Anchorage has a distinctly cold seasonal pattern. National Weather Service climate data uses 1991–2020 normals for the area; January normally has an average maximum temperature of about 22.7°F and an average minimum of 11.0°F. That extended cold period means building assemblies need to be considered carefully when property owners are addressing insulation and heat transfer. National Weather Service Anchorage climate data
Local housing demand also spans a substantial existing building base. The U.S. Census Bureau reports 121,429 housing units in Anchorage Municipality as of July 1, 2025, with 63.9% of occupied housing units owner-occupied during 2020–2024. For homeowners and builders, insulation decisions therefore vary between existing homes, renovations, and new construction. Spray foam can be evaluated as part of those projects based on the building assembly, accessible areas, and project requirements. U.S. Census Bureau Anchorage QuickFacts

Yes, spray foam can be incorporated into appropriate areas during new construction when the building design and planned assembly support its use.
Commercial properties can have different insulation requirements based on their use, construction, size, and assemblies, so the appropriate approach should be evaluated for each project.
