How Do I Choose Weather Stripping

Choose weatherstripping that is durable, weather, temperature-resistant, and wear-resistant. When used on a door bottom or threshold, weatherstripping might scrape against carpet or erode as a result of foot traffic.

  • Window sashes must be constructed to slide smoothly up and down, sideways, or outward.
  • When the door or window is closed, the weatherstripping you select should seal well but enable it to open freely.
  • You’ll also need to pick a product for each distinct location.
  • Felt and open-cell foams are often low-cost, incommode, visible, and ineffective at blocking airflow.
  • The ease of application of these materials may make them appealing in low-traffic places.
  • Vinyl is a flexible and long-lasting material It looks great and is easy to clean because of its polished finish.
  • It does not hold moisture or mildew well, however it does not stain easily.

Metals (bronze, copper, stainless steel, and aluminum) last for years and are expensive. Metal weatherstripping can also provide a nice touch to older homes where vinyl might seem out of place.

What Types Of Weatherstripping Are Available?

Some seal better than others but they all have the same purpose which is to stop air from coming in or going out. There are three different types of common weatherstripping:

Expanding Foam:

This type of weatherstripping is best for small gaps. It comes in a can and you use a gun to spray it in the gap. When it dries, it will expand and fill the gap. It is easy to install and very effective when it comes to sealing air out.

  • It does take up some space in the door or window frame.
  • This can mean that your door or window may not close properly.
  • This type of weather stripping can be applied by hand and it expands to 3 times its size after the chemical inside the weatherstrip reacts with the air.
  • This is a quick-acting sealing system that can be used on doors that open inward, outward, and windows.

Metal-spring weather stripping

Metal-spring weatherstripping is used on doors that open inward and it has a metal strip that attaches to the door frame and a rubber seal that attaches to the door.


The cheapest option which makes them perfect if you are new to weatherstripping, it’s easy to install and is very effective.

  • This type of weatherstripping is available in different colors and thicknesses.
  • It can be used on almost any door.

The one thing you need to know is the usage and climate of the door or window. This will guide you on which one to use. If you’re not sure, it’s always best to ask a professional.

Which Type of Weather Stripping Is Best?

This question is difficult to answer as each person’s needs will be different. What works well for one home may not work out so well in another. The best thing to do is to evaluate the doors and windows, taking a look at what they have now and seeing how it’s working. Then you can start looking for products that will fit your needs.


The climate of your area will help you decide which type to use as the climate will determine what is best for your climate.

  • Dry climates are best suited for expanded foams while most other climates will suffice with vinyl.
  • If you live in a wet climate, then you should go with vinyl or rubber weatherstripping.
  • If you live in a windy climate, then you should use metal-spring weatherstripping as it is the most durable.

Not all weatherstripping is best for any window or door. The climate is important to understand in order to pick the best weatherstripping for your home.

Types Of Doors And Windows

The type of door/window you have will determine what type of weatherstripping you will need.

  • For sliding windows, some vinyl or metal-spring weather stripping with adjustable spring tension might be best.
  • A door jamb is a vertical surface at the bottom of a door where it meets the floor.
  • The edge of the door that contacts this surface must be sealed to prevent air leakage.
  • For a door with no weather stripping, you can use some silicone caulking to seal the joint.
  • Windows need weatherstripping on the top and sides as well as the bottom.
  • You can use a variety of weather stripping on a window, but it is important that you use something to seal the space between the window frame and the wall.

Windows that open, like casement windows, also need weatherstripping on the hinges. Weatherstripping is also available for storm doors.

Door Or Window Usage

How often the door is used will determine what type of weatherstripping you should use. For a door that is used often, you should use something durable, like metal-spring weatherstripping.

  • If the door is not used often, then you can use a less expensive option, like vinyl/rubber weatherstripping.
  • If the door is only used a few times a day, then you can use a less durable option such as felt or open-cell foam.
  • If the door is going to be used frequently, then you should go with a more durable and expensive option such as vinyl or rubber.

If the door or window that is being weather stripped will be used frequently, then it might be better to have a professional install the weatherstripping as there are many details required for a neat job.
