Factors to Consider Before Buying the Right Flashing Tape

Prior to ordering up windows flashing tape for your project, you need to consider certain factors. The factors are mentioned below. 

Types of Flashing Tape:

Flashing tape is a material that is used in construction to prevent water from entering a building. There are many different types of flashing tape, but the most common are made of acrylic, butyl, and bitumen.

Acrylic flashing tape is made of a plastic material and is the most common type. It is flexible flashing, weather-resistant, and easy to cut. They are recommended for use on vertical surfaces, but it can also be used for other applications where a strong cold weather-proof seal is needed.

Butyl flashing tape is made of a rubberized material adhering to polyethylene film. Flashing comes in rolls with an easy-to-remove film release liner. It is available in 20 mil thickness as well as a variety of sizes. It is most commonly used for sealing around window panes, wall assemblies, and other surfaces where the modified bitumen tape would be too rigid.

Bitumen flashing tape is made out of the same material as the rubberized asphalt used to seal roofs and roads, which makes it resistant to cold weather,  water, and UV radiation. It is also very sticky, making it a good choice for applications where a strong seal is needed. However, modified bitumen is also the most difficult to work with, as it is very stiff and hard to tear.

UV Protection:

Window flashing tape is essential for many construction projects. It is important to select the right type of window flashing tape, as some tapes are more effective than others against the sun’s UV rays. Sunlight can degrade certain tapes over time, so it’s important to find a tape that has UV protection built-in.


When purchasing flashing tape, it is important to find a tape that is not too thin or too thick. A thin tape may not be as durable as you need, while a thick tape can be difficult to install. You should use flashing tapes that are durable enough to last as long as your structure.

Weather & Temperature:

surrounding materials

Weather and temperature are two of the most important factors, as they can affect the adhesive on the tape. Most modified-bitumen products become less sticky at around 50°F, so they won’t stick as well in cold weather. If you’re working in cold weather, it’s best to choose a butyl or acrylic-based product.

When it comes to high temperatures, standard modified bitumen can often melt and ooze. This is especially true if it’s installed according to the manufacturer’s installation instructions and under metal that’s exposed to direct sunlight.  

For example, on metal roofing material or window framing that’s facing south or west.  When it comes to high temperatures, butyl tapes are more stable. But they too have upper limits.

Flashing tape can be ruined by high temperatures and high humidity. It is purposefully made of materials that will break from extreme heat and lose adhesive bond. So when it reaches the range of 120°F-180°F, the adhesive begins to soften and the film becomes less sticky. Commercial formulations are available with higher tolerances for heat, although they are typically not as sticky.


There are three main types of Materials: concrete, metal, and solid wood. Each type has its own set of pros and cons, so it’s important to select the right type of tape for the job

For example, if you’re working with concrete, you’ll want a tape that can avoid adhesive bond fails and can adhere well to wet surfaces. If you’re working with most metal flashings, you’ll want a tape that can withstand heat. And if you’re working with wood, you’ll want a tape that won’t cause any damage to the surface.


Is Flashing Tape Needed Around Windows?

Yes, you will need to use flashing tape to make sure the window is sealed. You can easily determine it by close inspection of the interior and exterior surfaces of the frame. Flashing is usually installed at the head, and sides of the windows.

Do Replacement Windows Need Flashing Tape?

The answer to this question depends on a few factors, such as climate and weather conditions in your area. If you live in an area with a lot of rain or snow, then it’s probably a good idea to use flashing tape on your replacement windows. 

This will help to ensure that moisture doesn’t seep into the window frame and cause damage to the new window.

How Wide Should Window Flashing Tape Be?

Because most window flanges have less than 2 inches in width, 4-inch tape will suffice to meet code requirements that flashing extend beyond the surface of the house wrap.

Is Acrylic Tape Water Resistant?

Acrylic adhesives are available in two types: water-based (also known as dispersion or emulsion) and solvent-based. While water-based acrylic systems are slower to dry than solvent-based ones, they have a better resistance to chemicals, solvents and water.

Final Verdict:

Window flashing tape is a durable, weather-resistant material for securing windows. It provides an airtight seal that prevents outside moisture from entering the home during storms or heavy winds while still allowing fresh air to flow in through open windows.
