What Is Insulation R-Value?
The R-value measures an insulation material’s resistance to heat flow. A higher R-value indicates better thermal performance. Different insulation types — fiberglass, spray foam, cellulose, etc. — offer various R-values, allowing customization based on your home’s needs.
While higher R-values provide greater efficiency, not every Portland home requires maximum R-value levels. Factors such as existing insulation, HVAC system efficiency and specific areas needing insulation should all be considered.
Portland’s R-Value Recommendations by Zone
Portland, located in Zone 4, has specific recommendations:
- Attic insulation R-Value: R-38 to R-60 for optimal performance
- Floor insulation R-Value: R-25 to R-30 to prevent heat loss from below
- Wall insulation R-Value: R-13 to R-21 for maximum comfort
These values ensure your home maintains energy efficiency while meeting regional requirements. If your attic already contains insulation, an upgrade may not always be necessary. Our experts evaluate existing insulation to determine whether additional layers or higher R-values are needed, saving you unnecessary costs. Understanding the R-value zone map can make a significant difference in selecting the right insulation.
Calculating Insulation R-Value
R-value is calculated by measuring how well an insulation material resists heat flow across its thickness. This measurement is based on the insulation’s material type and density. Several factors influence the ideal R-value for your home, including:
- Size and layout of your home: Larger homes may require different insulation strategies.
- Areas needing insulation: Attics, walls, basements and crawl spaces have unique requirements.
- Existing insulation: Homes with some insulation may only need spot upgrades.
- Local climate: Portland’s wet winters and mild summers call for region-specific solutions.
