About Insulation

Control the climate inside your home with the right insulation. Beyond attics and walls, imagine a home insulation solution that creates a snug “housing envelope” controlling heat, air, moisture and sound. Don’t forget garage door insulation, as well as other overlooked potential spots to control your indoor environment. Even the smallest gaps and cracks can be filled with spray-on insulation

What is the R-Value in insulation?

It’s simple. The higher the R-Value, the greater its effectiveness. If you live in a warm climate, you require a lower R-value. Cold areas require a higher R-Value, like an R- 49. Increase your R-value by layering insulation. Layer more insulation over the old for more effectiveness.

Insulation Materials Explained

The format of house insulation you need depends on where you put it and if you need to control moisture. Keep your space dry with faced insulation. It uses a sheet of paper to control moisture vapor between walls and floors. Unfaced installation doesn’t have a paper moisture shield. It’s often used over existing insulation in the attic, where moisture control isn’t needed. 


Try a spray foam insulation kit to fill cavities, gaps, cracks, expansion joints and other sources of air leaks. It helps resist moisture that can lead to mold or mildew and provides increased sound and thermal insulation.

Rolls, batts or blown-in insulation

Rolls are easy to transport and can be cut to the length you need. Use these to cover large areas. Batts come in pre-cut lengths, which makes installation fast and easy, especially for framed spaces. These insulation panels also provide excellent noise control. Tip: Batt insulation packages contain more square feet than rolls. Blown-In insulation is installed using blowing machines. It makes adding insulation to your attic a breeze.
