Applying Spray Foam Insulation In Cold Weather

Generally speaking, drum temperatures have to maintain material between 70-80 degrees Fahrenheit on average to keep the product in good, well-working condition. The SDS issued by the material manufacturer will provide more precise guidelines for the temperature requirements.

A drum heater will keep the material inside the barrel at a perpetual warm temperature, ensuring that it is heated at every point. 

Traditionally, contractors looking to maintain foam temperature for a reasonable price have been used. The issue with these heaters lies in that they can heat only a small portion of the drum. The result is that the heat is concentrated on a specific area of foam which makes some parts of the foam too hot while keeping the other parts too cold. Insulation blankets aren’t the most efficient drum heaters since they permit specific areas to be cooler than other areas, but cold material issues are not addressed.

Even while the material within the drum stays hot, the heated hoses help keep the material temperature controlled until it can reach the spray gun.

There are supplemental solutions that will assist in keeping your product active that include; keeping your spray hose in good condition and keeping the hose and the drum elevated off of cold floors and snow so that warm air can enter underneath. Using a drum heater to warm the foam before starting the work is essential, but slowing down the dispense rate on the gun’s nozzle can also allow the process to work more efficiently. When running a hose from your rig, it is also a good idea to only pull it through a small opening, as larger openings are an easy way to lose heat.
