Many homeowners here in Campbellsville are looking to replace their worn-out windows with new windows that operate and perform better, are more durable, require considerably less maintenance and are more energy efficient than the wood, steel or aluminum windows that were used when their homes were built.
Most people look at new windows as an expense, they’re not. New windows are an investment in your home. An investment which, if made wisely, not only increases the value of your Campbellsville home, but at the same time, cuts your energy bills, increases your comfort and reduces maintenance cost. However, like any investment decision, you need to determine what gives you the greatest value, not necessarily the lowest price.
You need to educate yourself so you really understand what you are getting for your money. This is why it is important for a homeowner to work with someone they trust who walks them through the various options so they can make an educated buying decision.In most cases, style is already determined by the architecture of the house and the type of windows that are presently there. However, it is possible to change window styles, change opening sizes, add bays and bows, or do a variety of other things that will dramatically change the appearance of your home inside and out.
Since it represents the largest area of the window, glass obviously has the biggest impact on energy loss. Glass technology has made tremendous strides over the last few years. Things like low conductivity spacers, low emissivity, or Low-E, coatings and gas filling have drastically cut the amount of energy that flows through the glass.Low-E is an almost invisible metallic coating that works like a one-way mirror, reflecting heat back into your home during the winter and reflecting it out during the summer.
There are different types of Low-E coatings with different performance levels. Better performing coatings, like Titanium, cost a little more, but are well worth the money. Don’t settle for products made with regular clear glass that is not coated.Warranties are also very important. Be sure you understand them fully. Just because it says Lifetime don’t assume every component of the window and installation is covered forever. And remember, the warranty is only as good as the people who back it.
Replacement Windows – A Buyers Guide For Campbellsville Homeowners
If a double pane window is better than a single pane window, should I use triple pane windows?This is getting to be an appropriate question, "Should a window retrofit use triple pane windows?" The vinyl window manufactures are getting so good at making energy-efficient windows, it doesn't take much for them to throw in another pane of glass or two. Wonder if we will be considering quad pane windows one of these days?If you were really interested in saving energy and wanted the best wall construction possible, you wouldn't put a window in the wall to begin with. A wall without a window has a greater R-value and fewer air leaks. We know how to build a wall that will separate the outdoors from the indoors - what we don't know how to do is build a wall that will keep the outdoors out and the indoors in and still let light through. Come to think about it, our need to let light in is at the root of the problem.Actually, letting light in is just one of the needed benefits of having a wall with a window. Being able to see through the wall is another benefit and being able to get out of a room during a fire is another. Energy wise, a door is not much better than a window, so I guess windows are here to stay.The Space Between the Glass:A window with more than one piece of glass is a real blessing for saving energy and helping with indoor comfort. There is more to a vinyl window than just several panes of glass. Two panes of glass also come with an insulated frame, mounting flange, and better air seals. But the most important part is not the glass, but the space between the glass. Considering window performance, it's the space between the glass that makes the difference.The Future of Windows:In the near future, the efficiency ratings of windows will continue to drop. The only way a window manufacturer will be able to reach the energy efficiency ratings of the future is with three or four panes of glass. If you are seriously considering a retrofit window project, you should select the best window for your climate and that means the window will have three panes of glass.Yes, three pane windows are more expensive than two pane windows. Shop around for the best U-factor and the best SHGC for the best price. If finances are the deciding factor, it will be better to install two triple pane windows than three double pane windows. Stick with the triple pane window and you will have greater energy efficiency for the future which will save you money for years to come.P.S. Buy your windows and window installation from a local glass company or a licensed general contractor. Please don't buy our windows from a super salesman at a home show that has all the financing you need and a worthless lifetime warranty to go with it.Thanks for stopping by, please come back soon, but I won't leave the light on for you...
Opting For Triple Glazing For Your Window SolutionWindow of traditional design in Porto Covo, Portugal Cylindrical lattice window of Sumburgh Head Lighthouse (Shetland).
A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and/or air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.
Types include the eyebrow window, fixed windows, single-hung and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, emergency exit windows, stained glass windows, French windows, panel windows, and double - and triple paned windows.
