The combination of aluminum with high-performance glass and efficient sealing systems allows achieving high levels of energy efficiency, making aluminum windows and doors a sustainable and economically viable option.

Design and Aesthetics

PVC: PVC windows and doors are available in a variety of colors, finishes, and styles, allowing them to adapt to different projects and aesthetic preferences. PVC can be lacquered or coated with films that imitate wood, offering a more traditional or contemporary look. However, PVC may have a less sophisticated appearance than aluminum, and its range of colors and finishes may be more limited.

Aluminum: Aluminum is a versatile material that allows for the creation of windows and doors with modern and minimalist designs, adapting to different architectural styles. Aluminum windows and doors can be anodized or painted in a wide range of colors, including metallic finishes and special effects, offering endless customization possibilities. Aluminum also allows the creation of thin and elegant profiles, maximizing the glazed area and the entry of natural light.

Maintenance

PVC: PVC windows and doors require little maintenance, being easy to clean with water and neutral detergent. PVC does not require painting or specific treatment, and its surface is resistant to stains and scratches. However, PVC profiles may yellow over time, especially if exposed to a high incidence of UV rays.

Aluminum: Aluminum windows and doors are also easy to maintain, requiring only regular cleaning with water and neutral detergent. Aluminum does not rust and its surface is resistant to scratches and impacts. However, aluminum windows and doors may require periodic lubrication of opening and closing mechanisms.

Price

PVC: PVC windows and doors are generally more affordable than aluminum, especially in small to medium-sized residential projects. The cost of PVC can vary depending on the quality of the material, the type of profile, and the finishes chosen.

Aluminum: Aluminum windows and doors tend to be more expensive than PVC, due to the cost of the material and its manufacturing. However, aluminum offers greater durability and resistance, which can justify the initial investment in the long term.
