Picture Windows

Picture windows are fixed in place, so there are no mechanical parts to break. Great for winter time.

Bay windows are formed of multiple, usually quite large, panes of glass and allow lots of light to enter the building.



Single-Hung windows allow ventilation through a single operable lower sash.

Slider windows have fewer parts than conventional windows, making them a low-maintenance and cost-effective choice for residential homes.


Awning Windows

Awning windows provide great ventilation and can be placed higher in walls than many other types of windows.

Casement windows are energy efficient since they are not flexible by design.
