Frequently Asked Questions

How does spray foam work?

In a nutshell, spray foam insulation uses pressurized air to create an insulating barrier that can reduce energy costs in your home by up to 50%. Spraying the compressed air against the surface of the membrane on the wall or ceiling makes a continuous seal. This protects the building from moisture (closed-cell) and cold-weather damage while also stopping drafts.

Is it possible to rent the spray polyurethane foam equipment and install it yourself?

While it is possible for a building owner to rent the equipment and install spray polyurethane foam himself, this is not typically done. In most cases, contractors are hired to do this work. This is because spray polyurethane foam needs to be used by someone who knows how to do it right so that the finished product meets all of the requirements. Hiring a contractor also makes sure that your project will be done on time and on budget.

How long does spray foam insulation last?

Homes and businesses need insulation that can stand up to both cold, wet winters and hot, dry summers. It is for this reason that spray foam insulation is a popular choice among property owners in South Carolina. Most spray foam insulation lasts about 80 years, but closed-cell spray foam lasts a little bit longer.

How does spray foam insulation save me money?

When it comes to energy conservation, one of the most popular ways to save money is by retrofitting your home with spray foam insulation. This type of insulation is made up of small balloons that are filled with a water and powder mixture before being released into the air. When the balloons come in contact with warm air and pressure, they quickly grow in size, making an insulating barrier that keeps heat from escaping or getting in.

When compared to traditional insulation, foam insulation is the only type that can seal all the air leaks in the whole house.

Is spray foam a green product?

Spray foam is more cost-effective over time and less harmful to the environment than fiber insulations like fiberglass or cellulose. At first glance, other insulation systems may seem to be less expensive, but once you understand how R-values and air barriers can affect your monthly energy savings, you'll see that spray foam insulation is far more energy efficient. The use of smaller HVAC units to provide the same level of comfort when heating or cooling residential or commercial buildings also has the benefit of saving homeowners and builders money on equipment costs.

What is the R-value of spray foam insulation? 

The R-value of spray foam with closed cells is approximately 7.0 per inch (R-7), whereas the R-value of spray foam with open cells is approximately 3.7. You should think of these R-values as rough averages. Every SPF product will vary depending on its formulation.

I am having a house built. Should I insulate with spray foam? 

There is no one-size-fits-all answer to this question, as the best decision may depend on your specific circumstances. However, if you are planning on using spray foam insulation in your home, it is important to consult with a professional installer who can help you choose the right type of insulation for your project.

Spray foam insulation is made by mixing liquid polyurethane and water to make a thin, insulating layer that is light and easy to install. It has been shown to be a good way to save money on energy costs and keep the house warm in the winter and cool in the summer. 

Is it possible for you to remain in the home while spray foam is installed?

To allow the spray foam to fully cure and off-gas, different spray foam manufacturers and installers may ask homeowners to vacate their homes for anywhere between 24 and 72 hours.

What parts of my house can I insulate with spray foam?

The attic, exterior walls, overhangs, crawl space(s), and interior walls (soundproofing open-cell insulation) are the best places to improve the comfort and energy efficiency of your home.

Does spray foam insulation prevent pests? 

Spray foam insulation does help prevent rodents and mice from entering your home because it seals all the little cracks and crevices in your home.
