R value ratings vary among different types and forms of home insulations and among products of the same type and form.
Different types of insulation for attics.
And much of it is diy able.
Blowing insulation into an attic the most popular project for using blown in insulation is adding insulation to attics.
Wall insulation can reduce a home s heat loss by 67 while attic insulation can lead to a 40 decrease in heating and cooling costs.
The higher the r value the better the thermal performance of the insulation.
Loose fill or batt the common term for blanket insulation.
For diy attic insulation you ve got two choices.
Read on to learn about the different insulation types costs uses and whether you should diy it or hire a pro.
Insulation types include loose fill batts rolls foam board spray board and vapor barriers.

The type of insulation you need depends on which type is currently installed and the required r value.
Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
