Customer Top Questions & Answers

Why use this product?

If you’re spray foaming basement walls where you don’t plan to finish the basement, and your code requires a 15 minute fire barrier, this is the easiest way to meet code. You can roll it, brush it or spray it on just like any other paint.

Why is it so expensive?

It’s paint that stops fire from passing through it for 15 minutes.

How does it work?

In the event of fire touching the paint, the paint expands and keeps the fire from passing through it for 15 minutes to allow the building occupants time to escape.

Someone told me this has to go on in my attic- is that true?

Unless you plan on using your attic for living space and not putting up drywall, that is most likely not true. The 15 minute fire barrier in the case of an un-inhabited attic is the ceiling sheetrock.
