Inspecting your attic insulation.

How thick should insulation be in an attic.

Add the right kind of insulation when adding additional insulation you do not have to use the same type of insulation that currently exists in your attic. The thicker the better. It is not uncommon to see 15 to 20 of insulation in a well insulated attic. They range from around 1 to 3 inches in thickness and can be used in multiple applications ranging from walls to attics.

For loose fill cellulose this translates to a total depth ranging from 8 inches. First things first you need to go up into your attic inspect the condition of the insulation and calculate the current level of insulation. The most common form that insulation comes in is a batt or blanket these are large rolls of insulation that are easy to cut into usable shapes. In temperate coastal areas such as zone 3 attic insulation of at least r30 up to a maximum of r60 is recommended.

Your attic should have a certain amount of insulation in it and the recommended level of insulation for your attic is dependent on where you live. The insulation in your attic should be at least 12 thick. So if the ideal r value for your home is r 40 your contractor may only need to spray five inches of foam insulation. Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.
