SynC · Topic
These are the standards in the SynC Standards library that cover IECC. 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.
Continuous air barrier systems for the above-grade exterior wall enclosure of commercial, institutional, and multifamily buildings, where the objective is to control unintended air movement across the enclosure. Covers the primary air barrier material on the wall field (fluid-applied membranes, self-adhered sheet membranes, mechanically-fastened sheets, integrated and board sheathing with sealed joints, and closed-cell spray polyurethane foam used as an air barrier), the accessories and transition materials that carry the air barrier plane across changes of material and plane, the tie-ins to the roof, below-grade waterproofing, and fenestration, substrate preparation and priming, the exposure window before cover-up, and the field verification that proves the installed plane is continuous — field adhesion testing, air leakage site detection, and whole-building air leakage testing.
Thermal insulation installed in the opaque building envelope of commercial, institutional, multifamily, and residential buildings, covering above-grade wall cavity and continuous insulation, low-slope and steep-slope roof and attic insulation, floors and ceilings over unconditioned space, crawl space enclosures, below-grade foundation walls, and under-slab and slab-edge insulation. Covers all principal insulation forms sold in the North American market: mineral fiber batt, blanket, and board; loose-fill and dense-packed cellulose, fiberglass, and mineral wool; extruded, expanded, and graphite-enhanced polystyrene board; polyisocyanurate board; cellular glass; wood fiber and cellulosic board; spray-applied polyurethane foam; and reflective insulation and radiant barriers. Also covers the thermal resistance basis used to demonstrate energy code compliance, surface burning and foam plastic fire requirements, vapor retarder classification and placement, air barrier coordination, thermal bridge mitigation, and field verification before assemblies are concealed.
