The 5 Most Popular Types of Frames Available for Replacement Windows 


When shopping for replacement windows, you must consider more than the glass type, tinting, and number of panes. You must also factor in the fact that you will need brand new window frames.

The 5 most popular types of frames available for replacement windows include aluminum, composite, vinyl, fiberglass, and traditional wood. The style, the durability, and the energy efficiency of each vary to some degree or another.

The window frame is the proverbial “backbone” to your replacement window. Continue reading to learn a bit about each of the types of frames that we have outlined. 


Aluminum is a material that is known for its high level of durability and longevity. Frames composed of aluminum are perfect for homes that reflect the most modern architectural styles. These are designed to let in am ample level of natural light into the home and require very little – in terms of maintenance.

Environmental conditions will not result in the development of rot or encourage mold growth. The one issue associated with aluminum is that it conducts heat. This means in very warm climates; the frame may contract and expand. Additionally, aluminum offers virtually no benefits as far as energy efficiency. 


Composite window frames are defined as those that consist of both wood and either aluminum or vinyl. Many professionals may identify these types of frames as “clad wood”. In short, they consist of a combination of materials.

These types of frames will give you the classic appearance of wood with the combined strength of the secondary material utilized in the creation process. These frames are highly resistant to weather conditions. The only issue is, they are quite expensive. 


Vinyl window frames are composed of polyvinyl chloride (PVC). As a result, these types of frames are among the least expensive on the market. You may choose from many types of design options. These structures are highly insulative, which means that they have a high level of energy efficiency.

While it is true that these frames are capable of standing up against the most severe of conditions, vinyl is not as strong as the other types of materials that manufacturers make frames out of. Additionally, they lack the unique appeal and charm of other types of materials used in window frames. 


Fiberglass frames are quite strong and very easy to maintain. Fiberglass is a material that is resistant to weather and to immense levels of heat and humidity. They require little maintenance. If properly cared for, they have the ability to last up to 80 years!

These types of frames are available in many different styles and designs. Best of all, fiberglass has a high level of energy efficiency. The only issue is, many homeowners feel as if these types of frames lack the beauty and appeal of other types of frames for the price. 

Traditional Wood

Traditional wood window frames are highly durable and have a classic appearance, which makes a home of any architectural style look fantastic. Wood is a material that insulates well and is weather resistant.

It is exceptionally popular among homeowners that want an eco-friendly option when remodeling their home. Wood does require a bit of maintenance, though. While durable, traditional wood frames may only last a few decades and are susceptible to wood rot and the growth of mold, mildew, and fungus.
