Basic Spray Polyurethane Foam Facts Worth Noting

Far from the knowledge of most people, polyurethane foam is actually very common in building and household construction work. Basically, there are two kinds of polyurethane foam as classified by their way of application. Spray foam and rigid foam are these two types. Talking about price, you pay spray polyurethane foam at a much cheaper price. It is not as effective as the rigid foam. 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.

Basically, polyurethane foam is a type of insulation material. With the presence of low-conductivity gas, it has high thermal resistance. Just so you know, this is a good thing. 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. With the thermal drift process, the R-value range of R-7 to R-8 of the gas will then deteriorate. 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. You can expect this phenomenon to happen two years after installation.

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 why the entire process is referred to as foamed-in-application. In the present, the foaming agent that is used to produce spray polyurethane foam is non-CFC. 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.

A dedicated set of equipment must be utilized in ensuring that polyurethane foam is properly sprayed. In addition, personnel who are in charge to do the spraying should receive proper training. Hiring reliable spray polyurethane foam services is a must. For high-density foams, they often expand slowly. On the other hand, low-density foams rapidly expand. What this means is that after applying them to your walls’ surface, sealing takes place right there and then. If the person is not careful in the application, overexpansion may take place. Your wall, in return, becomes damaged. This can be avoided when you acquire reliable spray polyurethane foam services.

Only with proper spray polyurethane foam services can your home benefit a lot from the process. The most common benefit is proper insulation. There is also effective elimination of wind and air infiltration. This causes a decrease in the utility costs that you must pay.
