What’s the Difference Between Aluminum and Plastic Window Frames?

Choosing the type of glazing is a very important issue that every homeowner faces. Let’s try to figure out the difference between aluminum and plastic window frames.

PVC structures used to be the most popular choice, and recently aluminum window frames have become a worthy competitor. The main reason for the growing popularity of aluminum systems is the insulation of the section using innovative materials.

Let’s compare plastic and aluminum window frames:

• Lifespan. Plastic window frames can last up to 30 years, while aluminum ones can last over 40 years.
• Shape. Most plastic window frames come in a standard shape. Aluminum window frames are also mostly rectangular, however, unlike plastic systems, aluminum designs feature sliding leafs, which are much more convenient in limited spaces.
• Weight. Aluminum is lightweight yet highly durable. PVC windows are quite heavy, so when installing them on a balcony, for example, the supporting structure reinforcement would be needed.
• Safety. In some situations, PVC window frames pose environmental risks, whereas aluminum ones are environmentally friendly in all situations.

In addition to these factors, the specific operational characteristics of plastic and aluminum window frames are considered when making a choice. PVC window frames require more careful handling to prevent scratching of sections. Unlike aluminum, such structures are more prone to thermal expansion. Therefore, it is not advisable to install painted PVC sections on the south side, as they will heat up to a critical temperature there.
