    Use of structural composite lumber products is increasing. In applications requiring a fire resistance rating, calculation procedures are used to obtain the fire resistance rating of exposed structural wood products. A critical factor in the calculation procedures is char rate for ASTM E 119 fire exposure. In this study, we tested 14 structural composite lumber products to determine char rate when subjected to the fire exposure of the standard fire resistance test. Char rate tests on 10 of the composite lumber products were also conducted in an intermediate-scale horizontal furnace. The National Design Specification/Technical Report 10 design procedure for calculating fire resistance ratings of exposed wood members can be used to predict failure times for members loaded in tension. Thirteen tests were conducted in which composite lumber products were loaded in tension as they were subjected to the standard fire exposure of ASTM E 119. Charring rates, observed failure times in tension tests, and deviations from predicted failure times of the structural composite lumber products were within expected range of results for sawn lumber and glued laminated timbers.

      Floors must have a subfloor of at least 15/32″ wood structural panels or 11/16″ T&G. Roofs must have a deck of at least 15/32″ wood structural panels or 11/16″ T&G and finished roofing. There are quite a few additional rules for fire resistance so please ask questions. density, and moisture content. Options for improving the fire resistance with coatings have also been investigated (White ). Results for the charring rates of composite lumber products were reported at the Wood and Fire Safety Confer-ence (White ). In these tests, thermocouples were placed at different depths to get the charring rates.

    Structural Composite Lumber (SCL) Structural composite lumber (SCL) is a term used to encompass the family of engineered wood products that includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL).. With its ability to be manufactured using small, fast-grow and underutilized trees, SCL products represent an . 8 FIRE PROTECTION The fire resistance requirement for a building and therefore the frame is defined in terms of the fire resistance period and stated in terms of minutes (15, 30, 45, 60, 75, 90 or minutes). The purpose of setting a fire resistance period is to ensure that in the event of a fire.

Leesburg, VA. Structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture resistant adhesive into blocks of material known.

OZ Architects used structural composite lumber (SCL) for the Rocky Mountain Elk Foundation building in Missoula, Montana. Compression members Design load ratios, R s, for fire design of columns are calculated as the product of two ratios, R s1 and R of R s1 and R s2 for various column sizes are tabulated in DCA 2 for one-hour, hour, and two-hour fire resistance ratings.

Even though noncombustible decking products are available (e.g., metal decking and lightweight concrete), many decking products are combustible. Untreated wood and wood treated with fire retardant, as well as plastic and wood-plastic composite products, are all combustible and therefore vulnerable to ember and other wildfire exposures.

The performance of structural composite lumber is affected by wood species, wood element size and shape, and adhesive and production parameters. Therefore, products produced by each individual manufacturer shall be evaluated to determine their product properties, regardless of the similarity in characteristics to products produced by other manufacturers.

3) Fire classification of structures. Construction materials and products are classified according to how they react to fire, but structures such as roofs and walls – as well as systems such as ventilation ducts and pipes – are classified based on their fire following properties are.

A load-bearing fire resistance test was carried out on a larger LVL beam spanning 4 m in a full size furnace, following the ISO˜ standard fire curve. Keywords: Charring, fire performance, ignition, laminated veneer lumber, LVL 1.

Introduction Fire is one of the most unpredictable and dangerous accidents that may occur in our environment. TimberTech decking brings you high-style, low-maintenance composite decking products— all backed by industry-leading warranties.

Use the filters to find the boards with the right color, pricing, and features for. In order for wood to be used to make composite products, feedstock originating from trees and logs must first be obtained, sometimes as a by-product of other primary wood processing operations.

This chapter provides a summary of primary wood processing as it relates to the production of the raw materials used in wood composites. Fire resistance data on exposed wood beams and columns are plentiful, but few studies have been done on exposed wood members in tension and in decks.

To provide data to verify the application of a new calculation procedure, a limited series of fire resistance tests were conducted on wood members loaded in tension and on exposed wood decks.

Use of structural composite lumber products is increasing. In applications requiring a fire resistance rating, calculation procedures are used to obtain the fire resistance rating of exposed structural wood products.

A critical factor in the calculation procedures is char rate for ASTM E fire exposure. In this study, we tested 14 structural composite lumber products to. Mass timber includes any product currently permitted for use in Type IV construction, such as Cross Laminated Timber (CLT), Structural Composite Lumber, glued-laminated timber, and large section sawn lumber.

Because of the unique structural and fire resistance characteristics of solid timber walls and floors (CLT) and mass timber structures. Fire Design of Exposed Wood Members. The fire resistance of exposed wood members, including lumber, glued laminated timber, and structural composite lumber (SCL), may be calculated using provisions of Chapter 16 of AWC’s National Design Specification ® (NDS ®) for Wood allowable stress design approach is referenced in International Building Code (IBC) Section Structural composite lumber (SCL) – SCL is a family of wood products created by layering dried and graded wood veneers, strands, or flakes with moisture-resistant adhesive into blocks of material, which are subsequently re-sawn into specified sizes.

Two SCL products—laminated. Fire Resistance Fire resistance is typically presented as a duration of time. The fire resistance of an element (wall, floor or roof) is a measure of its ability to withstand the effects of fire in one or more ways as follows (see Figure 2 also): • Structural ‘loadbearing capacity’ to maintain the design loads under fire.

Issue Required Fire Resistance Ratings for Structural Building Elements. By Arthur J. Parker, P.E., and Jesse J. Beitel. The building codes prescriptively require minimum fire-resistance ratings for structural building elements such as the structural frame, floor construction, walls (interior and exterior) and roof construction.

Fire resistance tests were completed on a wide range of laminated veneer lumber products and other composite products for structural applications. Data will facilitate the application of code-approved methodologies for the design of fire-rated exposed wood members to composite wood products.Early efforts to make fiberboard fire RESISTANT show up in patent disclosures and fiberboard sheathing product modern fire ratings are discussed by the various manufacturers of fiberbboard such as Georgia Pacific and Homasote.