The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt, in Alexandria ca. 100 AD. Paper windows were economical and widely used in ancient China, Korea and Japan. In England, glass became common in the windows of ordinary homes only in the early 17th century whereas windows made up of panes of flattened animal horn were used as early as the 14th century. In the 19th century American west, greased paper windows came to be used by itinerant groups. Modern-style floor-to-ceiling windows became possible only after the industrial plate glass making processes were perfected.
The English language-word window originates from the Old Norse 'vindauga', from 'vindr – wind' and 'auga – eye', i.e., wind eye. In Norwegian Nynorsk and Icelandic the Old Norse form has survived to this day (in Icelandic only as a less used synonym to gluggi), in Swedish the word vindöga remains as a term for a hole through the roof of a hut, and in the Danish language 'vindue' and Norwegian Bokmål 'vindu', the direct link to 'eye' is lost, just like for 'window'. The Danish (but not the Bokmål) word is pronounced fairly similarly to window.
Window is first recorded in the early 13th century, and originally referred to an unglazed hole in a roof. Window replaced the Old English eagþyrl, which literally means 'eye-hole,' and 'eagduru' 'eye-door'. Many Germanic languages however adopted the Latin word 'fenestra' to describe a window with glass, such as standard Swedish 'fönster', or German 'Fenster'. The use of window in English is probably because of the Scandinavian influence on the English language by means of loanwords during the Viking Age. In English the word fenester was used as a parallel until the mid-18th century. Fenestration is still used to describe the arrangement of windows within a façade, as well as defenestration, meaning to throw something out of a window.Fragment of a Roman window glass plate dated to 1st to 4th century A.D.
Note the obvious curvature, this is not a flat pane. Alabaster 'mullion' divided decorative windows in Santa Maria La Major church (Morella, Spain). Alabaster window in the Valencia Cathedral. Note the asymmetrical, slanted left side of the wall-frame, which lets sun rays reach the chancel.
In the 13th century BC, the earliest windows were unglazed openings in a roof to admit light during the day. Later, windows were covered with animal hide, cloth, or wood. Shutters that could be opened and closed came next.[when?] Over time, windows were built that both protected the inhabitants from the elements and transmitted light, using multiple small pieces of translucent material (such as flattened pieces of translucent animal horn, thin slices of marble, or pieces of glass) set in frameworks of wood, iron or lead. In the Far East, paper was used to fill windows. The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt. Namely, in Alexandria ca. 100 AD cast glass windows, albeit with poor optical properties, began to appear, but these were small thick productions, little more than blown glass jars (cylindrical shapes) flattened out into sheets with circular striation patterns throughout. It would be over a millennium before a window glass became transparent enough to see through clearly, as we think of it now.
Over the centuries techniques were developed to shear through one side of a blown glass cylinder and produce thinner rectangular window panes from the same amount of glass material. This gave rise to tall narrow windows, usually separated by a vertical support called a mullion. Mullioned glass windows were the windows of choice among European well-to-do, whereas paper windows were economical and widely used in ancient China, Korea and Japan. In England, glass became common in the windows of ordinary homes only in the early 17th century whereas windows made up of panes of flattened animal horn were used as early as the 14th century.
Modern-style floor-to-ceiling windows became possible only after the industrial plate glass making processes were perfected. Modern windows are usually filled with glass, although a few are transparent plastic.
The term eyebrow window is used in two ways: a curved top window in a wall or in an eyebrow dormer; and a row of small windows usually under the front eaves such as the James-Lorah House in Pennsylvania.
A fixed window is a window that cannot be opened, whose function is limited to allowing light to enter (unlike an unfixed window, which can open and close). Clerestory windows in church architecture are often fixed. Transom windows may be fixed or operable. This type of window is used in situations where light or vision alone is needed as no ventilation is possible windows without the use of trickle vents or overglass vents.
A single-hung sash window is a window that has one sash that is movable (usually the bottom one) and the other fixed. This is the earlier form of sliding sash window, and is also cheaper.
A sash window is the traditional style of window in the United Kingdom, and many other places that were formerly colonized by the UK, with two parts (sashes) that overlap slightly and slide up and down inside the frame. The two parts are not necessarily the same size; where the upper sash is smaller (shorter) it is termed a cottage window. Currently most new double-hung sash windows use spring balances to support the sashes, but traditionally, counterweights held in boxes on either side of the window were used. These were and are attached to the sashes using pulleys of either braided cord or, later, purpose-made chain. Three types of spring balances are called a tape or clock spring balance; channel or block-and-tackle balance; and a spiral or tube balance.
