Is It Necessary to Use Thermal Break Aluminum for Enclosing Balconies?
When it comes to enclosing a balcony, many homeowners wonder whether investing in thermal break aluminum doors and windows is a must. To make an informed decision, it’s essential to consider several factors—such as glass type, safety railing options, and frame materials.

- Which Type of Glass to Choose?
Selecting the right glass is critical for impact resistance, thermal insulation, and noise reduction. Tempered glass is widely considered the top choice due to its high strength and safety—it is less likely to shatter upon impact. This type of glass can be configured as single-pane, double-pane insulated, or laminated. However, double-pane insulated glass is most frequently recommended. Composed of two glass layers, it significantly improves energy efficiency, reduces outside noise, and offers better thermal performance. - Should the Safety Railing Be Removed?
While some prefer a cleaner look by removing railings, it’s important to assess their condition and height. Corroded railings or those under 1.1 meters in height offer minimal protection and should be taken down. In such cases, installing an invisible security grille outside the window is a smart alternative. This prevents children from climbing out and items from falling. Some railings are mounted inside, while others are fixed outside—external ones can be enclosed during the renovation with a small gap left for drying quilts or other items. - Is Thermal Break Aluminum Really Necessary?
Window frames are commonly made from three materials: uPVC, standard aluminum, and thermal break aluminum. uPVC is affordable with good insulation and sealing performance, but its bulky frame obstructs views and natural light. Standard aluminum is cost-effective, durable, and low-maintenance, but it performs poorly in thermal insulation.
Thermal break aluminum, on the other hand, combines the benefits of both—durability and excellent insulation. The downside is its higher cost and more complex installation. Enclosing a balcony with this material can easily cost over ten thousand. So, is it worth it?
The key advantages of thermal break aluminum lie in its thermal and acoustic insulation. If your home uses air conditioning in summer and heating in winter, pairing thermal break frames with double-pane glass will help maintain a stable indoor temperature. For those living near noisy roads or highways, it significantly reduces outdoor noise, ensuring a quieter and more comfortable living environment.
