What You Should Know About Blown-in Insulation and Rolled Insulation

What is the best way to improve the energy efficiency of a home? Blown-in insulation or rolled insulation, which is the most viable option to consider?

Insulation is one of the most effective ways to keep your home warm in the winter and cool in the summer while reducing energy costs. However, with so many types of insulation available, it is challenging to decide which one to choose. With a focus on the two popular home insulation options; blown-in insulation and rolled insulation, this article will help you decide on the best.

What is Blown-In Insulation?

Blown-in insulation, also known as loose-fill insulation, is made up of small, lightweight particles of material, such as cellulose, fiberglass, or rock wool. It is installed by blowing the insulation into the space to be insulated using specialized equipment. This allows the insulation to be installed in hard-to-reach areas and provides a more consistent coverage than rolled insulation.

Blown-in insulation is an effective way to improve the energy efficiency of a building because it can be installed quickly and easily. This type of insulation is particularly useful in existing buildings where it may be difficult or impossible to install other types of insulation.

Types of blown-in insulation

There are several types of blown-in insulation materials available, each with its unique properties. Here are some of the most common types of blown-in insulation:

Cellulose insulation

This is made from recycled paper and is treated with fire retardants. It has a higher R-value (a measure of insulation’s resistance to heat flow) than fiberglass insulation, making it more effective at preventing heat loss.

Fiberglass insulation

This is made from glass fibers that are blown into the space to be insulated. It is lightweight, durable, and has good thermal and acoustical properties.

Mineral wool insulation

This is made from natural rock or slag that is melted and spun into fibers. It is resistant to fire, water, and pests, and has excellent thermal and sound insulation properties.

Foam insulation

This is spray-applied insulation that expands to fill the space to be insulated. It can be made from various materials, including polyurethane, polyisocyanurate, and polystyrene, and has excellent thermal and sound insulation properties.

The choice of blown-in insulation will depend on factors such as the type of space being insulated, the desired R-value, and the budget.

Where can blown-in insulation be installed?

Blown-in insulation can be installed in a variety of spaces in a building, including walls, attics, and crawl spaces. The installation process involves using a special machine to blow the insulation material into the space being insulated. This is typically done by creating small holes in the wall or ceiling and then blowing the insulation into the space through these holes.

Additionally, if the insulation is not installed correctly, it can create air pockets that can lead to thermal bridging and reduce the overall effectiveness of the insulation.

Another drawback of blown-in insulation is that it can be more expensive than rolled insulation, especially if it is not installed by a professional. Homeowners may need to hire a contractor to install the insulation, which can add to the overall cost of the project.

What is Rolled Insulation?

Rolled insulation, also known as batt insulation, is made up of long, flexible sheets of material, such as fiberglass, rock wool, or cotton. The insulation is typically installed between the studs in walls, between the joists in the ceiling or floor, or the attic. Rolled insulation is relatively easy to install, making it a popular option for homeowners who want to improve the energy efficiency of their homes.

Types of rolled insulation

Rolled insulation is a type of insulation that comes in large rolls or batts, typically made from materials such as fiberglass, rock wool, or natural fibers. The most common types of rolled insulation are:

Fiberglass insulation

This is made from glass fibers that are woven into batts or rolls. It is lightweight, easy to install, and has good thermal and acoustical properties.

Mineral wool insulation

This is made from natural rock or slag that is melted and spun into fibers. It is resistant to fire, water, and pests, and has excellent thermal and sound insulation properties.

Cotton insulation

This is made from recycled cotton fibers that are treated with fire retardants. It is environmentally friendly and has good thermal and sound insulation properties.

Sheep wool insulation

This is made from natural wool that is treated with fire retardants. It is environmentally friendly, non-irritating, and has excellent thermal and sound insulation properties.

Where can rolled insulation be installed?

Rolled insulation can be installed in various parts of a building, including attics, walls, floors, basements, pipes, and ductwork, and for soundproofing purposes. The installation location would depend on the specific needs and climate conditions of the building. It is best to consult with a professional insulation contractor to determine the appropriate type and installation method for optimal results.

Benefits of Rolled Insulation

One of the main benefits of rolled insulation is that it is easy to install, even for novice DIYers. The insulation can be cut to size and fitted between the studs or joists in the home, providing a seamless barrier against air leaks and thermal transfer.

Another benefit of rolled insulation is that it is relatively inexpensive. Homeowners can purchase the insulation in large rolls and install it themselves, which can save them money on labor costs.

Drawbacks of Rolled Insulation

One of the main drawbacks of rolled insulation is that it can be less effective than blown-in insulation in certain areas of the home. For example, rolled insulation can be difficult to install in hard-to-reach areas, such as the attic or between the floors of a multi-story home. Additionally, if the insulation is not installed correctly, it can create air pockets that can lead to thermal bridging and reduce the overall effectiveness of the insulation.

Another drawback of rolled insulation is that it can be less customizable than blown-in insulation. The insulation comes in pre-cut sizes and densities, which may not be suitable for every home. Homeowners may need to purchase additional materials to achieve the desired level of insulation, which can add to the overall cost of the project.
