The Difference Between Injection Foam and Spray Foam

Homeowners that insulate their homes have several choices when it comes to insulation. Foam insulation is a popular choice, but homeowners can use two different types of foam insulation. Both types insulate, but there are times when one type is better than the other. 

Injection Foam Insulation

Injection foam insulation is carefully formulated to have fantastic insulation ability. It’s one of the best types of insulation to use for noise reduction. And it’s easy to install. But typically, injection foam insulation is only used when insulation needs to be installed in tight spaces. Spray foam insulation is usually used to put insulation:

• In cracks and crevices
• Behind wires
• Behind or in front of pipes
• In small wall spaces
• Behind finished walls

If you have an older home that was built before insulation was required, it is likely impossible to use spray foam insulation to insulate those walls unless you want to tear the wall open. The application of injection foam insulation is more precise. Technicians can install injection foam insulation right through the house’s exterior to get insulation into finished walls. 

Spray Foam Insulation

Spray foam insulation is also great for insulating walls but it’s normally used on unfinished walls. When homes are being built or renovated, a crew can apply spray foam insulation to the wall’s interior. That spray foam will cling to the wall and expand, forming a great insulation barrier that will protect your home from weather, pests, and noise. Spray foam insulation is also treated with materials that resist mold and pests. Typically this is the type of installation that is used for:

• Attics
• Crawl spaces
• Inside walls
• Inside garage walls
• Inside basement walls

Spray foam insulation can also help you lower your heating and cooling costs because of the way it protects the home. 

Which Type Of Insulation Is Best For Your Home?

Figuring out which type of insulation is the best for your home requires an in-person assessment of your home. A technician will look at your home to see what type of insulation is in the home now, if any, and where the insulation needs to go. 

If you’re renovating an older home, then injection foam insulation may be the best choice because often, older homes with lots of details like built-in cabinets and moldings, require the kind of precision that you can only get from injection foam. 

But if you’re tearing down walls or opening up walls in the middle of a big renovation, then spray foam insulation, which usually costs less than injection foam insulation, may be a good fit for you.
