The Basics of Blown-in Attic Insulation and Its Benefits

As a homeowner, it’s your responsibility to protect your home from the elements because they can cause significant damage if ignored. While most parts of a house are usually taken care of, the attic is often forgotten because it’s not somewhere people often go. The attic can sustain significant damage if ignored because it makes the foremost contact with the elements. Luckily, blown-in insulation is an option.

Insulation is essential because it reduces the energy needed to heat or cool a building. Different types of insulation are available, but blown-in insulation is particularly effective for attics because it can be used in hard-to-reach places, which improves protection. However, many homeowners doubt this because they think it’s expensive. This is never the case, so we’ll discuss the details in this article.

How Blown-in Insulation Works

A blower is used to spray the insulation material into the attic to ensure it’s evenly distributed. The material is usually cellulose that’s been shredded, which makes it easy to pack into areas. The insulation is sprayed into the attic through a hole drilled into the attic’s floor. The hole must be big enough for the blower, usually about the size of a dryer vent.

Once the insulation is in place, it will settle into every nook and cranny to create an effective barrier. The cellulose is usually treated with a fire retardant to ensure it’s safe to use. It’s also treated with a chemical that helps it repel pests because they can cause significant damage to insulation. The insulation is also treated with a material that helps it resist mould growth because it’s essential to keep the attic dry.

For the final step, the hole is sealed with a special plug. The plug is made from the same insulation material, making for a seamless fit. The hole can be drilled in the same place every time the attic is insulated to ensure the insulation is evenly distributed. The insulation can also be added to the attic’s walls to protect them.

The Benefits of Blown-in Insulation

If you install blown-in insulation in your attic, you can reap the following benefits:

Easy Installation

Blown-in insulation is easier to install than other variants, such as fibreglass or cellulose. It doesn’t require the same level of expertise, meaning it can be done in a shorter amount of time.

Energy Efficiency

Blown-in insulation is energy-efficient, helping you save money on heating and cooling costs. By sealing your attic and keeping heat from escaping, you can make your home more comfortable and reduce energy bills.

Improved Indoor Air Quality

Blown-in insulation also provides a barrier between your home and the outdoors, which benefits those with allergies. By keeping out pollen, dust, and other airborne contaminants, you can help improve the air quality inside your home.


Eco-friendly insulation is becoming increasingly popular as homeowners look for ways to green their homes. Blown-in insulation, in particular, is an excellent option because it’s made from recycled materials. It’s also free of chemicals and other harmful substances, making it a safe choice for your home.

The Cost of Blown-in Insulation

There are different types of insulation available on the market today. While some types are more expensive, blown-in insulation is one of the most affordable. It costs between $0.35 and $2.00 per square foot. Of course, the exact cost will depend on several factors, including the type of insulation you choose and the size of the area you need to insulate. However, blown-in insulation is still a cost-effective option even if you need to insulate a large area.


Getting blown-in insulation for your attic is an effective way to protect it because it can do more than the average insulation. Since it costs less than other types of insulation, you will get a great return on your investment. All that matters is finding the best quality insulation from a reputable company.
