Step 1: Choosing the Spray Rig Size

Mobile spray rigs for the SPF insulation industry are generally configured in bumper-pull trailers, gooseneck trailers or commercial box trucks. 

The type of application typically determines the size of spray rig chosen. For example, commercial insulation or roofing projects are generally larger than residential insulation projects and therefore require a larger trailer or box truck for additional material storage. It is common to spray 3 or more sets of foam per day in these types of applications. 

Spray foam insulation projects normally require less than 3 sets of foam materials to be stored inside of the mobile spray rig. It is uncommon to spray more than 2 sets of product in a single day due to tighter workspaces and less trigger time while maneuvering from room to room or through attics and crawlspaces.
