Awning
Awning windows are hinged at the top and open outward, promoting ventilation while helping shield interiors from light rain. Their configuration makes them a smart choice for tight or elevated spaces, such as above kitchen sinks or in smaller 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 are ideal for enhancing architectural character, creating cozy seating areas, and maximizing natural daylight.

Casement Windows
Casement windows are hinged at the side and open outward, delivering wide-open ventilation from top to bottom and allowing simple cleaning from inside the home. 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 ideal for rooms that overlook walkways, decks, or patios where a swinging sash might get in the way.

Pass-Through Windows
Pass-through windows are designed to slide or fold completely open. Commonly installed between kitchens and outdoor living areas, they create a convenient serving counter and make it easy to blend indoor comfort with your backyard entertaining space.

Picture Windows
Picture windows feature expansive, fixed glass panels that frame clear views and flood interiors with natural daylight. Their stationary, energy-conscious construction is perfect for highlighting scenic outdoor vistas.

Specialty Shapes
Specialty-shaped windows are crafted in distinctive geometric profiles that bring a custom design touch to any room, adding architectural character or aligning with unique project specifications.

Double Hung
Double-hung windows include two operable sashes that move independently, promoting flexible airflow and simplifying cleaning from inside. This timeless style complements many home designs while balancing everyday performance with curb appeal.

Single Hung
Single-hung windows feature a stationary upper sash and a lower sash that opens for airflow, delivering a traditional appearance with reliable ventilation. They provide a budget-friendly option that suits both classic and modern homes.

Frequently Asked 'Window' Questions
For Illinois’ mix of hot summers and freezing winters, vinyl, fiberglass, and composite frames typically perform best. Vinyl is affordable and low-maintenance, while fiberglass and composite frames are more rigid and stable, resisting warping and expansion. Wood offers a classic look but needs regular sealing or painting to handle moisture and temperature swings. Aluminum is strong but less energy-efficient unless it includes a thermal break.
In East Peoria’s climate, look for double- or triple-pane glass with low-E coatings and argon or krypton gas fills between the panes. These features help keep heat inside during winter and block heat gain in summer, lowering energy bills. Check the window’s U-factor (lower is better for insulation) and Solar Heat Gain Coefficient (SHGC) to match your home’s orientation. South- and west-facing windows often benefit from lower SHGC to reduce summer overheating.
Vinyl windows are usually more budget-friendly and require very little maintenance, but they can expand and contract more with temperature changes. Fiberglass windows cost more upfront but are stronger, more dimensionally stable, and often have a longer service life. Fiberglass frames can also be painted and tend to hold larger glass areas with slimmer profiles. Your choice often comes down to budget, desired lifespan, and how much maintenance you’re willing to do.
Use high-quality flashing tape and sealants around the window opening to create a continuous water and air barrier. Low-expansion spray foam or backer rod with sealant around the interior perimeter helps insulate without warping the frame. Always follow the manufacturer’s installation instructions, including proper shimming and fastening, to keep the window square and operable. Adding a properly installed sill pan can provide extra protection against water intrusion at the bottom of the window.
In higher-moisture areas, fiberglass, composite, and high-quality vinyl windows are usually better choices than bare wood because they resist rot and swelling. If you prefer the look of wood, consider wood-clad windows that protect the exterior with aluminum or fiberglass cladding. Look for corrosion-resistant hardware and durable exterior finishes to handle humidity and potential exposure to wind-driven rain. Proper sealing and flashing are especially critical in these locations to prevent long-term moisture damage.
