What Is Spray Foam Insulation Made From?

Are you looking for an efficient, cost-effective way to insulate your home or commercial building? If yes, you've most likely researched insulation materials and encountered spray foam insulation (SPF). 

SPF is among the top sought-after insulating materials for many reasons. But what is spray foam insulation made from? As insulation experts, we'll briefly discuss the composition of SPF here.

What is Spray Foam Insulation Made of?

Spray foam insulation consists of two main liquid chemicals: isocyanate and polyol resins. The two react and combine to form a polyurethane foam that expands to create a solid layer of insulation.

The polyurethane, a polymer, is the main component of SPF. It forms an essential part of insulation and gives the spray foam its desirable properties. For example, it is stable and does not react further after curing, making it a long-lasting insulator.

It also performs well against harsh elements such as heavy rains and extreme temperatures. Additionally, polyurethane does not soak water, making it the perfect insulator for preventing microbes.

How Is Spray Foam Made?

The two chemicals, isocyanate, and polyol resins, come in different storage tanks. They are then pumped through heated hoses and only mix at the spray gun nozzle, where they react.

The reaction forms an expanding foam that sticks to surfaces. This polyurethane foam fills cracks, gaps, and spaces and provides a seamless insulation layer. With a professional team, the application process should only take a few hours.

Types of Spray Foam Insulation

There are two types of SPF: open-cell and closed-cell. Depending on your insulation needs and budget, you can opt for either. Here's a brief description of each type:

• Open-Cell Spray Foam - Contains tiny cells that are not entirely encapsulated. This type of SPF is soft and flexible, making it ideal for insulating irregular shapes and hard-to-reach areas. It is also more affordable than closed-cell spray foam insulation.
  
  
• Closed-Cell Spray Foam - Contains tightly packed cells, closed off from each other. It is denser, stronger, and provides a higher R-value (thermal resistance) in comparison. It is the preferred choice for insulating exterior walls, roofs, and basements.
