The Three Most Popular Window Styles in American Homes
Style affects more than looks. It determines how a window opens, how easy it is to clean, how well it seals against drafts, and how much it costs to install. Here's how the three top styles stack up.
Double-Hung Windows
$350 – $850 installed, per windowAmerica's best-selling style. Two sashes slide vertically, and both typically tilt inward so you can clean the exterior glass from inside your home — a huge plus on second stories.
Pros
- Most affordable style to buy and install
- Tilt-in sashes make cleaning simple
- Works with nearly every home style
- Safe partial ventilation from the top sash
Cons
- Slightly less airtight than casement seals
- Only half the opening ventilates at once
Casement Windows
$450 – $1,000 installed, per windowHinged on the side and cranked open outward like a door. When closed, the sash presses firmly against the frame, giving casements the tightest seal of any operable window.
Pros
- Best energy efficiency of operable styles
- Opens fully — maximum airflow
- Crank handle is easy over sinks and counters
- Unobstructed glass for clear views
Cons
- Costs more than double-hung
- Crank hardware can wear over time
- Can't open onto walkways or decks
Bay Windows
$1,800 – $6,500 installedA three-panel unit that projects outward from your home — usually one fixed picture window flanked by two operable windows at 30–45° angles. Adds floor space, light, and serious curb appeal.
Pros
- Dramatically increases natural light
- Adds an interior seat, shelf, or nook
- Boosts curb appeal and resale value
- Panoramic multi-angle views
Cons
- Highest cost — often needs structural work
- Longer, more complex installation
- Roof cap over the bay needs maintenance
Vinyl vs. Fiberglass vs. Wood: Which Frame Should You Choose?
Frame material drives roughly 40–60% of your window's price — and determines how it looks, insulates, and holds up over 20+ years. There's no single "best" material, only the best fit for your budget, climate, and home.
Vinyl Frames
$300 – $800 per window installedThe most popular replacement window frame in the U.S. — and for good reason. Vinyl (PVC) never needs painting, resists moisture completely, and insulates well thanks to hollow, multi-chambered frames.
Pros
- Lowest cost of the three materials
- Zero maintenance — never paint or seal
- Good insulation; won't rot or rust
- Widely available, fast installation
Cons
- Limited colors; can't be repainted easily
- Can expand/warp in extreme heat
- Thicker frames = slightly less glass area
Fiberglass Frames
$550 – $1,300 per window installedThe performance pick. Fiberglass is up to 8× stronger than vinyl, expands and contracts at nearly the same rate as glass (so seals stay tight), and lasts 40–50 years with minimal care.
Pros
- Extremely strong and dimensionally stable
- Excellent insulation in any climate
- Slim frames = more glass, more light
- Paintable; longest lifespan of the three
Cons
- 30–70% pricier than comparable vinyl
- Fewer brands and installers offer it
Wood Frames
$700 – $1,600 per window installedThe classic. Nothing matches the warmth and character of real wood, and it's naturally one of the best insulators. Modern wood windows are often "clad" in aluminum or fiberglass outside to cut maintenance.
Pros
- Unmatched beauty and architectural charm
- Superb natural insulation
- Paint or stain any color, inside and out
- Often required in historic districts
Cons
- Highest cost and highest maintenance
- Vulnerable to rot, swelling, and insects
- Needs repainting/sealing every 3–7 years

Set your per-window budget first.
Under $500/window points to vinyl double-hung. $600–$900 opens up casements and fiberglass. $1,000+ puts wood and specialty shapes on the table.
-
Match the material to your climate.
Harsh winters or scorching summers favor fiberglass or casement-style sealing. Mild climates make vinyl an easy value win.
-
Match the style to the room.
Casements over sinks and behind furniture, double-hung in bedrooms, a bay window where you want a focal point in the living or dining room.
-
Think in total cost of ownership.
A cheaper window that lasts 20 years can cost more per year than a fiberglass window that lasts 45 — especially once energy savings are counted.
