| New heating system New high-efficiency, sealed-combustion heating system with dual-fuel capabilities allows fuel flexibility, safer operation, and more efficient use of backup fuel. Electric equipment in this heating system operates at 100 percent efficiency and at significantly lower cost than the customer's old gas furnace. |

| Rim joist insulation and air sealing Extruded polystyrene insulation installed in the rim joist area (where the home rests on the foundation) stops cold air from leaking in and keeps heat inside. |
 |
| Basement windows New Vinylite basement windows reduce air infiltration, help hold heat in, and increase comfort. |
 |
| Attic insulation Insulation in the floor area behind knee walls prevents heat loss and nagging, destructive winter ice dams. Williams Construction sealed floor joist cavities to stop warm air from leaking into this attic space. Cellulose insulation on the floor helps hold warm air in the living space below. |

| Roof ventilation The cold side of any insulated surface needs ventilation to avoid moisture buildup that can cause costly structural damage. Williams Construction added roof vents in the home to reduce condensation in the attic area. |
