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.
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.
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.
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
Where you live makes a difference
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.
