Frequently Asked Questions

We still believe in personally answering the phone. In fact, when you call our toll-free number during business hours, you’ll speak directly to a live person who is knowledgeable about our products and processes. From our CEO to our managers and employees, Flame Stop® personnel have all witnessed fire tests and understand building and NFPA codes and standards. We frequently work with building officials and fire marshals, answering questions and providing test reports.

No. Since it’s invention, Flame Stop® fire-retardant and firestop products have never been toxic. While formaldehyde might be considered non-toxic at very low levels, it remains as being a known carcinogen and we will not use it. We believe fire and flame retardants that contain toxic chemicals give the industry a bad name.

No. Different materials require different products. For example, would you apply a latex-based paint to fabric? Our expertise allows us to always recommend the right Flame Stop® product for your specific needs.

With most applications, you can fire retard the material yourself—as long as you closely follow the application instructions. However, some locations require installers to be licensed, such as the State of California and New York City. Because our products are non-toxic and odorless, you can use a garden sprayer or an airless paint sprayer to apply our liquid fire retardants. Also, since most of our products are penetrants, you don’t have to check a mil thickness.

When it comes to fabric, the only way to truly know whether the product was applied correctly is to perform the NFPA 705 field test after the application. This test utilizes a kitchen match, kitchen tongs, and a small swatch of the fabric, and accurately indicates sufficient saturation.
