−	Homeowners turn to replacement sash windows when they are considering their options for new windows during a remodeling project for a number of reasons. Sash windows provide efficient venting of a room and, for vertical sash windows, draw in cool air from the bottom opening while allowing warm air at the top of the room to escape. There are also a variety of possibilities to move the sashes within the frame which give the homeowner the opportunity to clean both the inside and outside panes of each side of the window.	+	There are a number of options for a replacement sash window. Three of the most popular are  casement swing-in and swing-out windows, vertical sliding windows (double hung and single hung) and  horizontal sliding windows.
−	=== Placement ===	+	=== Casement Windows ===
−	Sash windows are a suitable replacement window option for many rooms including bedrooms, bathrooms, kitchens, living rooms, family rooms and dining rooms. Special garden sash windows may be installed in an open area such as a conservatory, porch, pool room or garden room. Different types of sash windows may be included as part of a window grouping which is comprised of both picture windows and sash windows. The replacement sash windows in a window grouping may be placed in-between the fixed frames, on the outside of the picture window or above or below picture windows or other sash windows. Sash windows are also a popular window option for loft and attic windows and can serve as egress exit windows for basement bedrooms and other areas which require an emergency exit window.	+	[[Casement-Windows|Casement windows]] are single pane windows which are hinged on one side of the sash and open as either swing-in or swing-out operation by means of a crank or push mechanism. They are available in many sizes and provide maximum ventilation. Casements may require extra care because of the mechanical crank and weight which press on the lower hinge. Screens install either on the inside or the outside of the window, depending on which direction the window opens. Casement windows are available in vinyl, aluminum, fiberglass, wood, wood clad and composite frames. Homeowners may order casement windows with multi-panes for optimal insulation and a Low-E (low-emissivity) coating on the window to block a portion of the sun's radiative rays. Casement windows come in a wide range of sizes and shapes.
−	=== Operation ===	+	Casement windows may be used as [[Egress-Emergency-Exit-Windows|emergency exit windows]] if their size meets the local code.
−	Homeowners must review the size and shape of the window opening when considering the type of sash window that they want to install. Additional considerations involve the window's purpose, the home design -- both interior and exterior design -- and the placement of the window in relation to surrounding windows.	+
−	=== Sizes and Shapes ===	+	==== Awning Windows ====
−	Sash windows are available in a wide range of sizes and shapes including small windows from 18 inches in length or width to nearly four feet in width or length.	+	[[Awning-Windows|Awning windows]] are a type of casement windows which are hinged on the top of the sash, instead of the side. They may open inward or outward and are often installed in bathrooms, basement bedrooms and on top of other windows to increase ventilation.
−	Sash windows come in traditional squares and rectangles as well as in rounds, ovals, hexagons and octagon. Homeowners can find a standard size and shape replacement sash window to fit most openings or, for an additional add-on price, may custom order a window for a hard-to-fit wall opening.	+	==== Hopper Windows ====
		+	[[Hopper-Windows|Hopper windows]] are a type of casement windows which are hinged on the bottom of the sash. They open both inward and outward and are frequently installed under a larger window as a compliment to the window design.
−	=== Considerations ===	+	=== Vertical Sliding Windows ===
