What is the most efficient insulation?
Fiberglass insulation still allows for airflow into the attic. Spray foam insulation is the most energy-efficient insulation to create an air barrier in the attic. Certain spray foams can expand up to 100 times its original size, so it fills all of the nooks and crannies in the attic.
Can a house have too much insulation?
It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That's when mold starts to grow.
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.
Is thicker insulation better?
Thicker is better Insulation does the same thing for a house. The thicker the insulation, the better it works to reduce heat flow from the inside of a home to the outside during winter, and from outside to inside during summer.
What is a good R-value for interior walls?
Depending on the insulation properties of the existing wall, in general the R-values of the renovated walls can be between R-19 and R-22 (0.25 to 0.30 W / m² K) - without additional risk to the structure.

The Ultimate Guide to Types of Insulation - Cielo Breez
Different types of insulation are suitable for various applications. Deciding which type is suitable depends on required R-value, cost & location.
What is the Best Type of Insulation?
Technically, there is no “best” type of insulation. All the various forms come with perks and downsides, and each is suited for different purposes. The final decision on what type of insulation would work best for your home is dependent on where you live, what parts of the house you’re insulating, your budget, and whether you are constructing your home or it’s already constructed.
What is the most commonly used insulation material?
Fiberglass is one of the most commonly used types of insulation material. It is made of fine glass fibers that are either spun or blown to create boards, rolls, loose-fill, and batts insulation. Most manufacturers use around 40% to 60% recycled glass.
How does radiant barrier insulation work?
Reflective insulation and radiant barrier insulation work by reflecting heat, unlike most other insulation materials that work by resisting heat flow. For the same reason, this type of insulation does not have its own R-value. As a result, you can install it to cool your attics, limiting summer heat gains and lowering your cooling costs.
What is spray foam insulation?
Spray foam insulation allows you to cover more surface area and gives you easy access to hard-to-reach areas. It effectively seals any cracks or gaps in your home and reduces airflow, cutting back heat loss. This type of insulation has two common forms – open-cell (less dense and filled with air) and closed-cell (high-density cells and filled with gas). It’s commonly used on walls, attic surfaces, under floors, or even below a roof.
What is loose fill insulation made of?
Loose-fill insulation is most commonly made of fiberglass, cellulose, or mineral wool. It is sold in bags and mostly requires special equipment to be blown into the building cavities.
What is the R value of insulation?
R-value of different insulation types helps determine its overall resistance to conductive heat flow. The greater the R-value of the insulation material, the more effective it is. R-value recommendations can vary based on your climate and location.
What is liquid spray foam?
Liquid spray foam insulation is sprayed, poured, foamed-in or injected as a liquid that expands and hardens to fill the available space. It is more costly than other types of insulation but has a higher R-value and saves you money on some weatherizing tasks such as caulking.
What happens if you cram insulation in a wall?
If you cram too much insulation into a wall that is too thin, you reduce the insulation's air pockets and thus reduce its ability to provide thermal resistance. A thick down-filled jacket or sleeping bag works the same way. When the feathers fluff up and create air pockets, thermal resistance is at its greatest.
How deep is a 2x4 wall?
Since modern two-by-fours are not 4 inches, the true depth of the wall cavity is 3 1/2 inches.
Can you add insulation to a cold house?
When you add too little insulation, you will have a colder house. Ironically, adding too much insulation—packing in more than is needed—can also result in a colder house than is necessary. Tiny air pockets created within the insulation are what help keep a home toasty and warm, not the actual strands of fiberglass or paper facing.
Can you force away air pockets in insulation?
Millions of tiny air pockets are basically pre-installed in the insulation and they cannot be forced away. Spray foam insulation seals all areas of the cavity: walls, floors, ceiling, along with the structural members, holes, cracks, and seams.
Does cellulose insulation fit in the attic?
Cellulose insulation does not fit the wall cavities as adequately as fiberglass insulation does. Short of rebuilding your walls to thicker dimensions—a cumbersome, expensive project—look at alternative ways of preventing your costly artificial heat from escaping: Add thick insulation batts to the attic.
Can you spray foam insulation yourself?
Long used in commercial buildings, spray foam insulation is now finding its way into more residential spaces. Spray foam insulation is not a do-it-yourself project. Generally, you'll need to hire professionals to apply spray foam.
Spray Foam Insulation
Most homeowners are familiar with spray foam insulation. It’s likely in your attic, crawl space, or around any door frames, especially in older homes where gaps and leaks have formed. Gaps and leaks are an excellent use case for spray foam insulation.
Foam Board or Rigid Board Insulation
Foam board insulation is the stiff foam boards that are installed between studs in unfinished walls. Particularly, this would be installed in your foundation or basement walls and any floors or ceilings when they’re built. This type of insulation is essential to limiting heat conduction throughout your home’s structure.
Reflective Insulation
Reflective or radiant barrier insulation works a little differently and isn’t actually measured by R-values. Best for hotter climates, reflective insulation works by, you guessed it, reflecting heat away from your home. It does this by using a reflective or radiant barrier (typically a type of aluminum foil), to bounce any direct heat away.
Blanket Insulation
Blanket batts and rolls are quite similar to foam boards, but they are made of fiberglass and are much more flexible than rigid foam boards. It’s probably one of the most common DIY-friendly and affordable options for homeowners. However, the one key thing to note is the fiberglass is highly irritant to skin, eyes, and lungs.
Loose-Fill Insulation
Loose-fill insulation is one of the most popular types, and you’ve probably seen it in many homes. It has a low R-value at just 0.44 per inch, but that doesn’t mean you should discount it.
Fiber Insulation
Fiber insulation is a type of loose-fill that’s made from recycled materials like wool, wood fibers, or cotton. The R-value for fiberboard insulation is 0.79 to 0.99 per inch, and it can work great in attics where the airflow isn’t quite as high because of its density, so it fills up the desired space much more than other types.
Concrete Block Insulation
Concrete block insulation is a newer type of home energy-saving material that’s gaining popularity. It works by filling the air gaps between between foam insulation as you stack them up on top of each other. While concrete block insulation.
How is insulation measured?
Insulation is measured through a system known as R-value, which determines how resistant different types of insulation are to heat flow, taking into account the thickness and density of the insulation material. The higher an insulation’s R-value is, the better your home’s energy efficiency and climate control are.
How much does it cost to spray foam insulation?
This’ll cost you between $1.00 and $1.20 per square foot. If it’s a bigger job, you may want to use closed-cell spray foam and/or call in a professional.
What is the R value of fiberglass batts?
A fiberglass batt generally has an R-value of between R-2.9 and R-3.8 for every inch of thickness. High-density insulation batts, like ones made out of cellulose or sheep’s wool, might have R-values closer to R-4.3 per inch.
What is foam board?
Foam boards, also known as insulating boards or rigid foam panels, are firm structures used to reduce the amount of heat conducted through wood, wall studs and roofs. Typically made of polyurethane, polystyrene or polyisocyanurate, foam boards can be used nearly anywhere in a home for both interior and exterior insulation.
What is the difference between open cell foam and closed cell foam?
There are two types of spray foam: open-cell foam and closed-cell foam. Open-cell foam is the less dense of the two, with an R-value of about R-3.7 per inch of thickness. Closed-cell foam is significantly more dense, with an R-value of about R-6.2 and, therefore, is significantly more expensive.
What is the R value of foam board?
This method is known for its reliability and effectiveness, with foam boards’ R-value coming in between R-4 and R-6.5 depending on the thickness and quality of the material. A 1 in. x 4 ft. x 8 ft. polystyrene foam board with an R-value of about for will run you around $14.
What is blown in insulation?
Blown-in insulation, also known as loose-fill insulation, is installed using a machine that blows or sprays the insulation material into the space that you are insulating. The paper-like substance used in blown-in insulation is usually made of fiberglass, rock wool or cellulose, making it flexible enough to accommodate almost any location, including tricky corners and crevices.

