They sport insulation values of approximately r 6 5 and r 3 6 per inch respectively.
Differences in insulation for attics.
Some installations can yield a higher r value than traditional batt insulation for the same thickness and can fill even the smallest cavities creating an effective air barrier.
Spray foam offers the best attic insulation performance available.
R value is a measure of insulation s ability to resist heat traveling through it.
Foam in place insulation can be blown into walls on attic surfaces or under floors to insulate and reduce air leakage.
The table below shows what levels of insulation are cost effective for different climates and locations in the home.
Make sure your home is properly insulated in all these locations.
Rolled insulation is another type of insulation blanket similar to batt insulation.
Blowing insulation into an attic the most popular project for using blown in insulation is adding insulation to attics.
It s a fast and easy diy project that two people can do in an afternoon.
Insulation level are specified by r value.
Insulation ratings can be improved by adding more layers of insulation.
Both can be added to uninsulated attics or layered over existing material.
You can mix the type and material of insulation too.
The ideal attic insulation r value is different than the ideal wall insulation r value.
Blowing insulation into walls.
Insulating basement walls or slab foundation can reduce heating costs by10 to 20.
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.
For diy attic insulation you ve got two choices.
10 of your home heating bill costs stem from uninsulated floors.
Here the insulation can be blown right over top of existing insulation to any depth or r value.
So it s time to pay close attention to what s happening up there.
Loose fill or batt the common term for blanket insulation.
Proper attic insulation is the best way to prevent heat loss in the winter and retain cool air in the summer.
Insulation is a vital component in any home that aims to be energy efficient.
When installed properly both types of insulation fill all of the nooks and crannies in a space and.
Once you ve decided which type is best for you examine the material options and prices to home in on the right product.
Best for attics unfinished walls ceilings floors and attached garages in hot climates.
Achieving greater r values in attics.
The higher the r value the better the thermal performance of the insulation.
Closed cell and open cell aka 2 pound and pound respectively.
