A bay window consists of three window segments that project out from the wall to the outside at a sharp angle, most often either 30, 45, or 90 degrees. A bay window can consist of a number of different configurations.
The most common is a quarter-half-quarter layout with a picture window as the center window and either casement or double-hung windows as the end windows. We call these end windows “flankers”. Bay windows typically have a wider sill, called a seatboard, which can be a wonderful little nook for any number of décor ideas.
A bow window is similar to a bay window in that it also projects out from the wall to the outside. However, a bow window curves instead of being at an angle. A bow window can consist of several different configurations. Bow windows are divided into even sections, called lites.
The most common types are 3-lite, 4-lite, and 5-lite bow windows. The operating lites are typically casement or double-hung windows and the fixed lites are either picture windows or fixed casement windows. The end windows, or flankers, typically operate, or all the windows can be fixed picture windows. A bow window also has a window sill, like a bay window.
A casement window is most commonly recognized as a crank-out window. These windows are often seen as part of a bay or bow window, but these are not the only places where casement windows are an appealing option.
Above a kitchen sink or in a space where you are really looking to maximize the opening area of the window are great places for casement windows. Casement windows can be one single window or multiple lite, depending on the opening and application.
Sliding windows do just that, slide. Sliding windows have many great applications, but are probably most commonly recognized as part of a sunroom or porch enclosure. These windows allow you to open either the left or right side of the window. Most commonly seen in the 2-lite option, these windows can also be 3 lites, with the end lites operating and a fixed lite in the middle.
Double-hung windows are probably the most common style of window. These windows consist of a top lite (or sash) and a bottom lite (or sash). Double-hung windows can typically be opened from the top or the bottom. This is a versatile window style that can be used not only in your home, but also works well for additions, sunrooms, and porch enclosures.
U Factor: U Factor measures thermal insulation. The U Factor indicates how easily heat will flow through the window, whereas the R Factor indicates the opposite, how well the window will resist heat flow. The lower the U Factor, the better a window insulates.
Solar Heat Gain Coefficient (SHGC): SHGC measures the amount of solar radiation admitted through a window. The lower a window’s SHGC, the less solar heat is transmitted into the house and the easier it is to keep your house cool in summer.
On the other hand, in northern climates, a higher SHGC can provide beneficial passive solar heating in the winter. Aspect offers a variety of high-performance Low-E glass packages with varying SHGC ratings to suit your needs, based on your needs.
Visible Transmittance (VT): VT measures the percentage of visible light that is admitted through the window. High-performance glass packages have been designed to enhance a window’s thermal performance by blocking ultraviolet and infrared light while maximizing visible light transmission. Clear glass itself blocks about 20% of visible light.
All of ProVia’s windows are tested to standards set forth by the American Architectural Manufacturer’s Association (AAMA) for structural performance. Air infiltration, water penetration, and structural wind loads are three commonly referenced tests.
What Is Air Infiltration? The amount of air that passes through the seals of a window’s operating sashes per minute, per square foot of window. Using a typical vinyl window would be like having a hole in the wall of your home, leaking 9.68 balloons worth of air per minute!
High-quality, energy-efficient windows have air infiltration ratings lower than 0.3. ProVia’s Aspect Series windows achieve an excellent air infiltration rating of 0.05 or below.
Super Spacer® Aspect Windows: ProVia uses advanced Super Spacer® technology as a standard to create insulated glass with a warm edge around the perimeter. The edge of the glass is typically the coldest spot on the window and can be prone to condensation.
Other windows use glass panes with rectangular aluminum that conducts the heat away from the inner pane of glass, which results in a cold edge. Super Spacer® is a non-metallic, structural foam spacer.
Super Spacer® blocks heat escape, dramatically reduces condensation, and offsets the effects of temperature changes that prevent stress cracks.
INNERGY® Thermal Reinforcements: In addition to Super Spacer®, ProVia also uses INNERGY® thermal reinforcements in their windows instead of aluminum. This is an innovative and energy-efficient alternative that is 700 times better than aluminum in material comparisons on thermal performance.

After another disaster trying to use a York county contractor – this time for some simple landscaping because I supposedly have hypertension – I want to thank you again for making the effort to come and fix the window on the sunroom. In brief, they tore out my garden lights along the pathway for some unknown reason (I made him buy me new solar ones), mowed down a bunch of my wife's flowers(I could've done that), and damaged the asphalt drain lip on my driveway backing a trailer in – especially after I told the guy to be careful. He promised to fix it but after two weeks it still wasn't done so I didn't pay him the other half of the job. Sipe's Sealcoating, one of the few good and reliable outfits around here, said he'd fix the lip for forty bucks so I'm actually ahead. Needless to say my blood pressure doubled and I used some very unchurchlike language when their boss showed up – I was fit to be tied. So I want you and your company to know again I appreciate your time and effort on my behalf and will recommend your company without hesitation and you as a contact in particular. Best regards and appreciation,
