Closed Cell vs. Open Cell

When it comes to any of your Commercial or Residential needs, we use two types of spray foam — Closed Cell and Open Cell

First, it's important to understand what R-value means. Technically speaking, R-value is defined by 'The capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.'

Closed Cell comes in a more densely compacted form, and is typically used on structures that are built with 2x4 framing. This allows us to fit more R-value into a much smaller area. Closed Cell must also be used on any concrete surface due to its internal vapor barrier, which prevents the concrete from unwanted moisture transfer. One added feature of using Closed Cell is that it helps with structural integrity, which can be increased by as much as 400%.

Open Cell is more commonly used in residential areas, typically when dealing with 2x6 framing, as it will expand to a much greater dimension, and help fill the void between wall studs. Aside from its obvious heating benefits, one advantage to this type of foam is its sound-deadening capabilities. This will include internal walls surrounding bathrooms, spaces between floor levels, and any high traffic areas — anywhere that has excess sound that you might want to restrict.

We understand there may be times where you're unsure which type of foam you might need for your specific project, so please Contact Us with any further questions you may have.
