Flame Retardant Beams for Additional Fire Protection

Note: Residential building codes generally do NOT require Class A fire-ratings. However, most commercial building codes do require a Class A Fire Rating for fire protection. Always check your local building codes to be sure you are using the proper construction guidelines.

Flame Seal®, a water-based, non-toxic coating, is designed to bubble when flame touches it. The bubble then acts as a buffer between the beam and the flame for fire protection.

Flame Seal® is available on our Raised Grain, Rustic and Rough Sawn beams.

The test results below are for the ASTM E84-91a test using Flame Seal®.

Flame Seal® is a Water based Non-Toxic Fire Retardant coating.

The Flame Seal® coating is meant to bubble and blister when it comes in contact with fire. This bubble acts as a buffer (wall) between the flames and our product.

 

This 3 minute burn test shows
how effective our Flame Seal® coating works.

EXAMINATION OF MATERIAL:

    The material used in this investigation was produced in a ready-to-use form under the observation of a representative of Underwriters Laboratories Inc. and was applied to the indicated test surfaces at the manufacturing location.

    The composition of the coating material is of a proprietary nature and the formula involved is on file at the Laboratories for use in the Follow-Up Service Program.

    Various chemical and physical tests were conducted on the finished material.  The results developed from these tests were employed in establishing specifications for use in the Follow-Up Service Program.

SURFACE BURNING CHARACTERISTICS TESTS:

SAMPLES
.
Substrate

        Douglas Fir  -  The test decks were a nominal 22 in. wide and 8 ft. long, composed of 1 by 4 in. tongue-and-groove Douglas fir flooring fastened together on the unexposed surface with wood furring strips.  Three such decks were butted together end to end to form the 24 ft. long test surface required to fill the Steiner Tunnel furnace.

        Coatings

    The coating material was applied to the test surfaces by a representative of the submitter under the observation of a staff member of Underwriters Laboratories Inc.  The coating material was brush applied in one coat.  The amount of coating applied was determined by weight.

    One fire retardant coating was evaluated under this investigation and was identified by the manufacturer as "FX-100".  The coating was applied at a rate of 210 sq. ft. per gallon.

    The test samples were conditioned for 28 days at a temperature of 70 ± 5° and relative humidity of 45 to 55 percent before testing.

.
METHOD
    The tests were conducted in accordance with Underwriters Laboratories Inc.'s Standard  "Test for Surface Burning Characteristics of Building Materials", UL 723.
.
RESULTS
    Data on flame spread and smoke developed, results appear in  the following tabulations and as shown on Ills.  1 through  8:

Flame Spread:
 

    The maximum distance the flame spreads along the length of the sample from the end of the igniting flame is determined by observation.

    The Flame Spread Classification of the material is derived by determining the area under the flame spreads distance (ft.) versus time (min.) curve, ignoring any flame front recession, and using one of the calculation methods as described below:

        1.  If the total area (At) is less than or equal to 97.5 min. -ft  (meter-min.  x  3.3),  The Flame Spread Classification shall be 0.515 times the total area  (FSC = 0.515  At).

        2.  If the total area (At) is greater than 97.5 min -ft (meter-min.  x  3.3)  The Flame Spread Classification is to be 4900 divided by 195 minus the total area (At).  (FSC = 4900/(195-At)).

Smoke Developed

    The smoke developed during the test is indicated by the output of a photoelectric circuit operating across the furnace flue pipe.  A curve is developed by plotting values of light absorption  (decreased cell output)  against time. The calculated value for Smoke Developed Classification is derived by expressing the net area under the curve for this material as a percentage of the net area under the curve for untreated red oak.

Subject : Omega Point Laboratories Test Report
          "FX-100® FIRE PROTECTIVE COATING" on plywood panels
 

The March 24, 1994 test was performed to show the fire performance of FX-100® COATING when applied to standard decking material (1/2" CDX PINE PLYWOOD) with a worst case scenario included which involved the primary flame impingement being a "joint" in the system. You will notice that there were six panels used, each 24 inches in length. This placed a joint at the point of contact of the test flame in the furnace.

Note that the test did prove similar performance as the U.L. E-84 performed on Douglas Fir where the flame impingement was not at a joint. The intumescent expansion performed well in that it covered over the small gap at the joints.  The flame spread was almost identical to the U.L. test with the only difference being that slightly more smoke was evolved from the test sample when the joint was first exposed to the flame as the heat affected the ends of the test pieces until sufficient intumescent expansion insulated the material.

I.  INTRODUCTION

This report describes the results of the ASTM E84-91a Standard Test Method for SURFACE BURNING CHARACTERISTICS OF BUILDING MATERIALS (1),  a method for determining the comparative surface burning behavior of building materials. The test is applicable to exposed surfaces, such as ceilings or walls, provided that the material or assembly of materials, by its own structural quality or the manner in which it is tested and intended for use, is capable of supporting itself in position or being supported during the test period.

The purpose of the method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke density developed are reported, however, there is not necessarily a relationship between these two measurements.

"The use of supporting materials on the underside of the test specimen may lower the flame spread index from that which might be obtained if the specimen could be tested without such support... This method may not be appropriate for obtaining comparative surface burning behavior of some cellular plastic materials... Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place."

This test method is also published under the following designations:

ANSI 2.5
NFPA 255
UBC 42-1
UL 723
This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

II. PURPOSE
 

The ASTM E84-91a  (25 foot tunnel) test method is intended to compare the surface flame spread and smoke developed measurements to those obtained from tests of mineral fiber cement board and select grade red oak flooring. The test specimen surface (18 inches wide and 24 feet long) is exposed to a flaming fire exposure during the 10 minute test duration, while flame spread over its surface and density of the resulting smoke are measured and recorded. Test results are presented as the computed comparisons to the standard calibration materials.
The furnace is considered under calibration when a 10 minute test of red oak decking will pass flame out the end of the tunnel in five minutes, 30 seconds, plus or minus 15 seconds. Mineral fiber cement board forms the zero point, while the red oak flooring flame spread and smoke developed ratings are set as 100.

V. OBSERVATIONS

The coating became intumescent at 0:08 (min:sec). Sample ignition was observed through the tunnel windows, and occurred at approximately 0:30 (min:sec). Char formed a thickness of 1" at 1:00(min:sec), 1.5" at 1:15(min:sec), 2" at 2:05(min:sec), 3" at 3:25(min:sec), and 4" at 4:15(min:sec).  Maximum flame spread of 2.0' occurred at 9:46(min:sec).

After cooling and removal from the tunnel, the specimen was observed as follows: The coating was intumescent to 24', and was approximately 3" thick. Channels had formed in the intumescent coating at 2', 4', 6', 8', 10', 12', 16' and 20', thus exposing the substrate (plywood) and allowing char to form on the plywood.  Partial consumption of the plywood was noticed between 4'and 5'.
