Question

________ in a building envelope assembly orcomponent is a penetration of the insulation layer by a

highly conductive or noninsulating material (e.g., concrete or steel).

Answer 1

In engineering, a penetration refers to the intrusion of a highly conductive or non-insulating material through the insulation layer of a building envelope assembly or component. It occurs when there are gaps or openings in the insulation system, allowing heat to transfer more readily.

Step-by-step explanation:

Penetration in a building envelope assembly or component refers to the intrusion of a highly conductive or non-insulating material, such as concrete or steel, through the insulation layer.

This can occur when there are gaps or openings in the insulation system, allowing heat to transfer more readily through the building envelope. For example, a steel column passing through an insulated wall would be considered a penetration.
