Everything You Need to Know About Spray Polyurethane Foam

Polyurethane foam is utilized across building and household construction projects. There are basically two types of polyurethane foam that you can choose from depending on how they are applied. These two are spray foam and rigid foam. Among the two, spray polyurethane foam is cheaper. Only that this type of foam is not as effective as the rigid type. For those who are interested in getting spray polyurethane foam services, here is everything you need to know about spray polyurethane foam first. You can find out more now about them.

What makes polyurethane foam popular will be its insulation property. With the presence of low-conductivity gas, it has high thermal resistance. This is actually a good thing about this kind of foam. A spray equipment must be used to apply this foam from its original liquid state. The gases that are typically used in the process are hydrochlorofluorocarbons. Their R-value range of R-7 to R-8 for every inch will deteriorate in time because of the thermal drift process. You can expect the gases in the insulation to be replaced with gas molecules found in the air after escape of low conductivity gas takes place. This process often begins after two years have passed with the installation process.

While rigid polyurethane foam offers more insulation properties, application-wise, spray polyurethane foam is much easier as it follows the form of the surface. That is why the process is also referred to as foamed-in application. There has been a recent change in the foaming agent utilized in spray polyurethane foam and it does not involve any CFC gases anymore. Even if non-CFC foams are less effective at insulating, they are not as threatening 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. In addition, personnel who are in charge to do the spraying should receive proper training. As much as possible, you should only acquire spray polyurethane foam services from the right company. For high-density foams, they often expand slowly. 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. There will be overexpansion when the person has no experience in the process. This often results in your walls getting damage. These are far from your concern when you are able to get quality spray polyurethane foam services.

Your home can benefit from the proper use of spray polyurethane foam services. The most common benefit is proper insulation. Wind or air infiltration will also be eliminated from your home. What you get in return is less energy usage hence less energy expenditure.
