What Types of Weatherstripping are Best? | Blog
Weatherstripping is one of the household materials that keeps warm air inside in winter and hot air outside in summer. Usually foam, vinyl or rubber, it’s typically installed to close the gap between two moveable surfaces. Weatherstripping is usually found along the edges of a door and the door jamb to form an effective seal against air leakage when the door is closed. It’s also usually present on the bottom of the door to close the gap between the door and the threshold. Weatherstripping is also found on double-hung windows to seal between the sash and the window frame and between the central V-channel and the sash.
Because weatherstripping is placed between two moveable surfaces, as the door or window is opened and closed friction and wear occurs over time and replacement is normally required. Here are several common types of weatherstripping.
- Peel-and-stick foam. This is the least expensive option and also the easiest to apply. Typically made of non-porous closed cell foam it can be used around door frames, on the top and bottom window sashes and to seal attic hatches and small openings. Foam typically wears away fastest due to friction and will need to be replaced more often.
- Self-adhesive rolled vinyl. This is pliable material that can be stuck to most door frames and window sashes, but may not adhere well to metal surfaces. Its cost is low to moderate and durability exceeds foam but is not as good as other options.
- Tubular vinyl or rubber. Compresses as the door or window closes against it to form a very effective air seal and is very durable. Usually it must be manually stapled or tacked in place—not self-adhesive—and the cost is moderate to high.
- Door sweep. Installed to close the opening beneath the bottom of a door and the threshold, it consists of an aluminum or stainless steel plate with a brush made of vinyl or rubber to seal the gap. Door must be removed for installation. Cost is moderate to high.
