HEM White Sage Incense Sticks, 100-Count
Airflow visualization and draft mapping tool
The low-cost diagnostic tool for mapping active air infiltration points before any sealing material is deployed. The slow, consistent smoke stream reacts visibly to even minor pressure differentials, bending sharply toward or away from any active breach point in the building envelope. 100 sticks provides more than enough supply to complete a full room-by-room audit of an entire property.