Why Insulate?
Home insulation provides several benefits beyond comfort. A properly insulated home provides:
Insulation R-Value
Find the color on the map that most closely matches where you live. Then find your area’s color on the corresponding R-value chart. R stands for resistance.
Types of Insulation
The chart contains information on common types of insulation, as well as tips on where and how to use them. For more comfortable installation with less itch and dust, look for encapsulated roll insulation or batting wrapped in plastic.
Where to Insulate
The easiest place to get a gauge on your home’s current insulation condition is in the attic. Insulation should be up to 19 inches thick (or R-49) for efficiency. If you don’t have enough, your home may not be properly sealed. Adding insulation to under-insulated areas and sealing air leaks may help lower energy costs.
Vapor Barrier
Moisture in the air in the form of vapor is transferred along with heat. This is especially common in humid environments and in certain areas inside a home, such as bathrooms, kitchens and laundry rooms. Trapped moisture vapor may cause mold and mildew to grow.
How Insulation Works
Insulation decreases the amount of heat entering from outside when it’s hot, and traps warmth inside when it’s cold. Insulation is rated by its R-value. R-value measures how resistant types of insulation are to heat flow. R-values vary based on the type, thickness and density of the insulation material.
How Much Insulation Do You Need?
To get an idea how much insulation is needed to cover your house, check if your home is already insulated. Then measure the area needing insulation and determine which type of insulation is best.
Types of Insulation
R-value requirements also vary based on the spot in your home in which the insulation is installed. When it comes to the best insulation for walls, the insulation material can also impact the R-values needed for good energy efficiency.
Loose Fill Insulation
Loose-fill insulation, also known as blown-in insulation, is blown or sprayed into place with special equipment. You can rent an insulation blowing machine to install this insulation yourself, but most choose to leave this installation to professionals.
Insulation Batts
Batt insulation is a type of insulation blanket. These are pre-cut sections of insulation that are usually fiberglass, although cellulose, mineral wool, natural fibers and plastic versions are also available.
Rolled Insulation
Rolled insulation is another type of insulation blanket similar to batt insulation. 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.
Foam Board Insulation
Foam board or insulating boards are rigid panels of insulation that have a high R-value. Because they have a high R-value and can be used nearly anywhere in your home, foam board insulation is one of the most common types of insulation.
What is blanket insulation made of?
You also can find batts and rolls made from mineral (rock and slag) wool, plastic fibers, and natural fibers, such as cotton and sheep's wool.
What type of insulation is used in Denver?

What is ICF foam?
ICF systems consist of interconnected foam boards or interlocking, hollow-core foam insulation blocks. Foam boards are fastened together using plastic ties. Along with the foam boards, steel rods (rebar) can be added for reinforcement before the concrete is poured.
How to evaluate blanket installation?
To evaluate blanket installation, you can measure batt thickness and check for gaps between batts as well as between batts and framing. In addition, inspect insulation for a tight fit around building components that penetrate the insulation, such as electrical boxes. To evaluate sprayed or blown-in types of insulation, measure the depth of the insulation and check for gaps in coverage.
How much air is in autoclaved concrete?
