|Window Weatherstripping for Replacement Windows|
|Adequate weatherstripping will ensure that replacement windows do not leak air =|
Weatherstripping is used to seal air leaks around an operable window. Sealing air leaks around non operating windows involves caulking cracks and gaps.Weatherstripping protects a window from air penetration but absorbs a significant amount of wear and tear. Weatherstripping seals should be checked annually for signs of damage or deterioriation and replaced as necessary.
 Weatherstripping Window Seals
Weatherstripping is a vital component of an operable window. It creates a seal between the window-frame and the operable sash which prevents air leakage. A replacement window's performance is partially determined by the performance of the weatherstripping seals. There are a wide range of categories of weatherstripping designs including tension seals, felt seals, reinforced foam seals, taped seals, reinforced vinyl seals, wiper/brush seals or magnet seals.
 Tension WeatherstrippingSeals
Tension weatherstripping seals are self-stick plastic (vinyl) seals which are folded in a V shape. The shape creates a seal by pressing against the sides of a gap to block a draft. Tension seals are installed inside the track of a sliding or double hung window. They are moderately priced and present a durable and effective weatherstripping option. Tension weatherstripping seals are relatively easy to install. All surfaces must be smooth and flat when installing tension weatherstripping and the corners must sit snuggly in the track.
 Felt Weatherstripping Seals
Felt weatherstripping seals include a flexible metal strip which are stapled, tacked or glued into place. They can be installed anywhere around a window's perimeter. Installation is simple. Felt weatherstripping seals are a low-cost weatherstripping solution but are not particularly durable and not very effective in preventing drafts.
 Reinforced Foam Weatherstripping Seals
Reinforced foam weatherstripping is a foam seal which is attached to the wood or metal that sits around the perimeter of the window. Foam is an inexpensive and effective weatherstripping option but foam seals can be difficult to install as they must be nailed, sawed and painted to fit properly.
 Tape Weatherstripping Seals
Tape weatherstripping seals are closed-cell, open cell or rubber seals which are installed on the bottom and top of a window sash. They are particularly effective at sealing corners and irregular cracks which present a low-cost weatherstripping solution that are easy to install and effective when compressed. They must be replaced relatively frequently
 Reinforced or Rolled Vinyl Weatherstripping Seals
Reinforced or rolled vinyl weatherstripping is installed at the bottom of a window sash. Rolled/reinforced vinyl weatherstripping seals are relatively inexpensive and easy to install. The installation involves applying the self-adhesive vinyl strips around the perimeter of most window frames -- reinforce or rolled vinyl weatherstripping seals may not adhere well to metal.
 Magnetic Weatherstripping Seals
Magnetic weatherstripping seals are extremely effective sealers. They are generally installed on the tops and sides of double hung and horizontal sliding window applications. They are one of the more expensive weatherstripping seal options.
 Wiper or Brush-Type Weatherstripping Seals
Wiper or brush-type seals are mostly seen in horizontal sliding windows or on large casement windows such as component windows of a bay window or a bow window. They include aluminum or stainless steel seals with plastic, vinyl, sponge, or felt brushes that sweep along the bottom sash as the window opens or closes. They wear out quickly due to the type of window operation and are more likely to be used for exterior weather seals. These types of weatherstripping can tear easily if the window is open while there is ice on the seals.
 Choosing the Right Weatherstripping
Different types of weatherstripping are applicable for different climates and different window styles. In general, homeowners should select a type of weatherstripping that will withstand the weather, friction temperature changes, and wear and tear that is common in its location. Weatherstripping along a window sash must match the panes' sliding motions, either up and down, sideways, or outswing. The weatherstripping should seal well when the window is closed but allow the window to open easily. More than one type of weatherstripping may be used to seal an irregularly shaped space.
