Are you considering spray foam insulation for your home? Wondering if it’s possible to do it yourself? Whether you’re a DIY enthusiast or looking for professional help, this guide will help you make an informed decision about spray foam insulation.
Understanding Spray Foam Insulation
Before deciding whether to install spray foam insulation yourself, it’s important to understand what exactly this material is and why it’s useful for insulating buildings.
Spray foam insulation refers to polyurethane-based foam that is spray-applied into cavities and gaps as a liquid and then expands into a solid foam insulation material. The two main types are open-cell spray foam and closed-cell spray foam.
Open-cell spray foam has a low-density, sponge-like structure with small cells. Closed-cell foam has a higher density, rigid structure with smaller cells filled with gas. The differing cell structures give the foams different insulation properties.
When installed correctly in walls, attics, crawlspace, and other areas, the expanding foam insulates and air-seals. The tight seal prevents conditioned air from escaping and outside air from entering the building.
There are several reasons spray foam insulation has become popular for both new construction and renovating older homes:
- Excellent insulator: Foam insulation provides 3-4 times better insulation value per inch compared to fiberglass.
- Air sealing: Foam expands and seals cracks and gaps that cause energy losses from air leakage.
- Versatility: Foam conforms to any shape and fits irregular cavities.
- Moisture resistance: Closed-cell foam resists water intrusion and condensation risks.
- Noise reduction: By soundproofing walls and floors, spray foam reduces outside noise transmission indoors.
- Durability: Once cured, foam is inert, stable, and long-lasting for decades.
For these reasons, proper spray foam insulation can save energy, reduce noise, add comfort, and create a more durable building enclosure.
The two main types of spray foam insulation each have their advantages and ideal uses:
Open-cell foam is softer and sponge-like, better for simple insulation but prone to moisture issues. Closed-cell foam is more rigid, has better insulation per inch, and resists moisture and air leakage. This makes it ideal for walls, roofs, and exposed applications. Installers determine which type to use based on the specific building physics and needs of the project. Closed-cell foam is more common for DIY applications.
DIY Spray Foam Insulation: What You Need to Know
To spray foam insulation as a DIY homeowner, there are some important requirements related to tools, materials, and safety precautions.
Necessary tools and materials include:
- Foam dispensing gun with hoses
- Personal protective equipment like gloves, goggles, coveralls
- Respirator mask
- Foam chemicals – A-side & B-side components
- Mixing nozzles for foam gun
- Expansion foam crack filler
- Scraper for trimming excess foam
Foam insulation chemicals must be properly stored and handled. Kits should include full instructions.
There are also key safety measures when handling spray foam insulation:
- Wear protective gear at all times when spraying to avoid eye and skin irritation.
- Use a respirator mask to prevent inhaling fumes or particles. The gases released when spraying are hazardous.
- Work in a well-ventilated area and keep the space ventilated for at least 24 hours after spraying while the fumes disperse.
- Keep ignition sources away as the vapors are flammable until cured.
- Carefully follow all manufacturer safety instructions for mixing, spraying, and cleanup.
Foam insulation is safe when dried, but the liquid chemicals require cautious handling to prevent injuries.
Should You Spray Foam Insulation Yourself?
While professional installation is recommended, some homeowners still consider tackling it as a DIY project. Understand the key trade-offs between doing it yourself versus hiring a pro before deciding.
There are some apparent benefits to spraying DIY foam insulation, like potential cost savings on labor, the convenience of working on your own schedule, and the satisfaction of completing your own home improvement project.
However, there are also numerous drawbacks and challenges:
- Requires learning proper techniques and safety measures
- Easy to make application mistakes that compromise insulation performance
- Overspray and cleanup are far more difficult than with a professional crew
- Reaching certain areas in attics or crawlspaces can be troublesome
- No guarantee of warrantied results when not hiring a certified installer
There are several reasons why using DIY spray foam kits may not be worth the hassle:
- High upfront costs just to purchase the foam rig and supplies
- The steep learning curve to use the spray equipment correctly
- Potential to improperly apply foam, leaving gaps and reducing effectiveness
- Increased health risks from direct exposure to the chemicals
- Voiding manufacturer warranties on the foam insulation
Unless highly experienced with spray foam, the costs and risks often outweigh the benefits of DIY application.
To find a qualified professional spray foam insulation contractor instead, follow these tips:
- Verify they are an authorized installer approved by the foam manufacturer
- Ask for examples of past insulation jobs to confirm the experience
- Request references from recent clients and call them to ask about the contractor’s work
- Confirm that they have the proper insurance, worker’s compensation, and bonding
- Get multiple quotes to evaluate reasonable prices
Going with a certified expert contractor is worth the investment to properly install spray foam insulation.
Conclusion: Trust the Experts for Spray Foam Insulation
While DIY spray foam may seem like a way to save on labor costs, the reality is that for most homeowners, hiring a qualified professional contractor is the far better option. Between the challenges of learning proper spray techniques, effectively sealing gaps, safely handling the chemicals, and preventing overspray problems, taking on this project without experience carries too many risks and downsides.
By hiring a certified spray foam insulation contractor, you remove those headaches while gaining peace of mind from an expert installation guaranteed to insulate your home. Verify their expertise through manufacturer approval, sample projects, client reviews, and references. The long-lasting energy savings and comfort benefits of properly installed spray foam make hiring a pro very worthwhile.

FAQs
How long does spray foam insulation off-gas?
Spray foam insulation may off-gas vapors for 24 hours after installation. Windows should be opened with fans ventilating the area for at least 24 hours.
Can you get itchy from spray foam insulation?
Yes, the chemicals used in spray foam insulation can irritate skin, eyes, throat, and lungs during application. Installers wear full protective gear to prevent exposure. The cured foam itself does not cause itchiness.
Does spray foam insulation need to be covered?
Yes, the building code requires spray foam insulation to be separated from living spaces. It should be enclosed behind vapor barriers like drywall except for some attic applications. It can also be painted with DC315 paint instead of drywall.
