Window Glass Types

Starting with the basics

Clear Glass

ProVia specializes in offering custom home windows, with a variety of window glass options that cover everything from decorative glass to privacy glass to energy efficiency enhancements. For most homeowners, a window purchase may start with the assumption of clear glass. But, even for clear glass, there are choices to make depending on the window application, its location in your home and your home’s exposure to extreme heat and cold.

CLEAR GLASS OPTIONS

Annealed glass is the standard for ProVia windows, with tempered glass being available as an upgrade. Here’s how they differ and why you want to consider which type is best for your home.

ANNEALED GLASS

This type of glass has been thermally treated and then slowly cooled to relieve any internal stresses. Annealed glass, which is more fragile than tempered glass, tends to break into longer, jagged shards which can cause significant injury. This glass is more cost effective than other types of glass. Annealed glass can be cut, drilled, notched and edge finished.

TEMPERED GLASS

This type of glass is manufactured through a process of extreme heating and rapid cooling of annealed glass, making it significantly harder and stronger than annealed glass. Tempered glass is four times stronger than annealed glass and can withstand temperatures of up to 470 degrees F. If tempered glass breaks, it shatters into small pieces less likely to cause injury. Depending on your state or local building codes, you may be required to use tempered glass for certain window applications, for instance, large-sized windows or those that are close to the floor, or windows near entry doors. Other applications for tempered glass might include homes where the likelihood of window breakage is higher, for instance, along a golf course.

SINGLE, DOUBLE OR TRIPLE STRENGTH

ProVia clear glass windows also can be ordered in single, double or triple strength, which is determined by the thickness of the glass. Single strength – 2.5 mm or 3/32” panes, annealed glass only Double strength — 3 mm or 1/8” panes, annealed or tempered glass Triple strength – 5 mm or 3/16” panes, annealed or tempered glass

ENERGY EFFICIENCY OPTIONS

In addition to choosing the strength of your clear glass windows, you’ll want to decide the level of energy efficiency you need, which is determined, in part, by where you live and the extremes of heat and cold that you experience in your area. ProVia offers a number of energy-efficiency options to meet the comfort and energy savings requirements of homeowners nationwide.

The distinctive look of stained window glass

Art Glass

When one thinks of stained glass windows, beautifully ornate churches from the Romanesque and early Gothic period come to mind. In those days, stained glass windows were made by artists who used lead to fuse together many individual pieces of colored glass to create intricate designs. The stained window glass created beautiful focal points on the exteriors of these grand buildings and even more visual interest from the inside when light poured in. Taking inspiration from these early works of art, ProVia’s Art Glass windows were created to elevate your home’s curb appeal with a custom exterior accent. With a variety of beautiful designs, several colors of resin bead and several color palettes to choose from, Art Glass affords homeowners the opportunity to infuse their own personality into their home design.

DISIGNS FOR ART GLASS WINDOWS

Choose from a diverse collection of Art Glass designs—some patterned from styles in our Decorative Glass collection—and fill with your choice of color (the total number of colors that can be applied varies by design). Or create a custom, personalized design of your own.

ANNEALED GLASS

This type of glass has been thermally treated and then slowly cooled to relieve any internal stresses. Annealed glass, which is more fragile than tempered glass, tends to break into longer, jagged shards which can cause significant injury. This glass is more cost effective than other types of glass. Annealed glass can be cut, drilled, notched and edge finished.

Create a focal point

Decorative Glass

Installing new windows offers homeowners the opportunity to express their creativity with design enhancements that add curb appeal while also increasing privacy. ProVia’s Decorative glass windows combine attractive designs made from clear beveled glass and caming with privacy glass panels that draw attention to your home.

Highly skilled craftsmen assemble hand-beveled glass accented with a variety of unique glass options by cutting, mitering and soldering each component into artistically designed patterns. That personal touch provides the purposeful visual character of small imperfections—textural waves, striations, random air bubbles and other natural effects—that make each piece of decorative glass unique. Homeowners can further customize their Decorative glass windows with a caming color choice that complements their home’s style.

Did you know that ProVia’s decorative glass is hand-assembled by skilled craftsmen—from the caming that outlines each unique pattern to the individual pieces of glass showcased in every style? Watch as a featured decorative glass design carefully comes together from start to finish in this short video.

ProVia’s privacy glass designs are available for most of our window brands in double hung, single hung, slider, casement, awning and picture window styles.

Control UV exposure

Complement your home's style

PATIO DOORS & WINDOWS WITH GRIDS

Buying new windows or patio doors offers a host of choices that can enhance your home’s curb appeal, including the addition of window grids. Adding patio doors or windows with grids is a smart choice for certain home exterior styles, such as Cape Cod, Colonial, Craftsman, or Tudor, to maintain the authenticity of the architecture. ProVia offers internal and exterior grids, with design options for each.

INTERNAL PATIO DOOR & WINDOW GRIDS

Internal grids consist of grids placed between two panes of glass, which provides the authentic look of real grids while making glass cleaning quick and easy. Each style of ProVia’s internal patio door and window grids are available with triple glazed glass (the addition of a third pane for added energy efficiency) or double glazed glass (ecoLite only available with double glazed).
