Engineered Wood I-Beams Exposed to Fire Part two, new construction, nearly half of all new residential construction utilize engineered wood I-beams, these and other truss floor components are the norm for wood construction. Residential buildings built after 1990 are suspect for haven engineered wood I-beams or some type of truss floor system. The hazards and risks of engineered wood I-beams is they burn rapidly due to a very high surface to mass ratio characteristic of kindling. Just like a common truss, the engineered wood I-beam substitute geometry for mass to support the intended load. Engineered wood I-Beams rely on their depth for stability and allow for a reduction of material to carry the intended load. A reduction in mass means a much faster burn time and alot less time to struc...
