What is the Best Way to Heat My Spray Foam?


Increase the Yield of Your Spray Foam BusinessAre you one of the thousands of spray polyurethane foam (SPF) contractors struggling to keep your SPF at the right temperature during the winter season? Are you tired of fighting a never-ending battle of cold foam that doesn’t flow properly, hot and cold spots within your drum, or overheating and frothing SPF?


You’re not alone! Many contractors are still dealing with old technology and practices which have never provided the consistent, equal heat distribution needed to supply the installer with perfect SPF at the tip of their gun. Most contractors are still using outdated, ineffective band heaters. While band heaters provide extremely high wattage, this power is only directed at a small portion of the container, which produces inconsistent, disproportionate heating of the SPF. The unpredictable turn-dial thermostats also lead to faulty temperature control and over-heated, wasted product.


Why? Why aren’t contractors demanding a new solution? Why continue to get by with “making it work?” This is no way to operate an efficient business and surely not going to provide a quality foam installation project that you want to stamp your name on.


This complication is so common, in fact, that it even demanded the attention of the authoritative organization within the industry, the Spray Polyurethane Foam Alliance.


The SPFA “is the collective voice, along with the educational and technical resource, for the spray polyurethane foam industry. Our experienced staff and member-comprised committees provide a wide variety of services to the industry.”


They produced the following tech tip: Maintaining Proper SPF Material Temperatures


“Low heat flux blanket-type heaters work well to maintain drum temperatures. Avoid use of band-type heaters or other high heat flux heaters…”
