What is a Through Penetration in construction?

A Through Penetration in construction refers to an opening that goes completely through an assembly. This type of penetration is common in various construction contexts, particularly in fire-rated walls and floors where services such as electrical conduits, plumbing, and mechanical ducts may need to pass through.

The term emphasizes the nature of the opening, highlighting that it penetrates from one side of the assembly to the opposite side, thereby affecting not only the assembly itself but also requiring consideration for fire safety and sound transmission. Proper treatment around these penetrations is essential to maintain the integrity of the assembly and comply with building codes.

Other options describe different aspects of construction but do not accurately define Through Penetration. For instance, a method of connecting two walls does not directly address the concept of an opening, while an opening that pierces one side of an assembly only describes a partial penetration. Similarly, a structural support element pertains to the framework of construction, which is unrelated to the definition of a penetration in this context.
