We know weatherizing your home is important, and that sealing gaps around windows and doors can save both energy and money. Unfortunately, the options at the hardware store can be a little overwhelming. I wasn't quite sure what to buy a few years back, so I grabbed some clear packing tape I had laying around to seal my windows. Not a pretty sight come spring. This Old House
lists the most common weatherstripping options, and where they go:
1. V Strip (Tension Seal):
v-shaped plastic or metal strip that springs open to bridge gaps. Self-adhesive that can be applied along the sides of a double-hung or sliding window, and on the top and sides of a door.
plain or reinforced with a pliable metal strip. Must be stapled or nailed around a door or window sash, or in the door's jamb so that it compresses against the door.
3. Foam Tape:
made from open or closed-cell foam, or EPDM rubber. Because it comes in a variety of widths and thickness, it's good for irregular sized cracks in the top and bottom of window sashes, and inside door frames.
4. Door Sweeps
: made from flat pieces of plastic, aluminum, or stainless steel, and fitted with a strip of material to fill the space between the door and threshold. Place on the botton of the interior side of the door.
5. Tubular Rubber, Vinyl, or Silicone:
sponge rubber or vinyl tubing come attached to a wood or metal mounting strip. Silicone versions are usually inserted into milled grooves. Effective air barrier when placed at the base of doors and windows, top or bottom of a window sash, bottom of a door, between a door and its jamb.
Weatherstripping should be applied around movable joints, such as windows or doors, and when installed properly, it provides an air-tight seal. According to the US Department of Energy
, you can determine how much weatherstripping you will need by adding the perimeters of all windows and doors to be weatherstripped, plus 5%-10% to accommodate any waste.
