Spray foam insulation can significantly decrease your energy bills by enhancing energy efficiency and acting as an effective air barrier. Besides its benefits, you may have problems with attic spray foam insulation.
Particularly concerning health risks, spray foam insulation problems include toxic compounds in some petroleum-based products, which can have adverse health effects, especially on the respiratory system.
Problems With Spray Foam Insulation in Attics
Spray foam insulation has been the choice of homeowners and contractors. It is best for keeping the property inside your house warm and locking the moisture inside. That’s why some homeowners install it in attics, floors, and walls.
This article will not discuss its performance but possible problems if it’s not installed correctly. If you would like to know, keep reading!
Spray foam Attic insulation Pros and Cons
To give you a brief explanation, we’re ready to walk you through the pros and cons as stated below:
The Pros
- Such An Easy Insulation
When it comes to spray foam insulation, you don’t have to worry about the installation. It’s well-known as one of the easiest insulators to install, even on an uneven surface. You only need to spray the foam on the chosen area. Then, this foam will dry out in a day and is highly resistant.
- Eco-friendly
Go green or eco-friendly materials are in high demand these days. The chemicals inside, typically in closed-cell or open-cell spray foam, are materials that expand and harden, forming an effective insulation material.
The minimum materials used in the foam make the spray foam insulation able to reduce your energy consumption. In other words, this type of insulation also has the potential to be more eco-friendly.
- Prevent Bugs and Mold Growing
As the sprayed polyurethane foam fills in the gaps or small cracks in your attics, it effectively closes off entry points for bugs and mold, improving indoor air quality. On the other hand, the closed cell will reduce the water that can get in between the attics. Hence, the production of mold is getting smaller.
The Cons
Speaking of the cons, certain ways could go wrong if the spray foam insulation is not installed properly. Here there are:

- You Pick The Bad Quality
No matter how easy and effective it is, it won’t work if you pick the wrong quality of spray foam insulation. Poor spray foam still creates cold spaces between the attics. So, you need to ensure when purchasing the spray foam insulation.
- Wrong Place
Having a dream loft means providing enough space and must be measured carefully. You must get the insulation extension at least 20% of the height between your roof and the floor. If these needs aren’t met, you won’t be able to get inside the loft comfortably. So, be more careful where not to use the spray foam insulation.
- Choosing The Wrong Type of Spray Foam Insulation
Just like picking the wrong place, the incorrect type of spray foam insulation can cost you later. You have to do a little digging on the amazing advantages each spray foam insulation gives. That way, you can choose the right ones for your loft.
- Cold Air Leakage
As it’s named, spray foam insulation can’t protect some areas from air leakage where it’s not sprayed. Though this insulation is well known for its ability to withstand cold air-sealing, the determination is in your hands. It’s about how careful you are not to miss a single gap and how you understand the building structure of your house.
Even if spray foam insulation is highly common, it doesn’t mean that it’s a total winner. No matter what brand of spray foam insulation you choose, you need to do proper planning before installing and doing it properly. When the installation is done correctly, it will even help the structure of your house survive hurricanes.
Comparison of Spray Foam Insulation Pros and Cons
| Aspect | Pros | Cons |
|---|---|---|
| Installation | Easy to install even on uneven surfaces | Requires careful selection of quality products |
| Eco-friendliness | Uses minimal materials, reduces energy consumption | Potentially harmful chemicals if not properly selected |
| Bug and Mold Prevention | Fills gaps, improves air quality, reduces mold production | Incorrect placement can lead to ineffective insulation |
| Cold Air Leakage Prevention | Effective if installed correctly, can withstand cold air | Lingering odors if the attic is completely sealed, requiring additional ventilation |
| Odor Control | Proper ventilation can mitigate odor issues | High-quality insulation is achievable with well-maintained equipment |
| Equipment Maintenance | High-quality insulation achievable with well-maintained equipment | Complex equipment requires expert handling and maintenance, prone to breakdowns |
| Business Feasibility | Can be profitable with proper planning and execution | Requires significant investment in equipment and maintenance |
Additionally, while spray foam insulation can significantly improve energy efficiency, improper installation can lead to gaps and incomplete coverage, undermining its effectiveness. Therefore, it’s essential to ensure that the installation is carried out meticulously to avoid any potential issues.”
Personal Experience:
Having been involved in numerous insulation projects, I’ve encountered firsthand the issues that arise from improper spray foam installation. One notable instance was a project where the homeowner reported persistent odors post-installation.
Despite our best efforts and quality materials, the sealing of the attic caused the odors to linger, leading to discomfort and health concerns for the residents. We had to install additional ventilation systems to mitigate the issue, highlighting the importance of proper installation and thorough ventilation planning.
Another critical aspect is the maintenance of the spray foam equipment. In our experience, the complexity of the equipment, including reactors, hoses, and guns, often led to breakdowns, causing delays and additional costs.
This not only affected our schedule but also the overall satisfaction of our clients, reinforcing the need for expert handling and maintenance of the equipment.
So if you’re thinking about insulating, you should consider the problems with spray foam insulation in attics. Make sure you choose the right type and pick the right place to avoid any problems in the future.
