Aluminium Front Doors
Style Meets Security
Installing a new front door not only enhances your home’s appearance but can also significantly improve energy efficiency and increase burglary protection.
Today’s front doors come in a wide range of sizes, materials, and designs — and among them, aluminum has become a standout choice.
Lightweight yet exceptionally strong, aluminium has gained popularity in modern construction for its durability, stability, and minimal maintenance. An aluminum front door combines long-lasting performance with a sleek, contemporary aesthetic — making it an ideal solution for both security and comfort.

High Weather Resistance
What Makes an Aluminium Front Door Stand Out
One of the defining qualities of aluminium front doors is their exceptional resistance to weather conditions. Even under extreme or long-term exposure, aluminium maintains both its functional strength and its elegant appearance.
When the material comes into contact with air or moisture, it naturally forms a protective aluminium oxide layer, ensuring long-lasting corrosion resistance.
Additionally, high-quality textured powder coatings make aluminium doors more resistant to minor scratches while keeping them easy to maintain. With minimal upkeep — often just a simple wipe — your aluminium front door stays clean, durable, and visually appealing for years.

Excellent Thermal Performance
Superior insulation with modern engineering
Thanks to advanced engineering, today’s aluminium doors feature greater construction depth, multi-layer insulation, and a built-in thermal break — all working together to ensure outstanding energy efficiency.
This means a high-quality aluminium front door can easily meet the demands of low-energy and even passive houses.
Best of all, you don’t have to choose between performance and aesthetics. Aluminium front doors come in a wide variety of modern designs, offering both superior insulation and stylish visual appeal.
