Window Replacement Terminology to Know

Window replacement doesn't have to be overwhelming, but you may want to do a little research on your options before hiring a window replacement contractor.

Here are some basics of some of the terminology you may come across when researching window replacement options.

Glass Types

You'll have a variety of glass options to choose from when replacing windows. Manufacturers create different types of glass by using different techniques during the manufacturing process, which can enhance the performance, safety, and even appearance of the glass. Here are some terms to be aware of:

• Tempered glass: This type of glass is treated with extreme temperatures to make the glass stronger and reduce sharp shards when the window breaks.
• Float glass: This is typically just your basic large sheet of glass. The term refers to the manufacturing process, which involves allowing melted glass to float in a flat sheet.
• Laminated glass: This glass is constructed of two layers of glass fused to an inner layer of tough plastic, which holds the glass in place in case of shattering.

The type of glass you buy can affect the performance of your windows, which is why different types of glass are better in some situations than others. For instance, tempered glass is often used for glass doors. If the door slams, the stronger tempered glass will be less likely to shatter and if it does, the glass pieces will be less likely to cause injury.

Window Type Terminology

Window shapes can vary widely, from basic sliding windows to fully customized curved windows. Here are a few of the main window types you'll be choosing from for a typical home:

• Sliding windows: These windows slide horizontally, with no tilt. This sliding motion is similar to that of a french door.
• Awning windows: An awning window is often placed above a door or larger window, and opens by tilting outwards. These windows may open using a crank mechanism.
• Single or double hung windows: These windows have two window sashes, one above the other. A single hung style has one sliding half, whereas a double hung has two.
• Casement windows: A casement window opens with a crank. But instead of operating on a horizontal axis like awning windows, these windows open on a vertical axis.

Often, if you're replacing a window, you can replace it with a different type of window relatively easily as long as the window dimensions are the same.

Glass Surface Treatments Terminology

A glass surface treatment can change glass performance by changing the surface of the glass. Adding a coating, for instance, can alter the appearance and performance of the glass.

Here are a few terms you need to know:

• Acid etching: This process uses acid on the surface of the glass. Etching can produce a highly frosted appearance and boost privacy.
• Sandblasting: Sandblasting is another mechanism for producing frosted glass. This technique allows for decorative frosted patterns or designs.
• Window tinting: Window tints can be added during manufacturing. You can also add tinted films later to reduce glare and increase privacy.

These are a few of the terms you'll need to know when considering functional or decorative finishes for your window glass.

Efficiency Terminology

Even an older, inefficient window can be replaced by a well-insulated, efficient window. Here are a few efficiency terms that can help you navigate window replacement possibilities.

• Low-emissivity glass: This is a type of glass with a microscopic coating that reflects radiant heat, helping to reduce unwanted heat transfer.
• Double- or triple-glazed windows: These have multiple layers of glass, with a non-conductive layer (typically noble gas or a vacuum) between them to cut down on heat loss.
• R-value: This refers to how well-insulated a window is. A double- or triple-glazed window will have a better R-value than a single pane of glass.

As you can see, different types and configurations of glass can vary widely in energy efficiency.
