What is the best and cheapest type of attic insulation?

There are a number of different types of attic insulation available for your home. Which one you go ahead with depends on your budget, which in turn is determined by the size of the attic. Attic insulation is critical to have a more weather-protected home as well as to save big on electric bills in the long run.

3 main kinds of attic insulation to choose from

There are different types of attic insulation and each one is good for a different type of space. Cellulose, urethane spray foam, and blown-in insulations are the four most common types. Apart from these, you can also go for loose-fill, drywalls, and foam sheeting.

The most important thing to keep in mind is that there is no clear winner when it comes to the “best and cheapest” type of attic insulation. The truth is, what the best and the cheapest option is for you depends largely on several factors.

These include where you are, what kind of attic it is, what type of tools and materials you have easily available, and most importantly, what size is your attic.

Some types are installed during construction while others are applied at a later time. Depending on your home’s layout and the area you live in, you may have more than one option. Let’s have a look at the best and cheapest attic insulation options for different situations in Canada.

Option 1: Cellulose and fiberglass batts

The best type of attic insulation is cellulose and fiberglass batts. They are the least expensive, but they also have an aggressive layer built in, so they will crack over time.

Option 2: Urethane spray foam

The second option is urethane spray foam, which has a non-aggressive layer built in and won’t crack after being installed. Spray foam is also effective at retaining heat and reducing sound transfer (what we call “dead air”). If you’re looking for an all-around best option, I would choose urethane spray foam.

Option 3: Blown-in cellulose

The best and cheapest type of attic insulation is perhaps blown-in cellulose in the majority of cases. The main difference between these and urethane foam (UBF) is the cost, although UBFs are more energy efficient.

Wrapping up

Insulation is a very important part of maintaining the efficiency of your home or business. Your attic space is not cooled enough by airflow through the ducts. In fact, the heat absorption from your house can be reduced by 50% in tight spaces! If you have an attic-conditioned space and there are no active cooling systems then insulating it is essential.

With that in mind, it becomes very important to determine which type of attic insulation to go for.
