What is fire defense for wood framing?

A fire inhibitor sprayed onto the exposed interior lumber while the frame is open. A framed building has no sprinklers and no gypsum on the studs yet, so the spray reduces flame spread on the surfaces that would otherwise carry a fire through the structure.

Who does the spraying?

The framer you already hired. FireProShop trains the crew and sets up the equipment, so there is no new trade on your site and no added days.

What equipment do you supply?

Backpack or cart rigs sized for a crew's day, with tips and pressure set for MFB-31. The inhibitor ships ready to use in 5-gallon pails.

When in the framing sequence does the spray happen?

As the walls go vertical and before windows and mechanicals go in. Spraying before the interior is closed up is what makes the application complete.

How much product does a job take?

Spray is figured at 0.16 ounces per square foot minimum. Send the framing package and the quote comes back with the quantity, the equipment and a training date.

What documentation comes with it?

The application record for the address, alongside the ASTM E84 extended test data behind the chemistry, for the close-out package.
