Windows 101: Window Glass Options Guide


Glass is an important part of windows and patio doors. There are multiple window glass options to fit the needs of the environment and climate. We’ve gathered all the glass options offered in JELD-WEN products in this handy guide.

LoĒ³-366® glass

A high performing glass with insulating argon gas, LoĒ³-366 helps homes stay cool in the summer and warm in the winter. Use of this glass can help windows qualify as ENERGY STAR® products. This glass allows light in but not heat. The view is also clearer compared to a tinted glass. It also protects against fading of interior furnishings by blocking up to 95 percent of the sun’s ultraviolet rays.

The glass is manufactured using a sputter coating process and contains a third layer of silver coating.

Neat® glass

Neat glass was developed to be virtually self-cleaning. It works as a coating that allows for easier cleaning. It uses the sun’s UV rays to loosen dirt so water can rinse it away. The titanium dioxide layer reacts chemically with the sun’s UV rays and causes organic materials that are on the glass to decompose.

It works on cloudy days as well. Up to 80 percent of UV radiation gets through cloud cover. A thin layer of silicon dioxide creates an ultra-smooth surface. Because all the microscopic peaks and valleys have been filled in, debris can slide off windows during rain. Water disperses evenly and rolls off, reducing water spotting.

Preserve® glass

This protective window film keeps windows safe and clean during construction. It also protects from scratching. Preserve is applied to both outer and inner surfaces in overlapping layers. It eliminates the issue of “ghosting” labels leaving imprints. It also helps crews work around windows without the concern of damage or the time to wrap and secure windows.

The coating peels off in one smooth motion. It contains no harmful chemicals and requires no special disposal.

It’s a fantastic way to save time and protect valuable materials.

Tinted glass

Tinted glass reduces glare. It’s ideal for areas that receive a lot of direct sunlight. Tints available include green, bronze, reflective gray and reflective bronze.

Insulated glass

High-performance Low-E glass combined with advanced spacer systems and gas sealed between the panes are key elements that provide an energy efficient window. Options include double-pane and triple-pane. A double-pane has an intercept spacer. Triple-panes have super spacers.

Textured glass

Textured glass gives you the opportunity to let light in while maintaining privacy. Many options are available including these five choices: Glue Chip, Rain, Obscure, Narrow Reed and Seedy Reamy.

Laminated glass

Laminated glass consists of panes of glass with an invisible interlayer, sandwiched together to create an extremely sturdy glass unit. This provides increased protection for home safety and from incidental impact. It also provides an improved barrier against sound and harmful UV rays.

Tempered glass

This type of glass is treated with heat, so it can withstand greater force or pressure on its surface. It also will not break into sharp pieces.


This glass stands up to strong impacts from windborne debris as well as harsh coastal conditions. It’s the industry’s leading laminated glass technology that can withstand a nine-pound piece of lumber striking it head-on at approximately 34 miles per hour. It also reduces sound transmission, blocks up to 95 percent of harmful UV rays and enhances home security.

Safe impact-resistance

During a severe storm, a broken window can affect a home’s structural integrity. Windows and patio doors with ImpactGard glass are designed to resist impact. Even if the glass cracks, the fragments will adhere to the interlayer, so the shards remain within the frame. ImpactGard protection also meets the nation’s toughest building codes. These codes specify that windows must withstand a nine-pound 2×4 traveling at 50-feet per second (34 miles per hour).

Secure forced-entry resistance

Windows and patio doors with ImpactGard glass resist forced entry. Because the interlayer separating the panes helps resist a potential intruder’s glass cutter, break-ins are less likely.
