Insulating your home is often one of the best ways to make your home more energy-efficient and comfortable all year. When determining how much insulation your home needs, it depends on two factors: the region you live in and the area of your home that needs to be insulated. For Portland homeowners, trust our experts to help you select the best insulation products and services to meet your needs.

What Is Insulation R-Value?

The R in R-value stands for resistance, and it’s a basic measurement of an insulation material’s resistance to heat. Different types, thicknesses and densities of insulation materials will have different R-values, but generally speaking, a higher R-value means better energy-efficiency and climate control for your home.

However, not all homes need the highest level of R-value insulation. If your home has existing insulation or if you live in a warmer climate, a higher-level R-value may be unnecessary.

How Is Insulation R-Value Calculated?

An insulation product’s R-value is calculated by measuring heat flow across a surface where each side is at a particular temperature. More simply, R-value is measured in terms of resistance to heat flow. R-values are measured per inch of thickness, and in general, a high R-value means a good (but often more expensive) insulation material.

Insulation professionals can tell you how much insulation you need based on:

  • What region you live in (see the map below)
  • What type of HVAC systems you have
  • The size of your home
  • Where you need to insulate

What R-Value Is Best for My Portland Home?

Here in the Portland, Oregon, area, we’re in Zone 4. That means the ideal attic insulation R-value is between R-38 and R-60, while floor insulation should range between R-25 and R-30.

However, if your attic has existing insulation, you may not need as high of an R-value. It’s best to discuss your home’s specific needs with one of our insulation experts to ensure that your needs are met.
