Treated Lumber

What Kind of Wood Treatments Does Forest Lumber Offer

MicroPro® technology is a revolutionary way to pressure treat wood for decks, fences, landscaping and general construction uses. MicroPro pressure treated wood is treated with micronized copper preservatives, which help protect against termite damage and fungal decay. MicroPro offers many benefits including significantly improved corrosion performance. MicroPro treated wood products are US building code compliant.

The Osmose MicroPro technology is the first treated wood process to be certified under Scientific Certification Systems Environmentally Preferable Product (EPP) program based on
Life-Cycle Assessment.


D-Blaze® fire retardant treated wood (FRTW) is available for interior applications where fire retardant construction materials are specified or required by building codes. D-Blaze treated lumber and plywood is highly effective in controlling the spread of flame and smoke development caused by fire.

D-Blaze treated products show no evidence of significant progressive combustion at 30 minutes exposure to flame. In most applications, D-Blaze treated products offer a lower in-place cost than noncombustible classified materials.

What is beneficial about our external treated lumber?

  1. Lighter “natural” color.
  2. More natural wood appearance.
  3. First Wood preservation to Receive EPP Status. The Osmose MicroPro technology is the first wood preservation to be EPP (Environmentally Preferable Product) certified by Scientific Certification Systems.
  4. Because of its lighter color – Better paint and stainability.
  5. Better corrosion protection for exterior code-approved fasterners and hardware.
  6. MicroShades – Innovative micronized pigment color choices. Pressure treated wood colors similar to redwood & cedar.
  7. End uses include interior and exterior above ground, ground contact, and fresh water immersion.
  8. Treated wood warranty programs.
  9. Approved for aluminum contact.
  10. building code compliant. ICC – ES report, ESR – 1980

D-Blaze Fire Retardant: The New Generation building Material

D-Blaze Fire Retardant Tread (FRT) wood is a new generation construction material for weather-protected applications. It’s extremely low hygroscopic and corrosive properties make it a superior choice for use whenever FRT wood is required.

D-Blaze FRT wood is non-blooming and colorless. It qualifies for use in accordance with major building codes and insurance rating bureaus.

Wood treated with D-Blaze is paintable, stainable, easy to handle and workable with common tools. In most cases, FRT wood systems have lower in-place costs than other noncombustible -classificated materials.


D-Blaze FRT wood has been tested by Under-writers Laboratories, INc. (UL) Northbrook, Illinois, and has been awarded the UL classification of “FRS” which signifies a 25 or accelerating for flame spread and smoke development. When tested for 30 minutes’ duration, there was no evidence of significant progressive combustion. Each piece of treated material bears an easily identifiable UL stamp.


Wood treated with this new, scientific formulation solves many of the problems encountered with earlier-generation fire retardant formulas, notably hygroscopicity. D-Blzze FRT wood shows very low hygroscopicity. D-Blaze FRT wood shows very low hygroscopicty under conditions of high humidity.

It meets or exceeds the hygroscopicity requirements of AWPA c-20/C-27, UC1, T1 for Type A use. In tests conducted in accordance with ASTM D-3201 at relative humidity up to 95%, it has virtually the same moisture content as untreated wood.
