What is Spray Polyurethane Foam?

Polyurethane Spray Foam, or more commonly referred to as, SPF is a high-quality insulation material used in homes and buildings. It is labeled as health-friendly and offers high efficiency. It was invented back in the 1900s and since, has been an integral part of the insulation industry. Furniture, mattresses, autos, aero planes, clothing, shoes, athletic and camping equipment all include polyurethane. Refrigerators, freezers, coolers, and hot water heaters are also insulated with this chemical.

Benefits of Polyurethane Coating

Spray foam insulation is a great way to increase efficiency since it fills in undetectable cracks and crevices to create a tight seal that keeps unconditioned air out and conditioned air in. SPF is one of the most effective thermal insulators currently available.

Polyurethane foam’s thermal and air-sealing properties are directly responsible for reducing energy expenditures. Closed-cell SPF, a denser variant of the material, can be used as a water vapor retarder, water-resistant insulation, and secondary water barrier in addition to providing structural enhancement. It can be used as insulation on the inside of walls as well as along outside walls.

Types of Spray Foam

SPF insulation comes in two varieties, both of which can be used in different climatic conditions. Open-cell spray foam is commonly used in attics whereas closed-cell spray foam comes with double the R-value than open-cell spray foam, used with the same thickness. Closed-cell foam can also strengthen the walls and roofs by acting as a vapor barrier and providing water resistance.

Use of Equipment

Producing a great combination of polyurethane foam requires the right mix of heat, pressure and spray gun configuration. Getting improper foam froth would mean some serious health issues and diseases. Spray foam systems are made to be blended at a 1:1 volume ratio (within 2 percent). On the other hand, the reactor ensures that both the “A” and “B” components are fed to the spray cannon in the same ratio.

Spray foam proportioners are made by a number of different companies. Some are powered by air, while others are powered by electricity or hydraulics. A mixture of your requirements and the machine’s output capability will determine the solution you choose.

Spray Foam Application

Keep in mind that some manufacturers claim to have “high-rise” foam that allows you to install their product easily. Who wouldn’t want to reduce their working hours? – Well, there are numerous elements to examine, before a contractor can decide whether or not high-rise closed-cell foam is a viable option. Make sure you know exactly what you’re doing and how to do it because a fire started by foam will put your project behind schedule and over budget. To the untrained eye, spraying unpleasant foam may not be immediately noticeable.

Potential Chemical exposures to spray Polyurethane Foam.


Using polyurethane foam is a great way to keep the house insulated from cold. It is used as a cushioning agent for furniture, bedding, automotive interiors along with various other applications. The polyurethane foam comes in two different varieties; closed cell spray foam and open cell spray foam. This foam is long-lasting and provides high amounts of comfort and safety, provided it is made in the right mix.
