What is an important consideration when installing insulation in varying temperatures?

When installing insulation in environments with varying temperatures, it is crucial to select materials that can withstand thermal expansion. As temperatures fluctuate, materials expand and contract, which can cause stress and damage if the insulation is not designed to accommodate these changes. By choosing appropriate insulation materials that are flexible and can manage the effects of thermal expansion, you help ensure the longevity and effectiveness of the insulation system. This consideration is essential for maintaining energy efficiency and preventing potential issues such as gaps, cracks, or overall system failure over time.

Other options might suggest focusing on factors that are either non-essential or irrelevant to the performance of insulation in varying temperatures, which could lead to ineffective insulation installation.
