Frequently Asked Questions
Q: What is D-Blaze?
A: D-Blaze Fire Retardant Treated (FRT) wood is a new generation construction material for weather-protected applications.  Its extremely low hygroscopic and corrosive properties make it a superior choice for use whenever FRT wood is required.
Q: Has D-Blaze been high-temperature tested?
A: Yes, D-Blaze lumber has been tested per industry standards at 80° F and 150° F at 75% relative humidity. D-Blaze plywood has been tested at 170° F and 90% relative humidity.
Q: Has D-Blaze ever had a structural failure?
A: D-Blaze has never had structural or any other kind of failure. Due to its excellent performance in the market place and in accelerated exposure testing, D-Blaze has never required a formulation change.
Q: Does D-Blaze have a warranty?
A: Yes! D-Blaze material has a 50-year Limited Warranty covering "the reasonable cost of repair of that portion of the structure damaged as a direct result of the failure of D-Blaze.
Q: Does D-Blaze meet the Model Building Codes?
A: Yes! D-Blaze is approved by BOCA ES 95.42, Southern Building Code ES 9657 and Uniform Building Code ES 5180.
Q: Is D-Blaze a Type-A fire retardant?
A: Yes! D-Blaze has been tested and exceeds AWPA C20 and C27 (ASTM D3201 at 92 +/- 2 percent relative humidity).
Q: Can D-Blaze be used for roof shingles or exterior siding?
A: D-Blaze is an interior fire retardant and cannot be used when it will be exposed directly to rain or continual wetting.
Q: Can D-Blaze be glued?
A: Yes.  The material must be dry, 19% MC for lumber and 15% MC for plywood. The surfaces should be clean and free of all foreign material. A light brush or sanding may be necessary. A solvent-based contact cement works best. Water-based glues should be tested before use.
Q: Can D-Blaze be painted or stained?
A: Yes. Surfaces must be clean. A light sanding or brushing is recommended. Material must be dry. Follow paint manufacturer instructions. Use only high quality stains and paints.
Q: Does D-Blaze meet a one-hour fire rating?
A: No fire retardant treated wood meets a one-hour rating. D-Blaze studs, plywood, etc. are used in wall and roof assemblies that have one to four hour classifications. However, fire-retardant treated material itself does not qualify for an hourly rating.
Q: Can D-Blaze be milled after treatment?
A: D-Blaze has received Underwriter's Laboratories highest classification possible: "FRS" on eighteen species of lumber and four species of plywood. This classification allows light sanding, end cutting, including diagonol end cutting and boring of holes after treatment.

Once in a great while, paneling or molding requires milling after treatment.  UL has a special burn test, inspection and classification for it. Besides the burn tests, the company doing the milling after treatment must separately contract with UL. Each time a company mills after treatment, a UL inspector must be present to inspect the material before treatment and re-label the material after treatment. Due to the lack of interest and the high cost of classification, the chemical company that provides D-Blaze treatment CSI  has not tested any species for milling after treatment.  However if the demand is sufficient, CSI would seriously consider it.
Q: What if D-Blaze material gets wet during shipping or storage at the job site?
A: D-Blaze fire-retardant treated wood products are for use under continuously dry conditions.  The treated wood products are not permitted in areas exposed to weather or wetting. Exposure to precipitation during shipping, storage or installation shall be avoided. If the treated wood products do become wet, they must be replaced or permitted to dry at a maximum 19 percent moisture content (MC) for lumber and 15 percent MC for plywood prior to covering or enclosure by wall board or other construction material.
Q: Will D-Blaze stop termite and decay attack?
A: Mississippi Forest Products' Utilization Laboratory tested D-Blaze treated wood material using ASTM D3345-74 and D1413 standard test procedures.  The results of these tests showed that the D-Blaze treated material tested was effective in protecting the wood from attack of termites and decay for interior above ground use.
Q: Is D-Blaze approved by the US military?
A: Yes! D-Blaze is approved by the US military as well as use in US Government applications.
