Ember Characteristics

Research IBHS studies the characteristics of embers from different fuel sources, including vegetative and structural, and implications regarding their ability to ignite buildings and other combustible materials on the property. This work will ultimately help improve guidance for homeowners and communities. This research is a collaborative effort with researchers at UNC Charlotte, University of Maryland, University…

Flame Spread: Pine Straw

Research Researchers from the USDA Forest Service Fire Sciences Laboratory in Missoula, Montana, are working with IBHS scientists to investigate the influence of wind speed on flame spread in pine needle beds. The relation between wildland fire rate of spread and wind speed used in the US wildland fire behavior decision support systems was developed…

Fire‐Retardant Gels

Research In a study conducted in collaboration with the University of North Carolina at Charlotte, IBHS evaluated the long‐term effectiveness of two fire‐retardant gels when applied to a wood‐based substrate. Gels are a type of coating meant to provide protection for a short period, a few hours, and are typically applied manually just prior to…

Wind Loads on Components of Multi-Layer Wall Systems with Air-Permeable Exterior Cladding

Research Post-hurricane damage assessments have documented the failure of wall components and connections including the loss of various types of siding materials. In addition, recent US model building/energy code changes are expected to lead to increased use of continuous insulation, particularly foam sheathing attached to the exterior surface of light-frame wall framing, to achieve advanced…
