Are you ready to insulate your Roanoke, VA home? With the record-breaking cold temperatures taking over most of the east coast in the past month, there has never been a better time to insulate your home. However, choosing which method of insulation to go with can be a very confusing, complicated, and down-right overwhelming procedure. Two of the most popular methods include using polyurethane foam spray or open-cell polyurethane spray foam. These two methods are both highly effective. So that begs the question . . . what’s the difference?
Polyurethane Foam Spray Insulation
Polyurethane foam spray insulation, also known as closed-cell polyurethane foam is the top-selling insulation method at Virginia Foam and for good reason! The way this insulation is applied is through spraying plastic which causes it to expand up to 30 times its liquid volume, causing it to produce an R-value per inch of 6.4+. The insulation is formed when the plastic is sprayed because it causes the cells or bubbles to compact together to form an inert gas. One of the biggest advantages of the polyurethane foam spray insulation is that it is incredibly strong and durable, helping to prevent leakage of air or water. It also is perfect for homes located in windy, damp, or water-prone areas such as the beach. This method of insulation can be used on walls, floors, freezers, ceilings, piping, vented attics, and many other areas.
Open-Cell Polyurethane Spray Foam
Open-cell polyurethane spray foam insulation is similar to its closed-cell counterpart, but a bit cheaper. One of the biggest differences/advantages of this method of insulation is that in addition to insulating air, it can also insulate sound. It works in a way that is virtually the opposite of closed-cell polyurethane in that it bursts the bubbles to allow the air to flow through. After it has been sprayed, the open-cell polyurethane spray foam is capable of expanding up to 150 times its original liquid volume. Any excess foam is typically shaved to create a flat surface for drywall installation. It has a lower R-value than the closed-cell polyurethane foam coming in at just 3.7+ per inch. This form if insulation works best on medium rooms or recording studios in which you’d like to have extra sound-proofing. It can be used on significantly less areas than the closed-cell polyurethane foam can be. The recommended areas for usage include walls, floors, vented and unvented attics, and ceilings.
As you can see, while closed-cell polyurethane spray foam and open-cell polyurethane spray foam insulation may have similar names and a few shared characteristics, both are significantly different from one another. In order to determine which method works best for your current and future needs, consider your home’s location, makeup, and what you are looking to get from your insulation.
