Aluminum and UPVC are two common materials which made for window and doors. Both UPVC and aluminum windows have their own advantages and disadvantages. The choice between the two depends on factors such as budget, desired aesthetics, energy efficiency requirements, and personal preferences. The reason why I recommend aluminum windows and doors are as belows: - Aluminum windows are made from a lightweight and strong metal material. - They are known for their sleek and modern appearance. - Aluminum windows are highly durable and resistant to weathering, rust, and corrosion. - They require minimal maintenance and are easy to clean. - Aluminum windows are available in a wide range of colors and finishes. - They provide good strength and security, as aluminum is a strong material. - Aluminum windows are generally more expensive than UPVC windows. - They have a higher thermal conductivity compared to UPVC windows, which may result in less energy efficiency.
