Insulation Materials


A Myriad of Choices

In picking the appropriate insulating material for your home project, consider the following factors:

  • What you are insulating
  • The amount of insulation (R-value) you need
  • Installing it yourself or hiring a contractor
  • Budget

We offer two ways to approach your study of materials:   

  • Form of installation
  • Product by product

R-value measures a material's resistance to heat loss.  The higher the R-value of your insulation, the more effective it will be.
