Aluminium Windows: Features, Advantages, and Cost Factors

Aluminium windows are a modern solution that is gaining increasing importance in contemporary architecture and construction. They are suitable for both new builds and renovations and offer an appealing combination of strength, durability, and sleek design. In this article, we provide a comprehensive overview of the features, advantages, and cost factors of aluminium windows.

Features and Design

Aluminium windows consist of a metal frame made of aluminium, known for its strength and lightness. These properties make aluminium an ideal material for window frames. Through modern processing techniques, aluminium window frames can be constructed to meet energy efficiency requirements while remaining stable and durable.

Types of Windows

There are various types of aluminium windows, differing in their opening mechanism and design:
– Tilt-and-turn windows: Flexible ventilation and easy cleaning.
– Sliding windows: Ideal for large glass areas and space-saving.
– Fixed glazing: Maximum light transmission, ideal for areas without ventilation needs.
– Folding doors: Almost complete wall opening, perfect for terraces or gardens.

Special Features of Aluminium Windows

– Durability: Aluminium windows are robust and resistant to deformation, cracks, or discoloration.
– Stability: High load-bearing capacity and shape retention even under extreme weather conditions.
– Weather resistance: Highly resistant to moisture and corrosion.
– Ease of maintenance: Smooth surfaces are easy to clean and maintain.
– Energy efficiency: Modern windows with thermal breaks provide good thermal and sound insulation.
– Design variety: Available in various colors and designs, scratch-resistant and colorfast through powder coating or anodizing.

Key Data on Aluminium Windows

– Energy efficiency: Modern aluminium windows achieve U-values between 1.2 and 0.8 W/(m²K).
– Sound insulation: Sound insulation values of Rw = 35 dB to 45 dB or higher.
– Burglary protection: Available in various resistance classes (RC1 to RC3).
– Glazing options: From double to triple glazing, also special options such as soundproof, safety, or solar protection glass.
– Lifespan: Thanks to high corrosion resistance and material strength, a lifespan of 30 years or more.
– Sustainability: Aluminium is recyclable, reducing environmental impact.

Advantages and Disadvantages


– Durable and low maintenance: Saves time and costs in the long run.
– High stability: Ideal for large glass areas.
– Energy efficiency: Good insulation leads to energy savings.
– Design variety: Flexibility in design.
– Environmentally friendly: 100% recyclable.


– Cost: Higher initial costs compared to other materials.
– Thermal conductivity: Can lead to heat loss without thermal breaks, though modern solutions have largely addressed this issue.


The prices for aluminium windows vary depending on size, design, glazing options, color, and security features. Additional features such as special glass types or electronic opening systems can increase the costs.

Tips for Installation and Maintenance

Professional installation from an aluminium window manufacturer is critical to the energy efficiency and longevity of the windows themselves. Regular maintenance, such as checking seals and fittings, also contributes to optimal performance and longevity.

Aluminium windows are an excellent choice for modern construction projects that value durability, design variety, and energy efficiency. Despite higher initial costs, they offer long-term savings and a sustainable investment through their numerous advantages.
