The Basics of Spray Foam Insulation That You Need to Know

Did you know that spray foam insulation has been primarily used for aircraft for a good portion of the past century? Indeed, it’s only thanks to innovation that it has been increasingly adopted in residential and commercial establishments. Nowadays, this kind of professional insulation has been growing in popularity because of the immediate and long-term benefits it is known to bring. Not to mention that it provides excellent thermal comfort in whatever building it’s used. Speaking of sprayed foam insulation, here are some things you need to know about it.

What is it?

Known as foaming insulation or sprayed insulation, it is a two-part liquid insulation material that air seals wherever it is applied. It often requires two components that are kept separate until applied at the target site by a licensed installer. At the time of the application, the two liquids travel through a heated hose to the spray gun. From there, they combine to create the foam, which then expands 40–100 times its size within seconds to fill the cavity or surface.

What are the types of sprayed insulation?

It’s important to note that in residential and commercial construction, open-cell and closed-cell spray foam are typically the ones used. The former, a low-density material, is used for interiors so it is commonly applied on the underside of roof decks, wall cavities, crawlspaces, and basement walls. This low-density foamed insulation has an open cell structure that allows moisture permeability to help with bi-directional drying (of the wall assembly) as well as moisture management. The closed-cell foam insulation, on the other hand, is often used in both exterior and interior applications. This rigid, medium-density material has a higher R-value per inch that makes it suitable for tight areas that require the highest possible R-value. And because of its renowned rigidity, closed-cell spray foams have proven capable of rejecting water in bulk, which makes it a viable material to use to make the home flood-resistant.
