What is the most popular insulation material?
Fiberglass. Fluffy fiberglass batting or chopped blown fiberglass are two of the most popular types of home insulation in the United States. This material is made up of many tiny glass threads with air spaces between them. The trapped air helps keep heat from escaping through the material.
How does insulation help a home?
Many materials with poor insulation values still help homes stay warm in cold weather and cool in warm weather. This is due to their density, which translates to a high thermal mass. Very dense materials, such as brick, stone and some hardwoods, heat up and cool down very slowly. They can retain heat over a long period of time rather than transferring it directly into the home or the outside air, the way metal and glass tend to do. Combining high thermal mass materials such as brick with high insulation value materials such as fiberglass can help reduce the amount of energy needed to heat or cool a home.
How much R value does fiberglass have?
According to Colorado Energy, fiberglass batts provide an R-value of between 3.14 and 4.30 per inch. Blown fiberglass in walls and attics provide between 2.20 and 4.40, depending on how tightly the fiberglass is packed.
What does R value mean in insulation?
Builders express insulation effectiveness as an R-value, or the measure of heat flow resistance. Higher values indicate a more insulative material; lower values indicate a material that allows more heat to pass through.
Why do some materials have a high thermal mass?
Thermal Mass. Many materials with poor insulation values still help homes stay warm in cold weather and cool in warm weather. This is due to their density, which translates to a high thermal mass. Very dense materials, such as brick, stone and some hardwoods, heat up and cool down very slowly.
What is the R value of framing wood?
Framing wood usually averages an R-value of around 1.25 per inch, or around 4.38 per 2x4. Most hardwoods have R-values around 0.71 per inch, making them a poorer choice for keeping heat in the home, despite their durability. Like brick, wood homes are usually augmented with extra insulation. Advertisement.
Is oak a good insulator?
This material is lightweight, inexpensive and provides better insulation than brick but is still a relatively poor insulator. In general, denser woods, such as oak, have a lower R-value than less dense woods, such as pine. Framing wood usually averages an R-value of around 1.25 per inch, or around 4.38 per 2x4.
How to improve insulation in a house?
If you're starting from scratch and building a home then using insulated concrete forms, which is literally building the insulation into your home's structure, is the way to go for maximum efficiency. However, if you're remodeling an existing home, spray foam is probably the best option for maximum energy efficiency. Loose fill cellulose or fiberglass can also be sprayed into existing structures. So when it comes time to add or improve insulation in your house, look for the one that has the most appropriate R-value that works best for your home's needs. This will depend on the age of your home, the structure itself and where your house is located. A house in Minnesota will have different needs than one in Florida. In the end though, the goal is the same – you want to provide effective resistance to the flow of heat and cold air.

What is the best way to save energy?
Energy Saver. Insulation. Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort.
Does radiant barrier have R value?
As such, a radiant barrier has no inherent R-value. Although it is possible to calculate an R-value for a specific radiant barrier or reflective insulation installation, the effectiveness of these systems lies in their ability to reduce heat gain by reflecting heat away from the living space.
Does insulation increase R value?
In general, increased insulation thickness will proportionally increase the R-value. However, as the installed thickness increases for loose-fill insulation, the settled density of the product increases due to compression of the insulation under its own weight. Because of this compression, loose-fill insulation R-value does not change ...
Does insulation reduce heat flow?
The effectiveness of an insulation material’s resistance to heat flow also depends on how and where the insulation is installed. For example, insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because heat flows more readily through studs, joists, and other building materials, in a phenomenon known as thermal bridging. In addition, insulation that fills building cavities reduces airflow or leakage and saves energy.
What is EPS insulation?

Why do you need insulation for your furnace?
This also helps to keep your air conditioner and furnace from working overtime to keep up, as long as the insulation isn't allowing for air leaks and has been routinely maintained. Another thing you want your insulation to do is to seal your home's building envelope.
Which is better, fiberglass or spray foam?
Spray foam is the better choice between the two because it doesn’t retain water and it creates an air seal. Fiberglass is the cheaper option and you can install it yourself, but spray foam creates the air seal you will want in the space. The Building Science Corporation recommends a foam-based insulation material for crawl spaces because of this. ...
Can you install fiberglass rim joists yourself?
Fiberglass is inexpensive and you can install it yourself, but it does not do as good of a job insulating the rim joist, according to Home Construction Improvement. The material when installed in the rim joist also is prone to mold issues as it holds condensation against the wood, which leads to mold and decay formation.
What is the best insulation for the underside of a roof?
