What is it:

Tyvek HomeWrap is an air and water-resistive barrier (WRB), shielding homes from wind and rain that may seep through exterior cladding. Its breathable structure allows moisture vapor to pass through, while allowing drying within wall systems. 

This synthetic nonwoven material offers protection even during the construction phase. While your home is under construction, Tyvek serves as a dependable barrier against the elements, safeguarding it from adverse weather conditions that may arise before the exterior cladding is installed.

Installation:

Tyveck can be installed with staples or cap nails/fasteners. Minimal taping is required, typically only at the ends and where the sheets overlap. This versatility makes for an efficient installation process alongside conventional wall sheathing materials.

Durability:

Choosing a good house wrap is vital to protect a building from the elements. It must withstand tears and punctures caused by wind and accidental impacts on the job site. Prolonged exposure to UV rays can also compromise the integrity of the WRB. 

Tyvek Vs. Perforated House Wraps:

When comparing Tyvek with perforated wraps, significant differences become apparent. While perforated wraps may seem cost-effective initially, they are typically constructed from woven polypropylene slit film, which lacks effectiveness in blocking air and water. Manufacturers attempt to address this weakness by adding a polypropylene film coating, resulting in a non-breathable vapor barrier. Despite adding micro-perforations to allow moisture out, these openings also allow for the penetration of air and water. 

Summary: 

In summary, Tyvek stands out as a cost-effective and widely-used method for providing a home’s weather-resistant barrier. It serves as a robust solution for weatherizing homes, effectively managing moisture, and offering durability and ease of installation. This ensures the long-term integrity and performance of buildings.
