  • How to Install Insulation in Your Attic

    We know. Insulating your attic probably comes somewhere below cleaning gutters or washing windows on the list of things you’d like to do. But the good news is, it’s a lot easier than you think when you use Greenfiber blow-in cellulose. This video will provide you with helpful tips on what you will need to get started and then walk you through the steps on how to insulate your attic.

  • How to Calculate Your Insulation Needs

    R-value is a measure of resistance to heat flow through a given thickness of material. While R-Value is one way of comparing insulations — the higher the R-Value, the better the insulation performance, it is just one of the factors that determine how an insulation product will perform in the real world. Understanding the R-value that you want to reach is an important step in determining how to properly insulate your home. It will also determine the number of bags that you will need for your project.
