Choosing Window Types
Is it time to install a new window? With cold winter on the way, this is a great time to make sure your house is insulated against wet, cold and wind. But with all the window types out there, which one is best for your house?
In this post, we'll take a look at the most common window types, glazing and coating. Remember that Last Call Exteriors can help with all your window purchase, installation and repair needs.
Popular Window Styles
Single-hung and double-hung windows. These operate with a sash that allows the window pane to slide up and down. Single-hung windows move up and down only. Double-hung windows, as the name implies, have two sashes. The double hanging allows the window to slide down and toward the user, making it easy to clean because you don't have to go outside to wash the outside pane.
Single-hung and double-hung windows are a popular style. They work in most homes and are available in a wide selection of frame styles. They are not as airtight against leakage as hinged window styles.
Awning window. As the name implies, this window is styled like a classic awning. It is a hinged-style window that opens outward from one fixed sash at the top. Awning windows are good at blocking leaks.
Hopper window. Like the awning window, the hopper window is a hinged style that opens outward, only from the bottom instead of the top.
Awning windows and hopper windows are sometimes used as transoms over doors or along the side of picture windows. They're a good choice for rainy climates because they allow air circulation without letting rain into the house.
Jalousie window. This window type is commonly seen in sunrooms and patios. It features louvered glass or acrylic louvres set in a frame. The louvres can be moved up and down to change how much air and light get in.
Jalousies are a good choice for mild climates where air conditioning and heat aren't used that often. They provide excellent ventilation but they don't offer clear viewing.
Casement window. A casement window swings open sideways with the use of a hand crank. These windows close by pressing against a fixed sash, similar to the closing mechanism of an awning or hopper window. Casement windows are gaining in popularity. They are highly energy-efficient and excellent at reducing leakage. The crank also makes them easier to operate than double-hung or single-hung windows.
Picture window. This is a large, fixed window that doesn't open and allows a lot of natural light into the home. A picture window allows a beautiful outdoor scene to take center stage in a room. Picture windows are dramatic and flood the room with light, but you have to remember to use curtains or other filtering devices if the sunlight gets too strong.
Glass and Glazing Types
In addition to deciding on your window style, the type of glazing and glass you buy is key to knowing whether your window will help you retain heat, retain coolness and reduce your energy bills. Adding specific coatings will fine-tune the performance of your windows.
Single glazing. This type of glass allows the most light in. That may sound good, but it reduces the window's energy efficiency. You'll spend more money trying to keep your house cool with this type than any other.
Double glazing. This type of window features two panes of glass with some type of filler or gas between them. Double-glazed windows are twice as energy-efficient as single-glazed windows.
Triple glazing. In windows, the heat loss rate is called the U-factor. Windows with a low U-factor retain the most heat. Triple-glazed windows have very low U-factors. This makes them ideal for extremely cold climates where heat retention is important.
Coatings and Special Functions
Windows now come with a range of innovative coatings and filler gases that improve their performance and energy efficiency.
Low-emissivity (low-e) coating. This is an extremely thin metal or metallic oxide layer that is applied to the glass. A low-e coating can reduce energy bills up to 50 percent.
Spectrally selective coatings. This type of coating filters out the strongest, most harmful ultraviolet rays from the sun. At the same time, it admits the full amount of light into the house. This type of coating is ideal in locations with hot summers. It can cut air conditioning bills in half.
Gases and Fillers
Krypton and argon. These lightweight, odorless gases are the most commonly used gases between glass layers.
As you can see, there are a lot of things to consider when selecting windows, and we can help you make the right choice. Last Call Exteriors can replace your windows quickly and safely. Get ready for cold weather with windows that are properly insulated and energy-efficient.
