Before committing to the project, Dave came to the house and after inspecting the attic and the roof, we had a very fruitful discussion about the pros and cons of the different possible insulation options. My house is a 4000 square foot twenty-year old colonial with questionable insulation. Like many houses, my attic gets very cold in the winter and very hot in the summer, and with second floor ductwork in this space, I was hoping to not only stop general home heat loss, but also operate the furnace and the air conditioner more efficiently. We discussed the common practice of air-sealing the floor of the attic, but we ultimately went with the hot roof option to bring the attic into the "envelope" and make it a conditioned space. He explained that the soffit and ridge vents would be sealed since such a conditioned space would need neither the heat nor the moisture dissipating properties of such vents. He explained that a a fire and mold resistant cellulose fiber would be dense-packed to a depth greater than the width of the roofing joists to offset the poor insulating properties of wooden structural members. In addition to insulating the underside of the roof, the ends of the main section of the house (gables) would also be insulated.Dave also mentioned that a few recessed lights in three bedrooms would need to be replaced with LED units to allow for more effective placement of the cellulose. Although the primary goal was not sealing the house, blower door tests would be performed before and after the work to measure any improvements. The crew of 4-5 people spent about six days prepping the attic space and packing the insulation. I felt very comfortable with the crew moving in and out of the house, and they were quite conscious about cleaning up. Since most traffic occurred via a ladder to the attic, they did not need to be regularly moving through the two floors of living space. The crew seemed to work diligently, and were friendly and willing to entertain my numerous questions. I am very satisfied with the project and will continue to monitor and evaluate and compare past and future energy usage trends. In addition to energy cost savings benefits, I feel that the threat of ice dams and the ensuing damage has been dramatically reduced.
My attic was insulated by blowing and compacting a thick layer of shredded cellulose under my roof to achieve an R-value of approximately 40.
