Before you shop for new windows for your home, it's good to know a few important details about windows in general, including their various styles and the different types of glass that is used. This will ensure you choose the right windows for your home in particular, and avoid any mistakes in ordering. Note a few terms and phrases you'll see when you go window shopping or meet with a window installer, so you find the best windows for your home.

Double and triple-glazed versus film

Glazing does not refer to a type of coating put on the windows, like when you glaze a donut! Instead, the words glazing or glaze refer to the actual panes of glass in the window; double-glazed windows have two panes of glass that are attached or sealed together, and triple-glazed have three panes.

This is important to note, as you don't want to confuse glazing with window film, as film is actually applied over the glass itself. Double-glazed or triple-glazed windows add insulation from outside sound, heat, and cold, but may not add shade to the home's interior. Window film, on the other hand, may not offer much insulation, but may cut down on light that comes through the windows, reducing glare and protecting plants and upholstery from fading and damage.

Direct glaze

A direct glaze window has no sash, but is mounted right to the frame that is cut into the home. This type of window is stationary, so you can't open or close it, but it can be a good choice for when you want maximum sunlight or the best view out the window, such as for a living room or for surrounding a bathtub. Without a sash, more glass is exposed for a larger window and better view outside. Direct glaze windows can be double-glazed or triple-glazed if you need that added insulation, but will have the smallest surrounding frame possible.

Glass size

It's important to note that the glass size of your windows may be different than the window size. Glass size refers to the size of the actual pane of glass that will be installed, whereas the window size includes the window frame and any trim pieces that are added. If you're thinking of measuring for new windows yourself, don't confuse these two sizes; you might order a large glass size, thinking it's the same as the window itself, and find that the piece is then too large to fit into the area that's been cut for the windows.
