Single-Hung and Double-Hung Windows: Single-hung windows have a fixed upper sash and a lower sash that can be raised or lowered. Double-hung windows have two operable sashes that can both be opened and closed. Benefits: They provide good ventilation control, allow for easy cleaning, and are suitable for most architectural styles. Casement Windows: Casement windows are hinged on one side and open outward, often operated with a crank. Benefits: They offer unobstructed views, excellent ventilation when fully opened, and a tight seal when closed, providing energy efficiency. Awning Windows: Awning windows are similar to casement windows but are hinged at the top and open outward from the bottom. Benefits: They allow for ventilation even during rain since the window acts as an awning, providing protection from the elements. Sliding Windows: Sliding windows consist of two horizontal sashes, where one or both can be moved horizontally along a track. Benefits: They are easy to operate, provide a modern look, and offer expansive views with large glass areas. Picture Windows: Picture windows are large fixed windows that do not open and are designed to provide unobstructed views and maximize natural light. Benefits: They allow for ample natural light, enhance views, and are energy-efficient due to their fixed nature. Bay and Bow Windows: Bay windows are a combination of three or more windows projecting outward from the wall, typically with a larger center window flanked by smaller side windows. Bow windows are similar but have a more curved appearance. Benefits: They create a sense of space, increase natural light, provide panoramic views, and can be used as additional seating or storage areas. Skylights: Skylights are windows installed on the roof or ceiling to allow natural light to enter from above. Benefits: They bring abundant natural light into interior spaces, provide ventilation options, and can contribute to energy savings by reducing the need for artificial lighting during the day.
