I don’t know about you, but I do not know a whole lot about housing insulation.  I know it’s important and that it helps keep the house cooler in the summer and warmer in the winter and that’s about it!  So I read an article titled, “How Green is your attic?” and found it really helpful and wanted to share some of the information I learned with my readers.

So we all know if we add insulation we can lower our power bills and everyone wants to lower bills in this economy.  But how do you know if the savings on your power wills will outweight the cost for installing the insulation?  There’s a really cool website at http://www.energysavers.gov/your_home/insulation_airsealing/index.cfm/mytopic=11360 where the Department of Energy (DOE) can help calculate payback periods.  This will help you to know how long it will take to pay back insulation costs.

Not sure which materials are the best to install?  Visit http://www.coloradoenergy.org/procorner/stuff/r-values.htm to see an R-value chart. 

Not sure how much insulation you’ll need?  The Department of Energy (DOE) provides a map with recommended R-values for your area at http://www.energystar.gov/index.cfm?c=home_sealing.hm_improvement_insulation_table .

There are many types of insulation including the fiber blankets that come in rolls or batts, loose-fill material that can be blown in, and spray foams which expand to fill nooks and crannies in the home.  There are many options for each type of insulation including cotton, fiberglass, and cellulose.  The important thing to remember is proper installation is what tightens the home.   Any insulation that’s poorly installed can waste your energy saving dollars.
