What are the benefits of block foam insulation?

Block foam insulation is a thermal barrier for blowing with either EPS or polyiso. It provides supreme R values as well as lower U-values and differentiates models by filling interim gaps and cavities that exist between walls and through floors.

A big advantage to block foam insulation is that it does not require any additional pressure on the structure of the home, such as might be required by fiberglass batt insulation. It also doesn't require follow up time to ensure it has installed correctly since there is no possibility of voids or misalignments happening for this type of installation.

It's important to use only one type of insulation at a time--either EPS or polyiso--due to their significant differences in density, weight , and type of blowing agent. This is because the densities of these two types of insulation, EPS and polyiso, are very similar; they cannot simply be combined without causing trouble with weight loads. Also, since insulating foam can consist of materials like fiberglass for either EPS or urethane for polyiso (which do not play well together), it's important to use only one type of insulation at a time.

Fast and easy

Another advantage of block foam insulation is that the installation process is fast and easy. It also provides better coverage than batts since there are no gaps or seams for heat transfer to occur through, which results in lower temperature loss as well as higher thermal performance with block foam.

As with any insulation, it is important to note that block foam insulation does not improve indoor air quality. While the idea of this type of insulation is to prevent drafts and keep in heat, block foam itself actually prevents airflow between spaces, which can lead to mold growth if the building is moisture-prone or prone to leaks. If you have a building that is moisture-prone, block foam will actually work against you because there isn't any air flow to protect from mold growth.

Downsides to blown in insulation

In addition, while the properties of insulating foam are great for reducing drafts and improving thermal performance, there can be a few downsides depending on what type of application it's being used in. For instance, it's not a good idea to use block foam insulation on the exterior of any home. This is because it will up the R value which means reduced air flow and increased penetration from outside elements such as rain or ice on the roof.

In conclusion, while there are definitely benefits to using insulating foam, there can also be negative consequences.
