Which of the following insulating materials is specifically designed for high-temperature applications?

Fiberglass wrap is specifically designed for high-temperature applications due to its ability to withstand elevated temperatures without losing its structural integrity or insulation properties. It is made from fine glass strands that can endure heat exposure while providing effective thermal insulation. This makes fiberglass wrap suitable for use in places like industrial settings, around pipes, and in HVAC systems where heat resistance is crucial.

In contrast, options such as foam insulation and cellulose insulation are generally more suited for standard insulation applications, where high-temperature resistance is not a primary requirement. Foam insulation can deform or degrade under high heat, while cellulose insulation is made from recycled paper and can combust under extreme conditions, making them less than ideal for high-temperature scenarios. Mineral wool insulation does offer good fire resistance and can handle higher temperatures than some other materials, but it is primarily used for soundproofing and fire safety rather than intentionally designed for high-temperature applications, so fiberglass wrap remains the superior choice in this context.
