Spray foam insulation is a great way to create a tight, energy-efficient building envelope. It comes in several versions, each of which comes with unique benefits. Though factors like temperature and ambient moisture can alter the curing time of foam, as a general rule it will cure within 24 hours. Foam can be applied directly to sheathing and is approved for contact with most building materials but may require additional coatings, depending on location and type of foam you are using.
Let’s review the different kinds of spray foam insulation and the best use for each.
This is the least dense of the foams, and has the advantage of being the quickest to install, as it can usually be applied with a single-pass installation. If you are looking for all the benefits of a tight high-performance home, open cell is the most economical choice. Another advantage of half-pound foam due to its softer texture is its sound absorption qualities. However, it is important to note that open cell is for interior use only.
Best uses:
This is a more dense version of the half-pound providing almost twice the R-value per inch of thickness. Additionally, two-pound foam gives you added structural strength and due to its low vapor permeability it is classified as a vapor retarder and acts as a secondary bulk water barrier.
