Types of Replacement Windows We Offer
We carry a wide variety of styles to match your home and budget. Whether you’re tackling a full home upgrade or just replacing a few drafty windows, we’ve got the right fit.
- Double-Hung Windows: These are the classic choice for easy operation and ventilation. Both sashes tilt in, making them simple to clean from inside your home.
- Casement Windows: Hinged on the side and crank-operated, these windows swing open like a door. They’re perfect for catching breezes and letting in maximum airflow.
- Awning Windows: Hinged at the top, awning windows open outward to create a canopy-like effect. They’re ideal for basements or bathrooms and can be left open during light rain.
- Sliding Windows: These windows slide horizontally along a track, offering a sleek, low-profile design. They’re best suited for wide window openings and modern aesthetics.
- Picture Windows: A fixed, non-operable style that maximizes your view and brings in natural light. Ideal for showcasing the outdoors and improving energy efficiency.
- Bay Windows: These windows extend outward from your home, usually in a three-panel configuration. They create extra interior space and add architectural interest from the curb.
- Bow Windows: Similar to bays, but with a gentler curve and four or more panels. They offer a broader, panoramic view and a unique design element for larger spaces.
- Garden Windows: These mini greenhouse-style windows project out from the wall and are often installed in kitchens. They create a bright nook perfect for plants or displaying decor.
- Custom Windows: Available in a range of geometric shapes like triangles, hexagons, and more. These are great for accent areas or unique architectural details.
- Round Top Windows: These arched windows add a soft, elegant touch to entryways or above standard rectangular windows. They help bring in light while enhancing curb appeal.
- Hopper Windows: Hinged at the bottom and opening inward, these compact windows are commonly used in basements or small bathrooms. They provide secure ventilation and are easy to operate.
Energy Efficient Windows That Help You Save
Energy efficiency isn’t just a perk, it’s one of the smartest reasons to replace your windows. All of our windows meet or exceed the latest ENERGY STAR® 7.0 standards. That means better insulation, reduced energy bills, and a more comfortable home all year long.
Our windows also include advanced Low-E glass, which reflects infrared light to manage indoor temperatures more effectively. That means cooler summers, warmer winters, and less strain on your HVAC system. And because Frederick sees everything from hot humidity to winter chill, this kind of performance matters.
You’ll notice the difference in comfort, and over time, on your utility bill too.