Double-hung sash windows were traditionally often fitted with shutters. Sash windows can be fitted with simplex hinges that let the window be locked into hinges on one side, while the rope on the other side is detached—so the window can be opened for fire escape or cleaning.
A horizontal sliding sash window has two or more sashes that overlap slightly but slide horizontally within the frame. In the UK, these are sometimes called Yorkshire sash windows, presumably because of their traditional use in that county.Main article: Casement window Casement window
A casement window is a window with a hinged sash that swings in or out like a door comprising either a side-hung, top-hung (also called "awning window"; see below), or occasionally bottom-hung sash or a combination of these types, sometimes with fixed panels on one or more sides of the sash. In the USA, these are usually opened using a crank, but in parts of Europe they tend to use projection friction stays and espagnolette locking. Formerly, plain hinges were used with a casement stay. Handing applies to casement windows to determine direction of swing; a casement window may be left-handed, right-handed, or double. The casement window is the dominant type now found in modern buildings in the UK and many other parts of Europe.Awning window
An awning window is a casement window that is hung horizontally, hinged on top, so that it swings outward like an awning. In addition to be used independently, they can be stacked, several in one opening, or combined with fixed glass. They are particularly useful for ventilation.
A hopper window is a bottom-pivoting casement window that opens by tilting vertically, typically to the inside. (Mostly used for schools)
A pivot window is a window hung on one hinge on each of two opposite sides which allows the window to revolve when opened. The hinges may be mounted top and bottom (Vertically Pivoted) or at each jamb (Horizontally Pivoted). The window will usually open initially to a restricted position for ventilation and, once released, fully reverse and lock again for safe cleaning from inside. Modern pivot hinges incorporate a friction device to hold the window open against its own weight and may have restriction and reversed locking built in. In the UK, where this type of window is most common, they were extensively installed in high-rise social housing.
A tilt and slide window is window (more usually a door-sized window) where the sash tilts inwards at the top and then slides horizontally behind the fixed pane.
A tilt and turn window can both tilt inwards at the top or open inwards from hinges at the side. This is the most common type of window in Germany, its country of origin. It is also widespread in many other European countries. In Europe it is usual for these to be of the "turn first" type. i.e. when the handle is turned to 90 degrees the window opens in the side hung mode. With the handle turned to 180 degrees the window opens in bottom hung mode. Most usually in the UK the windows will be "tilt first" i.e. bottom hung at 90 degrees for ventilation and side hung at 180 degrees for cleaning the outer face of the glass from inside the building.
A window above a door; in an exterior door the transom window is often fixed, in an interior door it can open either by hinges at top or bottom, or rotate on hinges. It provided ventilation before forced air heating and cooling. A fan-shaped transom is known as a fanlight, especially in the British Isles.
Windows beside a door or window are called side-, wing-, and margen-lights and flanking windows.Jalousie or louvered window
Also known as a louvered window, the jalousie window consists of parallel slats of glass or acrylic that open and close like a Venetian blind, usually using a crank or a lever. They are used extensively in tropical architecture. A jalousie door is a door with a jalousie window.Clerestory window Main article: Clerestory
A clerestory window is a window set in a roof structure or high in a wall, used for daylighting.Main article: Daylighting Sidewalk skylight (also named 'pavement light') made of Glass brick in Burlington House, London
A skylight is a window built into a roof structure. This type of window allows for natural daylight and moonlight.Hexagonal external cladding panels of roof in Eden Project Biomes (Cornwall, England,)
A sloped window used for daylighting, built into a roof structure. It is one of the few windows that could be used as an exit. Larger roof windows meet building codes for emergency evacuation.Main article: Cupola
A roof lantern is a multi-paned glass structure, resembling a small building, built on a roof for day or moon light. Sometimes includes an additional clerestory. May also be called a cupola.Main article: Bay window
A bay window is a multi-panel window, with at least three panels set at different angles to create a protrusion from the wall line.Main article: Oriel window
This form of bay window most often appears in Tudor-style houses and monasteries. It projects from the wall and does not extend to the ground. Originally a form of porch, they are often supported by brackets or corbels.Main article: Diocletian window
Thermal, or Diocletian, windows are large semicircular windows (or niches) which are usually divided into three lights (window compartments) by two mullions. The central compartment is often wider than the two side lights on either side of it.
