Enclosing a balcony with aluminum allows you to significantly improve the comfort of your stay throughout the year: reducing wind, cold and heat penetration, along with reducing street and neighbor noise. Combining high-quality aluminum profiles, appropriate glazing and precise perimeter sealing help create a stable, pleasant and more energy-efficient envelope - especially in apartments on high floors and in exposed areas.

Balcony enclosures can be designed to maintain an elegant, open look: sliding or folding windows, thin frames for maximum light, and custom shades. For sun balconies, it is recommended to incorporate complementary shading solutions such as wood-like aluminum pergolas, blinds, or screens, to control the intensity of light and heat without sacrificing the sense of space.

Correct work process: measurement, safety and compliance

Professional balcony enclosure begins with an inspection of the site conditions and preparation of an engineering/performance plan in accordance with the existing structure. It is important to ensure safety: strong anchors, corrosion-resistant materials, proper drainage, and sealing of joints to prevent leaks. In addition, it is recommended to ensure compliance with the requirements of the condominium and the relevant authorities, to ensure clean, proper, and quiet execution over time.
