Spray Foam Insulation


Did you know that 90% of homes are under-insulated? As such, homeowners are wasting energy and money. If homeowners were to insulate their homes, electricity use would decrease by more than 20%. Spray Foam Insulation reduces indoor heat flow. The decrease in energy use lowers carbon dioxide emission and other pollutants. By doing so, each homeowner will contribute to minimizing their carbon footprint. In turn, it will help to minimize the effects of global warming.

One of the best insulation solution for homeowners today is Spray foam insulation.

What is Spray foam insulation?

As the future of insulation, it is a versatile product. Designed to provide energy efficiency, it offers better sealing. The insulation has the capability of providing a higher R-value per inch and better structural strength.

As the better option for homeowners, Spray foam insulation is made up of a chemical based liquid. Available in two parts, the insulation is normally combined before the application process. This is later sprayed in different parts of the home making it airtight and prevent the movement of heat out of the house.

To seal your home, Spray foam insulation expands beyond the floor joist and the truss. As such, it is one of the best insulation materials for filling hard to access areas.

Types of Spray Foam Insulation

As a homeowner, when you choose Spray Foam insulation, it is important to know what options are available. Deciding on the right material that meets your needs can help you save and cut back on AC dependency. There are two types of Spray foam insulation: Closed Cell and open cell.

Open Cell Insulation

This is a rubber-like material. Made by incorporating sodium bicarbonate, this happens during the manufacturing process. Since its rubber-like, the insulation expands once installed. The reason why its classified as open cells is that over 50% of its cells are open.

Due to its nature, the material acts as like a spring. What this means is that if compressed, the material can regain its original shape in minutes. The reason this happens is because of unrestricted air movement. Another reason why the material acts this way is due to its chemical makeup. As such, it can conform to the shape of any location its applied.

Closed Cell foam

Unlike open cell foam where most of the cells are open, closed cell foam has its cells enclosed. The cells are not interconnected. This means it does not possess the same “spring-like” properties as open cell foam.

Closed cell foam is manufactured by incorporating a gas on a rubber compound. The gas of choice is normally nitrogen. This is applied at high pressure compressing the insulation into a compact material. Closed foam can also be manufactured by add gas forming materials into the rubber compound.

As a result of subjecting the material under high pressure, the end product can vary in density. You can have soft or hard insulation. This material is suitable for insulating homes thus reducing the movement of heat. It is also ideal for industries where liquid resistance is of importance. Such industries include the automotive and HVAC.

Open cell vs Closed-cell foam

A lot of homeowners don’t realize that open and closed cell insulation’s have differences. This is despite being classified as Spray foam insulation. One notable difference is the cells. For open cell foam, the cells are not enclosed and not interconnected. Closed cell foam has enclosed cells. This means that in open cell foam, air fills the spaces. As such, the foam insulation has a soft or sponge-like appearance. Due to this, contractors use less material when insulating your home.

The R-value of open cell foam is 3.8 per inch while closed cell foam has an R-value of 6.5 per inch. What this tells you is that closed cell foam insulation is more efficient than open cell. This makes it ideal for use in areas with limited space for insulation. As a result of the high R-value, closed cell foam strengthens the structure its applied to while open cell foam does not.

Compared to open cell foam insulation, closed cell foam insulation is resistant to moisture transfer. This prevents common moisture problems such as mold infestation. When it comes to cost, open cell foam is more expensive per board foot. However, the lower R-value diminishes the savings. Spray foam insulation application is different to cellulose insulation application.

Advantages of Spray foam insulation

As said earlier, Spray Foam insulation is the future of insulation. So, if you choose to have it installed, these are the benefits you will enjoy.

  • Reduce heat loss – spray foam insulation seals all gaps in your home thus reducing movement of heat. This eliminates the need to run your AC.
  • Easy to apply – spray foam insulation is easy to apply, unlike pink fiberglass. This makes it ideal for residential and commercial applications.
  • Financial savings – once you insulate your home, you cut back on electricity use. As such, your electricity bills will be much lower.
  • Lower heating and cooling costs -spray foam insulation does not deteriorate. This means your home gets protection for a long time.
  • Noise level reduction – insulation seals your home making it airtight. As a result, it reduces sound infiltration into your home assuring you of peace of mind.
  • Reduces airborne particles – this improves the health of your family. The reason for this is that allergens will not be present in your home.
  • Reduce the impact of Global warming and climate change.

Disadvantages of Spray foam insulation

Although Spray foam insulation has several advantages, there are a few drawbacks you need to know. They include:

  • Best installed in newly constructed walls
  • Its messy especially during installation
  • Although DIY kits are sold, it’s highly recommended to hire professionals
  • Unlike traditional roof insulation like roll form the spray foam is very messy.

Final Thoughts

Spray foam insulation is the ideal solution for homeowners in need of sealing their homes and making them airtight. Although one has to deal with the cost and off-gassing effects, the long term benefits outweigh cons.
