Choosing The Right Foam: Open-Cell Spray Foam vs. Closed-Cell Spray Foam

Choosing The Right Foam: Open-Cell Spray Foam vs. Closed-Cell Spray Foam

Choosing the Right Foam for Your Portable Spray Foam Equipment

It is choosing the right type of spray foam insulation is an incredibly important decision. Companies such as ArmorThane have a wide variety of portable spray systems to choose from, which can be used to install both closed-cell and open-cell spray insulation. This gives their customers true flexibility when it comes time to perform essential tasks.
There are no differences in quality between closed and open-cell spray insulation. However, due to the different physical properties of both insulations, open-cell insulation may be the best option depending on the location where the spray foam is applied.

The foam forms “cells” as it expands and cures. Whether the air is trapped within these cells will determine if the foam can be considered an open or closed cell.

Open-Cell Spray Foam Insulation

Because it is less dense and requires less material for coverage, open-cell spray polyurethane foam is best suited to interior projects. The foam is free from gas, so it doesn’t trap gas in its cells. Instead, the foam leaves openings in its structure that allow other cells to connect and interlock. These openings are then filled with air from around the environment. Because open-cell spray foams can be porous, they don’t resist water and are therefore unsuitable for use above grade or in areas where moisture is unlikely. They do improve sound deadening and have an R-value of around 4.3 per inch.

Closed Cell Spray Foam Insulation

Closed-cell spray foam consists of tiny bubbles made of gas suspended in the process of application and curing. The propelling agent traps the gas, which adds insulation to the foam. Its typical R-value is around 6.0 Closed-cell foam can be used in both exterior and interior applications and can improve the structural strength of walls being insulated.

Closed-cell foam can also resist water and vapors due to its strength and reinforced nature. The foam’s structure makes it denser and requires more material to cover it.
