Introduction

When it comes to building materials, Typar and Tyvek are two popular choices for house wrap. Both products are designed to protect buildings from moisture and air infiltration, but they have some key differences in terms of their attributes and performance. In this article, we will compare Typar and Tyvek in terms of their durability, water resistance, breathability, and installation process.

Durability

Typar is known for its durability and strength. It is made from a high-density polyethylene material that is tear-resistant and can withstand harsh weather conditions. Tyvek, on the other hand, is made from spunbonded olefin, which is also durable but may not be as strong as Typar. Both products are designed to last for many years, but Typar may have a slight edge in terms of long-term durability.

Water Resistance

When it comes to water resistance, both Typar and Tyvek are excellent choices. Typar has a unique non-woven structure that allows water vapor to escape while preventing liquid water from entering the building envelope. Tyvek also has good water resistance properties, thanks to its unique microfiber structure. In terms of water resistance, both products are on par with each other.

Breathability

One of the key differences between Typar and Tyvek is their breathability. Typar is known for its high breathability, allowing moisture vapor to escape from the building envelope. This can help prevent mold and mildew growth inside the walls. Tyvek, on the other hand, has slightly lower breathability compared to Typar. While both products are breathable, Typar may have a slight edge in this category.

Installation Process

Both Typar and Tyvek are relatively easy to install, but they have some differences in terms of their installation process. Typar comes in rolls that are easy to handle and cut to size. It can be installed using staples or nails, making it a versatile option for builders. Tyvek, on the other hand, comes in sheets that need to be carefully taped and sealed to ensure proper installation. While both products can be installed by professionals, Typar may be slightly easier to work with for DIY enthusiasts.

Conclusion

In conclusion, Typar and Tyvek are both excellent choices for house wrap materials. Typar is known for its durability, high breathability, and ease of installation, while Tyvek offers good water resistance and durability. Ultimately, the choice between Typar and Tyvek will depend on the specific needs of the project and the preferences of the builder. Both products have their own strengths and weaknesses, so it is important to carefully consider the attributes of each before making a decision.
