Spray Foam 101: DIY Insulation Tips

Spray foam continues to grow as a popular method to insulate homes and commercial buildings. Additionally, there have been large increases in the availability of spray foam equipment to people for their own DIY projects. Here are a few great ways to ensure that  your insulation project goes smoothly.

Control the Temperature

Temperature is relatively easy to control during a spray foam application, depending on the spray foam equipment. However, many people mistakenly overlook the temperature of the drums/tanks in many applications.

Too Hot

For example, leaving 55-gallon spray foam drums in the sun during a summer application may produce a poor mix between the component A and B chemical. Not only are the spray foam chemicals being heated through the equipment, but the 55-gallon drums as well.

Too Cold

The same problem can happen during extreme cold temperatures. It is often wise to purchase heating bands or a heater to keep polyurethane spray foam chemical at room temperature. If the chemical is too cold, the foam may not rise properly causing a decrease in foam yield. Keeping the drums warm will ensure that the chemicals react well with one another.

Just Right

A poor mix of foam often leads to project delays. One way to solve this problem is keeping the drums/tanks in a temperature controlled environment before spraying. The ideal spray foam conditions are generally between 60 to 75 degrees Fahrenheit. Even providing some sort of shade for the drums on a hot day or a heater on a cold day will greatly reduce the chance of a poor mix.

Practice Your Technique

Another useful way to help insulating projects is proper spray foam technique. Spraying foam can sometimes be tricky due to the nature of foam itself. Foam may rise high in one spot and low in another.

Generally, you should try to spray all parts of an application evenly. The best way to do this is to keep a consistent spray foam pattern. It is best to go over an area with one coat and get a feel for how the foam is going to rise. Once that location has been sprayed, you can get a better idea of how to spray on the second coat. Following these simple steps will greatly cut down project time and ensure that foam has been evenly distributed throughout an application. Good luck on your insulation projects, and remember that with some practice you’ll be a pro in no time. Be sure to reach out if you need any equipment for your insulation projects or need some extra help.
