Danger of Spray Polyurethane Foam

Spray foam insulation is a popular insulation choice for homeowners. It is easy to use and can be installed just as quickly as traditional fiberglass insulation. However, spray foam insulation does pose some environmental and health risks. When choosing a type of insulation such as spray foam insulation, consumers should be aware of such risks posed to their health and the environment before they make their choice.

Uses

There are many uses for spray polyurethane foam. It is ideal when looking to insulate small or difficult-to-reach areas such as door frames. However, it is also used to insulate large areas. Some homes are completely insulated using polyurethane foam. The polyurethane foam is applied with a gun that combines materials at its tip. When combined, these materials make an effective insulator. The purpose of any insulator is to protect a home or business from outside temperature changes.

Disadvantages

There are benefits to using spray polyurethane foam, but many agree that the disadvantages, health risks and environmental impacts far outweigh the advantages. Spray polyurethane foam is more expensive per square foot than traditional fiberglass insulation. Unlike fiberglass, foam insulation's effectiveness can decrease as it ages; the ability to insulate against changes in temperature is compromised slowly over the years.

Health Risks

Some people have allergic reactions to spray polyurethane foam. These reactions, however, are usually only brought about when a person comes in physical contact with the foam. Installers of polyurethane foam need to be protected when applying the foam to a project. Fumes can be deadly if inhaled, so respirators should always be worn. If this type of foam comes in contact with the eyes, they should be rinsed thoroughly and attended to immediately because temporary blindness can occur.

Environmental Effects

There are types of fireproof polyurethane foams on the market, but the types that are not fireproof can release toxic fumes into the air if burned. Greenhouse gases are produced by the blowing agents used to expel materials from spray foam applicators. A big concern for some people is that many spray polyurethane foams use fossil fuels in their composition. These are just a few environmental effects that come with using spray polyurethane foams. Some brands of polyurethane foam, like Eco Answers US, put in great efforts to assure consumers that their products do not have the damaging environmental effects that other brands have.

Costs

Traditionally, spray polyurethane foam can cost anywhere from $1.50 to $2.50 per square foot depending on thickness. This type of insulation can be used by itself or in a combination with fiberglass to insulate a home or business.
