SynC · Topic
These are the standards in the SynC Standards library that cover Curtain Wall. 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.
Structural cold-formed steel framing designed under AISI S100 and AISI S240 and, where the framing participates in a seismic force-resisting system, AISI S400. Covers load-bearing stud walls, exterior non-load-bearing wind-bearing wall framing in both infill and bypass arrangements, cold-formed steel floor joists, roof rafters, and trusses, cold-formed steel shear walls and braced walls, and the parapet, canopy, and soffit framing that carries calculated load. Addresses the division of design responsibility between the Engineer of Record and the specialty engineer, sheet steel and metallic coating selection, member designation and identification, out-of-plane deflection criteria, movement accommodation at the head of wall, bridging and bracing, screwed, welded, powder-actuated, clinched, and bolted connections, opening and built-up member framing, web penetrations and field modification, erection tolerances, listed fire-resistance-rated assemblies, and field inspection.
Architectural vision glass and glazing for storefronts, curtain walls, windows, exterior and interior doors, sidelights, transoms, borrowed lites, partitions, and other building glazing infill. Covers annealed, heat-strengthened, and fully tempered flat glass; laminated glass; coated (low-emissivity and solar-control) glass; insulating glass units (IGUs) including double and triple makeups; spandrel and ceramic-frit glass; safety glazing in hazardous locations per the International Building Code; glass strength and thickness determination under wind and snow load per ASTM E1300; thermal stress and edge-condition selection of annealed versus heat-strengthened versus fully tempered glass; nickel-sulfide heat-soak treatment for tempered glass; low-iron glass; warm-edge spacers and inert-gas fill; structural silicone and dry-gasket glazing methods; setting blocks, edge clearances, and glazing accessories; and field installation, testing, cleaning, and warranty of the glass and glazing materials.
Aluminum-framed glazed curtain wall acting as the primary non-load-bearing exterior enclosure of a building — stick-built, semi-unitized, and unitized systems that span vertically across one or more stories and hang from the building frame at discrete anchors. Covers the assembly method, the water management principle and internal drainage, mechanically captured and structurally silicone-glazed retention, framing member sizing and thermal barriers, the vision and spandrel glazing selection tree the framing delivers, aluminum finishes, air and water penetration resistance, thermal transmittance and condensation resistance, acoustic performance, wind pressure and deflection criteria, thermal and seismic movement accommodation, wind-borne debris impact resistance, perimeter fire containment at the floor edge, anchorage and movement joints, perimeter air and water barrier continuity, fabrication, mockups, erection, and field water and air testing.
