Spray Foam Insulation Warming

An effective way of solving viscosity issues related to spray foam application systems



Spray foam is a popular insulation alternative to traditional building materials such as fiberglass. It is a two-component mixture (isocyanate and resin) that is stored in cylinders and applied through an applicator gun. The liquid foam material must pass through two separate tubes that come together at the tip of an applicator gun to mix and form an expanding foam spray. The mixture must be kept at and applied at a minimum temperature of 70°F (21°C). If the components cool, the spray foam becomes very difficult to extract from the cylinder and process through the delivery hose and applicator gun. This can result in slow production or even clogs within the system that can cause significant downtime


Heat the hose with XtremeFLEX® RKP silicone rubber heating tape. This super flexible heating tape is designed with a built-in pre-set thermostat that maintains heat output at 70°F (21°C). The supplemental heat ensures an optimum operating temperature is provided to assist spray foam components as they travel through delivery hoses and into an applicator gun. The RKP heating tape has a low watt-density of 6 W/ft (20 W/m) to provide safe operation and avoid overheating the chemicals. Standard lengths are available from 10 ft to 200 ft (3 m to 61 m) to meet your needs. If necessary, higher temperature, higher watt-density and custom length options are available. For added protection and efficiency, wrap the hose and heater assembly with an insulated abrasion resistant cover. This solution eliminates downtime and extends the service life of your spray foam equipment.

Protect the cylinder or barrel with a BriskHeat DHLS Drum Heater. The DHLS drum heater is adjustable up to 160°F (71°C). Both heating solutions are easily installed and “plug-and-play” ready, allowing the warmers to be plugged into a standard electrical source without special wiring.

Additional Uses

BriskHeat’s RKP long-length silicone rubber heating tapes with built-in pre-set thermostats can also be used for freeze protection on complex winding or difficult-to-install pipe applications, or on objects that have unique shapes and sizes. Custom RKP heating tapes are available.
