Looking to insulate your property? Then welcome, you’re in the right place to learn all about icynene insulation: the number 1 kickass spray foam insulation. Here we outline the pros and cons of icynene insulation and where it should be used.

What is Icynene Foam insulation?

icynene insulation

Icynene foam insulation is a type of polyurethane foam that has been specially designed for the construction industry. It’s made from recycled materials such as old tires, plastic bottles etc., so you can rest assured knowing your home or business is being built with eco-friendly products.

It’s also fire retardant which means if there was ever an emergency situation where you needed to evacuate quickly then this would help keep people safe by reducing heat loss in buildings.

The two types of spray foam are open-cell foam and closed cell foam. Open cell Icynene spray foam is more flexible than closed cell, which is rigid with a dense structure.

Icynene is an excellent insulator that has been used for many years in the construction industry. It was originally developed by DuPont as a fire retardant material. The company later sold its interest in this product to another chemical manufacturer who then marketed it as “Foamite”.

Where Should You Use Icynene Foam?

You could install Icynene foam on any building including:

• New homes

• Extensions / additions

• Renovations

• Commercial properties

Icynene spray foam insulation is great for sealing cracks and holes, but it is not recommended for walls that are less than 2 inches thick. If you want to insulate a wall that is less than 2 inches thick, then you should consider using fiberglass insulation instead.

Pros and Cons of Icynene Insulation Foam


  • Energy saving
  • Eco-friendly
  • High insulation value
  • Sound Proof
  • Quick to install
  • Creates an air barrier, preventing air leakage
  • Open-cell foam insulation is vapor permeable, which allows the passage of water vapor.
  • 100% water blown


  • Not a DIY job, it must be done by a licensed foam contractor.
  • Significant upfront costs, however these more than pay for themselves in the long term.
  • It can be messy
  • It takes longer to dry

Is Icynene Spray Foam The Best Spray Foam?

Icynene spray foam is the best spray foam because it has a high R factor, which means it insulates better than other types of spray foam. The R factor is measured by how much heat is transferred through the insulation. On the other hand, if you just need some extra warmth during the cold months, nothing beats traditional blown cellulose insulation.

How Much Does Spray Foam cost?

The 2 factors that the cost usually depends on are whether it is open cell or closed cell spray foam and the R-value. The higher the R-value, the lower the cost per sq ft. The price may vary but here we have the average cost of both variants:

Open cell spray foam $7.38 per square foot.

Closed cell spray foam $9.40 per square foot.

Is Icynene Spray Foam Insulation Worth it?

Spray foam insulation is the only type of insulation that gives your home a complete air seal that will keep your home comfortable all year round. Even during the coldest of winters spray foam insulation will keep your home comfortable because it keeps the air and heat, that you’re paying to generate, inside your home. What’s more, when you have a properly installed spray foam insulation system, you’ll never need to worry about heating bills again. It ranks highly in energy efficiency.

Your comfort, and by extent, the comfort of your family is priceless, but what you can surely put a price on is the cost of your air conditioner and your central heating running constantly. It keeps your monthly energy bills under control and reduces your carbon footprint.

If you want your home to be comfortable throughout the year, spray foam is the only material that can do it effectively as well as eco-friendly
