There are many different types of tape that can be used as a vapor barrier. The most common type of tape is made of aluminum, but there are also tapes made of other materials such as polyethylene and polypropylene. Aluminum tape is typically used for ductwork and is available in various widths and thicknesses.

Polyethylene and polypropylene tapes are often used for sealing seams on vapor barriers, but they can also be used for general purpose sealing.

If you’re looking for a vapor barrier to use in your home, there are a few things to consider. One is the type of tape you’ll need to seal it properly. Here’s a quick guide to help you choose the right tape for your vapor barrier.

Different Types of Tape There are three main types of tape that can be used for a vapor barrier: duct tape, foil tape, and cloth-backed adhesive tapes. Duct tape is the most common type of tape used for this purpose, but it’s not always the best option.

It can be difficult to apply and remove, and it doesn’t always adhere well to different surfaces. Foil tape is a better option in many cases, as it’s easier to apply and remove and has a stronger adhesive. Cloth-backed adhesive tapes are also an option, but they’re not as widely available as the other two types of tape.

Which Type of Tape Should You Use? The type of vapor barrier you’re using will dictate which type of tape is best suited for the job. For example, if you’re using an airtight vapour barrier like polyethylene film or polyurethane film, duct tape is a good choice.

If you’re using a less airtight vapour barrier like kraft paper or fibreglass insulation, foil tape or cloth-backed adhesive tapes are better options. Whichever type of vapor barrier you choose, make sure the edges are properly sealed with Tape so that no air can get through.

Best Tape for Crawl Space Vapor Barrier

There are a few things to consider when selecting the best tape for your crawl space vapor barrier. The first is the width of the tape. You’ll want to choose a tape that is at least 4 inches wide.

This will ensure that it will be able to seal the seams of your vapor barrier correctly. The second thing to consider is the type of adhesive on the back of the tape. You’ll want to choose a tape with an acrylic adhesive.

This type of adhesive will hold up well in high humidity environments, like crawl spaces. Finally, you’ll want to make sure that the tape you select can withstand temperatures as low as -20 degrees Fahrenheit. This will ensure that it won’t lose its stickiness in cold weather conditions.

How Do You Tape down Vapor Barrier?

There are a few ways to tape down vapor barrier, and the best method may depend on the type of surface you’re working with. For example, if you’re taping vapor barrier to drywall, you might use a different method than if you’re taping it to concrete. Here are a few options for taping down vapor barrier:

– Use painters’ tape. This is one of the easiest methods, and it works well on most surfaces. Just apply a strip of tape along the edge of the vapor barrier where it meets the wall or floor.

– Use masking tape. This is similar to using painters’ tape, but it’s usually not as strong. It can work well on some surfaces, but not others.

– Use duct tape. This is a stronger option than either painters’ tape or masking tape, and it will work on most surfaces. Just be sure to press the duct tape firmly against both the vapor barrier and the surface beneath it.

– Use adhesive spray. This is another option that will work on most surfaces. Just spray an even layer of adhesive onto both the vapor barrier and the surface beneath it before pressing them together firmly.

What Tape Sticks to Tyvek?

For those unfamiliar with Tyvek, it is a synthetic fabric made of high-density polyethylene fibers. It is often used as a weatherproofing material or for packaging purposes. The question of what tape sticks to Tyvek is an important one, as the material can be difficult to work with.

There are a few different types of tape that can be used on Tyvek. Duct tape and gaffer’s tape are two options that will usually provide a good hold. However, it is worth testing the adhesive on a small area first, as some tapes can damage the surface of the fabric.

If you need a stronger hold, you can try using spray adhesive or contact cement. These products should be applied to both the Tyvek and the object you are attaching it to. Once dry, they will create a very strong bond that will be difficult to break.

As always, make sure to read all instructions carefully before use and test in an inconspicuous area first. With a little trial and error, you should be able to find a tape that works well for your needs.


There are many different types of tape that can be used for a vapor barrier, but not all of them are created equal. Some tapes are better than others at sealing out moisture and keeping your home or office dry. In this blog post, we’ll take a look at some of the different types of tape and see which one is best for use as a vapor barrier.
