Awning
Awning windows are hinged at the top and open outward, promoting airflow even when it’s drizzling. Their configuration makes them an excellent choice for hard-to-reach spots, such as above kitchen sinks or in compact bathrooms.
Bay and Bow Windows
Bay and bow windows project outward from the wall, adding depth to a room while offering wide, scenic views. They’re ideal for enhancing architectural character and maximizing natural light in living spaces.
Casement Windows
Casement windows are hinged at the side and open outward, delivering wide-open ventilation from top to bottom and simple interior cleaning. They’re frequently selected for their strong energy performance and secure, weather-tight closure.
Sliding Windows & Gliders
Sliding windows operate on horizontal tracks, so the sash glides open without taking up extra interior or exterior space. These glider styles are a smart option for rooms that face walkways, decks, or patios where swing clearance is limited.
Pass-Through Windows
Pass-through windows are designed to slide or fold completely open. Commonly installed between kitchens and outdoor living spaces, they create an effortless serving zone and make it easy to blend indoor comfort with outdoor entertaining.
Picture Windows
Picture windows feature expansive, fixed glass panels that frame clear, unobstructed views while flooding interiors with daylight. Their stationary, energy-conscious construction is perfect for highlighting beautiful outdoor surroundings.
Specialty Shapes
Specialty-shaped windows are crafted in distinctive geometric profiles that introduce a custom design accent to any room, enhancing architectural character and supporting unique layout or style goals.
Double Hung
Double-hung windows include two operable sashes that move up and down, allowing flexible airflow control and straightforward cleaning from inside the home. This classic configuration suits many architectural designs, combining everyday practicality with timeless curb appeal.
Single Hung
Single-hung windows feature a stationary upper sash and a lower sash that opens, delivering reliable ventilation with a traditional appearance. They’re an economical solution that complements both modern and classic home styles.

Frequently Asked 'Window' Questions
For Champaign’s climate, vinyl and fiberglass frames are popular because they resist warping in humidity and provide solid insulation in winter. Fiberglass is more rigid and durable, especially for larger windows, while vinyl offers a strong balance of performance and affordability. Wood frames insulate well but require more maintenance to protect against moisture. Aluminum is very strong but typically needs a thermal break to avoid heat loss and condensation in colder months.
Double-pane windows with low-E coatings and argon gas fill are usually sufficient for most homes, offering a strong balance of cost and efficiency. Triple-pane glass adds an extra layer of insulation and noise reduction, which can be helpful in very cold climates or noisy areas. However, triple-pane units are heavier and more expensive, so they make the most sense in rooms where comfort or quiet is critical. Review U-factor and solar heat gain coefficient (SHGC) ratings to compare actual performance between options.
Choose frames with good thermal breaks, such as vinyl or fiberglass, because they reduce temperature transfer that can cause condensation. Look for insulated glass units with warm-edge spacers, which keep the glass edges warmer and help minimize fogging. Proper weatherstripping and high-quality seals around the sash are key to preventing drafts. Also, ensure the window is sized accurately for the opening so insulation and sealants can work effectively.
Older homes often benefit from wood or wood-clad windows that preserve a traditional look while improving insulation. Fiberglass and composite windows can also be a good match because they can mimic wood profiles but require less maintenance in Champaign’s seasonal temperature swings. Look for custom or retrofit units sized to existing openings to avoid altering historic trim or masonry. Low-E glass and proper weatherstripping can significantly boost comfort without changing the home’s character.
Make sure the window system includes proper flashing components, such as sill pans and self-adhered flashing tape, to direct water away from the wall. The frame should be shimmed and fastened according to the manufacturer’s instructions so it stays square and operates smoothly. High-quality foam or fiberglass insulation around the frame, followed by a continuous interior air seal, helps prevent drafts. Finally, confirm that the exterior sealant is compatible with the frame material and siding so it adheres well and remains flexible over time.
