Why Weatherstripping Is Even More Critical in Summer

by Geoffe Browne on Jul 9, 2020 9:01:00 AM

 Weatherstripping is important year round, but it's even more critical in hot weather. Now that summer is here, all your doors and windows should be tightly sealed to prevent heat from escaping into your home. In addition to overheating your house, gaps in windows and doors can lead to paying high energy bills. Here's what you need to know about weatherstripping, along with what to consider when deciding on a product.

What Is Weatherstripping?

You've probably heard of weatherstripping but may not understand what it really is. Put simply, weatherstripping is the process of sealing openings or gaps around doors and windows that require a tight seal. Weatherstripping can also get rid of a draft or air flow from an inside space to an outside space. That's why weatherstripping is usually included on doors and window sashes for permitting better cooling or heating.

Types of Weatherstripping Products

Weatherstripping comes is several forms, including:


Sold in rolls, felt weatherstripping is inexpensive. But It generally lasts for just one to two years. This form of weatherstripping goes around window sashes or around doors as well as in door jambs. Installation is easy as it involves cutting it to a desired length, using a utility knife. You can either nail or staple felt weatherstripping.

Foam Tape

The advantage of foam tape is that it works well for cracks with an irregular size. Foam tape is from EPDM rubber and has a sticky back. It comes in various thicknesses and widths, and installation is easy. Just cut the tape to a desired length and then stick it where needed.


This form of weatherstripping does an exceptional job of blocking air. Although it can cost more, vinyl is incredibly moisture resistance, so it does well in areas prone to a lot of humidity and moisture. It's typically installed at the base or windows or doors, on the bottoms or tops of window sashes and on the bottoms of doors. It can also be used as an air barrier between a door and the door's jamb.

Vinyl weatherstripping is installed by peel and stick. Another installation method is by fastening it with screws, using slot holes.


Bronze, stainless steel, copper, aluminum and other metal weatherstripping are not only affordable but can last for several years. What's more, metal can enhance the look for an older home in which vinyl looks out of place.

A disadvantage is that metal weatherstripping can be harder to install. Because there are a wide range of metal stripping, with some of them being more complicated, it's best to have the installation done by a professional.

Tension Seal

This is a vinyl plastic weatherstripping. Because tension seal has a "V" shape, it's also known as V strip. This form of weatherstripping is an exceptionally strong metal or plastic strip that bridges gaps by springing open. It's used on sliding or double-hung windows as well as on the sides and tops of doors.

Installation is rather simple. Using scissors, cut the length you need. Next, you can peel and stick the product or use finishing nails.  

What to Consider When Buying Weatherstripping

  • Cost and durability—The cheapest types of weatherstripping are felt, sponge and foam. On the other hand, they're less durable.
  • Consider the location where the weatherstripping is to be installed
  • Besides the size of the gap, also consider the evenness of the gap.
  • Another consideration is whether the product is easy to install. But even if you're not that handy, most homeowners can easily install weatherstripping by watching DIY videos.
  • Consider whether it's important if the weatherstripping is visible. While some weatherstripping is obvious, other types can be hidden.
  • Consider weather exposure, besides wear resistance by friction or abrasion.
  • Consider that weather stripping comes in various lengths and depths.
  • When determining the amount of weatherstripping needed, calculate the perimeters of all your doors and windows. Next, add five to ten percent for accommodating any waste.

Other Considerations and Warnings

Be sure the surface to which you're applying the weatherstripping is dry and clean.
