Spray polyurethane foam will definitely increase the performance of you home, which makes it the optimal choice. Spray polyurethane foam guarantee the highest levels of R-value per inch, efficient air sealing, moisture management and high performance. What is more, it is one of the few products on the market that are able to claim the green building silver bullet. If you are thinking to undertake a remodeling project and want to spray on foam insulation, then it is essential that you understand how this particular material works and in which way it will benefit your home. You will immediately see why this thermal insulation type is one of the most popular ones.
Spray polyurethane foam, or SPF, is a heat-activated polymer that is typically sprayed into place. It is obtained by mixing two ingredients with the use of special equipment. The mixture is thereafter sprayed onto the surface that needs to be insulated, that is the walls of the attic or those of the basement. When the chemical reaction between the two ingredients takes place the liquid transforms into a foam, it expands and eventually hardens. But why is this thermal sealant considered superior to others? Well, SPF will fully insulate the home and protect it against air and moisture infiltration, the result being lower energy bills. The material is so efficient that it is commonly used in commercial roofing projects and industrial applications.
Open-cell and Closed-cell
There are two types of foam insulation, namely open-cell and closed-cell. Although both are made from the same materials and they work in a similar way, there are some small differences. While open-cell insulation costs less for the same thickness, but in return does not offer the same R-value as closed-cell products. In addition to this, open-cell products expand too fast and the bubbles have the tendency to burst right before the plastic sets. On the other hand, closed-cell products offers 3.6 per-inch R-value, being a great choice for humid, hot climates in different places, like under the roof sheathing or in conditioned attics.
The ease of installation
The reason why spray foam insulation is so popular is that it is relatively easy to install. To be more precise, you can insert the material into the wall cavity or simply apply it to a sloped surface. However, you may encounter some issues, such as not mixing the ingredients properly or rushing through the installation. This is why you should let a professional handle the project. When it is applied properly, the thermal insulation material is an excellent energy-efficiency tool.
