What’s Your R-Value?

 

Efficiency in the 3 R’s – Reading, ‘Riting and ‘Rythmatic – will get you good grades. Efficiency in a different R – R-Value – will get you a good electric bill. In insulation, you want a high R-Value.

 

Insulation is a barrier that keeps the outside temperature from changing the inside temperature of your home. What is R-Value? The R-Value rates the insulation’s resistance to heat flow. With about 50 percent of your utility bill going towards heating and cooling your home, a higher R-Value in your insulation translates into a lower utility bill for you. Insulation gives an added bonus by dampening sound and making your house quieter.

 

For most of Florida, attics should have insulation rated from R30 to R60 and wall insulation rated R13 to R15.  Check the R-Value when you purchase insulation material to make sure you are getting the thickness that your home needs.

 

Some insulation questions you should ask about your home:

 

1. What is the R-Value of insulation in the attic floor or top floor ceiling? 

  • If you have three inches or less of insulation, you probably need to add more insulation to reach the minimum recommended level.  Many utilities offer rebates for homeowners making large insulation investments.

 

2. Are the walls and crawl spaces insulated? If so, to what R-Value?

  • Add insulation in between any heated/cooled space and any unheated/uncooled space.

 

3. Is the insulation installed properly?

  • Insulation with gaps or compression will not perform at its best R-Value efficiency.

 

4. Has my house had an energy audit recently?

 

To find what may work best for your house, consult an insulation professional in your area. Check to see if tax rebates or other incentives are offered for your insulation project.
