Insulation creates a thermal barrier that keeps heat inside your home during the winter and blocks heat out during the summer. Many homes in Pennsylvania are under-insulated. How does yours measure up?
Benefits of Proper Insulation
Reduce overall home energy consumption
Reduce heating and cooling costs by 15%
Stabilize indoor temperatures year-round
Prevent ice dams from forming on the roof
Reduce noise levels coming from outside
The effectiveness of insulation is measured by its R-value. The higher the R-value, the higher the thermal resistance.
Recommended Insulation Levels
*These recommendations are based on climate zone 5.
2x4 Walls: R13–R15
2x6 Walls: R19–R21
Basement Walls: R11–R19
What Proper Insulation Looks Like
Insulation in the attic shouldn’t just come to the top of the joist; it should completely cover the joists.
R15–R21: Add more insulation
R38–R49: Probably enough insulation
