D. Composite Decking: Deck boards manufactured from wood fiber and plastic. ASTM. D7032, Section 3.2.8 defines wood-plastic composite (WPC) as a composite made primarily from wood- or cellulose-based materials and plastic(s). E. FSI: Flame Spread Index. F. HDPE: High density polyethylene. G. LDPE: Low density 

INEX DECKING™. INEX>DECKING is a unique Engineered Cementitious Composite (ECC) material; an advanced low carbon concrete developed by UBIQ and containing up . Heat Evolved Index. 0. AS/NZS 1530.3:1999. Smoke Developed Index. 1. AS/NZS 1530.3:1999. Combustibility. PASS - Not deemed Combustible.

Fire-retardant treatments are necessary when a Class A flame spread index is required for a wood product. Some domestic softwood species meet the Class B flame spread index without treatment. Other domestic softwood species have FSIs near the upper limit of. 200 for Class C. All available data for domestic hardwoods.

Smoke-developed index (abbreviated SDI) is a measure of the concentration of smoke a material emits as it burns. Like Flame Spread Index, it is based on an arbitrary scale in which asbestos-cement board has a value of 0, and red oak wood has 100. The SDI is measured using a horizontal test specimen, according to the

Similarly, if no ceiling is installed beneath a floor or roof assembly, the unfinished exposed deck and structural members are considered to be the interior ceiling finish. This is why the NBCC assigns the same flame-spread and smoke developed rating to common materials such as plywood, lumber and gypsum wallboard

Many common construction materials are combustible, including wood and wood-plastic composite and plastic products (commonly used for decking and With regard to wildfire, two properties are helpful in characterizing the relative combustibility of different materials – flame spread index and heat 

These provisions shall govern the materials, design, application, construction and installation of foam plastic, foam plastic insulation, plastic veneer, interior plastic WOOD/PLASTIC COMPOSITE. Loose fill-type foam plastic insulation shall be tested as board stock for the flame spread and smoke-developed indexes.

Piping materials such as cast iron, which are classified as non-combustible per ASTM E 136, can be installed within un-ducted return air plenum spaces without restriction. Understanding Flame Spread Index (FSI) and. Smoke Developed Index (SDI) Ratings. Technical Bulletin #161028. Considering installing a plastic 

Since the regulations have been around for a while now, more materials have improved to meet this standard. But some composite decking materials probably have not or may never be tested for this kind of application. Most composite decking manufacturers have fire testing data and its called a flame spread index from 

Exterior walls … shall be constructed with materials approved for a minimum of 1-hour fire-resistance-rated construction on the exterior side or . Local building departments are likely to want to know the Flame Spread and Smoke Developed Index of a particular composite decking before allowing its use in
