Vinyl Windows: The Best Window Material for Most Homeowners
A vinyl window is the best option for most homeowners. Vinyl is extremely low-maintenance and relatively economical compared to other window material options. Vinyl frames are lightweight and recyclable, making them popular choices for both replacement windows and new window installation.
Are vinyl windows energy efficient?
The top vinyl window brands are extremely energy efficient. Quality vinyl frames are equipped with strong insulation, which guards against air leaks in and out of your home. Vinyl windows coupled with energy efficient window treatments — like cellular shades or Roman shades — can save you up to 15% a year on home energy bills.
Homeowners who want the most energy efficient vinyl windows should opt for triple glazing. Triple pane windows significantly reduce heat loss in the winter, and keep air conditioning from leaking in summer months. Look for krypton-filled units — the addition of krypton gas to the existing vinyl window insulation increases your protection against heat loss.
The pros and cons of vinyl windows
Pros:
Highly energy efficient
Lightweight
Well insulated
20+ year lifespan when properly managed
Fire resistant
Noise resistant
Good variety of colors and styles
Cons:
Weaker than metal and fiberglass frame options
Cannot paint or stain
May warp and bend if exposed to high temperatures
Small risk of fading over time
What do vinyl windows cost?
A small vinyl window costs $250-$450 to purchase. Larger vinyl window frames cost anywhere from $475 to $950 per window.
The best option for most homeowners is a double-hung or casement window. The average vinyl window of these styles costs between $450-$675 per window. However, choosing a brand-name like Pella can often double the costs to $1,350 per window before installation.
Add roughly $125-$150 per window if you prefer double-pane vinyl windows.
The installation labor typically runs $300-400 per window

Fiberglass Windows: Excellent Durability and Energy Efficiency
Fiberglass window frames are among the most durable residential window options available. Fiberglass windows contain an interwoven structure of glass fibers and resin core. This creates a strong, flexible structure that expands and contracts with the temperature and elements.
The strong construction of a fiberglass window leads to exceptional energy efficiency and noise cancellation. But you'll pay for the upgrade — the average cost of a fiberglass window is 1.5x-2x greater than a comparable vinyl frame.
Are fiberglass windows energy efficient?
On merit alone, fiberglass windows are the most energy efficient window material among the 5 most popular options. They perform slightly better than vinyl frames regarding heat loss, sealing air leaks and providing added insulation.
We think that the potential gain in energy savings doesn't quite offset the cost increase of fiberglass windows vs. vinyl windows. However, homeowners who live in extremely cold or hot climates will benefit greatly from the upgrade.
The pros and cons of fiberglass windows
Pros:
Excellent resistance to heat and cold
Strong protection against the elements and severe weather
Very energy-efficient
Noise resistant
Waterproof
Highly durable, long-lasting material with minimal upkeep
Cons:
Expensive compared to other popular window material options
Harder to source than vinyl and aluminum windows
Less able to be customized and altered
Cost more to install than other window options (due to labor)
What do fiberglass windows cost?
A standard double-hung fiberglass window of medium size costs roughly $500-1,250. The average fiberglass casement window or picture window costs between $650-1,500.
Fiberglass windows are typically more difficult to install than other window frame materials. Expect to pay an extra 20-25% for labor costs when hiring a window installation company.

Composite Windows: Premium Durability at a Premium Price
If money isn’t a factor in your window material selection process, consider a composite window. Composite windows blend the low maintenance, and durability of fiberglass with the great look and insulating power of wood. You’ll pay more than every other option on our list — in return, you’ll get premium durability and great looks, all with minimal maintenance required.
Are composite windows energy efficient?
Composite windows score well on energy efficiency rankings, particularly in guarding against heat loss. Composite window materials provide excellent thermal insulation, keeping your home warm (and energy bills down) in cold winter months.
We think fiberglass and vinyl window materials score about as well as composite frames in most energy efficiency categories. If this is your primary criteria for choosing a window material, we don’t think the energy savings of composite windows are quite big enough to justify the price tag.
The pros and cons of composite windows
Pros:
Exceptional thermal insulation compared to all other window materials
Lifespan of 35-40+ years when properly handled, installed and maintained
Engineered to resist moisture and rot, and highly unlikely to warp
Excellent in harsh climates, especially in cold weather
Cons:
Higher price tag than all competing window material choices
Not a cost-effective window material option for most homeowners
Susceptible to fading and discoloration over long periods of exposure to sunlight
Less color and design versatility than other window materials, especially wood and vinyl
What do composite windows cost?
The average cost to purchase and install composite windows is $700-$1,200 per window. However, most homeowners who select composite windows opt for premium products to maximize their durability benefits. Premium composite windows start at $1,250 per window before installation.
Installation costs will also run more expensive as composite windows cannot be fusion welded.

