WINDOWS Admitting natural light, permitting views to the yard and beyond, allowing natural ventilation—windows perform a number of critical roles in a building. And because of the wide range of jobs they must do, sometimes simultaneously, windows must be chosen thoughtfully and maintained with care.

Slide 4: 

WINDOWS Their work is often complex; for example, windows are expected to allow in light and views but keep out wind, rain, glare, cold, and intruders. To accomplish all of these tasks, windows must be designed with a range of features that work together seamlessly.

Slide 5: 

WINDOWS Of course, windows come in many shapes and sizes and are made of several different materials, from wood to aluminum to vinyl. Basically, all windows have frames and glass, and most have weather stripping. Windows used for ventilation have a means of opening and closing and may have screens to keep insects and debris outside.

Slide 6: 

WINDOW PARTS At first glance, a window looks like a pretty simple piece of equipment. It has a frame, glass, some basic hardware. But if you look a little closer, you'll find there’s much more than first meets the eye A window must be designed to allow in light and views and, in some cases, ventilation.yet seal out the weather. It must shed heavy rain without leaking and block powerful winds. And, if it’s operable, it must open and close easily. To handle these tasks effectively, it has many parts and a surprisingly complex construction.

Slide 7: 

WINDOW PARTS Window frames and sashes are built from wood, aluminum, vinyl, or a combination of these materials. Of these, wood is the best insulator and tends to yield the nicest look both indoors and out. Vinyl and aluminum are more durable and maintenance-free; some manufacturers apply a cladding of these materials to wood windows. The type of glass in a window has a great deal to do with how the window performs.

TYPES OF WINDOW BASIC TYPES OF WINDOWS ARE AS FOLLOWS

Slide 11: 

TYPES OF WINDOW 1.SLIDING WINDOWS Sliding windows have sashes that move horizontally on a track. Usually only one of the sashes moves and the other is fixed. Since only half of the window area can be opened, sliding windows provide less ventilation area than casement or rotating windows. An advantage is they are inexpensive, especially if the frame is aluminum, and easy to clean if the moveable sash is removed.

TYPES OF WINDOW 2.AWNING WINDOWS Awning windows, also known as hopper windows, swing open like casements but are hinged on the top or bottom rather than on the side. Some swing inward, others swing outward. Because they are easy to clean and provide more security than other types of windows, they are common in schools and in multifamily

Slide 15: 

TYPES OF WINDOW 3.ROTATING WINDOW Rotating windows open by pivoting around a central point. They allow good ventilation because in the open position, almost the entire window area is unobstructed. Because either side can face in, cleaning them is easy. Reflective coatings can be applied to one side of the glass and the homeowner can rotate the windows to reflect heat inward or outward as the season demands.

Slide 17: 

4.JALOUSIE WINDOW TYPES OF WINDOW Glass louvers that overlap one another form the panes of a jalousie window. Operated with a crank or turn-screw, the glass louvers tilt to open, permitting air flow. Besides the fact that they do not obstruct the view, their biggest advantage is they allow ventilation. A wall of jalousie windows can be opened to let breezes flow, making the indoors feel like outside.

Slide 18: 

This advantage however is also their greatest disadvantage -- they allow ventilation so well they are almost impossible to seal. When closed, each glass louver rests against the one below it, rarely if ever making an air-tight seal, and the hinges along the sides are almost impossible to seal without covering the entire window. They are not energy efficient and may be a security risk. Many building codes no longer allow jalousie windows. TYPES OF WINDOW 4.JALOUSIE WINDOW

Slide 20: 

Fixed-pane windows do not open, which means they do not permit ventilation or easy cleaning, but their sealed edges protect against air infiltration. Fixed-pane windows come in almost any size or shape and with single, double or triple glazing. In areas where heating or cooling is used much of the year, double or triple glazing should be considered for fixed-pane windows, especially if they are large TYPES OF WINDOW 5.FIXED PANE-WINDOWS

Slide 22: 

TYPES OF WINDOW 6.CASEMENT WINDOWS Casement windows open with cranks or levers that open them like doors. Older casements swing on hinges while newer ones have pivot mechanisms. Most swing outward, but models that swing inward are available. Casements provide excellent ventilation because both halves of the window open. Because they seal tightly when closed, they are considered energy efficient. Another advantage of casements is they are easier to clean than most other windows because both inside and outside surfaces are accessible from indoors.