A picture window is a large fixed window in a wall, typically without glazing bars, or glazed with only perfunctory glazing bars near the edge of the window. Picture windows provide an unimpeded view, as if framing a picture.
A multi-lite window is a window glazed with small panes of glass separated by wooden or lead glazing bars, or muntins, arranged in a decorative glazing pattern often dictated by the building's architectural style. Due to the historic unavailability of large panes of glass, the multi-lit (or lattice window) was the most common window style until the beginning of the 20th century, and is still used in traditional architecture.
An emergency exit window is a window big enough and low enough so that occupants can escape through the opening in an emergency, such as a fire. In many countries, exact specifications for emergency windows in bedrooms are given in many building codes. Specifications for such windows may also allow for the entrance of emergency rescuers. Vehicles, such as buses and aircraft, frequently have emergency exit windows as well.Visual effect Sunlight shining through stained glass Main article: stained glass
A Stained glass window is a window composed of pieces of colored glass, transparent, translucent or opaque, frequently portraying persons or scenes. Typically the glass in these windows is separated by lead glazing bars. Stained glass windows were popular in Victorian houses and some Wrightian houses, and are especially common in churches.A "French Window" (two French doors on an exterior wall hinged to open outward together without a mullion separating them) at the Embassy of France in Lisbon, early twentieth century.
A French door  has two rows of upright rectangular glass panes (lights) extending its full length and two of these doors on an exterior wall and without a mullion separating them, that open outward with opposing hinges to a terrace or porch, are referred to as a French Window. Sometimes these are set in pairs or multiples thereof along the exterior wall of a very large room, but often, one French window is placed centrally in a typically-sized room, perhaps among other fixed windows flanking the feature. French windows are known as porte-fenêtre in France and portafinestra in Italy, and frequently are used in modern houses.Main article: Insulated glazing
Double-paned windows have two parallel panes (slabs of glass) with a separation of typically about 1 cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry nonreactive gas. Such windows provide a marked improvement in thermal insulation (and usually in acoustic insulation as well) and are resistant to fogging and frosting caused by temperature differential. They are widely used for residential and commercial construction in intemperate climates. Triple-paned windows have been commercially manufactured and marketed with claims of additional benefit but have not become common. In the UK double-paned and triple-paned are referred to as double-glazing and triple-glazing.Main article: hexagonal window
A hexagonal window is a hexagon-shaped window, resembling a bee cell or crystal lattice of graphite. The window can be vertically or horizontally oriented, openable or dead. It can also be regular or elongately-shaped and can have a separator (mullion). Typically, the cellular window is used for an attic or as a decorative feature, but it can also be a major architectural element to provide the natural lighting inside buildings.
EN 12519 is the European norm that describes windows terms officially used in EU Member States. The main terms are:Casement window, with latticed lights In the UK and mainland Europe, windows in new-build houses are usually fixed with long screws into expanding plastic plugs in the brickwork. A gap of up to 13 mm is left around all four sides, and filled with expanding polyurethane foam. This makes the window fixing weatherproof but allows for expansion due to heat.
The United States NFRC Window Label lists the following terms:
The European harmonised standard hEN 14351-1, which deals with doors and windows, defines 23 characteristics (divided into essential and non essential. Two other, preliminary European Norms that are under development deal with internal pedestrian doors (prEN 14351-2), smoke and fire resisting doors, and openable windows (prEN 16034).5-chamber plastic window profile Examples of modern plastic and wooden window profiles with insulated glazing Modern wooden framed window fitted in the 14th century Lyme Regis watermill, UK.
Windows can be a significant source of heat transfer. Therefore, insulated glazing units consist of two or more panes to reduce the transfer of heat.
