Window frames play an important role in protecting your home from drafts, pests, and the elements. Plus, let’s be honest, the right ones can really add character to a room.

Before you overhaul your windows, read on to learn everything you need to know about different types of window frame materials.

There are seven main types of window frame materials on the market, each with its own benefits and drawbacks. And, while choosing a window frame for your home may seem like a breeze, the wrong window frame material can:

  • Increase your energy bills.

  • Require time-consuming maintenance.

  • Make your home uncomfortable in the winter or summer.

  • Create an eye sore if it clashes with your home’s style.

Not to mention, the average window replacement cost averages around $650 per window, so you’ll want to invest in the right window frame materials to avoid paying high upfront costs on the wrong materials for your project. With this in mind, as you browse through your options, consider the pros and cons of each material before deciding on a window frame.

MaterialQualitiesCost Per Window
AluminumCost-friendly and low-maintenance, but a poor insulator that’s prone to condensation and corrosion.$75 – $400
VinylEnergy-efficient and low-maintenance, but less natural-looking, flimsy, and may warp or discolor.$100 – $900
WoodTimeless appearance and great insulation, but high maintenance, high costs, and prone to pests and rot.$150 – $1,300
FiberglassLong-lasting, and ideal for fluctuating weather, but higher price and limited customizations.$500 – $1,500
CompositeAesthetically appealing and low-maintenance, but higher in price and differing quality by manufacturer.$300 – $1,200
Wood CladCombines best of wood and rot-resistant materials, but has a higher price and can separate over time.$250 – $2,000
SteelModern look, sturdy, and durable, but has a higher price point and is prone to rust.$400 – $1,500

1. Aluminum Window Frames

Aluminum offers a flexible option for homes with larger windows, as they’re easy to customize and offer good support for heavy sheets of glass. While aluminum is the most budget-friendly window frame material—coming in at just $75 to $400 per window—it’s one of the least-appealing options for energy efficiency. Aluminum conducts hot and cold temperatures, so you’ll spend more money to regulate your home’s interior temperatures. 

Additionally, the exterior is more likely to have condensation, which can develop beads of water that deteriorate the window casing that goes around the frame, leading to rot. Aluminum is also more susceptible to corrosion via salt water and ocean mist. As such, it’s only really suitable for mild or warm climates.


  • Lightweight

  • Strong

  • Flexible

  • Low-maintenance

  • Subtle

  • Cost-friendly

  • Long-lasting


  • Poor insulator

  • High conductivity

  • Condensation

  • Susceptible to corrosion 

2. Vinyl Window Frames

Vinyl window frames are popular and economical because they fall at the lower end of the price point at only $100 to $900 each. But homeowners also love them because they're energy-efficient windows that are fire-resistant and low-maintenance. 

Where vinyl window frames fall short lies in their appearance and strength—they’re hard to paint or stain, and vinyl can warp when exposed to high temperatures.


  • Budget-friendly

  • Energy-efficient

  • Recyclable

  • No need to paint or stain

  • Minimal peeling or cracks

  • Low-maintenance

  • Many style choices

  • Fire-resistant

  • Prevents outside noises


  • Unable to stain or paint

  • Less natural looking

  • Less strong than fiberglass, composite, and metal

  • Can warp under high heat

  • May discolor over time

3. Wooden Window Frames

Wood windows take the cake for a traditional look that adds charm to historical and classical homes. Wooden window frames come in many different styles, depending on the type of wood, paint, and stain you choose, making them versatile. At the same time, wood windows require a lot more TLC than other options, as they’re vulnerable to pests, rot, and warping.

Wood window frames come in towards the upper tier of the price point, at $150 to $1,300 per window. You’ll save on the level of insulation that wood has to offer for your home and spend more on maintenance.


  • Warm and inviting appearance

  • Versatile 

  • Excellent insulator

  • Saves money in energy bills

  • Most sound-proof material 

  • Long-lasting

  • Rust-resistant


  • High maintenance

  • Requires repainting

  • Insect-prone

  • High upfront costs

  • Prone to warping and cracking in heat

  • Vulnerable to rot

  • Fire hazard

4. Fiberglass Window Frames

If you're upgrading your window frames, fiberglass is a durable, element-resistant material with more to offer than other budget-friendly options like vinyl and aluminum. Fiberglass windows contain an interwoven proprietary blend of glass fibers and a strong resin core, allowing them to expand and contract no matter the weather. 

The main downsides are that you have fewer color and design options, and fiberglass is one of the priciest options. Fiberglass window frames cost anywhere from $500 to $1,500 each, but you’ll save on energy costs and maintenance with this option.


  • Heat-resistant

  • Cold-resistant

  • Waterproof

  • Strong and durable

  • Low-maintenance

  • Great insulator

  • Resistant to extreme weather conditions

  • Energy-efficient

  • Noise resistant


  • High price tag

  • Few customization options

  • Less readily available

  • Prone to UV damage

  • Harder to install

5. Composite Window Frames

Composite window frames resemble the appearance of wood, but utilize a combination of recycled wood, metals, or plastics to create a more sustainable, natural product. However, since composite window frames contain differing materials by manufacturer, it can be challenging to know exactly what you're buying and which brand to choose. 

Composite windows cost anywhere between $300 to $1,200, making them higher in price compared to vinyl or aluminum, but more budget-friendly overall than wood, clad, or steel.


  • Mimics wood appearance

  • Requires less maintenance than wood

  • Eco-friendly

  • Long-lasting

  • Great insulator

  • Rot-resistant

  • Seamless look


  • High upfront costs

  • Quality differs by manufacturer

6. Wood-Clad Window Frames

Wood clad window frames are wood window frames enhanced with a protective shell made of either aluminum or vinyl. The aluminum or vinyl encasement protects the wood from water damage so that you can still have that stunning, natural wood without the high maintenance that comes with it. 

You’ll pay anywhere from $250 to $2,000 for wood-clad window frames. Vinyl-clad wood windows are slightly more affordable than aluminum-clad wood frames. 


  • Aesthetically appealing

  • Great thermal insulation

  • Energy efficient

  • Durable

  • Low-maintenance

  • Customizable

  • Recyclable


  • Higher cost

  • Cladding can separate

7. Steel Window Frames

Modern homes sometimes need a more industrial touch, and steel window frames offer exactly that. Steel is durable, fire-resistant, and hard to break, making it a great choice for homeowners looking for added security.

This premium option is sturdy, sleek, and often custom-built, so anticipate a higher price tag for steel window frames. Steel windows cost between $400 and $1,500 per window, but they require minimal maintenance and can last over 75 years.


  • Modern style

  • Extremely durable

  • Energy-efficient

  • Long-lasting

  • Fire-resistant

  • Customizable

  • Secure

  • Recyclable


  • High upfront costs

  • Susceptible to corrosion

  • Heavy

  • Difficult to cut

How to Pick the Best Window Frame Type for Your Home

The best window frame for your home depends on your budget, style, window size, and climate. Overall, vinyl window frames offer the best value for the price, but if you’re looking for a timeless, modern, or more durable look, you may want to consider clad wood windows, fiberglass window frames, or steel-framed windows. 

When in doubt, check with a window replacement company near you that can better guide you as to which window frame works best in your local area.