Slide 24: 

TYPES OF WINDOW 7.DOUBLE-HUNG WINDOW Double-hung windows are probably the most common type of window. They open by sliding the bottom half of the window up or sliding the top half down. Because only half of the window area can be open at one time, they provide less ventilation than casement style windows. An advantage of double-hung windows is they can be used to create air movement in the home by opening the top portion of the windows on one side of the house and opening the lower portion of the windows on the coolest side of the house.

Slide 25: 

Air will naturally rise out of the higher opening, pulling cooler air in the lower opening. Older double-hung windows have weight-and-pulley systems to make them easier to open. Unfortunately, these systems tend to stick or rattle and it is hard to stop air from leaking around the pulley openings. Newer models have spring-tension devices and work far better.

8.SINGLE-HUNG WINDOW TYPES OF WINDOW Single-hung windows are similar in operation to double-hung windows, with the exception that only the bottom sash opens

Slide 28: 

TYPES OF WINDOW APART FROM THESES BASIC TYPES , WINDOWS ARE FOUND IN SOMEOTHER SHAPES AND STYLE ASWELL ACCORDING TO THE CONDITIONAL REQUERMENT. SOME OF SUCH TYPES ARE, ROUND-TOP WINDOWS BOW WINDOWS SEAMLESS BENT GLASS CORNER WINDOWS BAY WINDOWS GLASS BLOCK

Slide 29: 

Round-top windows and others that are geometrically shaped are used as architectural accents. 11.ROUND-TOP WINDOWS TYPES OF WINDOW

Slide 30: 

2.BOW WINDOWS TYPES OF WINDOW Bow windows project out like bays but have more than three sections that join to form a gentle curve. Center windows are generally fixed; side sashes are typically casement windows.

Slide 31: 

TYPES OF WINDOW 3.SEAMLESS BENT GLASS CORNER WINDOWS Seamless bent-glass corner windows are a fairly new product that offers unobstructed views at the corner of a house.

Slide 32: 

TYPES OF WINDOW 4.BAY WINDOWS Bay windows project out from the wall; a center window parallel to the wall is flanked by two windows attached at an angle, usually casement or double-hung styles. Box bays have side windows at a 90-degree angle.

Slide 34: 

TYPES OF WINDOW 5.GLASS BLOCK Glass block is a light-allowing alternative to conventional windows, used both in exterior and interior walls. Various patterns allow varying degrees of view or privacy. Typical sizes are 6-, 8-, and 12-inch squares and 4-by-8 and 6-by-8 rectangles made for 4-inch-thick walls.

Slide 36: 

A window isn’t just meant to bring light and views into a room. It may also define a room’s shape, provide an architectural focal point, allow ventilation, and/or provide for emergency escape. To serve widely varying needs, windows are made in a vast array of types and sizes that function differently. Broadly speaking, windows are either fixed or operable. Fixed windows are used mostly for accents or where light and views—but not ventilation—are important. Most round-top, triangular, and other unusually shaped windows are fixed, as are large picture windows. TYPES OF WINDOW OTHER ASPECTS

Slide 37: 

Operable windows may slide up, down, or sideways or they may hinge outward or inward. The windows shown represent most major types.Contemporary windows are available in a number of innovative styles. You can buy a bent-glass corner window, curved-glass windows, or casements with no center stile, for example. Some beautiful bow and bay windows, made up by combining fixed and operable units, are also common . TYPES OF WINDOW OTHER ASPECTS
