SynC · Topic
These are the standards in the SynC Standards library that cover Ceilings. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Gypsum board partitions, wall assemblies, and ceiling systems for commercial, institutional, and multi-family residential buildings. Covers interior non-load-bearing steel-framed partitions, shaft walls, chase walls, area separation walls, furring and freestanding wall assemblies, and suspended or directly attached gypsum board ceiling systems. Includes fire-resistance-rated and sound-rated assemblies, all board types, steel framing and furring, finish levels, joint treatment, accessories, and control joints.
Room-side air distribution devices that terminate a ducted or plenum air system at the boundary of an occupied space - supply outlets (square and rectangular face, round face, linear slot, swirl, displacement, light-fixture-integrated), return and exhaust inlets, and transfer openings, together with the frames, cores, integral dampers, and finishes furnished as part of the device. Covers the performance criteria that govern occupant comfort and acoustic acceptability (throw at 50, 100, and 150 fpm terminal velocities, ADPI, occupied-zone air speed, occupied-space sound level), device materials for dry, wet, and corrosive service, exposed finishes, security and anti-ligature construction, installation and support, and field balancing and verification. Applies to new construction and to renovation where devices are connected to a distribution system.
Field-applied surface preparation, primers, and finish coatings on interior architectural substrates — gypsum board, plaster and veneer plaster, concrete, concrete masonry, ferrous and galvanized metal, and interior wood — in commercial, institutional, and multi-family residential buildings. Covers latex, alkyd, and water-based epoxy paint systems applied to walls, ceilings, doors and frames, exposed structure, and exposed mechanical and electrical work that is to be field-painted.
Direct-hung metal suspension grid systems and acoustical panels or tiles — both exposed-tee lay-in and concealed-spline — for commercial, institutional, healthcare, educational, and hospitality interiors. Covers the suspension grid (type, profile, duty classification, and finish), acoustical panels (material, size, edge detail, and surface texture), acoustical performance (NRC and CAC), light reflectance, surface-burning fire performance, fire-resistance-rated ceiling membrane assemblies, seismic restraint and perimeter treatment, hold-down clips, trim and moldings, hanger wire and bracing, and integration with light fixtures, air devices, and sprinkler heads.
