Fire performance of fire‐retardant wood fiberboard ceiling tile

Abstract

Wood fiberboard-based, cellulose ceiling tiles have been used for many years. While various fire-retardant technologies have been developed to reduce the surface flammability of these products to acceptable levels, questions of their suitability for use due to their intrinsic fuel value and the impact of attachment methods used on fire performance have been raised from time to time. This paper reviews the history of these products from a fire-performance perspective and presents materials property data on surface flamespread, thermal conductivity and ignition phenomena. In addition, large-scale room fire test results are presented including compartment tests conducted on a variety of assemblies (including those installed with mastic construction adhesives) according to ASTM E 603-Standard Guide for Room Fire Experiments.

Influence of Physical–Mechanical Strength and Water Absorption Capacity on Sawdust–Waste Paper–Recycled Plastic Hybrid Composite for Ceiling Tile Application

“…Thermal conductivity L, defined by the steady-state heat flow moving through a unit area of a homogeneous material, 1 m thick, induced by a 1 K difference temperature on its faces, is one of the most interesting characteristics of thermal insulation materials [22]. The temperature analysis of the composite ceiling boards was carried out according to ASTM C-518 standards [30,31]. This involved the use of accurate digital thermocouples kept at 25 • C. An external heat sensor was placed on the board.…”

Fire Retardant Coatings

“…When heated, wood undergoes degradation and combustion to produce volatile gases, tars (levoglucosan), and carbonaceous chars. The fire performance of wood-based products and test methods has been reviewed and studied extensively [12][13][14][15][16][17][18][19][20][21][22]. Traditional flame retardants, such as boron compounds, mineral acids, and inorganic salts, (monoammonium phosphate, diammonium phosphate, guanylurea phosphate, guanidine phosphate, ammonium polyphosphate, and melamine phosphate), may considerably improve the fire retardant properties of wood [23].…”
