How should the required insulation shield be secured?

The correct answer emphasizes the importance of securing the insulation shield effectively to prevent displacement. In mechanical systems, insulation shields are crucial for maintaining temperature regulation and preventing heat loss or gain, which can affect energy efficiency and system performance.

When insulation shields are not properly secured, they can shift or move due to airflow, vibration, or other mechanical stresses. This could lead to sections of the system becoming unprotected, resulting in inefficiencies or even damage. Therefore, securing the insulation shield to prevent displacement is essential in ensuring the integrity and effectiveness of the insulation.

Other options may suggest methods such as using adhesive, screws, or even placing weights on the shields, but these do not address the core requirement of minimizing movement. While those methods may have their applications in certain scenarios, the primary goal remains ensuring the insulation remains in its designated position throughout its service life. Properly preventing displacement addresses performance, safety, and compliance with mechanical code requirements.
