Insulation is rated according to its ability to resist the flow of heat from one space to another. This rating, known as R-value, is an important factor to consider when deciding which insulating material will provide the most effective heat barrier for your home.
The R-value, which is determined by the type, thickness and density of an insulating material, can tell you at a glance whether a certain type of insulation will provide adequate protection for your home. The most effective insulating materials have the highest R-values, while less effective materials have lower R-values.
If you live in Northern Indiana or Southwest Michigan, you can use the following general guidelines to help you determine effective R-values for insulating your home:
- Attics should be insulated to at least R-49.
- Floors that are over unheated spaces should be insulated to at least R-25.
- Wall cavities should be insulated to at least R-15.
- R-5 insulative sheathing should be installed under exterior siding to form an effective heat barrier for your home.
Many homeowners think of home insulation as a do-it-yourself project. However, because the heat barrier formed by insulation is such a vital part of your home’s overall energy efficiency, you may want to consider hiring a professional to do the job for you. In many cases the cost of installation can be easily recouped through energy savings over time.
A well-insulated home can improve the overall effectiveness of your HVAC equipment, helping to keep your home comfortable year-round while lowering your heating and cooling costs.
