WHAT'S IN A WINDOW?
Windows are one of the most important features in your home today, both in function and in architectural interest. They let in light, bring the outdoors in, and add visual and functional interest to your home. Whether you are replacing your existing windows or installing windows for a new construction project, it helps to know what makes up a window before you start the selection process.

The Language of Windows

Casing
The trim around the top and sides of windows visible from inside and outside of house.

Jamb
A piece at the side or top of the frame around a window adjoining the moving parts. The top piece is called the "head jamb." The term "jamb" used alone refers to the side pieces.

Muntin
A narrow vertical or horizontal strip separating the panes of glass.

Rail
The horizontal top or bottom piece of a window sash.

Stile
A vertical side piece of a window sash.

Sash
The movable part of any window; the frame that holds the glass.

Sill
The horizontal piece at the bottom of a window frame, generally slanted down towards the exterior for water shed.

Glass Options

Sun Glass
Insulating glazing for improved energy efficiency. Soft gray tint. Application for maximum solar control requirements.

Low E, Low E with Argon
Insulating glazing for improved energy efficiency. Will help reduce U.V. penetration to help keep drapes, rugs, and furniture from fading.

Insulated
Primary purpose is to keep the inside heat or cold from being transferred outside the home.

Single, Double, or Triple Glazed
Refers to the number of pieces of glass: single is one piece, double is tow pieces with dead air between them, and triple is three pieces with dead air between.

Storm Panels
May be added to a single glazed window to achieve maximum energy efficiency. (*Not as efficient as Low E or Insulated Glass however.)

Grilles

Interior
Grilles are applied to the inside of the window only.

Exterior
Grilles are applied to the outside of the window only. Sometimes referred to as simulated divided lites (SDLs).

True Divided Lites
Grilles separate individual panes of glass. Often seen in more traditional New England homes.

G.B.G.
Grilles between the glass.

Exterior Finish

Wood
For those who like the traditional appearance of a primed wood window and the ability to change the wood's color on a whim. Must be refinished every 5-10 years. While the initial cost of a primed wood window is usually less than other types, in the long-term they are expensive. If you are not diligent about home maintenance, this is probably not the best choice for you.

Wood Interiors/Exterior Cladding
Great option for New England. The exterior cladding may be made of vinyl, aluminum, polyvinyl type paints, or a synthetic such as Ultrex. Choice may be limited depending on your home's environment. (*Some manufacturers do not warranty their product when exposed to salt water.)

Hollow Vinyl
Becoming a major factor in the market. They can be attractive, require no maintenance, are less costly, and quite durable. They have been used in the replacement market for years but we now see them in new construction also. Buyer beware! Many hollow vinyl windows are not of good quality.

PVC
Fairly new product on the market. Can be molded just like wood, is maintenance free, and has a solid feel and appearance. Can be painted or left in it's solid white finish. Has a wood frame for easy installation. Able to trim out the interior in a traditional manner.
