Weatherstripping comes in many forms, such as felt, open-cell foam, vinyl and metal, and each has a specified purpose. The Department of Energy has compiled the following information about different types of weatherstripping and their characteristics.

 Weatherstripping  Uses  Pros  Cons
 Tension seal:
Self-stick plastic (vinyl) folded along length in a V-shape or a springy bronze strip (also copper, aluminum, and stainless steel) shaped to bridge a gap. The shape of the material creates a seal by pressing against the sides of a crack to block drafts.
 Inside the track of a double-hung or sliding window, top and sides of door.  Durable. Invisible when in place. Very effective. Vinyl is fairly easy to install. Look of bronze works well for older homes.  Surfaces must be flat and smooth for vinyl. Can be difficult to install, as corners must be snug. Bronze must be nailed in place (every three inches or so) so as not to bend or wrinkle. Can increase resistance in opening/closing doors or windows. Self-adhesive vinyl available. Some manufacturers include extra strip for door striker plate.
Plain or reinforced with a flexible metal strip; sold in rolls. Must be stapled, glued, or tacked into place. Seals best if staples are parallel to length of the strip.
 Around a door or window (reinforced felt); fitted into a door jamb so the door presses against it.  Easy to install, inexpensive.  Low durability; least effective preventing airflow. Do not use where exposed to moisture or where there is friction or abrasion. All-wool felt is more durable and more expensive. Very visible.
 Reinforced foam:
Closed-cell foam attached to wood or metal strips.
 Door or window stops; bottom or top of window sash; bottom of door.  Closed-cell foam an effective sealer; scored well in wind tests. Rigid.  Can be difficult to install; must be sawed, nailed, and painted. Very visible. Manufacturing process produces greenhouse gas emissions.
Nonporous, closed-cell foam, open-cell foam, or EDPM (Ethylene Propylene Diene Monomer) rubber.
 Top and bottom of window sash; door frames; attic hatches and inoperable windows. Good for blocking corners and irregular cracks.  Extremely easy to install. Works well when compressed. Inexpensive. Can be reinforced with staples.  Durability varies with material used, but not especially high for all; use where little wear is expected; visible.
 Rolled or reinforced vinyl:
Pliable or rigid strip gasket (attached to wood or metal strips.)
 Door or window stops; top or bottom of window sash; bottom of a door (rigid strip only).  Easy installation. Low to moderate cost. Self-adhesive on pliable vinyl may not adhere to metal; some types of rigid strip gaskets provide slot holes to adjust height, increasing durability. Comes in varying colors to help with visibility.  Visible.
 Door sweep:
Aluminum or stainless steel with brush of plastic, vinyl, sponge, or felt.
Bottom of interior side of in-swinging door; bottom of exterior side of exterior-swinging door.  Relatively easy to install; many types are adjustable for uneven threshold. Automatically retracting seeps also available, which reduce drag on carpet and increase durability.  Visible. Can drag on carpet. Automatic sweeps are more expensive and can require a small pause once door is unlatched before retracting.
Works similarly to refrigerator gaskets.
 Top and sides of doors, double-hung and sliding window channels.  Very effective air sealer.  
 Tubular rubber and vinyl:
Vinyl or sponge rubber tubes with a flange along length to staple or tack into place. Door or window presses against them to form a seal.
 Around a door.  Effective air barrier.  Self-stick versions challenging to install.
 Reinforced silicone:
Tubular gasket attached to a metal strip that resembles reinforced tubular vinyl
 On a doorjamb or a window stop.  Seals well.  Installation can be tricky. Hacksaw required to cut metal; butting corners pose a challenge.
 Door shoe:
Aluminum face attachment with vinyl C-shaped insert to protect under the door.
 To seal space beneath door.  On the exterior, product sheds rain. Durable. Can be used with uneven opening. Some door shoes have replaceable vinyl inserts.  Fairly expensive; installation moderately difficult. Door bottom planning possibly required.
 Bulb threshold:
Vinyl and aluminum
 Door thresholds  Combination threshold and weatherstrip; available in different heights.  Wears from foot traffic; relatively expensive.
 "Frost-brake" threshold: Aluminum or other metal on exterior, wood on interior, with door-bottom seam and vinyl threshold replacement.
 To seal beneath a door.  The use of different materials means less cold transfer. Effective.  Moderately difficult to install, involves threshold replacement.
 Fin seal:
Pile weatherstrip with plastic Mylar fin centered in pile.
 For aluminum sliding windows and sliding glass doors.  Very durable.  Can be difficult to install.
 Interlocking metal channels:
Enables sash to engage one another when closed
 Around door perimeters.  Exceptional weather seal.  Very difficult to install as alignment is critical. To be installed by a professional only.
