The Cons of Spray Foam Attic Insulation

When the spray foam begins to pull away from the frame, other problems may develop. The only way to address this issue is to add more spray foam or remove the existing application and replace it with something fresh.


Spray foam insulation, while being a flexible solution for improving home energy efficiency, is not a one-size-fits-all remedy that can fix everything. The expanding spray foam may miss parts of the walls, ceiling, or floor because there are sometimes holes where it does not reach as it expands.

When this problem occurs, the home may have temperature regulation issues and you can hear more of the noises outside.


“Isocyanates” are some of the key compounds in this product. When they come into contact with the lungs, eyes, or stomach, these chemical substances can irritate them.

Some individuals can experience edema, rashes, allergies, and inflammation after coming into contact with the foam. When working with this material, you must wear a respirator, goggles, and gloves.


When it comes to cost, spray foam insulation cost is much more than fiberglass insulation. If you want the protection you need, expect to pay approximately $.40 per square foot for a fiberglass product.

If you choose the closed-cell spray polyurethane foam insulation, you may pay up to $1.50 per board foot.


If insulation installers overlook nooks, crannies and crevices while using a foam product, there’s an increased danger of water damage throughout the building’s life.

When the air enters the various pockets of the house, particularly those in the attic, pressure differences may cause water to seep in via building flaws.

This procedure may have a detrimental effect on the structure’s walls and roof.

Here are some additional factors to think about before deciding on the kind of insulation to use in your house:

Bump up of home value: According to preliminary findings, spray foam may be a factor in the greater resale value of properties, owing largely to the product’s energy efficiency.

Cost efficiency: Spray foam claims to reduce energy costs by up to 50%. That’s a substantial annual cost saving when you consider the rapidly increasing energy cost.

Return on Investment: Here are some intriguing facts about the pay-off of spray foam usage in your home:

  • The upfront and labor costs of spray foam insulation are usually reimbursed in less than three years. This implies that after three years, spray foam products will have paid for themselves by saving on energy bills.
  • Foam insulation, rather than fiberglass batts, saves a homeowner over $1,000 in energy expenses.

Spray foam insulation is a great product and may be a better choice than batt insulation in your particular situation. It’s a good idea to use closed-cell foam insulation because it works particularly well. It has several advantages as well as drawbacks that should not be ignored.

They are mentioned above so always keep them in mind as you plan. In the end, the sort of insulation you choose will be determined by your application, overall cost, and wants. Always seek expert advice about technical information from insulation contractors and do your homework. Good luck!
