Types and styles of windows:
Wood Windows. Wood is the most versatile material for replacement windows: it can be milled or shaped to fit odd spaces and can be stained or painted to match your home's exterior and interior. Wood is a good insulator and is durable if properly maintained. Still, wood has that je ne sais quoi - few building materials that can compare with its natural beauty and warmth. For discriminating homeowners, wood remains a top choice. Wood accepts paint and stain readily, and its workability makes wood ideal for custom applications. When renovating a historic home and matching the style of older, existing windows, wood is the ideal choice.

Clad-wood windows
Clad-wood windows are made of wood but have a layer of vinyl, aluminum, or fiberglass bonded to the exterior, so they don't need to be painted or sealed. The interior, which is wood, can be painted or stained to match your décor. The bottom line, either vinyl or aluminum clad-wood windows can make an excellent and durable choice.

Vinyl windows
They're typically the least expensive and do not need to be painted or stained. Vinyl windows come in a wide range of interior and exterior colors, and can be ordered with an interior wood veneer that can be painted or stained.

Double or tripple-glazed, vinyl windows offer excellent heat and sound insulation. Old windows are often replaced throughout a house by new vinyl windows. More vinyl windows are sold than all other types of window construction combined - about 67 percent of the residential window market. That's because vinyl combines low cost with durability, reliability and energy performance. Vinyl is virtually indestructible, impervious to moisture and insect- and rot-proof. Vinyl is an inert material that's a poor thermal conductor, meaning it's a good insulator.

Fiberglass-frame windows
They're relatively new and while you won't have to paint them, they can be painted. Fiberglass needles embed the plastic to make it stronger and stiffer. The fiberglass material is fast gaining a reputation for being durable and blissfully maintenance-free. Combined with its middle-of-the-road price, fiberglass provides solid value. It's stronger than vinyl, and fiberglass windows won't warp, rot or crack. Also available: real wood interior frames and sashes that can be stained.

Where maximum light is required, aluminum windows can be an excellent option-the strength of aluminum means a thin frame can support a large expanse of glass. However, aluminum conducts heat out of the home and is prone to condensation. Old aluminum windows were prone to rust, but modern versions are coated during manufacturing and are durable and low-maintenance. Aluminum is extremely strong, meaning that windows can be fabricated with relatively thin frames and sash components. That provides more space in the window opening for glass and makes aluminum windows a favorite choice of architects. In addition, aluminum can be fabricated with an enormous variety of factory-applied color finishes that are extremely tough and long-lasting.

Double-hung windows
A popular choice, the lower inside sash slides up and an upper outside sash slides down. Double-hung are easy to clean since you can tilt the sash on any of the tested windows. They're also a smart choice if you plan to install a window air conditioner.

Single-hung windows
They look like double-hung but usually cost less and only the bottom sash moves. Single-hung do not have the ventilation benefits of double-hung but are good if you want to install window air conditioners.

Casement-style windows
Providing an unobstructed view, casement windows are hinged on one side, like a door, and a crank lets you open them outward. When fully open casements allow for good ventilation and easy cleaning. They're usually more airtight than double-hung because the sash locks against the frame to close.

Awning-style windows
They're hinged at the top and open outward. Like casements the sash presses against the frame so they close very tightly. They also offer better ventilation than other windows the same size and can be left open when it's raining since they deflect rain.

Hopper-style windows
The opposite of awning windows, they're hinged at the bottom and can open either inward or outward. They're often installed above a door or another window to improve ventilation.

Fixed windows
These are used where lighting but not ventilation is important.

Make Mine Energy Efficient
Features such as argon-filled glazing and low-E coatings have become commonplace. The window's U-factor and solar heat gain coefficient must both less than or equal to 0.30. The U-factor gauges the window's insulation value, and the solar heat gain coefficient measures how well a product blocks heat transfer from sunlight. These measurements are standardized by the National Fenestration Rating Council and appear on the product's NFRC performance label.

Double or triple glazing
Double-glazed windows have a sealed space between two panes of glass filled with air or gas. Gas provides better insulation and is standard on most of the windows. Triple-glazing adds a third layer of glass, which reduces noise significantly and energy savings are improved especially with Low-E coating.Low-E coating It's transparent and improves the efficiency of the glass by reflecting heat yet letting light in. The coating is applied to the outside glass in warmer climates to reflect the sun's heat out and in colder days to keep heat in. Tilt-in sashes On single and double-hung windows the sashes (the moving part of a window) can be tilted in for easy cleaning. Nearly all brands have this feature.

Grilles and Divided Lites
Windows divided with smaller panes were historically easier and much more affordable to produce than large sheets of clear glass. Today, even though technology allows us to create larger panes of glass that are much less expensive, the traditional look has become very popular. The smaller panes of glass in a window are called divided lites. They are separated by strips of wood called grilles. True divided lite windows are manufactured in the traditional method with a solid wood frame broken into shapes with wood strips. Grilles are a popular choice on newer homes' windows. Adding a touch of historic style, grilles are offered in the same material as your window frame. If you would like the look of a divided lite window, but are not concerned about having true divided lites, manufacturers offer detachable grilles. These provide the same look as the true divided windows, but are available at a lower cost. With detachable grilles you also have the option of removing them and cleaning behind the grilles when necessary.
