How is house wrap installation similar to Grade D paper and #15 felt installation?

House wrap installation shares similarities with Grade D paper and #15 felt installation in that horizontal seams must be lapped in a shingle fashion, and vertical seams should also be lapped. This method mimics the way roofing materials are typically overlapped to prevent water infiltration, ensuring that any water that encounters the seams will flow down the surface rather than seeping through.

Lapping the seams horizontally in a shingle fashion allows for an effective barrier against moisture and provides additional protection to the building structure. Vertical seams that are also lapped contribute to the integrity of the moisture barrier, helping to create a continuous shield against external elements. This overlapping technique is crucial for maintaining the effectiveness of the weather-resistive barriers in both wall and roofing applications.

The other choices do not capture this important aspect of installation. For instance, while tape may be used in some scenarios, it's not a blanket requirement for vertical seams across all materials. The same adhesive necessity mentioned doesn't apply since different materials can use various types of adhesive. Finally, stating that only horizontal seams are important disregards the necessity of properly addressing vertical seams to ensure comprehensive protection against moisture.
