What is the purpose of legible identification on duct insulation?

Legible identification on duct insulation serves the essential purpose of informing about specifications. When insulation on ducts is clearly labeled, it communicates critical information regarding the type of insulation used, its thickness, thermal resistance (R-value), and any relevant codes or standards it meets. This information is vital for ensuring that the insulation is compliant with building codes and is appropriate for the specific application it is being used in, thus facilitating proper installation and maintenance.

This identification helps contractors and inspectors assess whether the insulation meets the required performance criteria and thermal efficiency. By having clear labels, it aids in the selection of compatible materials and ensures uniformity in the installation process, leading to optimal system performance and energy efficiency over time.
