Spray Foam Insulation in St. Paul – is it Good or Toxic & Dangerous?

is it Good or Toxic & Dangerous?

Spray foam is a type of insulation material that expands once you spray it. The sprayed foam expands and seals the gaps, and nooks, as well as deters moisture. Spray foam insulation effectively enhances comfort level, prevents damage, and significantly reduces your energy bills. Spray foam insulation is the most effective type of insulation.

The advantages of spray foam insulation

There are many ways to insulate your homes, offices, and commercial buildings but spray foam is the most superior solution among all due to these benefits:

Deters moisture

Seeping water from openings of pipes and vents puts your home at risk. Commonly, when building insulation gets wet, it needs to be replaced but spray foam insulation is hydrophobic and retains its all properties when it gets wet.

Improves Comfort

Spray foam insulation prevents temperature fluctuations in a building and maintains it to the optimum level. It creates an air-tight seal that protects your home and keeps it more comfortable.

Easy Application:

Spray foam insulation is very popular because of its ease of application. Spray foam works best in all seasons. It’s a non-intrusive process. A highly skilled professional just uses a spray foam gun to spray the material in your desired place and then lets it get dry.


Traditional and old insulation lose their effectiveness over time, as it is composed of powerful chemical products, spray foam insulation performs exactly how it should for decades.

Is spray foam toxic or dangerous?

Although spray foam insulation is popularly used worldwide, it has also been known to have some negative effects on health. The main dangers and toxicity of spray foam include:

  •         Asthma problems
  •         Sensitization
  •         Lung damage
  •         Other respiratory disorders
  •         The chemical composition of the spray foam has isocyanates that can cause skin, eye, and lung irritation.

But this is mainly based on older insulation methods. Modern insulation formulations of spray foam offer air quality improving properties as well.

Disadvantages of Spray Foam Insulation:

There are many benefits of using spray foam products for insulating your home, but here are a few disadvantages as well:

  •         Cost is the biggest drawback of using spray foam; it is more expensive than other insulation.
  •         It can only be installed by a professional or skilled person.
  •         It is very difficult to remove spray foam after application.
  •         It requires a long dry and curing time.
