What a lesson this project was. More so about human dynamics, but the retrofit was varied and challenging.
The main house is a historic 17th century post and beam structure. The carriage house is a converted barn. Both houses suffered from ice damming and comfort issues.
A Colonial beauty with many thermal boundary issues
- Ductwork in the attic was encapsulated with close cell spray foam to improve distribution efficiency. R-60 cellulose was added to the attic flat
The large beams in the attic flat were sealed with closed cell spray foam
The large South facing knee wall rafter cavities were expanded with new lumber. This enabled optimal insulation performance in the cavities of closed cell foam and denspacked cellulose.
Carriage house roof slope that had ice damming. The closed slopes and knee wall attic space were treated
Who says a Director of Operation, doesn't get dirty?! (your's trully in action) Foil faced rigid foam board added, seams air sealed.
A fan box in a tight eave can contribute to ice damming. This one is airsealed. The rafter slopes, empty in the pic, will get densepacked with cellulose
After the Carriage House attic is airsealed, R60+ cellulose insulation is added.
