Double Hung Windows

Double hung windows are a versatile and timeless window style that offers both aesthetic appeal and practicality. Unlike single hung windows, both the top and bottom sashes in double hung windows are movable and can be opened. This design allows for excellent ventilation control, as you can choose to open either the top or bottom sash or both simultaneously. Double hung windows are known for their classic appearance, energy efficiency, and ease of cleaning, as they often come with tilt-in sashes. They are suitable for a wide range of architectural styles and are a popular choice for homeowners seeking functionality and style.

Integrity Single Hung

Single Hung Windows

Single hung windows are a classic and space-efficient window style known for their simple design and practicality. In single hung windows, only the bottom sash is movable, typically sliding upward to open while the top sash remains fixed. This design is easy to operate and provides effective ventilation control. Single hung windows are popular for their affordability, energy efficiency, and timeless appearance. They are a great choice for homeowners seeking a traditional window option that complements various architectural styles while maximizing natural light and airflow.

Marvin Ultimate Casement 13

Casement Windows

Casement windows are a popular and versatile window style known for their practicality and elegant design. These windows are hinged on one side and open outward with the help of a crank or lever, allowing for easy operation and excellent ventilation control. Casement windows provide unobstructed views and a tight seal when closed, enhancing energy efficiency and security. They come in various materials and styles, making them suitable for both traditional and modern architectural designs. Casement windows are an excellent choice for homeowners seeking functionality, aesthetics, and energy savings.

Marvin Awning Ohana 1

Awning Windows

Awning windows are a unique and functional window style known for their outward-opening design. Hinged at the top and operated with a crank or lever, awning windows open from the bottom and tilt outward, creating an “awning” effect. This design allows for excellent ventilation, even during light rain, as the sash acts as a shield against precipitation. Awning windows are popular for their ability to bring fresh air into a space while maintaining security and energy efficiency. They are a stylish choice for modern and contemporary architectural designs and can be installed individually or combined with other window styles for a custom look.

Integrity Glider 19

Glider Windows

Glider windows, also known as sliding windows, are a practical and space-saving window style characterized by their horizontal opening mechanism. These windows feature sashes that slide horizontally on tracks, allowing for smooth and effortless operation. Glider windows provide unobstructed views and ample natural light, making them an excellent choice for rooms with scenic views or limited vertical space. They are known for their energy efficiency, easy maintenance, and modern aesthetic, making them suitable for a variety of architectural styles, especially contemporary and minimalist designs.

Marvin Bow AC

Bay & Bow Windows

Bay and bow windows are exquisite and distinctive window styles that enhance both the interior and exterior of a home. Bay windows typically consist of three large window panels, with a central fixed window flanked by two operable windows at angles. Bow windows, on the other hand, are comprised of four or more window panels, forming a gentle curve or arc.

These windows create a sense of spaciousness and bring abundant natural light into a room. They also offer additional seating or display space, as the extended ledge can be used for seating or decorating. Bay and bow windows are often chosen for their ability to make a room feel larger and more inviting while adding architectural character to a home’s facade.

These windows are popular in various architectural styles, including traditional, Victorian, and modern homes. They provide an elegant and timeless design element that enhances both the interior and exterior beauty of the house.
