Polyurethane foam is one of the most commonly used construction materials on the market today. Due to its versatility and many desirable properties, polyurethane foam is used for a wide variety of purposes and in many different products.

No matter what industry you are a part of, you might end up working with polyurethane foam at some point in some capacity, so it is important to know what it is and how it is best used, as well as when the best times are to use it. Let’s take a look at the advantages and disadvantages of using polyurethane foam.

What Is Polyurethane Foam?

Polyurethane foam is an umbrella term that describes two types of foam, rigid polyurethane foam and flexible polyurethane foam. Rigid polyurethane foam is also known as closed-cell polyurethane foam and flexible polyurethane foam is also known as closed-cell polyurethane foam.

Benefits of Polyurethane Foam

Polyurethane foam is one of the most commonly used materials for insulating homes, buildings, and other structures. There are many reasons why polyurethane foam is the best choice for insulating buildings.

Simple To Use

First and foremost, polyurethane foam is extremely easy to use. You don’t need to be an expert in insulation to apply polyurethane foam; in fact, any DIYer should be able to apply polyurethane foam at home with a little dedication. All you’ll need to do to apply most types of spray polyurethane foam insulation is grab a foam gun and apply it carefully to the areas that need to be insulated.

Watertight And Airtight Seals

One advantage of polyurethane foam spray insulation is that it can form watertight and airtight seals, allowing for more durable structures and truly seamless insulation. Rigid polyurethane foam insulation creates strong, airtight barriers, which makes it the perfect choice for home insulation and for sealing windows and doors. Good home insulation like polyurethane spray foam has a high R-value, which means that it minimizes heat transfer (and your energy bills!) while maximizing your comfort.

Resistance To The Elements

Polyurethane foam is highly resistant to the elements, meaning that it can be used both outdoors and indoors and will hold up against moisture. Polyurethane is mold-resistant, too, so you don’t need to worry about keeping it dry or growing mildew if you don’t. Many other types of insulation materials are not mold and mildew-resistant, so this is one area where polyurethane foam stands out.

Versatility

Because of the wide range of benefits to using polyurethane foam, as well as its versatility, polyurethane foam sees a wide range of applications even outside of the insulation. For example, polyurethane foam is used to make kitchen sponges, and it is also a component in memory foam, which is used to make car seats, mattresses, pillows, and many more products.

Cons of Polyurethane Foam

Polyurethane foam is one of the best insulators for buildings available on the market, and its many benefits are why it is so commonly used in construction today. While polyurethane foam has a wide range of advantages, there are a few factors you might want to consider before purchasing some for your own projects. Here’s a quick overview of the disadvantage of PUR.

Odor

Polyurethane spray foam is made of polyurethane, which tends to emit odors. When polyurethane is combined with flame retardants and other chemicals to make petroleum foam, this can worsen the odor of the polyurethane. Generally, the smell is not extremely noticeable, and only those who work for prolonged periods of time with polyurethane foam need to take protective measures to prevent potential illness.

Durability

High-quality polyurethane foam is highly durable and will last for a long period of time. That said, if you choose to buy a low-end, cheap polyurethane foam product, you might find that your polyurethane foam wears out more quickly than you hoped. Open-cell polyurethane foam is less durable than closed-cell foam, so it is best to opt for a closed-cell, rigid foam if you value durability.
