Types of Insulation
Type | Material |
---|---|
Insulating concrete forms (ICFs) | Foam boards or foam blocks |
Loose-fill and blown-in | Cellulose Fiberglass Mineral (rock or slag) wool |
Reflective system | Foil-faced kraft paper, plastic film, polyethylene bubbles, or cardboard |

What are the four types of insulation?
There are several different types of insulation, including the four most common listed below:
- Loose-Fill & Blown-In Insulation.
- Batt & Roll Insulation.
- Reflective Insulation & Radiant Barriers.
- Spray Foam & Foam-In-Place Insulation.
What are the 3 types of insulation?
Types of Insulation
- Fiberglass: Fiberglass is the most common insulation material. …
- Cellulose: Cellulose insulation is made from recycled paper products. …
- Foam: Foam insulation may be made from polystyrene, polyisocyanurate or polyurethane, which are all types of plastic.
What is the most common type of insulation?
Fiberglass Fiberglass insulation
Fiberglass. Fiberglass insulation is the most common type of insulation found in today’s homes. It comes in batts that fit between framing members such as studs or joists.
What is the most common wall insulation?
1. Blanket Batts and Rolls. Perhaps the most standard insulation form available for walls, blanket batts and rolls are typically constructed with fiberglass, although versions made of cotton, mineral wool, sheep’s wool, and plastic fibers are also available.

What kind of insulation is in my attic?
R30 in hot climates (like California) R38 in temperate climates (this is typically the desired level for residences in California)
How can you tell cellulose insulation?
If you have loose-fill insulation that is gray, soft, and without a shine, it is probably cellulose insulation. Cellulose contains a high percentage of recycled paper and does not contain minerals. In general, it looks like shredded gray paper.
What does the R mean in R-value?
resistance to heat flow
The R stands for resistance to heat flow. R-value is universal across all insulation products, so the measurement will mean the same thing no matter who sells or manufactures the insulation. R-value is even consistent across different types of insulation.
What is r19 insulation used for?
In many regions of the country, R-19 insulation is recommended for use in outer walls of new construction projects. A different type of insulation is used in areas like basements and attics, and to insulate floors.
What is standard insulation for walls?
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy’s (DOE) ranges for recommended levels of insulation below.
What type of insulation is best for walls?
The best insulation for walls when it comes to new build homes or remodels is going to be Nu-Wool, foam board, or open cell spray foam.
Cons:
- Open cell spray foam is an expensive option for insulation.
- Spray foam can’t be installed as a DIY project.
- Some brands of spray foam have an odor when installed.
What’s the difference between faced and unfaced insulation?
The Difference Between Faced And Unfaced Insulation
Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn’t fall down as much. Unfaced insulation is just as good as faced, but it doesn’t have that paper attached to it.
When should you use unfaced insulation?
Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces. It’s best used for interior wall applications that do not face the outside and also in rooms that don’t need moisture control, like living rooms, dining rooms and studies.
Do I need a vapor barrier if I use faced insulation?
Since vapor barriers are only additional protection and not required to finish faced insulation, they are not always necessary. In fact, in some parts of the United States, it is better to not add vapor barriers as they can do more damage than good to your insulation.
Can you put unfaced insulation over faced insulation?
No, faced insulation should not be added over existing insulation since the vapor retarder on top of or between layers of insulation can trap moisture. Let Accurate Insulation handle your home insulation project from start to finish.
Should you remove old insulation before putting new?
Expert contractors that specialize in insulation advise that removing old fiberglass insulation is best before installing new cellulose insulation because of possible mildew, mold, or rodent excrement.
Can you put too much insulation in your attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
Can I insulate over old insulation?
You can absolutely new insulation over old insulation… as long as it isn’t wet. Energy Star advises as follows: “If it… appears that the insulation [is wet or] has previously been wet, you should look for the cause and repair the problem to prevent a reoccurrence. Remove any wet insulation.
How do you know if your house is well insulated?
How to Tell If Your House is Well Insulated

- Pipes. If your pipes rarely freeze, that is an excellent sign of good insulation. …
- Consistent Temperatures. …
- No Water Leaks. …
- Benefits of a Well-Insulated Home.
Does doubling insulation Double R-value?
Doubling the thickness of insulation will double the insulation’s R-value, cutting heat loss in half. Each time the insulation layer is doubled in thickness, this rule applies.
