Key Features of Our Aluminium Windows Products:

For architects, developers, and self-builders aiming for Passive House standards or a fabric-first approach, triple glazed aluminium windows and doors from QFORT and DAKO offer a seamless blend of design excellence, structural integrity, and exceptional thermal performance.

These high-end systems are engineered to support large expanses of glazing with minimal framing—DAKO’s DA-Skyline patio doors offer sightlines as slim as 25 mm, while QFORT’s minimalist sliding systems achieve elegant transparency with frame concealment solutions. 

Style in the finish

The strength of aluminium allows for ultra-slim profiles without compromising on stability or durability, making them ideal for modern architecture, open-plan living, and commercial applications. 

Both brands offer fully customisable design options, including a wide range of colours, finishes, and configurations, allowing for complete architectural freedom while enhancing building aesthetics with clean, modern lines.

The Perfect Balance of Performance and Style

Performance-wise, QFORT and DAKO aluminium window and door systems are engineered for maximum energy efficiency, supporting ultra-low energy consumption and airtightness.

With triple glazing as standard, U-values across both ranges vary from as low as 0.8 W/m²K to 1.3 W/m²K, depending on configuration—suitable for even the most demanding Passive House or low-energy home requirements. Thermally broken frames, multi-chamber profiles, and warm edge spacers ensure outstanding insulation and condensation control. These high-performance aluminium systems significantly reduce heat loss and enhance indoor comfort throughout the year. Ideal for new builds, contemporary extensions, or commercial façades, QFORT and DAKO products combine minimalist aesthetics with advanced performance, making them the perfect choice for sustainable construction projects that prioritise energy efficiency, durability, and cutting-edge design.
