- In House Wrap
The performance of a high-quality, vapor-permeable, house wrap is dependent on proper installation, careful handling, and limited exposure to UV radiation and outside elements. The goal of house wrap is to create an air and moisture barrier that also prevents moisture accumulation in the wall system. Ultimately, house wrap should boost a home’s energy-efficiency and create a healthy, comfortable indoor environment. Common problems with house wrap can occur if not installed correctly. Further problems will occur if roughly handled or overly exposed to UV radiation and outside elements. All of these problems can diminish a house wrap’s resistance to air and moisture, along with its permeability.
Improper House Wrap Installation
House wrap is often a synthetic and lightweight material that goes over a home’s sheathing and behind the siding. Correct installation of house wrap, according to manufacturer instructions, is critical to its performance. Incorrect installation of house wrap can affect a home’s ventilation and lead to a buildup of moisture in the wall cavities. Experienced and skilled house wrap installers avoid common problems with house wrap by following several key steps when installing house wrap.
Seal all seams with manufacturer recommended tape, including over the layers, the top and bottom edges, and the rough openings. It is also essential to seal the areas cut by subcontractors during the installation of the cladding.
House wrap is typically applied from the bottom of the building up, overlapping the horizontal joints by a minimum of six inches and the vertical joints by a minimum of twelve inches. Expand the house wrap over the footing top by a minimum of two inches. The house wrap should be fixed every 12 to 18 inches with specific stapling nails or nails designed to hold down house wrap material.
Installation of house wrap around the window and door openings involves a Y-cut from corner to corner in the openings. Then, the loose material is folded through the openings and fastened securely.
Problems with House Wrap Due to Rough Handling
Rough handling or long exposures to wind and construction debris can tear, rip, and cut the house wrap. These damaged areas of the house wrap will allow air and moisture to enter the wall system. It is critical to seal and repair all damage to the house wrap due to rough handling and overexposure to wind and construction debris.
House Wrap Damage Due to Overexposure to UV Radiation

Overexposure of house wrap to the sun’s ultraviolet (UV) rays can discolor and photodegrade the house wrap. UV exposure can also cause the house wrap to loss tensile strength and water repellency. In some cases, this can happen quickly, depending on the house wrap’s ultraviolet (UV) rating. The UV-rating of a house wrap is the maximum time a house wrap can withstand exposure from the sun before becoming damaged.
