Window TreatmentsInterior & Exterior Components • Exterior: • Awnings: weather resistant fabrics, metal: either material can be used to make adjustable/roll up components: awnings can reduce solar heat gain through fenestration by as much as 75%. • Shutters: temper light, heat, and cold: secure windows against physical damage: actual operable shutters are common in many parts of the world, but artifical shutters are typical in the US. • Cutouts and Projecting Elements: overhanging roofs, trellises, an exterior vertical element placed to shield the window/view from the interior.
Overhangs: for sun and rain protection,may be used at doors or windows
Pre-fabricated metal grilles:used for balustrades, fences, gates, room partitions
Exterior Window Treatments(continued) • Grilles and Fences: masonry, wood, plastic, or metal grilles and fences: placed close to windows or some feet away: can control privacy, sun, and wind to any degree desired. • Louvers: ventilating panels of wood, metal, or plastic can be effective as sunshades and for weather protection. normally used over windows, they can substitute for glass completely in warm climates
Exterior shutters that are hinged, and actually open and close.

Interior Window Treatments • Hard Treatments: • Shades: • Roller shades pull up and down, and are mounted on rollers. may be mounted at either the top, or the bottom of the window. these reduce light and give privacy in direct relationship to their thickness and translucency or opaqueness. • Roman shades: are attached to tapes that pleat the fabric when drawn by using cords. Roman shades pleat in definite horizontal lines as they are raised. • they may unfold flat or in cascading loops.
Bamboo or matchstick, and woven-wood shades: • these function much like those made of fabric, either rolling or folding as they are raised. they differ in that they usually let more light through, and give a better view of the outside. • Pleated: shades made of a polyester web or mesh material: they filter or block sunlight while remaining visually unobtrusive. • Honeycomb pleated shades are paired, two layers, creating an insulating air pocket between the two layers of fabric.
Thermal Shades: constructed of multiple layers of insulating fabric, often surrounding a reflective Mylar sheet, are used to control heat loss or gain. they can either roll, or pleat, but require more space at the top of the window when opened because of their high bulk. • Thermal shades can reduce heat loss/gain by up to 80%. • The drawbacks of shades include the fact that when pulled down they cut out the light from the top of the window first. shades can also block a breeze, or whip around in the wind.

Blinds: • Horizontal: venetian, mini, micro: these are horizontal oriented slats of wood, metal, or plastic. venetian blinds are typically 2” slats: mini blinds are typically 1” slats, and micro blinds are typically 1/2” slats. • All of these horizontally oriented blinds collect dust and dirt, and are somewhat difficult to clean. • Vertical : blinds of metal, wood, vinyl, or fabric. vertical blinds collect much less dust and dirt than horizontal blinds.
Grilles, Screens, Panels: used when windows are unatractive, or when views are not desired. screens may fold back, slide on a track, or remain stationary. screens filled with translucent material are called ‘shoji’ by the Japanese. • stained glass, beveled, or leaded glass, wood, or vinyl lattice panels are all used as materials to construct interior window panels.
Shutters: fixed or moveable panels or wood slats or louvers on a framework, hinged to the window frame. most louvers are 1” wide, but plantation shutters are a louver that is typically 2” wide. shutters are generally more initially expensive than fabric window treatments but across the life span of the sutter the initial cost is more than repaid. • Bare windows: when windows are well designed, and the relationship to the outside is carefully considered, additional window treatments may be unnecessary. even so, a bare window becomes a black reflective surface at night, and it permits an unobstructed view into the interior environment.
Soft Window Treatments: • in addition to flexibly controlling privacy, light, , and heat, curtains and draperies soak up noise in proportion to the area they cover, the thickness of the fabric, and the depth of the folds. • Curtains: usually of lightweight, unlined fabric that filters and diffuses light. curtains are used either alone, or under drapery, hung next to the glass. • Sheers: thin, often sheer or semisheer fabrics, hung closest to the glass.
Sash curtains: a type of curtain hung on the window sash. they can be stretched taut between rods at the top and the bottom of the window sashes, or hung in loose folds. they are often used on doors that contain windows. • Draw curtains: usually of translucent or lightweight opaque fabrics, are mounted on traverse rods that provide a pulley mechanism that allows the curtain to be drawn, or pulled, open or closed. • Casement curtains: open weave fabric usually more opaque than a sheer. may be used alone or under drapery and may also be mounted on traverse rods.
Draperies: are any loosely hung (not stretched) fabric. (this term really includes all curtains) generally, draperies are thought of as heavy, opaque fabrics that can be drawn or that stand idly at the sides of windows purely for decoration. draperies should be lined if not used with sheers. • Cornices: rigid horizontal bands several inches dep placed at the window top to conceal curtain tops and the rods from which they hang. constructed of wood, they are somwhat architectural in feeling and relate window treatment to walls and ceiling. upholstered cornices are padded and covered with fabric.
Valences: made of fabric draped across or covering a rod or shaped form at the tops of the windows. they are more closely allied with the drapery than with the wall, and are decorative in nature. valences are open at the top. • Portieres: these are currtains or draperies hung in open doorways or arches between interior spaces, often tied back or let down for privacy or insulation.
Measuring and Estimating • Rough estimate of fabric needed: • measure the width of the window, including any wall space to be covered. multiply this figure by 2, or by 3, to provide adequate fullness (the lighter weight the fabric, the fuller it should be) • divide the width of the fabric that is to be used and round the answer to the next larger whole number. (common widths for drapery fabric are 45 and 50 inches” • the result is the number of panels of fabric needed. • Next: measure the height of the window in inches, including the wall space above, and below that will be covered. add 16 to 18 inches to allow for generous hems (a double 4” heading at the top, and a double 4” hem at the bottom). • the yardage required for the window is the product of the number of panels needed multiplied by the total length needed.
