Some building codes require wood shingles to be fire-retardant treated. Because exterior fire-retardant treatments are subjected to weathering, treatment durability and leach resistance are critical for insuring adequate fire protection. We examined the effectiveness of various fire-retardant treatments on wood after 0, 2, 5, and 10 years.

The FSR Treatment, Inc., fire-retardant-treated wood shakes and shingles described in this report comply with, or are suitable alternatives to what is specified in, those codes listed in Section of this report, subject to the following conditions: See Sectionexcept change the word “nonclassified” to.

The high replacement costs of wood roofs and the development of new preservative finishes that are cheaper, less toxic, and more durable has made treating wood roofs, feasible and desirable.

Introduction Shingle Seal™ is an application ready, water-based fire retardant designed for treatment of wood roofing and/or siding shingles.

Shingle Seal™ is mix of proprietary ingredients, which forms a slight intumescent foam layer and carbon char when the treated shingle or shake is exposed to fire. Once the carbon char is formed there will be minimal flame propagation, smoke evolution.

FirePRO FRTW is typically specified for use where the building code jurisdiction permits the use of wood or fire retardant treated wood.

Does the fire retardant treatment affect the color of my cedar shakes and shingles. The color will be slightly darker brown, but they will weather to an appealing gray over time. Does fire retardant treatment reduce the longevity of cedar shakes or shingles.

Select the Certi-Guard™ permanent label if fire-retardant is needed where the threat of fire exists.

Description Evaluation of fire-retardant treatments for wood shingles PDF

This treatment results in a Class A rating for fire resistance (figure 3). Figure 3—Fire-retardant treated wood shingles. There are three different classes of fire retardant treatments available.

Check with your local building official to determine which Class A, B or C roof is best suited in your area. FSR’s fire retardant treatment is offered for all specifications of Western Red Cedar Shakes and Shingles.

FTX® Treated Fire Retardant Cedar Shakes and Shingles For fire hazardous areas, such as California, cedar shakes and shingles with FTX fire retardant treatment provide permanent fire protection.

FTX was the first legal fire retardant treatment approved by the California State Fire Marshal, including Class A, B, and C application.

The fire-retardant-treated wood shake and shingle roof coverings are for use where Class A, B or C wood roof coverings are permitted. DESCRIPTION The fire-retardant-treated wood shakes and shingles are produced from No.

Fire-retardant-treated products for exterior applications must be subjected to actual or accelerated weathering prior to fire testing.

For fire-retardant-treated wood, the two accelerated weathering methods have been Method A and B of ASTM D The rain test is Method A of ASTM D Use of Preservative-treated Wood Requires Certain Precautions Monica Keels: By: Mark Rupar, NRCA Director of Technical Services.

Selecting appropriate fasteners when using preservative-treated wood is complicated by the variety of available preservative treatments that can be corrosive to metal preservative systems are used by preservative-treated wood manufacturers in the.

The Pressure Treatment Process. Our Pressure Impregnation Fire Retardation Treatment System begins as the cedar shakes and shingles are loaded into our pressure autoclave cylinder.

All air and moisture is removed from the wood by a vacuum, at which point the fire retardant is pumped into the cylinder to thoroughly saturate the wood. Our fire-retardant wood protection products are designed to prevent the spread of flames and the development of smoke as well as protecting against pests and fungus.

FS2 is a water-based, post-treatment, interior/exterior fire retardant, and wood preservative that penetrates the material and bonds with the cellular structure.

FS2 contains polymers that maintain the fire retardation for up to five years for exterior applications. Today, there are cedar roof shingles and shakes available that have been pressure-treated with fire-resistant chemicals at the factory and can achieve a class B or C fire resistance rating.

Fire retardant coatings are often required to protect a wide range of products of both flammable and nonflammable against fire. It is an oldest, most efficient, and easiest method to apply any surface without modifying the intrinsic properties of materials. Moreover, the initial phase of fire always occurs on the surface by ignition, and hence, it is important to concentrate on the surface.

Source Quality: Obtain fire retardant treated wood from a single licensed manufacturer. Wood Treatment Plant Qualifications: Wood treatment plant experienced in performing work of this section which has specialized in the treatment of wood similar to that required for this project, licensed by the manufacturer, with ongoing third.

Fire-Retardant Wood Shakes/Shingles; These roofing shingles are pressure treated with fire retardant that is injected into the wood and is locked into its fibers. This ensures that the material remains fire retardant for its lifetime.

A “Class A” fire rating is attainable for the roof system. Spray-applied or brushed-on, fire retardant coatings (FRCs) provide treated materials with best in class passive fire protection. No-Burn ®, Inc.’s fire retardant coatings have all received “Class A” or “Class 1” designations, in accordance with international building codes and the National Fire Protection Association’s standards, over a variety of substrates.These requirements cite the code-required testing and guidance for design value adjustments for fire retardant-treated wood products.

UL FR-S. Underwriters Laboratories provide an FR-S rating for fire retardant lumber and plywood, which indicates the wood has a flame spread and smoke developed rating of 25 or less as determined by the ASTM E FRT Wood Is Fire-retardant-treated wood.

Fire-retardant-treated wood is any wood product which, when impregnated with chemicals by a pressure process or other means during manufacture, shall have, when tested in accordance with ASTM E 84 or ULa listed flame spread index of 25 or less and show no evidence.
