Securing the balcony is a highly important issue in home renovation, and the cost of balcony enclosure depends entirely on the materials used. From a pricing perspective, which material would be the most suitable for enclosing a balcony?
Currently, the main materials used for balcony enclosures in the building materials market include PVC windows and doors, aluminum-clad wood windows and doors, thermally broken aluminum windows and doors, and aluminum alloy windows and doors. Below, we’ll provide you with a detailed introduction: 
1. PVC Windows:
The advantages of PVC windows include excellent weather resistance, as well as good thermal and sound insulation performance. However, PVC materials come in relatively limited color options, lack sufficient strength, and aren’t very resistant to wind pressure. If the windows aren’t closed properly during strong winds, they can easily get damaged. Additionally, PVC windows don’t last very long and tend to fade over time. Despite these drawbacks, because enclosed balconies made with PVC are still quite affordable, many people continue to choose this material for their window installations.
2. Aluminum Alloy Windows:
Aluminum alloy windows offer excellent weather resistance and anti-aging properties, but their insulation performance is less than ideal. As for color options, they’re limited to just white and brown. Since aluminum is a highly conductive material, it leads to unnecessary energy loss—especially in summer, when even with air conditioning running, it’s hard to cool down the room effectively. This happens because aluminum windows continuously transfer outdoor heat into the interior. Similarly, in winter, it’s challenging to keep the space warm. Nevertheless, aluminum alloy windows remain one of the more affordable materials for balcony enclosures.
3. Thermal Break Aluminum Windows:
Aluminum with thermal breaks is sturdy and durable, and its composite structure also effectively blocks the transfer of heat, making it an ideal choice for balcony enclosures. However, opting for aluminum with thermal breaks as the material for your balcony enclosure will result in a higher price. Additionally, non-standard window designs typically have longer production times and are heavier, which means they require more precise installation compared to materials used for standard windows.
4. Aluminum-clad Wood Windows
Aluminum-clad wood windows are relatively expensive, making them a "luxury" product in the window and door industry. The biggest advantages of aluminum-clad wood doors and windows are their exceptional thermal insulation, energy efficiency, resistance to wind and sand, and stunning aesthetics! By encasing solid wood with an additional layer of thermally broken aluminum alloy, these products achieve superior sealing performance. In scorching summer heat, they effectively block out outdoor swelter, minimizing the loss of cool air indoors. And during chilly winter months, they prevent ice and condensation from forming—plus, they keep noise levels outside, ensuring a quieter, more comfortable living environment.
Friends who love wood-inspired interior designs will definitely not overlook aluminum-clad wooden windows—especially if their budget allows.
Above is the editor's macro-level price comparison based on window and door materials. Here’s a reminder: when choosing materials for balcony enclosure, price shouldn’t be your primary consideration—instead, prioritize selecting high-quality materials that align with your family’s specific needs.
