 Framing Materials
When choosing a replacement horizontal sliding 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 horizontal sliding 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 horizontal sliding window 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.
Tax rebates, both on a local and national level, provide financial assistance to homeowners who want to buy well-insulated replacement horizontal sliding 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.
The framing material is a major factor in a replacement horizontal sliding window's durability and energy efficiency and is a central aspect of a window's U-Rating. Replacement horizontal sliding 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.
Framing materials for replacement horizontal sliding windows include vinyl, fiberglass, wood/wood clad, composite and aluminum.
Vinyl windows are a sturdy and durable replacement horizontal sliding window alternative. 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 replacement horizontal sliding window 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 replacement horizontal sliding 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 horizontal sliding 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 replacement horizontal sliding 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 horizontal sliding windows they require yearly maintenance, in the form of painting or varnishing, to prevent rot and warping. The need for annual 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 horizontal sliding 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 sash windows are a new window framing option in which the frame utilizes a composite material created from plastic resins and chemically-bonded blends of wood.

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 horizontal sliding 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 a replacement horizontal sliding window which meets their home's needs, depending on the climate in which they live.
