When insulating your home, you’ll want to consider several factors in choosing the type of insulation you will use. For many homeowners, batt insulation, which comes in pre-cut panels or rolls, is the best choice. The fiberglass and rocks in this insulation create a strong barrier against extreme temperatures.

Batt insulation is cheaper, easy to install, and offers a high R-value — which means it’s resistant to the flow of heat. While these characteristics make batt insulation a top choice, it’s not ideal for every situation. Here are a few ways to effectively use this type of insulation in your home.

1.     Insulating Attics with Batt Insulation

One of the most common uses of batt insulation is insulating attics since it fits well between rafters and attic floor joists. It’s installed quickly since most attic surfaces contain few obstructions. Even if the attic has one or two windows, the installer can cut the batt insulation to the correct dimensions. 

Before insulating your attic, make sure to request air sealing services from your contractor. Batt insulation isn’t effective for blocking airflow, so you’ll want air leaks sealed ahead of time. 

In addition to getting better protection from your insulation, sealing air leaks will reduce the risks of water damage and mold growth. In turn, that will help your fiberglass insulation last longer.

2.   HVAC Ducts

You can buy batt insulation with a self-adhesive foil backing. This type of insulation is ideal for use on the ductwork for your HVAC system. The installer won’t need many tools since the insulation presses into place. It should wrap around the ducts firmly to protect them and help retain the temperature of your treated air.


You will need a professional installer to insulate your ductwork. They will have to provide the installation when there isn’t condensation on the ducts, so plan for a day when the temperature is moderate. They will also seal the gaps in the insulation with duct tape for better protection.

3.   Walls

If you’re having a custom home built, one of your biggest concerns will be making it as energy efficient as possible. This involves choosing the best insulation for home exterior walls. Most people choose fiberglass batt insulation because it is a cheaper and highly effective form of insulation. 

When your contractor installs the batt insulation for your home, you can request varying degrees of thickness. By installing the thickest batt insulation, you’ll ensure your insulation will provide the highest R-value available. A higher R-value will give you better control over the temperature inside your new home.

4.  Crawl Space

If your home has a crawl space, insulating this part of the house can provide more protection against extreme temperatures. However, choosing the right insulation for your crawl space is especially important. 

Depending on the location and condition of the space, it may be prone to condensation or water leaks. In that case, fiberglass batt insulation may not be the best option.

If you’re reasonably sure that your crawl space stays dry throughout the year, you can install batt insulation. The installer will need experience installing insulation in tight spaces since this can be tricky. 

Once installed, keep an eye on it for damage, moisture, and mold growth. If you notice any of these signs, you must replace the insulation.

Professional Installers Can Help

Handling batt insulation can be hazardous. It can cause skin irritation and respiratory issues. This is why you should rely on a professional installation service rather than trying to install the insulation yourself. Your insulation contractor will have protective gear and provide you with a higher quality of service.
