If more Insulation may be needed
Look at your attic, if the insulation level is meeting or below the floor joists
If insulation may be sufficient
....Check for common air leaks
Go around the house and visually inspect for any cracks or other small openings in common leak sites. Click the image above to see common air leaks.
Energy Star recommends a few simple ways to check if your attic insulation levels are up to par
Tests you can perform to check insulation
Hot or cold Ceilings, walls, rooms or any uneven temperature
High heating or cooling bills

Do I need new attic insulation?
Here are some common symptoms and quick tests to help you determine if you need new attic insulation
You can simply check to see if what the R-value is imprinted on the batts on your existing insulation OR you can use a tape measure to see the depth of insulation (inches) and calculate the r-value using Energystar's table
Measuring insulation levels....
Quick check for insulation
Again, looking at your attic, if you can't see any floor joists because of insualtion, you may have enough insulation
Have an insulated attic is an important component in energy efficiency. Have properly installed insulation has many benefits other than energy efficiency. In extreme climates attic insulation provides extra protection against hot and cold air. Adding insulation is not very difficult and be do-it-yourself (DIY) project. Use the information below to help determine if new attic insulation may be necessary.
Ventilation: How it supports attic insulation and improves energy efficiency
It may seem contradictory to have ventilation in your attic where insulation is found, however, adding a ventilation system to your attic prevents issues down the road. Additionally, the attic space and the area you live in are completely different areas with their own insulation and energy efficiency requirements. How insulation and ventilation work together to increase energy efficiency can be confusing; a general rule of thumb to follow is that the more insulation you add to your attic the more ventilation is needed too.
