Final answer:
The correct answer is insulating material, which is used for acoustical and fireproofing purposes and includes binders that impart durability and flexibility. Fiberglass batt is a common example of such an insulating material used in buildings.
Step-by-step explanation:
Material that is sprayed, troweled, or otherwise applied for acoustical, fireproofing, or other purposes is called insulating material. Options such as adhesive substance, coating compound, and sealing agent may also be applicable in certain contexts, but when it comes to applications specifically for acoustical and fireproofing functions, insulating materials like fiberglass batt are most commonly used. They help in preventing heat transfer between the inside of a building and the outside environment. Insulating materials can also incorporate binders like acrylics or polyurethanes, which give them properties such as durability, flexibility, and toughness. These properties are essential because they ensure that the insulating material adheres well to surfaces and performs its intended function effectively. An example of an insulating material is the fiberglass batt, as shown in Figure 1.23, which is commonly used in walls and ceilings.