−	A major consideration relating to the question of when to purchase a sash window and when to purchase a fixed window may center on the window's price. Sash windows are a more expensive window option because the operating hardware adds to the price. Many homeowners install a fixed window whenever possible to reduce the cost of replacing windows.	+	[[Vertical-Sliding-Windows|Vertical sliding windows]] consist of two panes which can be raised or lowered to provide a ventilation opening.  The internal mechanism of the vertical sliding window permits easy manipulation of the panes. Vertical sliding windows are often installed in bedrooms, kitchens, living rooms, dining rooms, home offices and in lofts and attics. They are manufactured from a variety of framing materials including wood, wood clad, vinyl, composite, aluminum and fiberglass. Glazing options for vertical sliding windows include multi-pane windows and Low-E (low emissivity) coating which reduced solar gain. Screens clip into the outside of vertical sliding window frame and can be easily removed for cleaning. Vertical sliding windows are elongated windows which are installed in long window openings.
−	If the window is needed for ventilation purposes, a sash window is the only option because it offers the needed venting. Replacement windows which are installed in areas in which there is already sufficient ventilation may be replaced with a picture window for cost efficiency.	+	There are two main types of replacement vertical sliding windows, single hung windows and double hung windows.
−	A further consideration regarding sash windows involves the window's thermal resistance. Operating windows, by design, are susceptible to leakage and heat transfer. However, with proper framing materials and glazing, a sash window can offer the same energy efficiency as that which a fixed window can provide.	+	==== Single Hung Windows ====
		+	[[Single-Hung-Windows|Single hung windows]] have two sashes but only the lower sash may be raised or lowered. The top pane is fixed. Single hung windows are sometimes chosen as a less expensive vertical replacement sliding window alternative.
−	==== Framing Materials ====	+	==== Double Hung Windows ====
−	When choosing a replacement window a homeowner will want to select the most durable and energy efficient framing material in order to ensure that the window will provide a cost-efficient window alternative. The window's purchase price is one consideration but as better sash windows become available, homeowners are increasingly aware that a modest savings during the initial purchase of the window can end up costing two, three or four times that amount in added maintenance and energy costs over the lifetime of the window.	+	Replacement [[Double Hung Windows|double hung windows]] feature two sashes, both of which can be raised or lowered. These windows are easier to clean than the single hung windows.
−	Replacement sash windows are rated with a U-Rating, an industry standard which judges the thermal insulating capability of a window. The U-Rating is based on the window's ability to withstand the weather's elements and provide thermal insulation. The U-Rating is determined by the National Fenestration Rating Council which judges the energy performance for windows which are sold worldwide. The U-Rating is accepted by governments and manufacturers throughout the world. The U.S. Department of Energy notes that windows that have a U-Rating of 30 or under can save a homeowner between 7 and 15 percent annually in reduced energy costs.	+	=== Horizontal Sliding Windows ===
		+	[[Horizontal Sliding Windows|Horizontal sliding windows]] often simply referred to as 'Sliding Windows', have two sashes. In some horizontal sliding windows, one of the sashes is fixed while the second moves within the frame. In other horizontal replacement windows, both sashes can move horizontally within the frame. Horizontal sliding windows are one of the least expensive operable window options available on the market today. They are produced with fiberglass, composite, wood, wood clad, aluminum and vinyl frames and may include single, double or triple glazing. It is possible to order horizontal sliding windows with a Low-E coating to lower energy loss.
−	Tax rebates, both on a local and national level, provide financial assistance to homeowners who want to buy well-insulated replacement sash windows. These incentives offer an additional cost reduction over the energy savings. The United States Department of Energy estimates that low U-Rated windows allow homeowners to recoup the added cost of an energy efficient replacement sash window's purchase through saved energy costs within four years of purchase.	+	{{Replacement Window Types}}
−	The framing material is a major factor in a sash window's durability and energy efficiency and is a central aspect of a window's U-Rating. Replacement sash windows which are produced with a quality framing materials have better insulation which will prevent leakage and heat transfer and will keep energy costs low.	+	[[Category:Replacement Windows]]

