This beautiful log home was manufactured by 1867 Confederation Log Homes. The house was very large with high ceilings on all floors and cathedral ceilings on the top floor. The project was constructed by the owner. The unique shape of the manufactured logs, and the anchoring system made the building envelope quite airtight to start. This was combined with the owner/builder’s decision to use spray foam insulation in the ceilings and the exterior walls.
The house started with an impressive 1.45 ACH. After approximately 4.5 hours of sealing, we had reduced the air leakage by 65.1%, to an even more impressive 0.51 ACH. Given the size of over 3600 ft2, this would make a significant difference in the comfort level of the house. The location was on the water and the wind was blowing continuously during the seal – the effects of the wind can be seen in the sealing curve by how choppy the curve is.
