6 things to know before getting your windows replaced

Windows enhance the façade of a house, shielding it from environmental elements like noise and pollution. Homeowners seldom think about the logistics of window replacement unless they have owned the house for a number of years. Windows might need replacement if they are of outdated style, or vulnerable to air or thermal leaks and water infiltration. The following article lists some things that you should know before getting your windows replaced:

Window glazing
Window glazing is done to create a barrier to heat flow. Most windows typically have two layers of glass called a dual or double pane. There is a small gap between the two glass panes, which is typically enhanced with an additional layer of glass, making the windows triple-glazed. The gaps between these layers are filled with a combination of argon or krypton gases that further reduces heat flow by conduction. Most windows may only require window glazing which can be more cost energy and cost efficient than complete window replacement

Replacement versus repairing
Some windows may only require repairing in the form of glazing. In other cases, window panes may remain intact and the areas around the window may require repairing. Window frames or sills receive the most amount of environmental brunt in the form of heat and moisture. So, if the area around the window is rotted to the extent that it does not appear structurally sound, then it is highly recommended that you consider replacing the entire frame.

Performance enhancers
The following types of coatings or materials can protect your windows from excess light and heat:

• Tinted glass
  Tinted glass consists of materials that reduce its transparency. Bronze, grey, and green tinted glasses especially block excess radiant energy, thereby keeping the indoors cool. Tinted glass can reduce transmittance by almost 60 percent.
• Reflective films
  Reflecting film window glasses have the same function as tinted glasses. They keep the indoors cool and block most of the visible light by giving windows a mirror-like appearance. However, this may increase electricity consumption, as lights may be used to compensate for the loss of daylighting.
• Low-e coatings
  These are more effective and versatile than both tinted glasses and reflective films. In this procedure, glass is infused with microscopic metal or metallic oxide particles that suppress radiant heat flow. Windows with low-e coating can also help trap the heat indoors. This can be helpful in areas with cold temperatures. Low-e coatings can be adjusted according to the window’s solar heat gain coefficient (SHGC).

Types of replacements services
The best window replacement companies offer three types of window replacement services:

• Retrofit windows
  These are also referred to as inserts that fit comfortably inside the existing window frames. Existing moulds are not affected, as only old sashes and window stops are removed. However, this is only an option for old window frames that are rot-free or in good condition.
• Sash-only replacement kits
  This type of low-cost window replacement is done only when the sash and jamb liners need to be replaced.
• Full-frame replacement
  This is typically done when the window is deteriorated beyond repair or if a different style of window or frame is required. It involves the removal of the entire existing window, requiring more labor and cost.

Window replacement cost
On an average, the cost of repairing windows can be anywhere between $500 to $2,000. The pricing depends on several factors, such as the extent and type of replacement, the expertise of the personnel, and materials used, among others.

Best window replacement services
Choosing the best window replacement companies can help save money annually. However, it is important to pick companies that focus on energy savings. Renewal by Andersen is one of the best overall window replacement companies, and has installed at least three million windows in both residential and commercial spaces. Champion Windows and Home Exteriors is another well-known residential window replacement company. Window World and Glass Doctor are also two of the nation’s leading companies for window replacement.
