.For optimum acousticalperformanceFor all installations:1Use steel or other hard tilesurfaces at the frame base.2Use high-performanceacoustical, slatwall, ormarkerboard functional tilesabove worksurface.3Use steel or other hard tilesurfaces at the top of frame.Example:30"WNon-Tackable30"WHigh-PerformanceAcoustical30"WNon-Tackable.MontageTransitional Specification Guide 109
