Energy Measures Are All In Place
After taking most of this 100 plus year old house to the studs, the energy efficiency measures were all in place. That includes Triple-pane windows (by Kohltech), air sealing throughout the house, blown-in cellulose insulation in attic with R-80 and in walls with R-18, 15 mil heavy-duty polyurethane liners lined the crawlspace and basement. (Yes, […]
Attic Sealing and Insulation
The attic covers only part of the house. To insulate it, Tom’s crew placed 20 inches ( ) of loose fill cellulose. Blower door tests and infrared camera shots showed that the access to the attic was still leaky. They quickly placed two layers of foam board to close the access off and foam sealed […]
First Floor and Second Floor Demolition
Tom has begun taking interior walls down and getting ready for air sealing, insulation and relocation of rooms, stairways and bathrooms. These pictures give some perspective of what is happening. Coming next: Attic Demolition See also: Partnering With Green Hearted Companies and the entire From Foreclosure To Green Home series. This forum provides you with […]
Energy Improvement Opportunities
This is a 100+ year old house. Obviously there are many energy efficiency shortcomings (hence many improvement opportunities). The house has been vacant for over 2 years so we don’t have the latest operational information. Exterior Walls. Before taking the walls apart, we already expect little to no insulations for houses of this age. The […]
The Terry Project: Cellulose Insulation and Energy Modeling
The latest work done on Cathy’s house is the application of insulation. They have decided to use blown cellulose to fill the exterior walls and the cathedral ceiling. The cellulose insulation is expected to yield R-13 for the walls and R-38 for the ceiling. The
The Terry Project: Air Sealing, Insulation, Windows
The family room with a vaulted ceiling requires particular attention for insulation. The roof sheathing material is foil faced oriented strand boards (OSB). The foils act as a radiant barrier which will cut down the heat from the hot roof from getting into the living space. Under the radiant barriers, sheet rocks were installed leaving […]
A Deep Energy Retrofit Project
Staying in this house was never in the plan. We’d hoped to move into this little house in town for a couple of years, remodel and flip it, and then move to the country to live “off the grid.” But then it happened. We fell in love. Not only with our “little blue house,” but […]
Comparison Of Insulation Materials
Homes should be well insulated in the attics, walls and underfloors to avoid heat loss in winter and to keep heat out in summer. The effectiveness of insulation material is measured in R value. The higher the R value, the more effective it is. Building codes in most mild climate jurisdictions require attic insulation to […]
