Differences In Insulation For Attics

The higher the r value the better the thermal performance of the insulation.

Differences in insulation for attics.

Loose fill or batt the common term for blanket insulation. Blowing insulation into walls. Spray foam offers the best attic insulation performance available. Choose from two types.

Insulation level are specified by r value. Insulation is a vital component in any home that aims to be energy efficient. The main difference between insulation batts and rolls is that batts are installed in pieces while rolls are rolled out between wall and ceiling framing. Achieving greater r values in attics.

So it s time to pay close attention to what s happening up there. When installed properly both types of insulation fill all of the nooks and crannies in a space and. 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. Best for attics unfinished walls ceilings floors and attached garages in hot climates.

Typically placed in areas where air escapes such as between the stud cavities inside the walls and in the attic it. Proper attic insulation is the best way to prevent heat loss in the winter and retain cool air in the summer. Blowing insulation into an attic the most popular project for using blown in insulation is adding insulation to attics. Here the insulation can be blown right over top of existing insulation to any depth or r value.

They sport insulation values of approximately r 6 5 and r 3 6 per inch respectively. Insulating basement walls or slab foundation can reduce heating costs by10 to 20. 10 of your home heating bill costs stem from uninsulated floors. Closed cell and open cell aka 2 pound and pound respectively.

Make sure your home is properly insulated in all these locations. R value is a measure of insulation s ability to resist heat traveling through it. Once you ve decided which type is best for you examine the material options and prices to home in on the right product. The ideal attic insulation r value is different than the ideal wall insulation r value.

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.
