Once you ve decided which type is best for you examine the material options and prices to home in on the right product.

The higher the r value the better the thermal performance of the insulation. You can mix the type and material of insulation too.

For diy attic insulation you ve got two choices. The ideal attic insulation r value is different than the ideal wall insulation r value. Insulation level are specified by r value. Typically placed in areas where air escapes such as between the stud cavities inside the walls and in the attic it.

Blowing insulation into walls. Loose fill or batt the common term for blanket insulation.
