Final answer:
Unfaced fiberglass batt insulation is not typically used for fireblocking.
Step-by-step explanation:
Unfaced fiberglass batt insulation is not typically used for fireblocking.
Fireblocking involves the use of specific materials or construction techniques to prevent the spread of fire through concealed spaces within a building. Unfaced fiberglass batt insulation is primarily used for thermal insulation, not for fire protection.
For fireblocking purposes, different materials such as fire-resistant foam or mineral wool are typically used to fill gaps or openings in walls, ceilings, or floors. These materials have a higher fire resistance rating compared to unfaced fiberglass batt insulation.
