The Best Insulation Options for Your Home

There is no one size fits all when it comes to insulation. Before you begin, there are several things you’ll need to determine.

In this article, we’ll discuss some popular types of insulation, and the factors you need to consider when deciding the best options for your home.

How to choose the best insulation for your home

The factors that influence your decision include:

  • Climate/location: It is important to consider your climate and where you live so that airflow can be managed in your home.
  • Project scope: Some insulations require wall removal. However, spray foam, blown-in fiberglass and cellulose can be applied with a hose using no structural modifications.
  • Budget: Costs vary by material and method.
  • DIY or professional? Some insulation options can be done by homeowners. Others require professionals.

Different types of insulation

There are four types of insulation that are commonly used in homes. Each type has its own benefits, but not all options will work for you. Let’s discuss these different types of insulation to determine which will benefit you the most.

Spray foam insulation

Spray foam is the easiest way to insulate your home without major construction. It’s a chemical-based product that you mix at home and then spray it using a special sprayer. Spray foam is a great choice for cold climates because of its ability to penetrate tight spaces.

Here are some of the pros and cons of spray foam insulation:

Pros

  • High R-value is a measure of heat transfer resistance.
  • Water resistance and vapor barrier are excellent to protect against weather events
  • Resistant against mold
  • Resistant against insects
  • Both suitable for older and newer homes
  • Ideal for sealing small crevices

Cons

  • Higher prices for labor and materials than other options
  • It is very difficult to install yourself

Fiberglass insulation

Fiberglass is the most commonly used insulation in homes. It is made up of very fine glass fibers. You can find it in rolls, loose fill, rigid boards, as well as specialized duct insulation.

Fiberglass installation costs can range from $1,000 up to 2,400. However, if you choose to DIY, the material costs only $0.30 up to $1.50 a square foot.

You can find fiberglass rolls in all major home improvement stores. To install, simply push them between the wall structure or joists. This will increase the R-value of your home greatly.

Now, here are a few pros and cons of fiberglass:

Pros

  • Extraordinary for reducing heat loss
  • Fire-resistant qualities
  • If homeowners have the necessary DIY skills, they can install.
  • Insulation companies can do a quick and easy job of installing insulation.
  • Affordable

Cons

  • Fiberglass can pose a danger if it is not properly handled or inhaled
  • Spray foam in colder climates is less effective than spray foam
  • Sometimes, you will need to take down walls in order to install rolls

Cellulose insulation

Less known than our previous two, cellulose is thick and dense. Cellulose is an eco-friendly choice because it comes from plants.

Let’s look at the pros and cons of cellulose insulation:

Pros

  • You can settle into the spaces and obstructions of walls and attics
  • Affordable
  • Loose-fill cellulose is easy to fill without tearing down walls
  • Repels vermin and insects

Cons

  • Sometimes, hot or cold air can be transferred through thermal bridges that are formed when it settles or compresses over time

  • It takes a while to dry because it absorbs moisture

  • There is a greater risk of mold and mildew with insulation materials than with other types

Mineral wool insulation

Mineral wool, which has a higher R value than fiberglass insulation, is known for its remarkable benefits for sealing and quieting your home.

The pros and cons of mineral wool insulation are:

Pros

  • Many times, these items are made with 30% recycled materials

  • Mineral wool has three times the density as fiberglass and blocks out noise pollution
  • It is fire resistant and can slow down fire spread in homes.
  • Its hydrophobic properties prevent it from absorbing moisture, which can lead to mold or mildew.
  • Mineral wool is made with stronger batts and will not flop as much as fiberglass.
  • Mineral wool batts are extremely stiff and can be held in place without the use of wires or staples.

Cons

  • Less expensive than fiberglass
  • Available in different sizes
  • Installation can be challenging

  • Eco-friendliness
  • Pest Control
  • Ceilings, unfinished attic floors, and open wall cavities

Cellulose is a plant matter-based product that can help you save energy and be eco-friendly. It is easy to blow in and has a high R-value. 

It also contains boric acid, an insect repellent, is an exceptional choice to stop insects from entering your home.

Finally, insulation made from blown-in cellulose is ideal for insulating difficult-to-reach areas.

Fiberglass

Best for:

  • Those on a budget
