      Trustindex verifies that the original source of the review is Google. I would have to say after buying a few rigs from them whenever I try to reach my reps Hannah or Savannah they answer almost every single time or call me back in minutes. The techs are hard sometimes to get ahold of but when I call the girls they get me the help I need asap. I get all experiences aren’t the same but they have been nothing but great for me. I ask for help, I get it I call for part, it’s sent out and delivered That’s all I think most people would ask for.

     Trustindex verifies that the original source of the review is Google. There's no other company better with customer service. We have been buying parts and supplies from Spray systems for over 5 years. We have a  specialized compressor on our rig that went bad and couldn't find the model  anywhere in stock. Not only did Spray Foam Systems, Natasha and Collin have it in stock they assisted getting it to me that day 800 miles from their shop. They got on the phones and arranged transportation and we installed it the next morning. We always book up during the summer and Spray foam systems saved us. We  would advise anyone when buying a spray foam rig or just buying parts to consider the most important detail there is, "CUSTOMER SERVICE". Without it the Rig isn't worth a penny. Nevertheless if you are considering doing business with any company in the industry Spray Foam Systems take's their business seriously. Thank you Natasha and Collin.

Frequently Asked Questions

What is spray foam insulation?

Spray Polyurethane Foam (SPF) is a spray applied plastic that provides insulation while providing an air and moisture barrier for roofs, attics, crawlspaces, walls and basements. Spray Foam is a two-component foam that includes an “A” side of isocyanate and a “B” side of Resin and when combined creates a chemical reaction to make foam. After the chemicals are mixed by a trained professional, the foam is dispensed through professional equipment at high heat as a liquid and expands as it sprayed on to a substrate filling any cracks, gaps and voids. Spray Foam Insulation comes in the form of open and closed cell foams. Open cell foam is a light density half pound foam, that can expand up to 100 times when sprayed and has a sponge like texture. Most open cell foam applications are used in the interior of buildings and provide noise-reduction. Closed cell foam is a medium to high density 2 pound foam that is air and water impermeable. Closed cell foam is used for interior building applications, exterior building applications lifting and has a ridged like texture.

What equipment do you need to run a spray foam insulation rig?

A power source (generator or shore power), a proportioner, a compressor, an air dryer, transfer pumps, a hose and guns. These are main components, but further customizations are available, and our sales representatives will help you find the best equipment for your spraying needs.
