Tilt-In Window

Your Pinnacle Window Double-Hung utilizes special hardware for easy cleaning. Both sashes tilt-in for easy cleaning from inside your home.

Tilt-In Window




Double-hung windows are the most common choice for homebuilders. Double-hung windows contain two panes which both slide vertically.

Awning Hopper


Awning - Similar to a casement window as it also opens on a hinge. The main difference between the two styles is that an awning window opens horizontally rather than vertically, which somewhat limits how far it can be opened. One benefit of this set-up, however, is that awning windows can often be left open during storms because the open pane deflects rainfall.

Hopper - Essentinally the same as an awning window, but opens at the top rather than the bottom. For obvious reasons, this style does not direct rain away from the interior.



Like doors, casement windows pivot on hinges. This style often opens outward and may be operated with a hand-crank. According to Better Homes and Gardens, casement shapes tend toward the tall and narrow, so wide wall openings usually feature several.

Picture Transom Fixed


A picture window is a fixed window that does not open or close.  Picture windows are often used as transoms (side lights) next to a large window or door or as a large window to provide an expanded view.



These windows open horizontally. On a single slider, only one side operates. On a double slider, both sides operate. We make a variety of sliding windows which can also be tilted in, swing in, or lifted out for easy cleaning.
