What is the temperature range that fiberglass batt insulation can withstand?

Fiberglass batt insulation can withstand temperatures in the range of 1000°F. This capability is primarily due to the glass fibers’ composition and structure, which enable them to resist high temperatures without melting or degrading significantly. Fiberglass batt insulation is often used in applications that require heat resistance, such as in attics, walls, and ceilings, where it helps manage thermal performance and energy efficiency while maintaining safety under high heat conditions.

The fact that it can handle up to 1000°F makes it suitable for various building applications, ensuring durability and effectiveness in insulating against heat transfer. Its ability to remain stable at high temperatures is critical in preventing heat-related damage to structures and ensuring the safety of the building’s occupants.
