The Pros and Cons of Spray Foam Insulation

Spray foam is a unique insulation and air barrier that seals the building envelope to prevent drafts, limits air infiltration and stops cold or hot air movement throughout a home. This helps reduce energy usage, lowers heating and cooling bills, eliminates odors and pollutants and increases indoor comfort.

Attic insulation speaking, there are two types of spray polyurethane foam: open and closed cell. Their differing cell structures dictate their features and physical properties. Open cell spray foam is often referred to as half-pound or low density foam and has the ability to compress. It is best for insulating walls and filling in gaps, voids and unusual framing. It also has the flexibility to fill in corners of exterior walls where air can pool and condense due to differences in temperature between outside and inside a wall.

Closed cell spray foam, on the other hand, is a thicker product that resembles a sponge. It can be used in any situation where a durable, long-lasting product is required. It is most commonly installed in new homes, pole barns, commercial structures and vans. It is highly durable and waterproof. It can be sprayed on roof joists or rim joists to stop moisture leakage, provide an R-value and increase structural integrity of the roof.

While the benefits of spray foam are many, there are some drawbacks to this type of installation. It is important to understand what the pros and cons are before considering it for your next project.
