Home insulation is so important that it’s not optional anymore and it can be considered a necessity due to the escalating cost of non-renewable energy such as petroleum. If your house is more than 15 years old or if you are renovating your house, you might want to consider home insulation as part of the work.

If you are spending too much on your monthly energy bills, it might well be due to your home’s insulation isn’t up to snuff. According to the Department of Energy, 44% of the energy used in the average American home goes toward heating and cooling. The culprit may well be at your house attic, walls or floors which are under-insulated. If you are not doing enough insulation at these parts of your house, a large part of your costly, conditioned air may be making a beeline for the great outdoors.

Before going further, the following are a couple of quick guides on home insulation, types and methods.

Why proper insulation is important for your house?
Take for example, fiber glass insulation keeps your home cool in the summer and warm in the winter because insulation resists the flow of heat. Heat is a form of energy that flows out of the home in the winter and into the home in the summer. By reducing heat flow, a properly insulated home uses less energy for heating and cooling which save you on your electricity bill.

In addition to being an energy saver, fiber glass insulation also acts as a sound absorber. When installed in walls and ceilings, it can reduce the transmission of sound from one room to another or from the outside. In today’s noise-laden environments, more and more homeowners are soundproofing their homes. A well-insulated home increases the overall comfort of the home and adds to its resale value. It pays to insulate your home no matter what your house value is.

What areas of my home should be insulated?
There are a few areas of your house that should be insulated in particular. For example, your house attics and walls are important areas that should be insulated. The attics and walls insulation gives the best deal on your return on investment (ROI) value. Other areas of your house that should be insulated as well include your house ceilings with unheated spaces, basement walls, floors above vented crawl spaces, cathedral ceilings, floors over unheated garages or porches, knee walls, and in between interior walls (especially bathrooms), ceilings or floors for extra sound control.

How do I know how much insulation I need for my home?
The amount of insulation in a home varies depending upon where you live. NAIMA has developed recommended levels of insulation for various climate zones. These recommendations are based on recommendations from the U.S. Department of Energy (DOE) and the International Energy Conservation Code which is the model building code for the United States.

What is R-value?
Insulation effectiveness is measured by R-value. “R” stands for resistance to heat flow. The higher the R-value is for a material, the greater the insulating power for that material.
In addition, manufacturers of insulation products print R-values of their products either on the bags or on the labels. In most cases, R-values are also printed on the facings of fiberglass batts and rolls.

What are the options when choosing which insulation should you be using?
There are a variety of insulations to choose from including fiber glass, mineral wool, cellulose, foam and cotton. The most common types of insulation for residential applications are fiberglass and cellulose. There are several things to consider before making an insulation decision:
• Thermal Performance – Installed R-value
• Lifetime Performance
• Fire Safety
• Moisture
• Air Infiltration
• Environmental Benefits

Should I remove existing insulation to my home before installing a new one?
Since R-values are cumulative, there is no need to remove what you already have. By layering two different batts together, you get the combined R-value of both batts. For example, two layers of R-19 batts will give you a total of R-38. Be sure to use unfaced R-19, R-25 or R-30 fiber glass batts and lay them cross-wise to the existing insulation covering the joists. Do not put a product with a vapor retarder or facing on top of existing insulation. If there is no insulation in your attic, use R-30 or R-38 full width, faced batts, or fiber glass loose-fill installed to the required R-value.
