Rigid Boards vs. Spray Foam: Which Insulation Should You Use?
Rigid foam boards are a cheap and popular insulation choice for many homeowners. Spray Foam is often the better option, but spray foam can be expensive. Before deciding what type of insulation to use, you need to know all the facts. This blog post will help you compare rigid boards vs. spray foam so that you can make an informed decision about which one best fits your needs!
Similarities Between Spray Foam And Rigid Foam Boards
Spray foam and rigid boards are both made of polyurethane, but spray foam is a better air sealant.
Spray foam and rigid boards both have an R-value of about 11. But spray foam insulation has a slightly higher R-value than rigid board insulation. This means that the spray will insulate your home much more efficiently.
Advantages of Rigid Boards over Spray Foam:
– Rigid boards are cheaper
– Spray foam is tough to install, especially in open frames
– Spray foam takes longer to dry and cure than rigid boards
– Rigid boards can make your walls stronger when installed
– Spray foam is much more expensive than rigid boards, but spray foam has an added long-term advantage of being less likely to settle over time.
Advantages of Spray Foam over Rigid Boards:
– Spray foam has a higher R-value than standard insulation board;
– Spray foams create an airtight space that cannot be penetrated by air;
– Spray foam is easier to install than rigid boards and can fill open frames.
– Spray foam can better plug gaps you might have in your walls
– Spray foam also lasts longer than rigid board because it does not break
– Rigid boards can only fill surface gaps, unlike spray foams’ ability to insulate empty spaces like open walls or the basement.
– Rigid boards also cost less, but spray foam is worth the investment as it provides a more permanent air seal and insulation that lasts longer than rigid board solutions.
Spray Foam Best Uses:
Spray foam should be used for new constructions because it has an R-value of about 15 per inch. The best spray foams also create an airtight system; this airtightness makes spray foam great at getting rid of those drafts and cold spots. Spray Foam is often the type of insulation recommended by energy efficiency experts for new construction.
Spray foam should also be used in homes with open walls where insulation can fill the space – this is especially true if you live in a colder climate or your home has drafts and cold spots.
Spray foam is best for insulating basement ceilings to eliminate any condensation on the beams or walls. It should also be used if you live in an old house and want to reduce the air leaks that keep your heating bills higher than they need to be.
Rigid Boards Best Uses
Rigid boards are best for a few different reasons. For starters, spray foam can be expensive and rigid boards are more affordable. Also, spray insulation is not always the most effective means of air sealing because it cannot fill in those gaps that might exist between framing members or wall studs. A rigid board has these qualities, making it a good choice for sealing up those leaks.
Rigid foam can be used in all places and situations where spray foam can be used. So, when spray foam is not an option because of the cost or other factors, rigid foam boards are your go-to
Rigid foams should be used in all new construction
Spray foam may create a mess or disrupt other parts of your home. In this case, rigid foam is your best option.
Which is better spray foam, or rigid insulation boards? Before making a straight conclusion on this one, we have presented you with the facts of both for your perusal.
The answer is spray foam. Rigid board insulation only has a short life span of about ten years for the most common type. On the other hand, Spray Foam can last 30-40 years with little to no maintenance and have better R values than rigid boards.
