Closed-Cell Spray Foam Vs. Other Insulation Types

By Mike on June 8, 2017

Homes utilize many different kinds of insulation, but closed-cell spray foam insulation is widely regarded as the most efficient. When considering different insulation types, however, it's beneficial to take note of the energy efficiency rating, pricing, durability and overall value.

Closed-Cell Vs. Other Types of Insulation

Let’s explore the different forms of insulation and determine what may be the best type for you.


The Most Common

The most common form of insulation are rolls and batts. For rolls, installers lay long rolls of pink fiberglass or cellulose blankets in attics, floors and the walls of a home. Batts are installed in pieces, and are easier to install in cramped spaces. Rolls and batts are the most popular insulation type because they are the cheaanimal.

It is easy to go to a hardware store and purchase rolls or batts to install yourself. Lowers expenses and ease of installation can cost you big in the long run, though, as this type of insulations is not the most effective.


There are disadvantages to consider if you install batts of insulation yourself. The fiberglass material can cause skin, eye, and respiratory irritation if you’re not properly prepared. Heat will always travel towards the cold, so if you do not properly seal your house, you may face a freezing home in the winter and a boiling one in the summer.

Unfortunately, with batts of insulation, air still leaks out of your home. You have to take the time to seal all holes, cracks, and openings prior to placing your rolls.

Along with an inability to protect you from unwanted air flow, batts are useless against moisture and water damage. The insulation rolls are unable to stop damage to wood or plaster. The fiberglass itself can be a breeding ground for mold and mildew, and animals have been known to chew through walls and fiberglass fillings.


The Loose Approach

Blown-in or loose insulation is another inexpensive method for sealing a home. Installers spray loose particles of fiberglass, cellulose or recycled materials into crawl spaces, attics, and finished and unfinished walls. If borate is used on the materials, blown in insulation can be flame retardant while resisting water and moisture.

Loose insulation is comparable with batts in terms of price. Because of the ability to spread the material around, this method has better coverage and can get into hard to reach places.


The convenience of better spread for loose insulation can be a double-edged sword in terms of effective insulation. A big problem with the improper installation of blown or loose insulation is a lack of air sealing inside or outside.

The energy efficiency of blown insulation is harder to measure, especially in tight spaces, and can fall short of having full protection from the heat and cold. Freshly installed blown insulation can look and function very differently from older, settled insulation. Remember, a small mistake in insulation can cause big jumps in your energy bill.

Closed-cell spray foam insulation prevents the problems caused by blown or loose insulation. Spray foam insulation seals any and all gaps, and has the best R-value rating among all insulation types.


Fits Like a Glove

Closed-cell spray foam insulation does not encounter the problems that we previously mentioned when it comes to insulation types. Made from a combination of two chemicals, polyurethane and isocyanate, installers spray the foam into crawl spaces, attics, walls and anywhere your house needs to be sealed. Once sprayed, the foam quickly expands and hardens.

Advantages of Closed-Cell Spray Foam Insulation

Though it is a little bit pricier than the other installation methods, closed-cell spray foam insulation is customizable. Its expansive quality adheres to your home while leaving no space for air leakage, moisture damage or animals. Because of its chemical composition, it is impossible for mold mildew and bacteria to thrive and grow. Closed-cell spray foam insulation is long lasting and can reduce your energy bills by keeping minimizing air loss during the cold and hot months. The durable material requires less consumption of materials and less frequent reinstallation.