Aluminum Windows: Budget Friendly, But Not Energy Efficient
Aluminum windows are ideal for homeowners whose primary concern is lightweight, inexpensive material. However, aluminum is among the worst window materials in terms of energy efficiency.
If you choose aluminum windows, make sure you live in a temperate climate that doesn’t get too hot or cold. The upfront savings you gain by choosing aluminum will evaporate over time with an increase in your home heating and cooling bills.
Are aluminum windows energy efficient?
Not particularly. Aluminum windows are known for heat loss, and cause energy bills to increase during cold winter months. A weak seal also leads to condensation issues in aluminum windows, which can lead to mold and mildew growth.
We think the inexpensive nature of aluminum windows doesn’t make up for their subpar energy efficiency. The average homeowner with aluminum windows can see home energy bills increase by up to 8-10% per year.
The pros and cons of aluminum windows
Pros:
Extremely lightweight frames are easy to handle and install
Low maintenance compared to wood and other natural materials
Average lifespan of 20-25 years per window frame — 40+ years if well-maintained
More affordable material option than fiberglass and vinyl frames
Cons:
Average to poor energy efficiency ratings
Aluminum materials may corrode over time
More susceptible to condensation between window panes
Much thinner than wood windows and fiberglass windows
Very specific in terms of style — won’t look good in wood-based home designs
What do aluminum windows cost?
Mid-range aluminum windows cost between $400-$800 to purchase and install. A double-hung aluminum window is slightly more expensive, ranging between $500-$1,100 to buy and install.
You’ll pay less for aluminum window installation than fiberglass, as the material is far lighter and easier to handle. However, this savings is offset by a poor energy efficiency rating — aluminum is one of the worst material options when it comes to home heat loss.

Wood Windows: Luxury Design with an Luxury Price Tag
Wood windows are the choice of homeowners who prioritize design aesthetics above all else. Customization options are nearly endless in terms of color, grain and style — wood windows bring a natural look and feel to home design, especially in older and vintage houses.
Wood windows are a double-edged sword, however — what you gain in beauty, you lose in ease of care. Wood frames require more maintenance than any other option on our list. Expect annual sealing, bi-annual caulking, and repainting your frames every 5 years.
Are wood windows energy efficient?
Wood windows are surprisingly efficient if properly maintained. Wood’s natural ability to protect against air leaks and heat loss means a net positive energy efficiency score — if you keep up with regular maintenance.
Homeowners that don’t regularly maintain and repair their wood frames will see little to no energy efficiency benefits. As cracks and chips form, air leaks naturally occur. The money you save on energy bills goes directly into annual maintenance of your window frames.
The pros and cons of wood windows
Pros:
Strong lifespan of 30+ years with proper annual maintenance
Beautiful natural look adds value to wood-based home design
Easy to customize and pair with home design colors, grains and tones
Better than average energy efficiency rankings
Cons:
Higher upfront cost than virtually all other popular window materials
Require annual maintenance and sealing to avoid rot, mildew and damage
Regular repairs needed to account for chips, cracks and warping
Condensation damage accumulates over time, regular caulking needed
Prolonged exposure to rain and snow leads to timber swelling
What do wood windows cost?
The average wood window frame costs $750-$1,250 to purchase and install. Double-hung wood windows are actually slightly less expensive than the average wood frame, at $650-$1,050 per window.
Wood windows are valued for their customization and beauty in larger window installation styles. For example, a 3-window wood bay window feature costs $2,500-$3,500 to buy and install.
