Energy saving tips
Tips to reduce heat loss and electric costs.
Air infiltration is the largest proponent of heat loss in a home. By reducing heat loss through sealing windows, doors, and high R-values in the envelope of a home, we can reduce our heating needs while providing more comfort.
| Surface area: | Minimum insulation | Preferred |
| Walls: | R11 | R19-R40 |
| Ceiling: | R30 | R38-R70 |
| Floors: | R30 | R30 and or Taped Reflectix |
| Windows: | R2 (thermopane) | R3 (low E) or (R4-R7) |
- Provide vapor, an air infiltration barrier, and gasket or caulk sealant to minimize air infiltration.
- Use tight thermopane, wood, or thermal break metal windows and restrict glass area percentage to 15% of total floor space, with the largest windows facing south.
- Minimize ceiling and roof openings.
- Insulate floors using Reflextix floors, especially above unheated spaces such as basements.
