How Attic Design Affects Moisture Control

Attic design plays a central role in roof moisture behavior by influencing airflow paths, temperature stability, and drying potential within the roof assembly.

RNKC Definition

RNKC defines attic design as the spatial and structural configuration that determines how air, heat, and moisture move between living space and roof components.

Design Factors That Influence Moisture

• Ventilated versus unventilated attics
• Insulation placement and continuity
• Air barrier effectiveness

RNKC Perspective

RNKC emphasizes that attic design must be evaluated as part of the overall building envelope rather than as an isolated roof feature.
