What is the function of a thermal barrier?

The function of a thermal barrier is to limit the average temperature rise of unexposed services. This is particularly important in fire protection systems, where a thermal barrier is designed to slow down the transfer of heat. By doing so, it helps to protect adjacent structures, pipes, and wiring from the damaging effects of high temperatures during a fire. This function is critical for maintaining the integrity of a building’s overall safety features and ensuring that other systems are not compromised by excessive heat.

This focus on temperature regulation is crucial in fire safety, as it helps maintain operational functionality of firefighting systems and prevents the spread of flames and heat throughout a structure. The use of thermal barriers ensures that essential components of the fire protection system remain effective and reliable under fire exposure conditions.
