What is a critical step in the installation of rigid board insulation regarding daily work practices?

A critical step in the installation of rigid board insulation is to ensure that it is covered at the end of each workday. This practice is essential for protecting the insulation material from environmental factors such as moisture, debris, and UV exposure, which can compromise its structural integrity and insulation efficiency. Covering the insulation helps to maintain its thermal performance and overall longevity, making it a vital aspect of daily work practices in roofing and insulation installation. Additionally, protecting the materials helps to ensure compliance with building codes and standards, which are designed to ensure quality and safety in construction projects. This careful attention to covering the insulation reinforces the idea that proper installation practices lead to better performance and durability of roofing systems.
