What does CFM stand for in roofing and construction?

CFM stands for Cubic Feet per Minute, which is a critical measurement in roofing and construction, particularly when discussing ventilation systems and air flow. This unit quantifies the volume of air moved or circulated in one minute. In roofing applications, proper ventilation is essential to maintain temperature control, prevent moisture accumulation, and enhance the lifespan of roofing materials.

Understanding CFM helps in assessing the efficiency of ventilation systems, ensuring that buildings have adequate airflow to avoid issues such as mold growth or inadequate insulation performance. Correctly calculating and implementing CFM measurements contributes to a building's overall energy efficiency and comfort levels.
