What is Spray Foam Made of?

There are many insulating materials available that can keep your home comfortable. But none of them are quite like spray foam. This unique product has lots of merits and is probably the reason it's becoming popular in many households and businesses.

So, what is spray foam made of? How does it work? Read on and find out!

What components make up the spray foam?

The spray foam solution is a combination of isocyanate and polyol resins. These two chemicals form a polyurethane foam in a reaction.

Polyurethane has low conductivity of heat due to its complex chemical structure. It's the reason why the material works best as an insulator.

The foam mixture insulates buildings by sealing cavities and spaces along the walls. These fillings trap air which cushions against the loss of heat through conduction. The spray is often added in attics, crawl spaces, new constructions, and rim joints. It easily takes the shape of the cavity without sagging or settling even after curing.

Polyurethane has been in use for insulation since the 70s. It, thus, has a history of quality, reliability, and success.

Spray foam comes in two forms; open-cell foam and closed-cell foam. Each has unique properties and benefits that make it useful in different applications.

Open-cell foam

Open-cell spray foam is a lighter and more pliable form of polyurethane. It has more comprehensive expansion limits than closed-cell spray foam. Hence, an excellent sound barrier and is more flexible in structure.

Open-cell spray foam is more affordable compared to closed-cell spray foam. In addition, it offers insulation and soundproofing benefits. These properties make it ideal in areas with high noise pollution. Think of industrial zones and buildings neighbouring the highways.

Closed-cell spray foam

Closed-cell spray foam is heavier, denser, and thicker than open-cell polyurethane. Its high density offers a better R-value compared to the open-cell foam alternative. The R-value is the resistance of insulation material to heat flow. Due to its low expansion capabilities, closed-cell foam is also an excellent option for smaller structures such as sheds and cargo vans. (​1)

Why should you use the spray foam?

• Reduce Energy Bills. With extreme weather changes, you may be glaring at the prospect of huge energy bills. This often results from inefficient heating systems. Having your Florida house insulated against temperature extremes is, thus, a wise call.
  
  
• Prevent Drafts. Air currents travel through structural spaces such as crevices, vents, and wiring ducts. These movements bring about undesired temperature transfer through conduction and convection. 
  
  

To prevent such heat loss, you need a material that can efficiently fill all the spaces. And this is where spray foam comes in! It quickly expands and fills even the tiniest of spaces.
​

• Prevent Moisture Condensation. The insulation also prevents moisture condensation on the walls of your house. Condensation may occur when the external and internal temperature difference is high. It may lead to moisture buildup, fungal growth, and dampening walls and floors. 

Don't let your energy bills give you sleepless nights. Protect your home against the changing seasons by insulating it with spray foam.
