What is the maximum temperature for faced flexible fiberglass insulation (temp wrap)?

Faced flexible fiberglass insulation, often referred to as temp wrap, is designed to provide thermal insulation in various applications. The maximum temperature rating for this type of insulation is 250°F. This rating means that the material can effectively insulate and maintain its structural integrity at temperatures up to this limit without degradation, which is crucial for ensuring safety and performance in environments where heat is present.

At temperatures above this threshold, the integrity of the insulation can be compromised, leading to a decrease in insulation effectiveness and potential hazards. The correct temperature is based on the material's ability to resist heat transfer while remaining stable under prolonged exposure to heat. The temperature rating is established through testing and adherence to industry standards, ensuring that users can rely on the insulation for safe and effective operation at designated temperatures.

The other temperature choices exceed this important threshold, which would not be suitable for flexible fiberglass insulation due to the risks of material breakdown and inefficacy in thermal insulation.