−	Framing materials for replacement sash windows include vinyl, fiberglass, wood/wood clad, composite and aluminum.	+
−		+
−	==== Vinyl ====	+
−	Vinyl windows are sturdy and durable. They are a relatively inexpensive, energy efficient window alternative. Vinyl windows with heat-welded joints offer superior resistance to temperature stress over mechanically joined frames because the heat-welded joints stiffen the frames.  Vinyl windows are maintenance free though a homeowner may paint the window if he chooses. Vinyl frames do not corrode.	+
−		+
−	==== Fiberglass ====	+
−	Fiberglass window sash framing material offers good value for the expenditure. Fiberglass windows are a more expensive framing material but are known for being strong and durable with no incidences of cracking, warping or corroding due to weather elements. Fiberglass frames do not expand or contract with weather extremes -- actions which can cause stress on the sash's seals and panes. Fiberglass windows do not require maintenance but can be painted if so desired.	+
−		+
−	==== Aluminum ====	+
−	Aluminum replacement sash windows are a popular window choice because they are less expensive than other window options. They are durable and long-lasting. Due to the fact that aluminum conducts cold and heat it has been, in the past, a poor thermal insulator. Modern aluminum replacement sash windows have thermal breaks which separate the interior and exterior surfaces of the sash, improving its energy efficiency. Aluminum frames resist deterioration because the baked-on or anodized finishes protect the frame. Aluminum sash windows compliment a variety of architectural designs.	+
−		+
−	==== Wood/Wood Clad Windows ====	+
−	Many homeowners appreciate the look of wood windows which compliment both traditional and contemporary home designs. While wood frames are an excellent insulator for replacement sash windows they require yearly maintenance, in the form of painting or varnishing, to prevent rot and warping. The need for yearly maintenance can deter potential buyers. An option which offers the attractive look of a wood interior frame together with a weather resistant exterior is aluminum clad sash windows. Aluminum cladding is applied to the window frame's exterior to increase thermal resistance and provide protection for the window from the weather's elements. In addition, the option of aluminum cladding offers an elegant wood interior frame in conjunction with a protective exterior.	+
−		+
−	==== Composite ====	+
−	Composite sash windows are a new window framing option which utilize a composite material created from plastic resins and chemically-bonded blends of wood. One of the most popular composite window materials involves recycled plastic blended with wood chips. Composite replacement sash windows are a new addition to the window market so there is no long-term study of the windows' durability but increasing numbers of homeowners report positive experiences with the composite frames which do not corrode, deteriorate or require maintenance.	+
−		+
−	=== Glazing ===	+
−	The glazing options for a replacement sash window will compliment the framing material and produce a window with good thermal insulation. Proper glazing of a replacement sash window creates an energy-efficient window which blocks heat transfer and other weather elements.	+
−		+
−	Glazing options also include different textures, colors, cleaning options and window strengths.	+
−		+
−	==== Strengthened Glass ====	+
−	Glass for replacement sash windows is available as laminated or tempered glazing. These safety glass alternatives can prevent burglaries while offering an additional safety measure which to protect young children from being hurt if they crash into a window. Safety glass options are dependent on the window's location.	+
−		+
−	==== Self-Cleaning Glass ====	+
−	Homeowners who position a replacement sash window in a hard-to-reach area may wish to order a self-cleaning window. A self-cleaning window allows water and cleaning materials to roll off the window, automatically cleaning it. Replacement sash windows which are installed in lofts and gables can benefit from a self-cleaning option.	+
−		+
−	==== Glass Colors and Patterns ====	+
−	Replacement sash windows may be ordered with clouded or tinted glass including patterned glass or bronze, blue or brown glass panels. A homeowner may want to consider such privacy glass for a basement bedroom window or a bathroom window. Patterned or textured glass is available in a wide range of designs.	+
−		+
−		+
−	==== Multi-Panes ====	+
−	Multi-pane replacement sash windows are available with double or triple panes of glass. The air between the glass panes acts as an insulator. Specific window manufacturers offer the option to insulate the gap between the panes with an insulating gas such as argon or krypton gas. Multi-pane windows increase resistance to heat transfer and enhance the level of thermal insulation of the replacement sash window. Industry observers suggest that homeowners who are renovating in an extreme climate consider a triple-pane window.	+
−		+
−		+
−	==== Low E ====	+
−	The Low-E (low-emissivity) coating is applied to a replacement sash window while the window is still in the factory. It is offered by many window manufacturers who recommend the option for sun-facing windows. Low-E is an invisible microscopically thin metallic coating which suppresses the sun's radiative heat flow, thus reducing the window's U-Rating. As it blocks a portion of radiant heat transfer it lowers the total heat flow that enters a room. The Low-E coating can also help protect furnishings in a sun-facing room from experiencing fading due to the sun's rays. Homeowners can choose the level of Low-E coating for their windows which meets their home's needs, depending on the climate in which they live. Low-E coating options include Low-E coating for a low solar gain, Low-E for a moderate solar gain or Low-E for a high solar gain.	+

