Do I Need More Attic Insulation?

attic insulationHow To Know When You Need More Insulation

The best way to answer this question is to get a tape measure and go to your attic. If you don’t have 20 inches of insulation in your attic then you need to add insulation to your attic.  Twenty inches will provide a good layer of insulation to keep your home cool in the summer and warm in the winter.

Insulation is measured in R-value.  R-value is a measure of resistance to heat flow through a given thickness of material.

In theory, the higher the R-value, the greater that resistance.

Unfortunately, R-Value has taken hold in the consumer’s mind as a universal method for comparing insulations. The higher the R-Value, the better the insulation, end of story.   This is a little simplistic since other factors also determine your insulation’s effectiveness.  If your insulation R-value is high but leaving gaps for air then the high R-value isn’t making a difference.

This is why Excel Roofing recommends 20 inches of loose fill fiberglass insulation.

Types of Attic Insulation

Different types of insulation include blanket roll, loose fill, fiberglass and cellulose.  Cellulose has a tendency to settle and compact which loses the air pockets which are valuable in keeping your home insulated.  Fiberglass maintains its form for a longer period of time.   Blanket roll, or batts, doesn’t fill the space well.  They leave gaps between the rolls and edges of your attic frame and joists.   Blown in fiberglass insulation provides the best insulation for your home.

Not only will insulation help lower your energy costs, but there are insulation rebates and tax credits available.   You can take advantage of tax credits for insulation from the state and federal government, up to $800 between them.

Xcel Energy is also offering a maximum insulation rebate of $300 for attic insulation.

Right now, Excel Roofing and Exteriors is offering $250 off a complete attic insulation job.  If you take advantage of our rebate, Xcel Energy’s rebate and the tax credits, that is a potential savings of $1350.

And that doesn’t take into account how much you can save off your monthly energy bill.

Our installation method is quick and clean.  If you’re having a roof replaced, we simply run the hose through the roof.  If not, we can use an attic vent to get the hose into the attic.  Watch this insulation video for a demonstration of our insulation installation.
