As the first phase of a comprehensive retrofit, the attic was insulated with R-60. A custom super insulated storage platform was constructed as well as a custom airtight hatch . A new bath fan was installed and the kitchen hood-vent was ducted to the exterior. This project was done as part of a WMECO Mass Save pilot program so parts of it qualified for Mass Save rebates and the Heat Loan (0% financing)
When we got there, there was no insulation in the attic. Soffits are unvented and easily accessible to properly seal.
A first step in attic prep is sealing and insulating the soffits with closed cell spray foam. Soffits are responsible for airleakage and the tight angle limits the amount of cellulose that can fit here. Before sealing the soffit, it was confirmed that there was adequate ventilation already in place.
Before- a very normal looking leaky stair access
After- a custom, pully-wheel counter weighted insulated hatch door. With the blower door running, it was confirmed that the hatch was airtight.
R-60 cellulose, insulated platform, very nice work. While the flat was done, some wall cavities were accessed , fiberglass removed and walls properly densepacked. The final blower door = 900CFM50
