Learning About Window Frame Materials

When looking into a new custom window, there are more factors to consider than just the glass itself. At Precision Glass Services, our experts will walk you through each of the important areas you need to look at when considering new window installation.

One such factor that’s often very important in commercial buildings is the window frame material. There are several options for frame materials, each of which comes with their own advantages and drawbacks. Let’s take a look at several of the most popular materials.


Vinyl costs less to produce, but that doesn’t mean it’s “cheap” necessarily. Vinyl can offer excellent energy efficiency if installed correctly, and can help reduce air leakage. However, vinyl frames can also be limited in color choices, and some people don’t like their aesthetic look.


From an insulation standpoint, wood window frames are the top choice. Wood is well-known for its insulative properties, though this also means that it will require more upkeep than vinyl to make it last. Wood does come with the potential for rot, and as such it may not be the best choice in certain humid or rainy climates. But a well-built wood window will last years.


For the kinds of rainy and humid climates that wood frames might not function well in, aluminum can be a great alternative. It doesn’t quite have the insulative properties of wood, but it does meet stringent coastal building codes in hurricane-prone areas. Aluminum is among the strongest frame materials out there.


Wood-clad windows ostensibly offer the best of both words between wood and aluminum: low maintenance, but also good temperature resistance. They can be vulnerable to water intrusion, however, and detailed care needs to be taken during installation.


Made from scrap wood shavings and plastic resins, these composite frames can mimic wood but come with far less maintenance. These composites are also a great eco-friendly choice, as they’re often made from recycled plastics.


Fiberglass is a type of composite, but is made from a mixture of glass fiber and polyester resins. Fiberglass is more expensive than other similar units, but they make up for this by being extremely energy efficient and very strong. They’re also the most durable windows on the market, and can be repainted several times if necessary.
