Lumber & Plywood
We supply code-compliant, pressure-impregnated (aka "pressure treated") fire retardant lumber and plywood for interior and exterior applications.
Interior Fire Retardant Wood
When construction codes and/or specifications require fire retardant wood for interior applications, call American Pole and Timber.
We carry a full range of Pyro-Guard fire retardant lumber and plywood and also supply fire retardant timbers, poles, and timber trusses (see below) for interior applications. Pyro-Guard is pressure-impregnated fire retardant treated wood for dry interior applications (non-damp applications behind/inside the exterior wall envelope).
Uses for Interior Fire Retardant Lumber:
- Plywood roof sheathing
- Roof trusses
- Floor joists
- Load-bearing walls
- Floor sheathing
- Partition walls
- Interior beams
- Plywood subfloors
- Wall sheathing
- Telecomm/electrical panels
Pyro-Guard meets the flame spread requirement of all building codes which is 25 or less, as determined by Underwriters Laboratories in the extended 30 minute duration of ASTM E-84, "Standard Test Method for Surface Burning Characteristics of Building Materials."
Each piece of treated wood bears the Underwriters Laboratories Classification mark identifying it as being produced under its Classification and Follow Up Services.
Exterior Fire Retardant Wood
For exterior structures that are a specified to be fire retardant, we offer Exterior Fire-X fire retardant lumber, plywood, and timbers. Exterior Fire-X is pressure-impregnated (aka "pressure treated") that provides tested fire protection for applications directly exposed to weather or high humidity -- indoors or outdoors.
Uses for Exterior Fire Retardant Wood:
- Exterior decks
- Open-air roof systems
- Roof sheathing
Exterior Fire-X meets the flame spread requirement of all building codes which is 25 or less, as determined by Underwriters Laboratories in the extended 30 minute duration of ASTM E-84, "Standard Test Method for Surface Burning Characteristics of Building Materials." Each piece of treated wood bears the Underwriters Laboratories Classification mark identifying it as being produced under its Classification and Follow Up Services.
IMPORTANT: Pressure-Impregnated, NOT a Surface Coating
Exterior Fire-X should not be confused with fire-retardant surface coatings, because test requirements and code definitions are entirely different for each. Exterior Fire-X is pressure impregnated and carries a flame spread rating derived by Underwriters Laboratories in the 30 minute ASTM E-84 flame spread test, while coatings are sprayed, brushed or rolled on the surface and tested for only 10 minutes. Fire retardant coated wood is superficially protected at best, and it does not meet code requirements for structural uses.
Fire Retardant Timbers & Poles
American Pole & Timber is uniquely able to produce fire retardant timbers, timber trusses, poles, and other large wood products treated with Pyro-Guard or Exterior Fire-X.
Fire Retardant Timber Trusses
We produce custom timber trusses as long as 100 feet and can produce them using fire retardant components upon request. Be sure to specify where your timber trusses will be used to ensure the right fire retardant treatment is used.
Fire Retardant Beams & Poles
For commercial, industrial, or residential interior or exterior projects where exposed beams, poles, or natural columns are preferred you have the option of using fire retardant products.

FAQ's About Fire Retardant Lumber
Q: Can fire retardant lumber get wet?
A: It depends. Fire retardant lumber intended for interior use should stay dry. It is intended for interior applications and is even shipped under cover of tarps or in enclosed trailers. We also offer fire retardant lumber for exterior use, which can get wet. Water-repellent preservatives are recommended for wood used in applications directly exposed to weather.
Q: Is "regular" pressure treated wood (CCA, ACQ, MCQ, etc) fire retardant or fire resistant?
A: No. Standard pressure treated wood is generally intended for use in exterior applications or even in water. The treatment protects the wood against decay caused by organic organisms from mold to insects and marine boring organisms.
Q: Can fire retardant wood be worked normally?
A: Yes, you can cut or drill fire retardant wood like another wood without the need for special tools.
Q: Is special hardware/fasteners needed for INTERIOR fire retardant wood?
A: Per the producer: Even though testing indicates that carbon steel fasteners can be compatible with Pyro-Guard, galvanized fasteners are recommended. Pyro-Guard is safe to use with galvanized truss plates, duct work, plumbing, conduit and copper. It contains no halides, sulfates or ammonium phosphates.
Q: Is special hardware/fasteners needed for EXTERIOR fire retardant wood?
A: In general, you should use hardware or fasteners that will not rust or otherwise deteriorate due to exposure to moisture. The hardware and fasteners generally recommended are made of hot-dipped zinc coated galvanized steel, stainless steel, silicon bronze, or copper.
