What Are The Disadvantages of Aluminum Doors

Aluminium doors are widely used in modern architecture and residential projects thanks to their lightweight design, durability, and stylish appearance. However, for distributors and end users, it is equally important to understand the disadvantages of aluminium doors. This article explores the common drawbacks of aluminium doors, supported by authoritative references, and explains how VIGORAWINDOWS, a professional aluminium door company from China, helps global distributors overcome these challenges.

Heat Insulation Performance is Relatively Weak

Compared with wooden or UPVC doors, aluminium is a highly conductive material, which means poor thermal insulation in extreme climates.

According to the U.S. Department of Energy (DOE):

“Metal frames, including aluminium, conduct heat rapidly, which can reduce the energy efficiency of a building if not thermally broken.” (Source: U.S. Department of Energy, Energy Saver, 2023)

To improve this, top aluminium door manufacturers often adopt thermal break technology or combine aluminium frames with multi-layer insulated glass.

Higher Initial Investment Cost

Compared with PVC or some timber doors, aluminium doors generally come with a higher upfront cost—especially for large-scale products such as Aluminium Sliding Doors, Aluminium French Doors, or Aluminium folding doors.

However, from a distributor’s perspective, high-quality aluminium doors offer longer service life and fewer maintenance issues, which helps reduce long-term costs. Therefore, when cooperating with aluminium door suppliers, overseas distributors should weigh initial investment vs. long-term returns.

Susceptible to Corrosive Environments

Although aluminium has strong anti-rust properties, it may still be affected in coastal salt-air environments or acidic/alkaline industrial conditions. The surface oxide layer can deteriorate, shortening the product’s lifespan.

Professional aluminium door factory operations apply powder coating, anodizing, or electrophoresis finishes to enhance corrosion resistance. At VIGORAWINDOWS, we provide tailored solutions based on market environments, ensuring better performance for distributors in coastal or industrial regions.

Installation and After-Sales Dependence

Compared with PVC doors, aluminium doors require more advanced installation skills. Specialized tools and professional installers are often necessary, which can be challenging for end-users without local support.

This is why VIGORAWINDOWS focuses on the B2B market (overseas distributors) rather than the C-end market. Distributors already have local installation capacity, while we provide fast delivery, diverse products, and guaranteed quality to support them.

How VIGORAWINDOWS Helps Distributors

In summary, the main disadvantages of aluminium doors include:

• Weak thermal insulation

• Higher upfront cost

• Vulnerability in corrosive environments

• Heavy reliance on installation and after-sales services

However, as a leading aluminium door company, VIGORAWINDOWS helps global distributors address these issues through:

• Diverse product lines – including aluminium casement door, Aluminium Sliding Doors, Aluminium French Doors, Aluminium folding doors, and more.

• Competitive pricing – leveraging China’s manufacturing scale for cost advantages.

• Fast delivery – with a reliable supply chain and factory capacity.

• Superior quality – applying thermal break, anti-corrosion coatings, and strict QC.

• Customization options – offering tailored dimensions, finishes, and glass systems for different markets.

For overseas window and door distributors, working with experienced aluminium door manufacturers like VIGORAWINDOWS turns these disadvantages into new opportunities for market growth.
