Types of Window Frames

and How they Impact the Energy Efficiency of Prefabricated Homes

Windows are a significant deciding factor on the energy efficiency of your prefabricated home. We break down the types of window frames, one of the four factors to consider when choosing the most energy-efficient windows.


Vinyl windows are low-maintenance and known for their durability regardless of the climate. First, they are generally the most budget-friendly material while providing high energy efficiency. As a flexible and durable type of plastic, vinyl is an effective insulator, meaning no heat will transfer through it. This means that heat will stay in your home in the winters. Vinyl windows are also great for keeping heat out in the summers.


Fiberglass windows are expensive but come with many benefits. First, fiberglass is a durable product that provides high energy efficiency performance. Additionally, fiberglass is great in hot climates as it can take the heat. Lastly, the combination of plastic and glass used to make fiberglass makes it a more environmentally friendly and long-lasting option.


Aluminum windows are a more expensive option compared to vinyl windows; however, they offer less energy efficiency. Nonetheless, aluminum windows have high strength and lightweight qualities. This helps support larger glass sizes while achieving a minimalist look. Energy performance is the major downside to aluminum frame windows. As metals conduct heat easier, aluminum is not a viable option for keeping heat out in summers.


There are a variety of composite window types. An example of a composite material window frame is one made from combining wood particles and resin. This allows for the thermal performance of wood without vulnerability to moisture or decay. Another composite window example combines the strength of aluminum while providing the efficiency of vinyl. Lastly, composite windows can offer high efficiency and durability depending on the manufacturer.


Wood windows are the best choice for looks and aesthetics. First, wood windows are easier to customize. Customizations include choosing how to paint, stain and shape the frame. Wood windows will require more maintenance over time as they are vulnerable to moisture, warping, or rot. If maintained properly, wood windows are highly energy-efficient over a long time.
