Today, there are 11 basic window types to choose from, below is a brief description of each type.

Casement Windows

Double and Single Hung Windows
The most common used windows today. It has panes that slide up and down in tracks called stiles. When open, these windows allow air flow through half of its size. In single-hung windows the top sash is fixed and can't be moved.

Awning and Hopper Windows
Similar in look to the Casement Windows, yet they tilt to open instead of slide (awning tilts inwards and Hopper tilts outwards). Both types allow air flow almost through their full size.

Horizontal Sliding Windows
These are actually Double-Hung or Single-Hung windows laid on their sides. Allow air flow through half of their size.

Fixed Window
Can't be opened or closed and are installed directly into a wall.

Glass Block Windows
Same as fixed windows, but installed like concrete blocks. Allow for privacy.

Bay Windows
Wide and decoratively impressive allow for 180° view. Consists of three adjacent windows or sections of windows in a series.

Bow Windows

Garden Windows
