About This Project
Insulating the attic, walls and basement of this old, Maine home made an immediate impact on the homeowners’ comfort and fuel usage
The Koneff family relocated to Maine from Maryland in December 2010 and found the perfect home for them. The 100+ year old home was a typical old, Maine structure and lacked insulation. The Koneffs loved their home but found it was too cold for comfort and extremely drafty. They were also having oil and LP tanks filled every 3 weeks during the winter. The family learned of Penobscot Home Performance through the Efficiency Maine website and immediately set up an energy audit.
Home Improvements
- Air sealed throughout the home reducing drafts by 56%
- Insulated attic and exterior walls with dense-packed cellulose increasing the R-Value of the home from R-5 in the attic and R-13 in the walls to R-60 and R-15
- Insulated basement with 2″ of closed-cell spray foam, a product which stops air infiltration and insulates to R-13
- Benefits
- The family noticed “an immediate improvement in comfort!” after completing the project with PHP
- Air leakage has been reduced by 56% resulting in immediate comfort improvements and less frequent calls to the fuel companies
