Glazing Technologies on Replacement Windows

Choosing replacement windows in Newberg, OR is more than just picking a window frame, style, and size. It also means choosing the best glazing options for safety and energy efficiency. There are actually a lot of different options and features to consider when choosing the glass on replacement windows. Here are just a few of the most important things to keep in mind:

Double or Triple Glazing

Windows made with just one pane of glass do not offer much in the way of insulation, protection, or safety. That is why the standard for modern windows is two panes of glass sealed together to form an insulated glazing unit (IGU). But two panes of glass is not the only option. Some manufacturers also offer triple glazing on their replacement windows (three panes of glass). While most people think more is better, it is important to understand that the cost of an extra pane does not always equate to equitable energy savings. Talking to a window professional is the best way to figure out which options work best for the local climate.

Safety Glass Options

There are also different options for safety glass. Tempered glass means manufacturers cut the glass to size and then heat it to 600 degrees and rapidly cool it. This creates tension between the innermost and outermost parts of the glass to improve the tensile strength. The glass is harder to break, but if it does crack it shatters into smaller pieces that are not nearly as dangerous. Laminated glass means manufacturers adhere to two layers of glass to a polyvinyl butyral (PVB) interlayer. The glass bonds to the vinyl so that when it shatters much of the structure remains largely in place.

Noble Gas Fills

Manufacturers do not use normal air between the panes of glass on IGUs. It is too volatile and will expand and contract with temperature fluctuations. Noble or inert gasses do not share those same properties. They are considered inert because they have more density and do not have the same thermal expansion rates. That is why they are such a good option for insulation. The most common gases used for gas fills are argon, krypton, and xenon.

Window Tinting and Opacity

Manufacturers might also offer different glass tints or etching. Glass tints are laminates applied to the exterior surfaces of the glass meant to reduce heat gains and cut down on visible light. The most common tints include green, blue, grey, and bronze. But another thing homeowners might concern themselves with is privacy, especially in bedrooms and bathrooms. One solution is etched glass that obscures the view through the glass.

Low-E Glass

Last, but not least, are Low-E coatings. Manufacturers can apply ultrathin metallic layers to certain surfaces on the IGU. These will block the heat while still allowing natural light to filter through. These are great for homeowners who want a lot of sunlight, but not the heat gains that usually come with it.
