Why Should I Add Insulation?

The leading cause of energy loss in a home is inadequate insulation.  Adding insulation to your attic or walls will help keep your home cool in the summer and warm in the winter.  You will save money on your utilities and your home will be more comfortable with an even temperature throughout the house.

How Much Insulation Do I Need?

The amount of insulation needed is determined by the type of R-value insulation you use.  For loose fiber insulation such as cellulose, multiply the R-value of your insulation by 3.7 to get the depth in inches needed.  For fiberglass insulation multiply the R-value of your insulation by 3.2 to get the depth needed.

What Type of Insulation Do I Need?

The climate in Denver varies drastically!  One day it could be 70 and sunny and the next day 20 degrees.  The US Department of Energy has set a recommended R-value for different climates and heat source.  Denver requires a higher R-value than an area that does not share our cold weather such as Phoenix or San Diego.

If you live in Colorado and you use electric heat, it is recommended you use R-49 in your attic, R-22 in your walls, R-19 in your basement and R-25 in your floors.

If you use natural gas to heat your home, it is recommended you use R-49 in your attic, R-18 in your walls, R-11 in your basement and R-25 in your floors.

What does the R-value of Insulation Mean?

Home insulation is identified and rated based on it’s ‘R-value‘. The R stands for resistance to heat flow.  This means the higher ‘R-value’ insulation has, the greater effect it will have against heat transfer.
