Benefits of Spray Foam Insulation vs. Other Types of Insulation

Need new insulation to help keep your home warm and cozy this winter? We recommend spray foam insulation for its many benefits over other types of insulation.

You may not see your insulation, but it’s the very thing that helps you stay warm and cozy in the winter — and even keeps the heat out in the summer. So to keep your home comfortable throughout the year, you need good insulation. There are a number of materials you can choose from when it comes to insulation, but we recommend spray foam insulation. It has a stunning amount of benefits over other types of insulation. But before we get into those benefits, first let’s discuss the different types of insulation.

Different Types of Insulation

Spray foam insulation is a fairly recent form of insulation, and it’s quickly rising above the ranks of all other insulation types. However, there are many insulation types to choose from, including: 


  • Fiberglass. This is the most common type of in-wall insulation, made of glass fibers and sold in rolls, loose fill, or batting.
  • Cellulose. Cellulose is a popular eco-friendly option, made from recycled paper. However, it requires borate for fire and insect resistance. It is available in loose-fill.
  • Denim. Denim is made from recycled jeans and is easy to install, though it is one of the more expensive options. 
  • Mineral Wool. Mineral wool is often made from a combination of minerals and natural materials, and is fire resistant, coming in rolls, loose fill, and batting.
  • Spray foam. Spray foam insulation is sprayed into the walls and expands to fit the space. It is typically made of polystyrene, polyurethane, or polyisocyanurate.


When we discuss the different types of in-wall insulation, this is typically what we’re referring to. With all that squared away, let’s get into the many benefits of spray foam insulation. 


Strong Air Barrier

This is one of the main benefits of any good insulation. Spray foam insulation expands to fit any nook and cranny, meaning it is able to cover more than other materials like fiberglass, cellulose, wool, or denim. This makes it better able to block water and air, so less heat escapes and less cold air gets in. 


Blocks Moisture

When water gets into your walls, it can stick to your pipes and vents, which can cause them to rust or form bacteria, mold, and mildew. Thus it’s important to block moisture from getting into your walls. Moisture within other types of insulation can weaken it and continue to push forward, especially materials like cellulose or denim. Spray foam insulation, once it dries, is thicker and hardier, which keeps water out so your home stays dry and warm. In fact, spray foam is impregnable when it comes to water.


Reinforces Walls

Everyone wants to feel confident in the durability of the walls of their home, and spray foam insulation can help. Spray foam insulation is made of a foamy plastic that, once hardened, forms an adhesive not unlike glue. This will not only help to keep the elements out of your home, but will actually make your walls and the structure of your home stronger. Because of this, spray foam insulation lasts longer, as do your walls.


Home Comfort

With stronger insulation, you’ll be able to enjoy better comfort in your home. You won’t have to worry about pesky drafts or stuffy rooms during the summer. With a strong moisture barrier, your indoor air quality will be improved, keeping you safe from outdoor allergens. It’s also better able to stand up to cold than fiberglass or cellulose insulation. This means you’ll be able to rely less on your home heating and cooling, so you can enjoy lower utility bills. 



Spray foam insulation is not typically seen as being so eco-friendly as cellulose or denim, but it pays off in reducing your carbon footprint in the long run. Spray foam insulation expands once installed, so you need less materials to fill the space. Additionally, because of the strong air and moisture barrier, you won’t have to rely as heavily on your heating and cooling systems, so spray foam insulation will reduce your energy usage. Over time, it can be a boon when it comes to eco-friendliness. 


Noise Reduction

Do you live near a busy street where you can hear the traffic from outside? Have a neighbor whose dog barks incessantly? Good insulation can also help to block outside noise from getting into your home. It won’t be able to shut noise out completely, but it will make it seem more distant, so you can enjoy true peace and quiet in your own home. Because spray foam insulation is thick once dried and because it’s so comprehensive, it’s really ideal when it comes to noise reducing insulation.


Long Lasting 

Other types of insulation may become worn down in time, especially as they take in more water. But spray foam insulation, because it is impermeable, lasts longer than any other type of insulation. That means once you have this installed, you won’t need to open your walls back up to replace your insulation and you won’t have to worry about drafts in a few years because your insulation is becoming worn down. This will truly last for as long as you have the house. 

When you need real insulation that you can count on, it’s hard to go wrong with spray foam insulation. It’s dense, long lasting, comprehensive, and makes your home more comfortable while saving you oodles on your energy bills. Interested in having some of your own installed?