−	Available accessories for replacement sash windows include screens, grilles and hardware.	+
−		+
−	==== Screens ====	+
−	All operating replacement sash windows include screens as part of the window order. The placement of the screen depends on the operation of the window. Single-hung and double-hung sash windows, sliding windows and inward swinging casement windows -- including inward swinging awning and hopper windows -- require screens which clip onto the outside of the window frame. Outward swinging casement windows have screens which clip onto the inside of the window frame.	+

Sash Window

Other Names
Replacement Sash Windows, Moving Pane Windows
Description:
Window built with moveable panels, called "sashes" which form a frame that holds a glass pane

A sash window is a window frame which holds panes of glass. These panes move within the frame, vertically, horizontally, inwards or outwards. Replacement sash windows generally refer to casement windows (including awning and hopper windows), horizontal sliding windows or vertical sliding windows. Replacement sash windows may be installed as single units, be placed side-by-side next to other sash window units or be installed as part of a group of windows that includes different types of windows. Sash windows provide a maximum face opening which allows for ventilation of anywhere from one-half of the total window area to the entire window area. Depending on the window's operation, sash windows may include springs, counterweights and weather-stripping to hold them in place.

[edit] Advantages

Homeowners turn to replacement sash windows when they are considering their options for new windows during a remodeling project for a number of reasons. Sash windows provide efficient venting of a room. In the case of double hung vertical sash windows they can draw in cool air from the bottom opening while allowing warm air at the top of the room to escape. There are also a variety of possibilities to move the sashes within the frame which give the homeowner the opportunity to clean both the inside and outside panes of each side of the window.

[edit] Options

There are a number of options for a replacement sash window. Three of the most popular are casement swing-in and swing-out windows, vertical sliding windows (double hung and single hung) and horizontal sliding windows.

[edit] Casement Windows

Casement windows are single pane windows which are hinged on one side of the sash and open as either swing-in or swing-out operation by means of a crank or push mechanism. They are available in many sizes and provide maximum ventilation. Casements may require extra care because of the mechanical crank and weight which press on the lower hinge. Screens install either on the inside or the outside of the window, depending on which direction the window opens. Casement windows are available in vinyl, aluminum, fiberglass, wood, wood clad and composite frames. Homeowners may order casement windows with multi-panes for optimal insulation and a Low-E (low-emissivity) coating on the window to block a portion of the sun's radiative rays. Casement windows come in a wide range of sizes and shapes.

Casement windows may be used as emergency exit windows if their size meets the local code.

[edit] Awning Windows

Awning windows are a type of casement windows which are hinged on the top of the sash, instead of the side. They may open inward or outward and are often installed in bathrooms, basement bedrooms and on top of other windows to increase ventilation.

[edit] Hopper Windows

Hopper windows are a type of casement windows which are hinged on the bottom of the sash. They open both inward and outward and are frequently installed under a larger window as a compliment to the window design.

[edit] Vertical Sliding Windows

Vertical sliding windows consist of two panes which can be raised or lowered to provide a ventilation opening. The internal mechanism of the vertical sliding window permits easy manipulation of the panes. Vertical sliding windows are often installed in bedrooms, kitchens, living rooms, dining rooms, home offices and in lofts and attics. They are manufactured from a variety of framing materials including wood, wood clad, vinyl, composite, aluminum and fiberglass. Glazing options for vertical sliding windows include multi-pane windows and Low-E (low emissivity) coating which reduced solar gain. Screens clip into the outside of vertical sliding window frame and can be easily removed for cleaning. Vertical sliding windows are elongated windows which are installed in long window openings.

There are two main types of replacement vertical sliding windows, single hung windows and double hung windows.

[edit] Single Hung Windows

Single hung windows have two sashes but only the lower sash may be raised or lowered. The top pane is fixed. Single hung windows are sometimes chosen as a less expensive vertical replacement sliding window alternative.

[edit] Double Hung Windows

Replacement double hung windows feature two sashes, both of which can be raised or lowered. These windows are easier to clean than the single hung windows.

[edit] Horizontal Sliding Windows

Horizontal sliding windows often simply referred to as 'Sliding Windows', have two sashes. In some horizontal sliding windows, one of the sashes is fixed while the second moves within the frame. In other horizontal replacement windows, both sashes can move horizontally within the frame. Horizontal sliding windows are one of the least expensive operable window options available on the market today. They are produced with fiberglass, composite, wood, wood clad, aluminum and vinyl frames and may include single, double or triple glazing. It is possible to order horizontal sliding windows with a Low-E coating to lower energy loss.
