Ceiling grid types4/1/2024 However, the non-woven acoustic fabric behind the perforations may have to be replaced since grime attached to the fabric is more difficult to remove and may also interfere with noise reduction. Avoid ceiling systems that use PVC in their framing or textiles.These painted metal ceiling panels can be rejuvenated by wiping with a degreasing cleaning agent.Polyvinyl chloride (PVC) contains potentially dangerous chemical additives that may be released during production, use and disposal.Look for products that use a single fiber type.Blended textiles can be difficult, if not impossible, to separate and properly recycle. Textile-based ceiling tiles may contain a blend of fibers, either synthetic, natural or mixed.Avoid these hazards by specifying verified Red List Free or transparent materials, preferably third-party-verified HPDs at 100 ppm. Ceiling systems and spray insulations are a potential source of flame retardants, per- and polyfluoroalkyl treatments (PFAS), antimicrobials and fly ash, which can contain heavy metals, such as cadmium, mercury and arsenic waste.Look for products that use no added urea formaldehyde (NAUF), no added formaldehyde (NAF) or ultra-low-emitting formaldehyde (ULEF) resins.Composite wood products or veneer panels that have composite cores frequently contain adhesives with formaldehyde that may off-gas at concentrations exceeding health-based guidance values. When designing custom ceiling systems, select minimally processed woods and metals that don’t rely on toxic adhesives or coatings.WELL features Additional recommendations: Consider a LEED v4.1 substitution for EQc9 and pursuing the heating and air conditioning (HVAC) background noise and reverberation time options.Look for products with a noise reduction coefficient (NRC) rating of at least 0.90.LEED EQc9 and WELL S03 and S05 are acoustic performance requirements.FSC-certified wood is the only certification LEED recognizes. It’s worth noting that there are other third-party certifications available besides FSC that IBM recognizes.Specifying Forest Stewardship Council (FSC)-certified woods and metals with recycled content for custom ceilings will contribute to LEED credit MRc4 building product disclosure and optimization – sourcing of raw materials.Consider exemplary performance for an innovation point for MRc3.Consider option 1 for MRc3, option 2 for MRc4 and option 1 for MRc5.Consider a LEED v4.1 substitution for EQc2.Points are awarded based on meeting the requirements for applicable criteria and the number of products installed. These documents are called for by LEED credits EQc2, MRc3, MRc4 and MRc5, and WELL features X05, X06, X07 and X08. While IBM does not necessarily endorse a third-party labeling scheme, Declare labels, Health Product Declarations (HPDs), Environmental Product Declarations (EPDs), and volatile organic compound (VOC) testing certifications may contribute to LEED and WELL certification.Sustainability and wellness recommendations LEED and WELL: Drywall can also be considered for primary circulation routes.Ĭore area ceilings fall within the purview of the landlord’s specification. Gypsum ceilings are typically used within restrooms and pantry spaces. Open ceilings should form the bulk of open workplace areas to create a sense of volume and spaciousness. Specialty drop ceiling systems can be used to attenuate noise, but more frequently are used to delineate boundaries or add variation to the ceiling landscape.Īcoustical ceiling tile should be used in enclosed collaboration and enclosed individual spaces throughout the workplace as these spaces require a higher degree of acoustical privacy. These ceiling systems, which include felt or acoustical metal, should be considered in enclosed collaborative spaces tangential to the Welcome and Connect zones, signifying their larger capacity and collaborative nature. Feature ceiling systems, such as wood or perforated metal, should be placed in the the Welcome and Connect zones to delineate their unique functions and create differentiation in the space.
