Type 5 construction is primarily characterized by which material?

Type 5 construction is primarily characterized by the use of wood as its main structural material. This type of construction involves the use of light-frame wood, which can include timber, plywood, and oriented strand board (OSB). One of the defining features of Type 5 construction is its reliance on combustible materials, making it significantly different from other construction types that utilize non-combustible materials.

Due to the use of wood, buildings categorized under Type 5 are generally lighter and more flexible. They often have lighter roofs, walls, and floors in contrast to types that utilize heavier materials such as concrete or masonry. This type of construction is commonly used in residential buildings and smaller commercial properties because it is cost-effective and allows for quicker building times.

Additionally, wood-framed structures can be susceptible to fire, leading to faster fire spread, which is a foundational aspect of fire safety training and risk management for firefighters. Understanding the materials and structure of a building can greatly aid firefighters in assessing potential hazards and planning effective fire suppression strategies.
