What is Closed Cell Spray Foam Insulation?

If you’re a new homeowner looking for the best way to manage the interior temperature of your house, you’ve likely looked into a variety of cooling, heating, and insulation options. Along with the more traditional types of insulation, spray foam makes a great alternative for a variety of reasons. Here is everything you need to know about closed cell spray foam insulation. 

What is it?

Closed cell spray insulation is a type of polyurethane foam. It is a plastic-based material that is sprayed to a variety of surfaces where it then expands to fill the space. Because it is a “continuous insulation” there will be an air seal barrier, making it an incredibly efficient method of insulation, especially around pillars, poles, and in attics. 

What is it Made Of?

This type of spray foam insulation is created mostly of organic chemical compounds from petroleum extracts. It can be chemical- or water-blown. More specifically, liquid ISO and resin are combined at the site of installation from two separate containers. When they are combined, they create a foam that expands to seal any gaps or cracks in the location where it is applied. 

How Does it Work?

Closed cell spray foam insulation is generally used most often in commercial buildings and pole barns where a consistent temperature is desired. Not only does the spray foam provide temperature regulation for the structure, but it also adds strength and resistance when it hardens. And because of the air seal and hearty material, the insulation helps the building resist flooding and water damage from trapped condensation. 

What’s the Difference between Open and Closed Cell Spray Foam Insulations? 

The two types of spray foam insulation are closed and open cell. While both are excellent insulation options, one may be more suited for a situation than the other. Closed cell insulation is made to be tough and rigid upon curing. It is most useful in areas that experience flooding or excess rainwater. Open cell, on the other hand, while a very effective and durable type of insulation, is made to allow any leaks drain through. Though this sounds troublesome, it has the benefit of notifying homeowners of any repairs that might need to be done. 

Why Should I Choose Spray Foam as an Insulator?

Overall, closed cell spray foam insulation is incredibly effective for regulating indoor temperatures. Because of that, you’ll be saving a lot on the costs of heating and cooling your home during seasons of extreme temperatures. And with its air-sealing properties, you’ll be able to keep those temperatures consistent for a long time to come. Plus, the added strength that your structure will experience means less worry for you!
