In insulation work, what does finishing refer to?

• A. Application of protective coating over insulation
• B. Installing insulation
• C. Cutting insulation
• D. Securing insulation to the structure

Answer: (A)

Finishing refers to applying a protective coating or outer layer over the insulated surface. This final layer seals and protects the insulation from moisture, weather, physical damage, and UV exposure, helping the system last longer and sometimes providing a surface ready for paints or coverings. The other actions—installing, cutting, and securing—are steps to put the insulation in place; finishing comes after to shield and complete the job.
