The Benefits of Weather Stripping

HandymanAs houses age, they can develop small cracks along seams in windowsills, door frames, and attic spaces. These tiny cracks can have a major impact on your energy costs. Air seeps through these cracks, causing your home to lose 30 to 40% in extra heat in the winter and cooled air from your air conditioner in the summer. One way to combat this issue is to weather strip your house.

What is Weather Stripping?

Weather stripping is taking a material such as sponge, foam, felt, rubber, vinyl, or metal and using them to fill in the gaps formed by these cracks. Soft materials like sponge, foam, and felt are generally the most inexpensive, but are also the least durable materials. Vinyl is a very common weather stripping material, being that it is fairly durable and resistant to moisture. Metals such as copper, stainless steel, and aluminum are often used in conjunction with other materials to help reinforce them. These materials will prevent air, dust, and insects from passing through the gaps between windows and their sills or doors and their frames. It is important to seal the gaps on doors that lead to attics, basements, and garages as well as those leading outside, as these rooms can be prone to air leaks.

Types of Weather Stripping

  • Pliable Gaskets – These rubber seals can be applied to door and window stops or to window sashes.
  • Rigid Strip Gasket – These thin strips of vinyl, felt, or foam can be attached to wood or metal strips and affixed to window and door frames.
  • Door Sweep – A metal strip with sponge, vinyl, felt, or brushes is screwed into the bottom of the door and is particularly useful for doors that lack or have a low-profile threshold.
  • Door Shoe – A similar design to the door sweep, this aluminum and vinyl strip is again affixed to the bottom of the door and maintains a seal with doors that have a higher profile threshold.
  • Folded Strips – Metal or vinyl strips laid in window channels or between the door and jamb help seal most gaps.

Installing weather stripping is relatively easy to do. Some materials even have self-adhesive options, requiring only a clean, dry surface to attach to. Others may slide into place or require some glue, screws, or nails. It is recommended you follow the manufacturer’s directions when weather stripping your own home.
