The size and shape of a window generally depends upon the activity performed in a room. The top of the door and windows are in the same level and the sill level of the window is usually about one metre above the floor level. The window comprises of the following parts as depicted in the image given below. Frame Window Frame is the open structure that holds the window panes as border. Head It is the horizontal part forming the top of the window frame. Grilles

Movable windows They are more familiar, versatile as they provide light, view and control climatic conditions. Major types of movable windows are Double hung windows Horizontally sliding windows Casement windows Awning and projected windows Jalousie windows Bay Windows Ranch or stripe windows French windows
Double Hung Windows These windows have two sashes that slide up and down. The frame of the window is usually moveable in which the panes of glass are set. They are easy to install, less expensive and are long lasting. These windows can be opened from top or bottom. The major disadvantages are that not more than half the area can be opened and there is no protection from rain. Apart from this, it is difficult to clean from inside unless the sash is removed. It is also inconvenient to operate when huge furniture is placed underneath. Horizontally sliding windows They are similar to double hung windows, which are made of shutters, which can be moved horizontally or vertically on small roller bearings. They are simple in design, easy to operate and have more longevity. The disadvantages of these windows are that they reduce air flow and difficult to clean from outside.

Operation and cleaning of the window is easy. They also have some drawbacks like they interfere with furnishings and offer no protection from rain. Tight weather proofing is difficult in these windows. Awning and projected windows They are similar to casement windows, hinged at the top and rarely at the bottom. These windows provide an attractive contemporary look, good ventilation, light and are a good choice in damp climates. The main drawback of these type of windows have more to do with maintenance issues and location than construction.
Jalousie windows Jalousie windows are made of narrow strips of glass. Apart from the advantages of awning type windows, they also take little space, appear in odd shapes, and are less expensive The drawbacks of Jalousie windows is that it is difficult to clean and small panes of glass does not give full outside view. treatment difficult. Bay Windows Bay Windows projects outside the external wall of a room They are large curved windows designed to fit a given space or a group or three of more windows placed at an angle to each other. The window projects outside the external walls to a projection called as a bay. These windows are more versatile, allow natural light to enter the rooms and provide good ventilation. The unique configuration of these windows make window Ranch or stripe windows The ranch windows are made of horizontal window strips fixed on sliding or swinging casement. These windows are wide and set high in a room to allow space for furniture and to provide privacy. The position and proportion often make window treatment difficult. French windows French windows are made of glass doors that open like casements often into a yard or terrace. They differ in style and have single or double door with small windows either at the side or above the door. They are generally left undecorated but when privacy is needed, special methods are employed.
Fixed Windows They are more familiar, versatile as they provide light, view and control climatic conditions. Major types of fixed Windows are Bow Window Picture windows Dormer Windows Clerestory Windows Skylights Arched Windows Round and octagonal windows Semi-circular windows Corner windows Bow windows These are curved windows having the same problems as the bay window.

For example, a darker shade of a particular colour is used in these windows if walls of the rooms are finished in a single colour.
Clerestory windows These windows are set high on a wall between two roof levels. Without reducing the wall space, more light is permitted inside the room as they are placed high on the wall. They generally save solar energy and hence widely used as a passive building design element.glare alone should be taken into account while designing these windows. Skylights Natural light like sunlight and moonlight are let inside the room without hindering privacy. They are set on roofs. Light can be reduced by sheer or net curtains.

Window Treatment In a room, windows along with the walls, floors and ceiling form the layout of a room. Treatment to windows can cover faults, create illusion or become a focal point of a house. They provide a large unit of colour, texture and styling in a room. The size of the room plays an important role in deciding the window treatment. If the room size is small, then the treatment to the windows should be more than the size of the window, light in colour and simple in style in order to make it proportionate to the size of the room. Window treatment is classified as exterior window treatment and interior window treatment. Exterior window treatment The purpose of Exterior window treatments is to protect the windows from extreme climatic conditions and therefore they are less emphasised and not decorative. Some of the exterior window treatments are: awnings or shades Blinds shutters grillers overhanging roofs

Ruffled Curtains or Priscilla Priscilla curtains also called as ruffled curtains are generally decorated at the top with a ruffled valance. These curtains are known for the softness and feminity. These sheer curtains are usually short just covering the bottom of the window frame or up to floor length. Casement Curtains These curtains are generally used on casement windows that open inwards and on French windows and doors.

