This home achieved amazing 50% air-leakage reduction. 4,000CFM50- 2,000CFM50
The work-scope included a complete attic retrofit, the dense packing of walls, dormer bump-out details and other detailed airsealing and insulation.
The majority of the air-leakage reduction came from densepacking the hollow walls.
The project received $2,500 of incentive money from the utility company.

Exterior walls ready to be blown.
Come back soon to see the before and after infrared images of this project
