Question

proper installation of which of the following controls air infiltration for maximum energy efficiency in a structure?
building wrap
waterproofing
rigid insulation
plastic sheathing

Explanation:

Building wrap is a material that is installed on the exterior of a building's walls. Its main function is to control air infiltration. By creating a barrier, it helps to prevent air from entering or exiting the building envelope, which is crucial for maximum energy efficiency. Waterproofing is mainly about preventing water penetration. Rigid insulation is for thermal resistance. Plastic sheathing is more about a basic covering and not specifically designed for optimal air infiltration control like building wrap.

Answer:

building wrap
