Which of the following is NOT an advantage of a truss system?

A truss system is well-known for several advantages that enhance its functionality and effectiveness in various construction applications. The choice identifying increased attic storage space as not being an advantage of a truss system is accurate for several reasons.

Truss systems are primarily designed to provide strength and support while minimizing the amount of material used. By distributing loads efficiently across the structure, trusses allow for larger spans and more open areas beneath, which can be beneficial for overall building design. However, the geometric shape of trusses often means that they create sloped ceilings or irregular shapes that can limit usable space in the attic. This can lead to less practical storage options compared to framed roof systems, which can allow for more straightforward, easily accessible attic areas.

In contrast, the other choices reflect recognized benefits of truss systems. Their efficiency in material use makes them a cost-effective solution, while their capability to span large distances is a key characteristic that allows for expansive open spaces in buildings. Additionally, the design of trusses is often more conducive to faster installation due to prefabrication, which can save time on the construction site. Understanding these distinctions highlights why increased attic storage space is not typically considered an advantage of truss systems.
