Spray foam insulation has become increasingly popular in both residential and commercial construction due to its effectiveness at sealing leaks and insulating homes and buildings. However, there are two distinct types of spray foam insulation, so it’s important to know the differences so you can choose the right product for your needs. Closed cell foam Closed cell foam is known for its density and moisture resistance, which makes it an excellent choice for areas prone to moisture like kitchens and basements. This type of foam is more rigid and provides a higher R-value per inch, which means it offers superior insulation compared to other materials. Open cell foam Open cell foam is softer and less dense than closed cell foam, so it’s ideal for applications where moisture isn’t a concern (attics, walls, under floors). Open cell foam is particularly effective at soundproofing and offers excellent air sealing properties, making it a good choice for interior applications where noise reduction is desired. Ultimately, you should base your decision on factors like climate, building design and your specific insulation needs. Closed cell foam is more expensive, but it offers higher durability and moisture resistance, making it suitable for a broader range of applications. Open cell foam is cost-effective and excellent for indoor applications where insulation and soundproofing are priorities. If you’re having trouble deciding, consult an insulation contractor—they’ll make an assessment based on your location, the structure of your building and your overall insulation goals.