These are the pieces of framing that separate a larger window into smaller panes. In older windows, large panes of glass were quite expensive, so muntins let smaller panes fill a larger space. In modern windows, light-colored muntins still provide a useful function by reflecting some of the light going through the window, making the window itself a source of diffuse light (instead of just the surfaces and objects illuminated within the room). By increasing the indirect illumination of surfaces near the window, muntins tend to brighten the area immediately around a window and reduce the contrast of shadows within the room.
Frames and sashes can be made of the following materials:*PVC and fiberglass frames perform well in accelerated weathering tests. Because PVC is not as strong as other materials, some PVC frames are reinforced with metal or composite materials to improve their structural strength. **Modern aluminium window frames are typically separated by a thermal break made of a glass fibre reinforced polyamide. With a 34 mm thermal insulation profile it is possible to reach Uf= 1.3 W/m²K for a metal window. This greatly increases thermal resistance, while retaining virtually all of the structural strength.
Composites (also known as Hybrid Windows) are start since early 1998 and combine materials like aluminium + pvc or wood to obtain aesthetics of one material with the functional benefits of another.A typical installation of insulated glazing windows with uPVC window frames.
A special class of PVC window frames, uPVC window frames, became widespread since the late 20th century, particularly in Europe: there were 83.5 million installed by 1998 with numbers still growing as of 2012.
Low-emissivity coated panes reduce heat transfer by radiation, which, depending on which surface is coated, helps prevent heat loss (in cold climates) or heat gains (in warm climates).
High thermal resistance can be obtained by evacuating or filling the insulated glazing units with gases such as argon or krypton, which reduces conductive heat transfer due to their low thermal conductivity. Performance of such units depends on good window seals and meticulous frame construction to prevent entry of air and loss of efficiency.
Modern double-pane and triple-pane windows often include one or more low-e coatings to reduce the window's U-factor (its insulation value, specifically its rate of heat loss). In general, soft-coat low-e coatings tend to result in a lower solar heat gain coefficient (SHGC) than hard-coat low-e coatings.
Modern windows are usually glazed with one large sheet of glass per sash, while windows in the past were glazed with multiple panes separated by glazing bars, or muntins, due to the unavailability of large sheets of glass. Today, glazing bars tend to be decorative, separating windows into small panes of glass even though larger panes of glass are available, generally in a pattern dictated by the architectural style at use. Glazing bars are typically wooden, but occasionally lead glazing bars soldered in place are used for more intricate glazing patterns.
Many windows have movable window coverings such as blinds or curtains to keep out light, provide additional insulation, or ensure privacy. Windows allow natural light to enter, but too much can have negative effects such as glare and heat gain. Additionally, while windows let the user see outside, there must be a way to maintain privacy on in the inside. Window coverings are practical accommodations for these issues.Main article: Daylighting
Historically, windows are designed with surfaces parallel to vertical building walls. Such a design allows considerable solar light and heat penetration due to the most commonly occurring incidence of sun angles. In passive solar building design, an extended eave is typically used to control the amount of solar light and heat entering the window(s).
An alternative method is to calculate an optimum window mounting angle that accounts for summer sun load minimization, with consideration of actual latitude of the building. This process has been implemented, for example, in the Dakin Building in Brisbane, California—in which most of the fenestration is designed to reflect summer heat load and help prevent summer interior over-illumination and glare, by canting windows to nearly a 45 degree angle.Main article: Photovoltaics
Photovoltaic windows not only provide a clear view and illuminate rooms, but also convert sunlight to electricity for the building. In most cases, translucent photovoltaic cells are used.
Passive solar windows allow light and solar energy into a building while minimizing air leakage and heat loss. Properly positioning these windows in relation to sun, wind, and landscape—while properly shading them to limit excess heat gain in summer and shoulder seasons, and providing thermal mass to absorb energy during the day and release it when temperatures cool at night—increases comfort and energy efficiency. Properly designed in climates with adequate solar gain, these can even be a building's primary heating system.
A window covering is a shade or screen that provides multiple functions. Some coverings, such as drapes and blinds provide occupants with privacy. Some window coverings control solar heat gain and glare. There are external shading devices and internal shading devices. Low-e window film is a low-cost alternative to window replacement to transform existing poorly-insulating windows into energy-efficient windows. For high-rise buildings, smart glass can provide an alternative.
