Comparing PVC and Aluminum

Durability and Resistance

PVC: PVC (polyvinyl chloride) is a plastic material known for its resistance to corrosion, humidity, and salt spray. PVC windows and doors are durable and can withstand adverse weather conditions such as rain, wind, and intense sun without suffering damage or deformation. However, PVC can be susceptible to scratches and impacts, and its resistance may vary depending on the quality of the material and its exposure to extreme temperatures.

Aluminum: Aluminum is a lightweight and sturdy metal, known for its durability and resistance to corrosion, impacts, and deformations. Aluminum windows and doors are robust and can support large spans and weights, making them ideal for large works and projects with specific resistance requirements. Aluminum is also resistant to extreme temperatures and can be anodized or painted to increase its durability and protection against corrosion.


Thermal and Acoustic Insulation

PVC: PVC is a good thermal and acoustic insulator, thanks to its cellular structure and low thermal conductivity. PVC windows and doors can help reduce heat loss and minimize exterior noise, providing a more comfortable and quiet environment indoors. The quality of PVC's thermal and acoustic insulation can vary depending on the thickness of the profiles, the type of glass used, and the presence of thermal break systems.

Aluminum: Aluminum, being a metal, is a conductor of heat and sound. However, modern aluminum windows and doors incorporate thermal break systems, which consist of inserting an insulating material between the aluminum profiles, significantly reducing heat and sound transfer. With thermal breaks, aluminum windows and doors can offer excellent thermal and acoustic insulation, comparable to PVC.


Energy Efficiency

PVC: PVC windows and doors contribute to the energy efficiency of buildings, reducing heat loss and the need for heating and air conditioning. PVC, combined with double or triple glazing with low emissivity, can ensure high energy performance, helping to reduce energy costs and minimize environmental impact.

Aluminum: Aluminum windows and doors with thermal breaks also offer good energy performance, minimizing heat loss and contributing to the sustainability of buildings. 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.


Safety

PVC: PVC windows and doors can offer a good level of security, especially when equipped with reinforced hardware and lock systems. However, PVC may be more vulnerable to break-ins than aluminum, depending on its quality and how it is installed.

Aluminum: Aluminum windows and doors are robust and resistant to impacts, offering greater security against break-ins. Aluminum can be combined with safety glass and anti-intrusion hardware, ensuring the protection of property and people.
