Questions and Answers

Which of the following best describes a knee wall in timber roof construction?

  • A wall that surrounds the void space in the attic
  • A wall that separates the attic from the living space
  • A wall that creates more occupiable space within the attic
  • A load-bearing wall that supports the rafters (correct)

    • What is the impact of knee wall construction on fire dynamics?

  • It allows for rapid fire growth in the attic
  • It limits natural ventilation and keeps the fire small (correct)
  • It creates a detectable rise in temperature in the attic
  • It prevents fire spread in the attic

    • Why do open windows in the attic increase the temperature rapidly during a fire?

  • They prevent fire spread to other areas of the building
  • They provide an additional exit route for potential victims
  • They allow more air to reach the fire (correct)
  • They allow for better visibility for interior crews

    • Which type of fires are more complicated to access and extinguish?
