SynC · Topic
These are the standards in the SynC Standards library that cover Firestopping. 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.
Through-penetration firestop systems and fire-resistive joint systems installed in fire-resistance-rated walls, floors, floor-ceiling assemblies, roof-ceiling assemblies, and smoke barriers in commercial, institutional, healthcare, and multi-family construction. Covers tested and listed systems for mechanical, electrical, plumbing, and communications penetrations, head-of-wall and bottom-of-wall joints, wall-to-wall joints, floor-to-floor joints, and floor-to-wall joints. Includes sealants, intumescent and endothermic products, mortars, mineral wool packing, collars, wrap strips, putty pads, composite sheets, and pillow systems. Addresses F, T, L, and W ratings; joint movement classes; identification labeling; installer qualification; field inspection per ASTM E2174 and ASTM E2393.
Stationary exterior and interior louvers and the full range of air-control and life-safety dampers in commercial, institutional, and light-industrial buildings. Covers drainable-blade, storm-resistant (wind-driven-rain), sand-trap, acoustic, combination louver/damper, and penthouse/gooseneck louvers selected by free area and water-penetration class at the design intake velocity; air-control dampers (parallel- and opposed-blade) selected by AMCA 500-D leakage class; backdraft, gravity, and pressure-relief dampers; and the life-safety dampers required at rated barriers — fire dampers (UL 555), smoke dampers (UL 555S), combination fire/smoke dampers, and ceiling radiation dampers (UL 555C) — together with actuators, fusible and resettable links, sleeves, retaining angles, access, and the firestopping interface. Includes hurricane-zone (AMCA 540 / 550) and Florida/High-Velocity-Hurricane-Zone louver requirements and the AMCA Certified Ratings Program basis for ratings.
