What is a Housewrap in Construction? A Comprehensive Overview

In the realm of construction, housewrap plays a vital role in ensuring the durability and energy efficiency of buildings. This brief review aims to provide a simple and easy-to-understand explanation of what a housewrap is, along with its benefits and the ideal conditions for its use.

I. Understanding Housewrap:

Housewrap is a material used in construction to act as a protective barrier between the exterior cladding and the underlying structure of a building. It is typically made from synthetic materials such as polyethylene, polypropylene, or a combination of both.