Generally the shape of the valance may be like the original line of a window or may be curved to fall on both sides of the window. The curved depth is made in proportion to the height of the window Draperies To produce a quick, simple and stunning idea for windows is to treat them with asymmetrical draperies. They are made of medium or heavy weight fabrics to prevent the entry of light and heat into the room. It generally extends from the top of a window up to the sill or 9 to 12 below the sill. The draperies are made with pleated headings and are usually fixed to the rods by hooks and rings. Selection of window treatment The following are the factors to be considered while selecting furnishing materials for treating windows Style: The style of furnishing a room affect the lines of the window treatment. Today we find curtains with bright prints, stripes and checks woven in bold patterns with beautiful colours. In a living room with formal settings, it is preferable to have full-length draperies of opaque materials. Traditional rooms look good with the use of luxurious fabrics like damask, brocade or velvet whereas modern rooms are generally made of plain coloured fabrics. The visual effect is provided by the fabric texture and heavy linings, for example, heavy silk or white jacquard weaves with simple patterns. In an in-formal settings, like cottage type living rooms, ornamental draperies and opulent fabrics are used. Pattern Though plain curtains are common, the patterned ones are more popular as they provide variety and a higher aesthetic value. The pattern can also be overall pattern, small neat pattern, bold sharp pattern, floral pattern and geometrical pattern. Decorative patterns are generally produced by weaving, embroidery, or printing patchwork.
Patterns provide some effects in a room. A wide upright striped pattern make the wall look higher and stripes across make the room look wider. The size of the room should also be kept in mind while selecting the type of pattern in selecting window treatment. Texture Difference in textures make a room very interesting and provide a good feel in the room. Certain textural qualities are related with particular colours for example bright gold and purple denotes luxury and elegance of textures when used in correct proportions Rooms that are delicate require fabrics like silk, satin, chiffon, taffeta, velvet etc. Whereas Sturdy rooms need natural cottons, fish net, casement cloth, voile, gauze, organdy, coloured sheeting, handlooms fabrics etc. Modern rooms can use either the new sleek shiny composition fabrics or the boldly textured novelty weaves or polyester blends which can provide contrast for smoothness. Other fabrics and weaves are terry, pebble weave, jersey, cheese cloth etc. which are also found in the modem market. Window treatment in bathrooms like shower curtains are made of rubber, plastic or cellophane sheets Proportion Taking the line and proportion of a room into consideration while choosing window treatment, use of valances or horizontally placed pelmets in rooms with high ceilings will produce an appearance of reduced height. Another factor to be considered is the number of windows and similarity in treatment of these windows so that they appear as a single unit. Fashion Fashion keeps on changing and to meet the challenges in the modern world one must be alert by visiting shops, exhibitions, fairs etc. Plain coloured fabrics tend to be fashionable at one time, and patterns are in fashion at other times. Durability Depending upon the function of the room and the amount of usage, materials chosen for window treatment changes. For example, cotton draperies get bleached by the effect of sunlight which affect the durability of the fabrics. Though certain draperies like velvet and jacquard are expensive, they are long lasting and therefore they should be bought with consideration. Imitation of costly fabrics such as cheap satin, artificial silk and damask can be avoided as it spoils the entire look of the room and proves to be uneconomical in the long run. Personality and personal preferences Window treatment also depends on the personality and the likes and dislikes of a person who uses the room. Colour Colour harmonies are brought in a room by use of colours in window treatment Finely related colours in curtains and draperies are essential for creating harmony and beauty.when rooms are treated with numerous colours, window treatment should depict these colours to unify them.
Cost For most of families, the important factor for consideration is the budget allotted for window furnishings.. The cost of fabrics for curtains might be less as compared to the expenditures for other furnishings, because they need to be changed every often. Care and cleaning of window treatment The rod and track of windows must be kept free from dust by the use of a vacuum cleaner The curtains and draperies must be shaken often to keep it free from dust Repairs to linings, frayed edges and any difficulty in pulling the curtains, blinds etc. should be dealt appropriately. Exposure to sun must be minimized by reversing the position Lined curtains are generally dry cleaned and if the window treatment of a suitable material unlined, they have to laundered Conclusion In keeping with the changing trends, personal preferences and building design, some modification might be made in the existing window type and its treatment to pave way for creation of new types to enhance the aesthetic appearance of the building.
