Frequently Asked Questions

Can a wood frame be fire rated?

A wood frame may be fire rated when it is part of a tested and listed door-and-frame assembly that satisfies the applicable building-code requirements. The rating applies to the complete assembly, including the door, frame, hardware, glazing, and installation conditions—not simply the frame material. For projects requiring documented fire performance, confirm the specified listing and installation requirements with the authority having jurisdiction.
