Attic Insulation

Attic insulation plays a huge role in a long lasting roof, your heating/cooling bills and the overall comfort of your home. The most common question homeowners ask ......

Do I have enough ?

No matter what kind of insulation you currently have in your attic, one quick way to determine if you need more is to look across the span of your attic. If your insulation is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. If you cannot see any of the floor joists because the insulation is well above them, you probably have enough and adding more may still help you be cost-effective. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves there for you should top up your attic to a even distribution.


Insulation levels are specified by R-Value. R-Value is a measure of insulation's ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to between R38 witch is about 10 to 14 inches (Minimum) to R60 witch is about 16 to 22 inches (energy saving value)
