How to Choose the Right Insulation Material for Your Home: Pros and Cons of Batt, Blown and Mineral Wool Insulation


At Champion Services, we understand how important it is to have properly insulated homes. The Department of Energy recommends homes in southern climates to have 13-14 inches (R-38) of insulation and 16-18 inches (R-49) in northern climates, but unfortunately most homes in the United States are under-insulated. In this blog post, we will discuss the two most popular materials for residential insulation: batt insulation and blown insulation (loose fill). We will also go over different types of insulation materials, installation process tips, and maintenance advice. With this information, you can make an informed decision about which material to use or method of installation for your home’s insulation needs.

Types of Insulation

When it comes to residential insulation, there are two main types of materials used: batt insulation and blown insulation (loose fill). Batt insulation is pre-cut panels with different standard sizes and R-values while loose fill insulation consists of millions of pieces that create air pockets for better insulating power.

Batt Insulation

Batt insulation is the most popular type of insulation for homes because it is easily accessible and easy to service. It can also be used in combination with other materials such as cellulose or mineral wool (rockwool) to create a more effective barrier against heat transfer. The standard size for batt insulation is 15 inches wide, but they come in different lengths depending on the R-value you’re looking for.

Blown Insulation

Blown insulation, also known as loose fill, is made up of millions of tiny pieces that fit together to create an air pocket that helps trap heat and prevent it from escaping your home. This type of insulation can be installed in attics, walls, crawl spaces, and other areas where access is limited or difficult. It’s important to note that blown insulation requires specialized equipment and expertise when installing it correctly.

Sun Radiation, Air Infiltration, and Convection

Sun radiation is the primary source of heat transfer into a home during the summer months. Air infiltration refers to the movement of air through cracks and openings in your home’s structure which can cause energy loss if not properly sealed off. Convection occurs when warm air rises causing heat to escape through the roof or attic space if left uninsulated. All three factors need to be taken into consideration when deciding which type of insulation material to use in order to maximize energy efficiency in your home.

Indoor Air Quality

The type of material you choose for your home’s insulation will have an impact on indoor air quality as well. fiberglass batt insulation can release particles into the air if not properly installed or maintained over time which can cause health issues for those living inside the home. Cellulose and mineral wool (rockwool) both contain natural fibers which are less likely to cause irritation when inhaled compared to fiberglass batt insulation. Open cell foam has been known to absorb moisture which can lead to mold growth over time so proper ventilation should be taken into consideration before installation as well as regular maintenance checks afterwards. Closed cell foam does not absorb moisture like open cell foam does but it does require more energy during installation due to its density so this should also be taken into account when making your decision on which material would work best for your home’s needs.

R-Value Comparison for Different Materials

The R-value measures how much resistance a material has against heat flow so higher numbers indicate better insulating power while lower numbers mean less resistance against heat flow resulting in higher energy costs over time if not addressed properly with adequate levels of insulation material installed in your home’s structure:

• Fiberglass (batts) – R-value ~ 3.4 • Fiberglass (blown) – R-value ~ 4.3 • Cellulose – R-value ~ 3.9 • Mineral Wool (rockwool) – R-value ~ 3.4 • Open Cell Foam – R-value ~ 3.6 • Closed Cell Foam – R-value ~ 6

Installation Process

Installing insulation in your home is a great way to improve energy efficiency and reduce your energy costs. However, it’s important to get an attic and crawl space inspection first because the structure of your home might require a specific method of installation. Once you know what type of insulation is best for you, it’s time to start the installation process. Here are some tips for making sure your insulation is installed correctly.

Importance of getting an attic and crawl space inspection first

Before installing any type of insulation, it’s important to get an attic and crawl space inspection first. This will help determine which type of insulation is best for your home and what kind of installation process is required. It’s also important to check for any existing damage or mold that needs to be addressed before starting the installation process.

Step-by-step guide to installing insulation in your home

The steps for installing insulation vary depending on the type of material being used, but here are some general guidelines:

1) Measure the area where you plan to install the insulation and determine how much material you’ll need;

2) Prepare the area by removing any old insulation or debris;

3) Install the new insulation according to manufacturer instructions;

4) Seal seams with caulk or tape;

5) Cut pieces as needed;

6) Ensure that all areas are properly insulated;

7) Replace any access panels or covers; and

8) Clean up any debris from the installation process.

Tips for making sure your insulation is installed correctly

When installing any type of insulation, there are several things you can do to ensure that it is done correctly:

1) Make sure you have enough material – having too little could result in gaps in coverage;

2) Wear protective gear such as gloves, goggles, and a face mask when handling materials;

3) Follow manufacturer instructions carefully and adhere to local building codes;

 4) Use a vacuum cleaner with a HEPA filter after completing the installation process;

 5) Check for air leaks around windows, doors, outlets, light fixtures, etc.; and  

 6) Use a thermal imaging camera to detect any areas that may need additional attention.

Safety precautions to take when installing insulation

When working with any type of insulation material, it is important to wear protective gear such as gloves, goggles, and a face mask to prevent skin irritation from particles and make sure all residue is removed properly afterwards. It’s also important to use caution when handling sharp objects like knives or scissors while cutting pieces of batt insulation or blown-in cellulose material. Additionally, be sure not to overstuff the area where you’re installing the material as this can cause air flow problems resulting in decreased efficiency levels.

Common mistakes to avoid when installing insulation

Some common mistakes people make when installing insulation include not measuring accurately so they end up with too much or too little material, not wearing protective gear while handling materials (which can lead to skin irritation), failing to follow manufacturer instructions carefully (which can lead to improper installation), not checking for air leaks around windows/doors/outlets/light fixtures (which can lead to decreased efficiency levels), and not using proper tools (like a vacuum cleaner with a HEPA filter). Additionally, many people forget about maintenance once their initial installation is complete – it’s important that homeowners inspect their insulation regularly and address any issues immediately in order maintain its effectiveness over time.

Main Idea: Installing insulation in your home is important for energy efficiency and cost savings, but there are many steps to the process, safety precautions, and common mistakes to avoid.


It is essential to maintain your insulation in order to ensure its effectiveness over time. Depending on the type of insulation you have and the climate you live in, it may need to be inspected more or less often. Generally, it is recommended that you inspect your insulation every two years or so for any signs of damage or deterioration.

How often should you inspect your insulation?

When inspecting your insulation, look for any signs of moisture, mold, or mildew, as well as any gaps or tears in the material that could be letting air through. Additionally, check for signs of pests such as rodents or insects that may have made their way into your attic space and caused damage to the insulation. If any of these issues are present, it is important to address them immediately in order to prevent further damage and loss of energy efficiency.
