At Atlas Glass, we find that most people
think that window
design is all about glass. This
is understandable! But the truth is, windows are comprised of numerous parts
and accessories, each of which has a definite name and purpose within the
window industry that not many know of.
If you’ve been referring to parts of the
window as the ‘top bit’ or ‘bottom bit’, you might want to brush up your
knowledge on window terminology. Join in for a crash course to learn what each
part is called, and the purpose it serves!
Every window has three basic parts – the
frame, the sash and the panes.
If you’re looking at your window head-on, the
frame is the piece surrounding the window. Frames surround the entire window
system and provide support.
The sash is the moveable part, both
horizontally or vertically, that holds the glass in place. With casement
windows, sashes swing open, on double-hung and single-hung windows, they
usually slide up and down to open and close the windows.
In simple terms, panes are the glass. Panes
are connected to sash or muntins, which are grid-like bars that feature in some
windows. Windowpanes can be single, double or even triple glazed to provide
insulation. Double-glazing refers to creating a window that consists of two glass panes separated
by vacuum or gas to reduce heat transfer.
The Parts of a Frame
The basics can be broken down even further
into the sum of their components. If you delve deeper, you can see that
there are innumerable small yet intricate parts that make up a window and
assist in its smooth functioning.
Let’s start with the frame.
This component of a window can be broken down into three smaller components:
the jamb, the sill, and the head. There’s also the casing, which is a very
important aspect of window design.
Jambs are the vertical boards that are found
between the head and the sill.
Sill is down the bottom, where you can rest
your arms if your sitting by the window!
Opposite to the sill, the head is the top
horizontal part that forms the top of the frame.
Casing is the decorative frame or moulding
that is found around the window to cover the space between the jamb and the
wall. Sometimes, it can be seen covering space between two window frames.
The Parts Related to the Sash
While these parts aren’t a part of the
actual sash, they do help it to function. The parts included depend on the type
of window installed.
The Balance is found right at the center of
the window. True to its name, it provides balance as the sash opens and
Usually found on double-hung windows, this is
the part where two sashes meet in the middle – the bottom part of the upper
sash and the upper part of the bottom sash.
The Jambliner is a strip that is usually
found on the side of the window frame. It gives the window sash a snug fit.
A lift, as suggested by the name, is what
makes it possible to raise the window in case of single or double hung windows.
A sash lock is the mechanism that is used to
lock single and double hung windows. It is usually located on the operating
sash and is used for preventing the sash from opening in its frame.
A stool is the horizontal board on the inside
of the window, against the sash.
