Everything You Need to Know About Spray Polyurethane Foam
Far from the knowledge of most people, polyurethane foam is actually very common in building and household construction work. How they are applied matters in classifying two polyurethane foam types. You have the spray foam and the rigid foam. In terms of price, spray polyurethane foam is cheaper. It is not as effective as the rigid foam. If you are wondering why there are a lot of spray polyurethane foam services in the market, here are some basic spray polyurethane foam facts worth noting. Click to learn more now about them.
Basically, polyurethane foam is a type of insulation material. It has high thermal resistance, though, because of its low-conductivity gas. This is great news though. A spray equipment must be used to apply this foam from its original liquid state. The usual gas that is used to carry out the process is hydrochlorofluorocarbon gas. The gas that will be used will have an R-value range of R-7 to R-8 that will decrease over time with the help of the thermal drift process. Once the low conductivity gas goes out of the air, gas molecules found in the air will then replace the gases in the insulation. This process often begins after two years have passed with the installation process.
Though you get more insulation from rigid polyurethane foam, applying spray polyurethane foam is much easier because it easily follows the surface form. This is one of the reasons why the application goes by the name of foamed-in application. Currently, changes have been made in the foaming agent used in spray polyurethane foam, which is non-CFC. Though non-CFC foams are less effective insulation materials, they do not pose as much threat as CFC to the ozone layer. In terms of temperature, it is still effective. For the creation of low-density foams, using carbon dioxide as a forming agent is also done.
When it comes to spraying polyurethane foam, the right equipment must be used. Furthermore, only properly trained personnel are allowed to be spraying polyurethane foam accordingly. Hiring reliable spray polyurethane foam services is a must. With the use of high-density foams, you can expect their expanding capabilities to be slow. On the other hand, low-density foams rapidly expand. This means that once you apply them to the surface of your walls, they seal in an instant. If the person is not careful in the application, overexpansion may take place. This creates damage to your wall. You should not be worrying about these consequences with the help of a good spray polyurethane foam service.
Only with proper spray polyurethane foam services can your home benefit a lot from the process. Proper insulation is what you get from the process. Your home will also be free from wind or air infiltration. What you get in return is less energy usage hence less energy expenditure.
