What temperature should gypsum ducts not exceed?

Gypsum ducts are designed to handle specific temperature limits to maintain their structural integrity and performance. The proper maximum temperature for gypsum ducts is crucial for avoiding any potential damage that could compromise the HVAC system's efficiency and safety.

The correct answer, which states that the maximum temperature should not exceed 125°F, is in line with the guidelines set forth for gypsum-based ducting materials. Exceeding this temperature can lead to degradation of the duct material, including issues such as warping, cracking, or reduced insulating properties, which would negatively impact the system's airflow and efficiency.

This temperature limit is particularly relevant in environments where heating elements or high temperatures are involved, as it helps to ensure that the materials used in HVAC systems will function effectively and safely without compromising their integrity. Understanding this limit is essential for ensuring compliance with building codes and maintaining a reliable heating and cooling system.
