Attic Insulation
Reading Time: 4 minutes

Numerous types of attic insulation are available on the market, so it can be challenging to determine if installing attic insulation is the right decision for your home. That’s why knowing the pros and cons of installing insulation in your attic can help. Our team will detail the advantages and disadvantages of installing attic insulation alongside the different types. Armed with this information, you will have a better idea if insulating your attic is an option you should consider.

What Are 3 Different Types Of Attic Insulation?

Before we look at the pros and cons of attic insulation, we want to discuss the 3 most common types. Knowing more about the types will better prepare you to decide based on your needs, requirements, and budget.

1. Batt Insulation

Batt insulation is arguably the most common type of insulation. It is the insulation for houses and attics that comes in rolls. Many people choose this type of insulation because it is cost-effective and doesn’t require much time or effort to install.

In addition, batt insulation is known to be moisture and fire-resistant, but its biggest downside is that it has a poor R-value rating compared to other insulation types.

2. Blown Insulation

For many people, the best insulation option is blown insulation. This type of insulation literally blows cellulose into an attic until every part that needs insulation is covered. Unlike spray foams with a high possibility of error, blown insulation gives better coverage overall.

Additionally, blown insulation is a popular choice for attics because it is environmentally friendly. It’s also cost-effective because of how easy it is to install by professionals like Art Plumbing, Air Conditioning & Electric, and it has a longer lifespan than batt insulation.

3. Spray Foam Insulation

Spray foam insulation might not be as popular as blown insulation for attics, but it is still a common insulation choice among homeowners. This is because, when properly installed, foam insulation arguably has the best insulation performance with an impressive R-value.

However, there is room for significant error with this type of insulation if a professional doesn’t perform it. This is because it is applied as a liquid and sprayed directly into an attic, where it sets and becomes a solid foam layer. Additionally, this attic insulation costs the most, so keep that in mind when choosing an insulation type.

What Are The Pros Of Insulating An Attic?

There are several pros to installing insulation in your attic. If you’ve debated it for a while but were unsure, you might find these insulation advantages beneficial to your decision-making process.

Energy Bills Lowered

Did you know that when you insulate your attic, you can significantly lower the cost of cooling your home? This means that you will have more cost-effective energy bills as insulation stops heat from flowing into your home during the summer by reducing the airflow.

It also helps your home stay cooler for longer and works with your AC to ensure you’re not sweltering while trying to go about your day indoors.

Better Air Quality

Few people know this, but if you install insulation in your home, depending on the type, you will receive better air quality. When you install insulation in your attic, you’re preventing certain pollutants like mold, radon, dirt, and smoke from entering your home.

So, if you’re experiencing frequent symptoms like respiratory problems, headaches, and fatigue, it might be time to consult a doctor and take a closer look at installing insulation in your attic.

Deters Pests

One of the biggest problems homeowners have is pests in their attics. This can be a nuisance and a health hazard. Fortunately, installing insulation can help fix this problem because pest-resistant insulation can deter them. For example, snakes, mice, and squirrels won’t get in, and birds won’t be able to build nests in your attic.

Additionally, if you already have insulation, installing a new type can help to fix some of the safety hazards you might already have. So, consider replacing your old insulation if you have pests nesting, animal droppings, or even dead animals.

Increases Your Homes Value

According to industry experts, upgrading or installing attic insulation with a high R-value can add value to your home.

What Are The Cons Of Insulating An Attic?

Only a few cons are associated with the different insulation methods for attics. Below we have briefly detailed some of the disadvantages associated with insulating your attic that you need to be aware of if you’re going to make an educated decision.

Cons of Blown-In Insulation

  • It can become messy.
  • Requires professional installation.
  • It is prone to problems when wet, leading to fungal growth.
  • Depending on how it was installed, it can lead to sagging on the ceiling.

Cons of Spray Foam Insulation

  • Significantly more expensive than other types of insulation.
  • The chemicals in the spray foam can pose health risks.
  • Not as environmentally friendly as the alternatives.

Cons of Fiberglass Batt Insulation

  • Batt insulation cannot conform to tight or oddly shaped places, reducing R-value ratings.
  • It can leave gaps that allow pests, the elements, and heat to get in.
  • Batt insulation will compress with time.
  • It can irritate the lungs and leave a person feeling itchy when exposed to it.
