Radius Window |
This window is the same as a single hung window except the top portion is oval, not straight. |
Rail |
The horizontal sections of the sash. |
Retrofit Window |
A window designed to replace an existing window without removing the original frame. |
Sash |
The part of the window that moves, whether it be up or down, left or right, or in and out. |
Sash (pivot) Alignment System |
An exclusive, hinge-type system used on hung windows. This system attaches the sash to the balance, creating perfect alignment between the sash and frame, while allowing the sash to tilt inward for cleaning. |
Sash Stop |
A molding that covers the joint between the window sash and the jamb to stop the travel of the sash at the top and bottom of the window. |
Screen |
A woven mesh of metal, plastic, or fiberglass stretched over a window opening to permit air to pass through but preventing insects from passing through. |
Sculptured Grid |
|
Sill |
The horizontal members of the bottom portion of the window frame. Usually made from aluminum, swiggle, composite materials or stainless steel. |
Simulated True Divided Grid |
A grid that is designed to achieve the look of a true divided grid, without actually dividing the panes of glass. It is actually an external grid on one large glass unit. |
Single Hung Window |
Only the bottom sash of the window operates while the upper sash is stationary. |
Single Slider |
A sliding window with one moving sash. |
Slider |
Sliding windows and doors with sashes that only move horizontally, along grooves or tracks, while other parts remain stationary. |
Sliding Patio |
|
Spacer |
A part that seals two panes of glass in a double-pane window system, and forms a dead air space between them. |
Stile |
The vertical edges of a window, door or screen's sash panel that connects the lock rail and the lift rail. |
Stop |
The molding on the inside of the window frame against which the window sash closes, or in the case of a double-hung window, the sash slides against the stop. |
Super Spacer |
A spacer that is foam and fiberglass based. This is the least conductive spacer. |
Sweep Lock |
A sash fastener located at the meeting rails of a double-hung window which rotates and clamps the two rails closer together. |
Tilt and Turn Window |
The tilt and turn window is the same as a single hung window, except the sash can be tilted or turned in addition to the normal up and down motion. |
Tilt Latch Pull |
A latch that allows the sash to tilt in so that the outside of the glass can be cleaned. |
Triple Pane |
A unit with three pieces of glass separated by two spacers. These windows are designed for areas with prolonged exposure to extreme heat or cold. |
True Divided Grid |
A grid that divides a window pane into a number of small mini-panes that are sealed and completely separated from each other. Only available in wood products. |
V-groove Grid |
|
Vinyl Extrusions |
Just like the aluminum frames, vinyl window frames are extrusions (prefabricated cuts). But because vinyl is not as rigid as aluminum, internal hollow chambers are often added to provide strength, and increase performance. |
Weld |
To join together by applying heat, pressure or sometimes with an intermediate filler material that has a high melting point. |
