Spray Foam Insulation

Energy loss through inefficient windows and doors is a drag on the quality of life for the whole family. Lower bills don’t make themselves; you need to take control of your situation and start saving money by improving your home’s insulation.

The problem is that there are many insulation products, and it’s hard to know which is the best for a particular job. Get help on spray foam insulation for your home or business from the experts at Stellrr Insulation & Spray Foam. Read to learn if applying spray foam insulation is a good choice.

Types of Spray Foam

There are two types of polyurethane foam. 

Open Cell

Open-cell spray foam gets sprayed into wall cavities, cracks, and crevices. It comes out as a liquid and expands to fill the space. It becomes solid once it has dried. This spray foam insulation is not ideal for use in areas where it will get wet frequently since it will lose its insulating properties when exposed to moisture.

The density of open-cell foams is around 0.4 – 0.5 lb./cu. Ft. The density can be adjusted when using closed-cell foam as insulation or on top of a building. It has an R-value of 3.0-4.0. 

Closed Cell

Closed-cell spray foam insulation is similar to open-cell spray foam insulation in that it expands when sprayed into an area. Still, this spray foam does not absorb water and does not lose its insulating properties when exposed to moisture. Closed-cell spray foam can be used in areas prone to getting wet due to weather or other factors like plumbing leaks or flooding because it will not soak up any water as open-cell spray foam does.

Roofing contractors utilize closed-cell foam with a density of 2.8 to 3.0+ lb./cu. In contrast, insulation projects call for a density of 1.7 lb./cu. Ft.- 2.0 lb./cu. Ft. Its R-value ranges from 3.2-3.8.

Low-Density Spray Foam

The cells are not closed but denser than those in open-cell spray foam. Comparatively, it has a higher R-value starting at 3.6 per inch and lowers vapor permeability. Low-density spray foam is for exterior insulation, though it can be used in any part of the house.

Pros of Applying Spray Foam Insulation

Spray foam insulation is a popular method because it provides a high level of comfort and energy efficiency in your home. Here are some reasons why you should use spray foam insulation for your home:

  • It Minimizes Air Leaks. Air leaks can account for up to 40% of heat loss in your home. Spray foam insulation minimizes air leaks by filling gaps between walls, floors, ceilings, and around pipes, wires, and ducts. It helps prevent heat transfer from one area to another, reducing energy costs associated with heating or cooling your home.
  • It Is Durable. Spray foam insulation is durable because it has a closed-cell structure that provides resistance against water damage and mold growth. It also prevents moisture penetration through cracks or holes in walls or ceilings without compromising its thermal properties
  • High R-Value. It provides a superior R-value compared to other insulation materials like fiberglass or cellulose. You can expect an R-value of between 3.5 and 7 per inch, depending on which spray foam insulation you choose and your application method.
  • Resistant to mold. Spray foam is resistant to mold, so you won’t have to worry about cleaning it up if it gets wet.
  • It’s safe for humans. Spray foam can be used in areas where people are present, such as basements, crawl spaces, and attics. It doesn’t contain any hazardous chemicals or materials that could harm people if they come into contact with it.
  • Blocks noise – The density of spray foam makes it an effective sound barrier for homes near busy roads or other sources of noise pollution. Its lowest density is 0.5lbs.

Cost of Spray Foam Insulation

The cost varies by size and type of installation, but it is typically around $1.36 to $2.63 per square foot. The cost includes the material, labor, equipment rental, and other fees.

The average spray foam insulation cost is approximately $627-$8000. The actual price will vary depending on factors like the amount of insulation needed, the size of the home, and geographical location.

For years, people have sprayed foam attic insulation to add insulation. Spray foam insulation fills any gaps that might be present between wall studs, one that would allow air to escape from the home. It also keeps moisture from getting into the home’s walls. Spray Foam insulation cuts costs on your energy bill for heating and cooling because it seals up the walls of a home where air and water are commonly escaping.
