To get the marked R-Value, it is essential that the insulation be installed. In warmer climates you can get away with R-insulation in the attic. Where you live also affects which insulation you choose.
How insulation works is expressed by its R-value, which is the measure of. R - rating in cold climates and an R-in warmer parts of the country.
