If you’re preparing for the installation of your new siding, you might already have encountered the option of adding a house wrap. This topic can be a little confusing, especially since the purpose of house wraps can vary.
In this post, Century Roofing and Siding, shares some basic information on house wraps. We also offer tips on how you can determine if you should opt for one before siding replacement.
What Is a House Wrap?
A house wrap can serve as a barrier against moisture or wind, depending on how it is installed. When used against winds, house wraps typically function in a way that seals gaps and leaks in the OSB panels or plywood sheathing. This keeps drafts from reaching your insulation, and it prevents heated and cooled air from permeating your walls.
House wraps do pretty much the same thing when they serve as a moisture barrier. Since they’re typically made from a permeable material, they allow water vapor to travel through them while keeping water droplets out. Because of this design, house wraps are able to dry out quickly, preventing the growth of mold.
Should I Get a House Wrap Before Siding Installation?
Requirements pertaining to house wraps are usually addressed in local building codes, so that should be one of the first things you should check before planning for your siding installation project. Apart from that, you should consult a professional builder or your contractor regarding the type of house wrap that your home needs.
Typically, homes with wood, vinyl or aluminum siding benefit the most from house wraps. Wood cladding usually has many seams where boards overlap. Meanwhile, for vinyl or aluminum siding, water can possibly enter through the cracks where the panels are joined. In terms of climate, vapor barriers are generally recommended for homes in colder regions.
