Time to select a house wrap system

Protecting the walls and roof of my new home from wind, moisture and infiltration is super important, especially during the stages of construction when the frame of my home will be more vulnerable to the elements.

Now that the framing of my eco-friendly home is mostly complete, it’s time to protect the structure that I’ve invested so much time and energy on so far. Generally, home builders do this by wrapping the unfinished structure in a protective layer of man-made film that allows moisture to escape while not allowing any to pass through the barrier from the outside. House wrap helps keep the structure dry and keeps the materials in good condition until the outer layers of the home can be applied.



By preventing water from penetrating the structure, mold is not able to form and rot is not able to take hold on the structure. This is important when you’ve spent thousands of dollars on building materials and hundreds of man hours building a structure that you plan to live in.

When most people think of house wrap, the word “Tyvek” comes to mind. DuPont’s Tyvek is made of a continuous, non-woven, non perforated sheet. DuPont claims that there are no performance tradeoffs with Tyvek compared to perforated wraps. However, I know from experience that it’s important to examine all of my options and make my choice based on a number of factors including construction techniques, climate, and the environment in which I am building.



So for this portion of my project, I’m having house wrap expert Andrew Vissar of GCP Applied Technologies take a look at my project and make some recommendations to me. One product that Andrew is pretty excited about is relatively new to the residential construction market. It’s called VyCor enVs - VyCor is a fully adhered material that works especially well in the climate of the northeast.



I’m looking for a product that will bond to the walls of my home and seal around the fasteners with no problem - one thing I like about VyCor is that I won’t have to use any extra tapes in order to apply it. I’m hoping that Andrew’s demonstration of how this material works will provide you and I with some extra education about the advancements in proprietary house wrap materials.

What has your experience been with house wrap? Do you have a favorite material that you like to use? Join the conversation and let us know!
