R 38 attic insulation depth.
If you think you re among the 90 of us homes that are under insulated 1 performing a simple insulation inspection will help you determine your insulation needs.
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.
In temperate coastal areas such as zone 3 attic insulation of at least r30 up to a maximum of r60 is recommended.
R value is a measure of insulation s ability to resist heat traveling through it.
The higher the r value the better the thermal performance of the insulation.
Obtain a specific r value.
This calculator is to be used as an estimating tool only.
The recommended level for most attics is to insulate to r 38 or about 10 to 14 inches depending on insulation type.
Having the correct amount of attic insulation can help you maintain a comfortable temperature throughout your home and help save money on your energy bills plus prevent major issues like ice dams in the winter.

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.
R values like r 38 are used by the construction industry to describe the thermal resistance of insulation materials like those used to insulate your attic when you are looking at an r 38 insulation you are actually reading a description of its resistance rather than size or thickness of the material.
Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
