title: Building Thermal Insulation
…2 unchanged lines
description: >
When to use: Thermal insulation installed within or on the building envelope for commercial, institutional, and residential construction, covering above-grade wall assemblies (cavity and continuous), low-slope and steep-slope roof assemblies, floor and ceiling assemblies over unconditioned space, and below-grade foundation wall and slab-edge assemblies. Applies to all principal insulation types: mineral fiber batt and blanket, rigid extruded polystyrene (XPS), expanded polystyrene (EPS), polyisocyanurate board (polyiso), mineral wool board, and spray-applied polyurethane foam (open-cell and closed-cell). Covers R-value determination and energy code compliance, installation grading, continuous insulation and thermal bridging mitigation, fire and smoke characteristics, vapor retarder and air barrier coordination, and field inspection.
− Not intended for: Pipe and equipment insulation for mechanical systems (see [[sync/hvac-piping-insulation]]); duct wrap and duct liner (see [[sync/hvac-ductwork]]); roofing membrane systems and roof insulation specified as part of a membrane roofing assembly (see [[sync/membrane-roofing]]); below-grade waterproofing and dampproofing insulation specified integral to a waterproofing assembly (see [[sync/below-grade-waterproofing]]); interior gypsum board assemblies with integral insulated framing (see [[sync/gypsum-board-assemblies]]); and sound attenuation batts or acoustical treatment specified solely for acoustic performance rather than thermal performance.
