Advantages and Limitations of Spray Foam Insulation

Advantages and Limitations of Spray Foam Insulation

Insulation is the best way to reduce the cost of heating and cooling systems. In addition, there are many benefits that convince us to install new insulation or upgrade our old insulation.  Spray foam is now widely used as insulation that has been available to homeowners since 1986. As a specialist installing spray foam insulation in Richmond Hill explains, this is one of the newest innovations in home insulation that undoubtedly offers comfort, convenience, and energy efficiency benefits. Let’s take a look at the benefits and limitations.

There are two types of this insulation called open-cell and closed-cell. The former is thicker, cheaper, very soft, and springy. The latter is strong insulation with more benefits and more expensive.

The most important advantage of this type of insulation is the creation of strong seals against the air. Almost every homeowner knows that the biggest cause of high energy bills is air leakage, and when you go through this insulation, you are actually taking a big step to save money.

Other unique features include the ability to penetrate and prevent cracks and holes. When the foam is applied directly to cracks, it expands and dries while blocking air and water. But air and water are not the only elements that are blocked by foam insulation. Heat and cold cannot also move inside or outside. As a result, your heating and cooling costs are significantly reduced. Therefore, it can be said that while others believe that this insulation is expensive, it is very beneficial in the long run because it leads to low energy bill costs.

Another interesting and useful thing about this type of insulation is that its installation does prevent a source of bacteria from growing. This means that there is no mold in your home.


For those who are always concerned about the environment, professionals at Weaver Eco Home explain that this insulation is environmentally friendly. If you do not know why it is claimed to be environmentally friendly, just pay attention to its benefits. Reducing energy consumption, preventing the growth of bacteria, producing less consumed materials, long-term durability, and indefinite lifespan are all factors that prove this claim.

But in addition to the benefits mentioned, there are some limitations that need to be considered. For example, if there are electrical boxes, you are not allowed to use foam insulation. This is very dangerous. Instead, low-expansion foams can be used. The ceiling boxes are the same as the previous ones. The probability of fire is high.

If you are allergic to reactive chemicals, consult a specialist before installing foam insulation. Especially people with asthma should not install this type for their home.

Closed cells are better when choosing the right type for the roof because moisture can easily get out of the other type.

Finally, if you are confused about choosing the best type of insulation for your home, it is best to consult a specialist. He considers all the factors and then offers the most suitable one according to your house and area.
