D-Blaze® FAQs

• Where can I find LEED Information on D-Blaze®?

  All product and technical information pertinent to the Viance chemicals is available for download on the Product Information page. The chemicals in D-Blaze® are free of VOCs and formaldehyde, and Viance provides a letter affirming that fact on the same page. The wood and lumber products that are treated with D-Blaze® come from various sawmills and wood treaters, so additional information on the lumber products must come from the actual lumber suppliers of the materials used in the project.

• Where can I find sustainable forestry information on D-Blaze® or other Viance treatments?

  All product and technical information pertinent to the Viance chemicals used to treat wood is available for download on the Product Information page. Sustainable forestry programs such as FSC or SFI are managed entirely by the companies that procure and resell wood through their distribution networks. All FSC/SFI information would be provided by these lumber suppliers.

• Where should D-Blaze® be used?

  D-Blaze® fire retardant treated wood (FRTW) is designed for above ground use that is 100% sheltered from precipitation and direct wetting. D-Blaze® FRTW is suitable for applications where fire retardant construction materials are specified or required by building codes.

• Where can I download specifications for D-Blaze®?

  ICC ES - ESR-2645 for D-Blaze® FRTW applies, and D-Blaze® also meets the American Wood Protection Association (AWPA) standards P50, U1, UFCA for interior Type A (HT) use. Three-part editable specifications are available here and at www.ARCAT.com and www.SpexPlus.net.

• Can I apply a paint or stain to my D-Blaze® treated wood?

  No. We do not recommend this because it could compromise the performance of the D-Blaze® in terms of flame spread rating and smoke generation should a fire occur.

• What is covered by the D-Blaze® 50-year warranty?

  The D-Blaze® 50-year warranty covers structural failure caused by a reduction in strength below the recommended design application values of D-Blaze® treated wood products due to exposure to roof temperatures of 150° F (lumber) and 170° F (plywood).

• Does D-Blaze® contain urea or formaldehyde?

  No. D-Blaze® does not contain urea or formaldehyde as an active ingredient or inert component.

• Does D-Blaze® contain any volatile organic compounds (VOC)?

  No. D-Blaze® does not contain any volatile organic compounds.

• What if D-Blaze® FRTW is exposed to rain on the job site?

  D-Blaze® FRTW should be kept dry during transit, storage and while on the job site. If D-Blaze® gets wet, then the performance properties of the treatment may suffer. Since the degree of rain exposure would vary in every case, if D-Blaze® gets wet during transit, storage or on the job site, then the D-Blaze® FRTW must always be dried to original specifications before being covered or enclosed.

• What nails or bolts should I use with D-Blaze® FRTW?

  National and local building codes change frequently. Viance recommends that local building codes always be consulted for lists of currently approved fasteners and fastener systems. Currently, hot-dipped galvanized steel or stainless steel fasteners are recommended.

• Does D-Blaze® treatment affect the strength of the wood?

  Yes. D-Blaze® FRTW has been tested by independent laboratories following industry standards ASTM 5516 & ASTM 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. Specifiers, architects and designers should consult and adhere to the Strength Design Adjust Factors and Span Ratings published in the current D-Blaze® product literature.

• Is D-Blaze® FRTW recognized by national and local building codes?

  Yes. D-Blaze® is approved by national and local building authorities. Consult current D-Blaze® product literature and ICC ESR-2645 for the latest details.

• What other testing and approvals apply to D-Blaze®?

  Visit the D-Blaze® product page for the latest list of Testing and Approvals.

• Can D-Blaze® FRTW be cut or surfaced after treatment?

  Cutting to length, drilling, and diagonal cuts, as well as light sanding, are permitted. Exposed areas are not required to be field coated. Ripping dimensional lumber is not allowed.
