Protection That Starts at the Stud

Reduce Fire Risk Before the Drywall Goes Up

Fire-retardant treated lumber protects the structure from framing through occupancy — on the job site, during construction, and for the life of the building. Nothing to spray, nothing to reapply, nothing to maintain.

The problem

Two exposures a wood-framed building carries before anyone moves in.

Both happen while the framing is still open, and both can be documented and handled then. Wood is renewable and grown across North America. The case for framing with it holds up better when these are dealt with.

Exposure 01
Moisture

Water trapped under the plates

Rain and snow land on the deck during framing and collect under the bottom plates. Once the walls are up and the drywall is on, the underside of the plate is the one surface on the job nobody can reach again.

Exposure 02
Fire

Framed, but not yet defended

No sprinklers, no gypsum on the studs, a full load of exposed lumber. Cheyenne lost a four-story apartment building under construction on May 26. Denver lost one to a five-alarm fire on January 2. Neither had anything to do with wildfire.

Documentation

A report you can hand to your risk manager.

Each layer has a test standard behind it. The lumber arrives under an evaluation report from an ANAB-accredited agency, written against the alternative materials provision building officials are required to accept. Most builders have never been shown it.
