WHAT IS D-BLAZE?

D-Blaze® fire-retardant treated wood (FRTW) is highly effective at controlling the spread of flame and smoke, increasing evacuation time and potentially reducing damages and repair costs caused by fire. D-Blaze FRTW slows the combustion cycle of fire by forming a protective layer of char, hindering flame spread and smoke formation.

Tested and listed by Underwriters Laboratories® (UL® and ULC®), D-Blaze FRTW meets the requirements of construction materials as set forth in all North American building codes. During the code required 30-minute flame and smoke test; UL 723 (ASTM E84), D-Blaze FRTW shows no evidence of significant progressive combustion.

D-Blaze is recognized as a code compliant pressure-impregnated fire-retardant treatment under the International Building Code® (IBC®), International Residential Code® (IRC®) and the National Building Code of Canada® (NBC®) for lumber and plywood products used in fire rated assemblies and interior applications where fire retardant construction materials are permitted and specified by the building codes.

Structural Properties

D-Blaze FRTW has been tested by independent laboratories following industry standards ASTM D 5516 & ASTM D 5664 to develop strength reduction factors for various use conditions, including roof temperatures of up to 150° F for lumber and 170° F for plywood. Consult the Data Tables in the D-Blaze Technical Specifications Brochure for more information. Table 1 (D-Blaze Lumber Strength Design Adjustment Factors) and Table 2, 3 and 4 (D-Blaze Plywood Span Rating Adjustments) for specific adjustment factors.

How to Specify D-Blaze® FRT Lumber and Plywood

To assure structural integrity in roof areas of high temperature and humidity, D-Blaze span and strength design adjustment factors have been determined by independent third parties in accordance with ASTM D 5516 for plywood and ASTM D 5664 for lumber. Extended specifications can be found at ARCAT.com.

All D-Blaze FRT lumber and plywood:

  • shall be pressure-treated with D-Blaze® fire retardant to meet Underwriters Laboratories FR-S rating or a flame spread and smoke index rating denoting a surface-burning characteristic rating of 25 or less for flame spread and smoke developed.
  • shall bear the Underwriters Laboratories label or stamp attesting to the FR-S rating or flame spread and smoke index rating, and to the fact that it also meets the American Wood Protection Association (AWPA) P50, U1, UCFA for interior Type A (HT) use.
  • shall be kiln-dried to a maximum moisture content of 19% for lumber and 15% for plywood.
  • shall be kept dry at all times during transit, job site storage and construction.

*Note: Designer may wish to specify lower moisture content for cabinet and millwork.

All structural design calculations shall be based on the Strength Design Factor Tables as published in D-Blaze Technical Specifications brochure.

NOTABLE PROJECTS

D-Blaze FRTW has been installed in many notable projects including the new One World Trade Center in NYC, the Sears Tower and Navy Pier in Chicago.

  • Backed by a 50-Year Limited Warranty, D-Blaze FRTW is protected against structural failure due to strength loss caused by high temperature and high humidity conditions.
  • Acceptable for use in sensitive environments such as schools, healthcare facilities, hotels and multi-family construction projects, D-Blaze received GREENGUARD® Gold certification for meeting some of the world’s most comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air.
  • GREENGUARD Gold Certification Information
  • ASTM E 84: Standard Test Method for Surface Burning Characteristics of Building Materials extended for an additional 20 minutes. (30-minute test duration)
  • ASTM D 3201: Standard Test Method for Hygroscopic Properties of Fire-Retardant Wood and Wood-Based Products

D-Blaze® pressure-treated products do not contain any EPA-listed hazardous chemicals and are easy to work with, requiring no special precautions other than routine wood working safety procedures. When working with or machining D-Blaze pressure-treated wood, the following safety precautions should be followed:

  • Wear gloves to protect against splinters
  • Wear a dust mask when machining any wood to reduce the inhalation of wood dusts
  • Wear appropriate eye protection to reduce the potential for eye injury from wood particles and flying debris during machining
  • Wash thoroughly with mild soap and water after working with treated wood
  • Wood scraps should be disposed of in accordance with local waste management regulations.
