Spray Foam Rig Guide is a free educational resource built for contractors who are researching, buying, or operating spray polyurethane foam equipment. Whether you're comparing your first rig or troubleshooting a machine you've owned for years, this site is designed to give you clear, technical, no-fluff information.

The spray foam equipment market is full of marketing language and vague specs. Most product pages tell you what a machine is called — not how it performs, what it requires to operate correctly, or what it will cost you to run. Spray Foam Rig Guide exists to fill that gap with real information: generator sizing, hose matching, heater wattage, air system design, safety requirements, yield calculations, and ROI modeling.

The Knowledge Center contains over 60 technical articles covering spray foam rig fundamentals, buying guides, rig engineering, equipment pricing, contractor business topics, and spray foam insulation fundamentals. Articles are written at a level that serves both new contractors evaluating their first rig and experienced operators looking to understand their equipment more deeply.

The site also includes interactive tools — a yield and material estimator, an ROI calculator, a supply calculator, and a rig comparison tool — designed to help contractors make data-driven purchasing and bidding decisions.

Spray Foam Rig Guide is published by Spray Foam Buyer Guide, connecting contractors with authorized distributors for Graco, PMC, and Gusmer based in Canton, Ohio. The educational content on this site is written to be useful to any contractor regardless of where they buy their equipment.
