When you hear the word foam tape, you might think of packing foam or the kind that holds together your purchase in a box. That’s not all it’s good for, though! There are many uses for expanding foam tape, from insulating gaps to sealing drafts to soundproofing and more. Here are some of our favorite uses:

To Fill Gaps

Expanding foam tape can fill gaps. If you’re in need of a product to fill gaps and crevices, expanding foam tape is your go-to solution. It can fill gaps in wood, plastic—even gaps between the human body and its surrounding environment!

For example:

  • Expanding foam tape will be able to close off air leaks around windows and doors. That way, you won’t have to worry about drafts or energy loss during the winter months (or any other time of year).
  • It’ll also provide a barrier between people’s teeth during an oral surgery procedure. This helps them heal faster after surgery by providing protection from bacteria that might otherwise cause infections.

To Stop Drafts

When you’re trying to seal gaps, cracks and seams, expanding foam tape is a good option. It can provide a permanent seal that doesn’t allow air to pass through. Expanding foam tape is used for this purpose mainly for two reasons:

  • It’s easy to use. This type of tape isn’t difficult or time-consuming to apply, so it’s ideal for DIY projects and quick on-site fixes
  • It offers long-lasting protection against drafts. You don’t have to worry about reapplying your sealant every year when using expanding foam tape because it’ll last much longer than other types of insulation products

As a Sealant

Repairing a hole in your wall? Covering up the side of your guitar to protect it from the elements? Whatever the use, there are a lot of different things that expanding foam tape is perfect for. It can be used to seal off materials that expand when wet or heated, or which are sensitive to chemicals or UV light.

To Soundproof

Soundproofing is the process of reducing the amount of noise that one object or area makes when it comes in contact with another object or area. For example, soundproofing a room can reduce noise pollution and make your space more enjoyable to be in. Soundproofing also helps reduce sound from getting into or out of a room, which can help keep conversations private and ensure that you don’t disturb others with your music choices (or vice versa).

There are multiple ways to soundproof a room: acoustic insulation, dampening materials such as felt or foam rubber and mass loading products like drywall all contribute to this goal. You may need multiple solutions if only one is not sufficient enough; for example installing carpet on concrete floors can help reduce reverberation caused by footsteps while also reducing noise transmission through walls between rooms because each floorboard acts like an extra layer of dampening material added onto other techniques such as adding insulation boards behind walls instead using regular drywall sheets alone without any extra steps taken beforehand first before installation begins – making sure everything fits together properly before finishing work off!

For Insulation

Insulation is a material that reduces heat flow. This is done by either blocking the transfer of airflow, or by slowing it down. Insulating your home can help save you money on energy bills.

Insulation comes in many different forms:

  • Foam tapes are usually used as an adhesive to hold insulation in place while it’s being installed. They’re also used to seal holes and gaps, like around windows and doors.
  • Batts are thin pieces of foam insulation that are cut into strips or rolls, then wrapped around pipes or along walls and floors to provide a layer of protection from air infiltration (i.e., cold air coming in).

Expanding foam tape can be used for many purposes.

Expanding foam tape can be used to fill gaps, stop drafts and seal. It is also great at stopping sound from entering and exiting a building. This is because it acts like an acoustic barrier that stops sound waves from passing through or getting into your home.

It’s possible to use expanding foam tape for a variety of purposes:

  • To insulate the gap between double glazed windows (or any other kind of window)
  • To stop water leaks in roofs and walls


Now you know the benefits of expanding foam tape and how to use it in your home. If you’re looking to seal gaps and stop drafts, then this is the product for you! There are so many different kinds available on Amazon that it can be hard to pick one out from all those options. Hopefully by reading this article, we’ve helped make the decision easier for you.
