Can aluminum strips be used for building insulation?

Aluminum strips are not typically used for building insulation. Insulation materials are designed to resist heat flow, and aluminum is a good conductor of heat, which means it would not effectively insulate a building. Common insulation materials include fiberglass, cellulose, and foam, which are poor conductors of heat and can effectively reduce heat transfer. Aluminum strips might be used in construction for other purposes, such as reinforcement or as part of a vapor barrier, but not for their insulating properties.
